Can a SeekBar be vertical? I am not very good at UI design开发者_高级运维, so how can I make the SeekBar more beautiful, please give me some templates and examples.

1. For API 11 and later, can use seekbar's XML attributes(android:rotation="270") for vertical effect.

   <SeekBar
   android:id="@+id/seekBar1"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:rotation="270"/>
   

2. For older API level (ex API10), only use Selva's answer:
   https://github.com/AndroSelva/Vertical-SeekBar-Android

Here is a very good implementation of vertical seekbar. Have a look.

http://560b.sakura.ne.jp/android/VerticalSlidebarExample.zip

And Here is my own implementation for Vertical and Inverted Seekbar based on this

https://github.com/AndroSelva/Vertical-SeekBar-Android

protected void onDraw(Canvas c) {
    c.rotate(-90);
    c.translate(-getHeight(),0);

    super.onDraw(c);
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (!isEnabled()) {
        return false;
    }

    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
        case MotionEvent.ACTION_MOVE:
        case MotionEvent.ACTION_UP:
            int i=0;
            i=getMax() - (int) (getMax() * event.getY() / getHeight());
            setProgress(i);
            Log.i("Progress",getProgress()+"");
            onSizeChanged(getWidth(), getHeight(), 0, 0);
            break;

        case MotionEvent.ACTION_CANCEL:
            break;
    }
    return true;
}

Working example

import android.content.Context;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class VerticalSeekBar extends SeekBar {

    public VerticalSeekBar(Context context) {
        super(context);
    }

    public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public VerticalSeekBar(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        super.onSizeChanged(h, w, oldh, oldw);
    }

   @Override
   public synchronized void setProgress(int progress)  // it is necessary for calling setProgress on click of a button
   {
    super.setProgress(progress);
    onSizeChanged(getWidth(), getHeight(), 0, 0); 
   }
    @Override
    protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(heightMeasureSpec, widthMeasureSpec);
        setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());
    }

    protected void onDraw(Canvas c) {
        c.rotate(-90);
        c.translate(-getHeight(), 0);

        super.onDraw(c);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (!isEnabled()) {
            return false;
        }

        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
            case MotionEvent.ACTION_MOVE:
            case MotionEvent.ACTION_UP:
                setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
                onSizeChanged(getWidth(), getHeight(), 0, 0);
                break;

            case MotionEvent.ACTION_CANCEL:
                break;
        }
        return true;
    }
}

There, paste the code and save it. Now use it in your XML layout:

<android.widget.VerticalSeekBar
  android:id="@+id/seekBar1"
  android:layout_width="wrap_content"
  android:layout_height="200dp"
  />

Make sure to create a package android.widget and create VerticalSeekBar.java under this package

Try:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 

<SeekBar 
    android:id="@+id/seekBar1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:rotation="270" 
    /> 

</RelativeLayout> 

We made a vertical SeekBar by using android:rotation="270":

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <SurfaceView
        android:id="@+id/camera_sv_preview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <LinearLayout
        android:id="@+id/camera_lv_expose"  
        android:layout_width="32dp"
        android:layout_height="200dp"
        android:layout_centerVertical="true"
        android:layout_alignParentRight="true"
        android:layout_marginRight="15dp"
        android:orientation="vertical">

        <TextView
            android:id="@+id/camera_tv_expose"
            android:layout_width="32dp"
            android:layout_height="20dp"
            android:textColor="#FFFFFF"
            android:textSize="15sp"
            android:gravity="center"/>

        <FrameLayout
            android:layout_width="32dp"
            android:layout_height="180dp"
            android:orientation="vertical">

            <SeekBar
                android:id="@+id/camera_sb_expose"
                android:layout_width="180dp"
                android:layout_height="32dp" 
                android:layout_gravity="center"
                android:rotation="270"/>

        </FrameLayout>

    </LinearLayout>

    <TextView
        android:id="@+id/camera_tv_help"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="20dp"
        android:text="@string/camera_tv"
        android:textColor="#FFFFFF" />

</RelativeLayout>

Screenshot for camera exposure compensation:

I used Selva's solution but had two kinds of issues:

• OnSeekbarChangeListener did not work properly
• Setting progress programmatically did not work properly.

