How to change android slidingdrawer handle button position

In defau开发者_JAVA百科lt handle button in android SlidingDrawer in the centre of the drawer. Is it possible to change that position to left or right..? If it possible how can I do that, android:gravity="left" is not work in the button.

Put your handle in a RelativeLayout, and set android:layout_alignParentRight="true" on the handle.

For example like this:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

    <TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />

    <SlidingDrawer android:id="@+id/drawer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:handle="@+id/handle" 
        android:content="@+id/content">

        <RelativeLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" 
            android:id="@+id/handle">
            <ImageView android:src="@drawable/icon"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true" />
        </RelativeLayout>

        <LinearLayout 
            android:gravity="center" 
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:background="#aaaa00" android:id="@+id/content">
            <ImageView android:src="@drawable/icon"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="center">
            </ImageView>
        </LinearLayout>

    </SlidingDrawer>

</FrameLayout>

The problem I had with HenrikS answer was that in my case I had some views behind the relative layout and when I tried to click them I realized that the relative layout was intercepting those clicks because the width was set to fill_parent.

To workaround this I modified the layout of the handler view (the ImageView) in my case to the left, hope it is helpful.

public class CustomSlidingDrawer extends SlidingDrawer {

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

public CustomSlidingDrawer(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
    super.onLayout(changed, l, t, r, b);

    final int height = b - t;

    ImageView handle = (ImageView) getHandle();
    int childLeft = 0;
    int childWidth = handle.getWidth();
    int topOffset = 0;
    int bottomOffest = 0;
    int childHeight = handle.getHeight();

    int childTop = this.isOpened()?topOffset:height - childHeight + bottomOffest;

    handle.layout(childLeft, childTop , childLeft + childWidth, childTop+childHeight);
}
}

The idea is simple: set the handle's padding to the correct value depending on the alignment you want.

In the example below, I derive a class from SlidingDrawer and override onLayout as follows. My sliding drawer is at the bottom of the screen, and I want the handle to be left-aligned rather than center-aligned.

public class ToolDrawer extends SlidingDrawer {
    private int m_handleWidth = 0;  // original handle width

    public boolean onTouchEvent(MotionEvent event) {
        float x = event.getX();
        if (x <= m_handleWidth) {
            return super.onTouchEvent(event);
        }
        return false;
    }

    protected void onLayout (boolean changed, int left, int top, int right, int bottom) {
        super.onLayout(changed, left, top, right, bottom);

        if (changed) {
            ImageView iv = (ImageView) getHandle();
            iv.setPadding(0, 0, getWidth() - iv.getWidth(), 0);
            if (m_handleWidth == 0) {
                m_handleWidth = iv.getWidth();
            }
        }
    }
}

It's as simple as that.

I tried android:paddingBottom="300dp" for the ImageView and it works fine, also with left, right and top. But you have to set the padding from the middle-position, so bottom="300dp" means the handle move up 300 from the middle

A simpler solution for left-aligned handle:

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
    super.onLayout(changed, l, t, r, b);
    final View handle = getHandle();
    handle.layout(0, handle.getTop(), handle.getWidth(), handle.getBottom());
}

I have researched this problem for 2 days and I realized that you need to use another library. Because, when you use RelativeLayout or LinearLayout, you're just get fill_parent screen and of course it will be affected by touching ( although you don't touch on icon ).

So, I use SlidingTray from Sileria library ( ver 3.5 ) http://aniqroid.sileria.com/doc/api/

Then like this

I found the solution for garibay You just need to set android:clickable="true" on content layout of sliding drawer.
