How can I change the style of a ProgressBar to small?

I have some difficulties fin开发者_如何学Pythonding the correct way to specify that a progress bar should have the small indefinite style.

I would be glad if somebody could provide an example for me and others that do a quick search for this information.

The solution is to change the style to

<ProgressBar
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   style="?android:attr/progressBarStyleSmall" />

One more way to do it is

style="@android:style/Widget.ProgressBar.Small" 

Ex_

<ProgressBar
 android:id="@+id/progress_bar"
 style="@android:style/Widget.ProgressBar.Small"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:padding="7dip"
 arandroid:visibility="visible" />

Here is how to do it programmatically:

ProgressBar progress = new ProgressBar(ctx, null, android.R.attr.progressBarStyleSmall);

This may be of use:

style="?android:attr/android:progressBarStyleSmall"

You can change the size of progress bar easily by scaleX and scaleY property, like this:

<ProgressBar
        android:id="@+id/progressBar"
        android:scaleX="0.5"
        android:scaleY="0.5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

Here,

scaleX: To change the width, so 0.5 will reduce the width to the half of the actual width

scaleY: To change the height, so 0.5 will reduce the height to the half of actual height

 <ProgressBar
        android:id="@+id/progressBar1"
        android:layout_width="wrap_content
        style="?android:attr/progressBarStyleSmallTitle"
        android:layout_height="wrap_content" />

<!--changing of color,small size spinner-->
    <style name="progressColor" parent="@android:style/Widget.ProgressBar.Small">
        <item name="colorControlActivated">@color/colorPrimary</item>
    </style>

you can achieve color and small size spinner by using above style in spinner

<ProgressBar
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            style="@style/progressColor"
            android:layout_gravity="center" />

According to the answer of @Rupesh Yadav, you can see a structure of the style @android:style/Widget.ProgressBar.Small:

<style name="Widget.ProgressBar.Small">
    <item name="indeterminateDrawable">@drawable/progress_small_white</item>
    <item name="minWidth">16dip</item>
    <item name="maxWidth">16dip</item>
    <item name="minHeight">16dip</item>
    <item name="maxHeight">16dip</item>
</style>

I can confirm that setting min and max sizes solves the problem. Setting width and height explicitly doesn't change the size of the ProgressBar. So you can make your own style.