I fixed these two issues. You can find the solution (within my own project package) at

https://github.com/jeisfeld/Augendiagnose/blob/master/AugendiagnoseIdea/augendiagnoseLib/src/main/java/de/jeisfeld/augendiagnoselib/components/VerticalSeekBar.java

This worked for me, just put it into any layout you want to.

<FrameLayout
    android:layout_width="32dp"
    android:layout_height="192dp">

    <SeekBar
        android:layout_width="192dp"
        android:layout_height="32dp"
        android:layout_gravity="center"
        android:rotation="270" />

</FrameLayout>

Wrap it inside a FrameLayout so that there is no Size issue.

  <FrameLayout
                android:layout_width="@dimen/_20dp"
                android:layout_marginStart="@dimen/_15dp"
                android:layout_marginEnd="@dimen/_15dp"
                android:layout_height="match_parent"
                android:orientation="vertical">

                <SeekBar
                    android:layout_width="150dp"
                    android:layout_height="30dp"
                    android:layout_gravity="center"
                    android:rotation="270" />
  </FrameLayout>

Note, it appears to me that if you change the width the thumb width does not change correctly. I didn't take the time to fix it right, i just fixed it for my case. Here is what i did. Couldn't figure out how to contact the original creator.

public void setThumb(Drawable thumb) {
    if (thumb != null) {
        thumb.setCallback(this);

        // Assuming the thumb drawable is symmetric, set the thumb offset
        // such that the thumb will hang halfway off either edge of the
        // progress bar.
        //This was orginally divided by 2, seems you have to adjust here when you adjust width.
        mThumbOffset = (int)thumb.getIntrinsicHeight();
    }

When moving the thumb with an EditText, the Vertical Seekbar setProgress may not work. The following code can help:

    @Override
public synchronized void setProgress(int progress) {
    super.setProgress(progress);
    updateThumb();
}

private void updateThumb() {
    onSizeChanged(getWidth(), getHeight(), 0, 0);
}

Usage

Java code

public class TestVerticalSeekbar extends AppCompatActivity {
    private SeekBar volumeControl = null;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_vertical_seekbar);

        volumeControl = (SeekBar) findViewById(R.id.mySeekBar);

        volumeControl.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            int progressChanged = 0;

            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                progressChanged = progress;
            }

            public void onStartTrackingTouch(SeekBar seekBar) {
                // TODO Auto-generated method stub
            }

            public void onStopTrackingTouch(SeekBar seekBar) {
                Toast.makeText(getApplicationContext(), "seek bar progress:" + progressChanged,
                        Toast.LENGTH_SHORT).show();
            }
        });
    }

}

Layout XML

<!-- This library requires pair of the VerticalSeekBar and VerticalSeekBarWrapper classes -->
<com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper
    android:layout_width="wrap_content"
    android:layout_height="150dp">
    <com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBar
        android:id="@+id/mySeekBar"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:max="100"
        android:progress="0"
        android:splitTrack="false"
        app:seekBarRotation="CW90" /> <!-- Rotation: CW90 or CW270 -->
</com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper>

NOTE: android:splitTrack="false" is required for Android N+.

I tried in many different ways, but the one which worked for me was. Use Seekbar inside FrameLayout

<FrameLayout
    android:id="@+id/VolumeLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@id/MuteButton"
    android:layout_below="@id/volumeText"
    android:layout_centerInParent="true">
        <SeekBar
        android:id="@+id/volume"
        android:layout_width="500dp"
        android:layout_height="60dp"
        android:layout_gravity="center"
        android:progress="50"
        android:secondaryProgress="40"
        android:progressDrawable="@drawable/seekbar_volume"
        android:secondaryProgressTint="@color/tint_neutral"
        android:thumbTint="@color/tint_neutral"
    />

And in Code.

Setup Pre Draw callback on Seekbar, Where you can change the Width and height of the Seekbar I did this part in c#, so Code i used was

            var volumeSlider = view.FindViewById<SeekBar>(Resource.Id.home_link_volume);

            var volumeFrameLayout = view.FindViewById<FrameLayout>(Resource.Id.linkVolumeFrameLayout);

            void OnPreDrawVolume(object sender, ViewTreeObserver.PreDrawEventArgs e)
            {
                volumeSlider.ViewTreeObserver.PreDraw -= OnPreDrawVolume;
                var h = volumeFrameLayout.Height;
                volumeSlider.Rotation = 270.0f;
                volumeSlider.LayoutParameters.Width = h;
                volumeSlider.RequestLayout();
            }

            volumeSlider.ViewTreeObserver.PreDraw += OnPreDrawVolume;

Here i Add listener to PreDraw Event and when its triggered, I remove the PreDraw so that it doesnt go into Infinite loop.

So when Pre Draw gets executed, I fetch the Height of FrameLayout and assign it to Seekbar. And set the rotation of seekbar to 270. As my seekbar is inside frame Layout and its Gravity is set as Center. I dont need to worry about the Translation. As Seekbar always stay in middle of Frame Layout.

Reason i remove EventHandler is because seekbar.RequestLayout(); Will make this event to be executed again.

You can do it by yourself - it's now so difficult. Here is an example from my project: https://github.com/AlShevelev/WizardCamera

Let start from settings (attrs.xml).

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="ExpositionBar">
        <attr name="button_icon" format="reference" />
        <attr name="button_icon_size" format="dimension" />

        <attr name="stroke_width" format="dimension" />

        <attr name="stroke_color" format="color" />
        <attr name="button_color" format="color" />
        <attr name="button_color_pressed" format="color" />

        <attr name="min_value" format="float" />
        <attr name="max_value" format="float" />
    </declare-styleable>
</resources>

Here is a couple of utility functions:

fun <T: Comparable<T>>T.fitInRange(range: Range<T>): T =
    when {
        this < range.lower -> range.lower
        this > range.upper -> range.upper
        else -> this
    }

fun Float.reduceToRange(rangeFrom: Range<Float>, rangeTo: Range<Float>): Float =
    when {
        this == rangeFrom.lower -> rangeTo.lower
        this == rangeFrom.upper -> rangeTo.upper
        else -> {
            val placeInRange = (this - rangeFrom.lower) / (rangeFrom.upper - rangeFrom.lower)
            ((rangeTo.upper - rangeTo.lower) * placeInRange) + rangeTo.lower
        }
    }

And at last, but not least - a class for vertical seek bar:

class ExpositionBar
@JvmOverloads
constructor(
    context: Context,
    attrs: AttributeSet? = null,
    defStyleAttr: Int = 0
) : View(context, attrs, defStyleAttr) {

    private val drawingRect = RectF(0f, 0f, 0f, 0f)
    private val drawingPaint = Paint(Paint.ANTI_ALIAS_FLAG)

    private val strokeWidth: Float

    @ColorInt
    private val strokeColor: Int
    @ColorInt
    private val buttonFillColor: Int
    @ColorInt
    private val buttonFillColorPressed: Int

    private val icon: VectorDrawable

    private val valuesRange: Range<Float>

    private var centerX = 0f
    private var minY = 0f
    private var maxY = 0f

    private var buttonCenterY = 0f
    private var buttonRadiusExt = 0f
    private var buttonRadiusInt = 0f
    private var buttonMinY = 0f
    private var buttonMaxY = 0f
    private var buttonCenterBoundsRange = Range(0f, 0f)

    private var iconTranslationX = 0f
    private var iconTranslationY = 0f

    private var isInDragMode = false

    private var onValueChangeListener: ((Float) -> Unit)? = null

    private var oldOutputValue = Float.MIN_VALUE

    init {
        val typedArray = context.obtainStyledAttributes(attrs, R.styleable.ExpositionBar)

        icon =  typedArray.getDrawable(R.styleable.ExpositionBar_button_icon) as VectorDrawable
        val iconSize = typedArray.getDimensionPixelSize(R.styleable.ExpositionBar_button_icon_size, 0)
        icon.setBounds(0, 0, iconSize, iconSize)

        strokeWidth = typedArray.getDimensionPixelSize(R.styleable.ExpositionBar_stroke_width, 0).toFloat()
        drawingPaint.strokeWidth = strokeWidth

        strokeColor = typedArray.getColor(R.styleable.ExpositionBar_stroke_color, Color.WHITE)

You can use it as shown here:

<com.shevelev.wizard_camera.main_activity.view.widgets.ExpositionBar
    android:id="@+id/expositionBar"
    android:layout_width="@dimen/mainButtonSize"
    android:layout_height="300dp"
    android:layout_gravity="end|center_vertical"

    android:layout_marginEnd="@dimen/marginNormal"
    android:layout_marginBottom="26dp"

    app:button_icon = "@drawable/ic_brightness"
    app:button_icon_size = "@dimen/toolButtonIconSize"
    app:stroke_width = "@dimen/strokeWidthNormal"
    app:stroke_color = "@color/mainButtonsForeground"
    app:button_color = "@color/mainButtonsBackground"
    app:button_color_pressed = "@color/mainButtonsBackgroundPressed"
    app:min_value="-100"
    app:max_value="100"
/>

Voila!

Simple answer

Instead of using android:rotation="270" inside of a seek bar, use it inside of a FrameLayout that wraps around it.

 <FrameLayout
    android:background="@color/gray"
    android:layout_width="300dp"
    android:layout_height="5dp"
    android:layout_marginEnd="-126dp"
    android:rotation="270"
    android:orientation="vertical"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintTop_toTopOf="parent">
<SeekBar
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />
</FrameLayout>

To get my frame layout to be 24dp margin right I calculated width -150dp + 24dp because the frame layout is first drawn horizontally and then rotated vertically.

In my case, I used an ordinary seekBar and just flipped out the layout.

seekbark_layout.xml - my layout that containts seekbar which we need to make vertical.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rootView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<SeekBar
    android:id="@+id/seekBar"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:layout_alignParentBottom="true"/>

</RelativeLayout>

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.vgfit.seekbarexample.MainActivity">

<View
    android:id="@+id/headerView"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:background="@color/colorAccent"/>

<View
    android:id="@+id/bottomView"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_alignParentBottom="true"
    android:background="@color/colorAccent"/>

<include
    layout="@layout/seekbar_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@id/bottomView"
    android:layout_below="@id/headerView"/>

 </RelativeLayout>

And in MainActivity I rotate seekbar_layout:

import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import android.widget.RelativeLayout
import kotlinx.android.synthetic.main.seekbar_layout.*


class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    rootView.post {
        val w = rootView.width
        val h = rootView.height

        rootView.rotation = 270.0f
        rootView.translationX = ((w - h) / 2).toFloat()
        rootView.translationY = ((h - w) / 2).toFloat()

        val lp = rootView.layoutParams as RelativeLayout.LayoutParams
        lp.height = w
        lp.width = h
        rootView.requestLayout()
    }
}
}

As a result we have necessary vertical seekbar:

By using RotateLayout, having vertical SeekBar is a breeze. Just wrap that horrible SeekBar into it and Bob is your uncle:

<com.github.rongi.rotate_layout.layout.RotateLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:angle="-90"
    >

        <androidx.appcompat.widget.AppCompatSeekBar
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
        />
