I meant something like the following:
In progress_horizontal replace ClipDrawable with id 'progress' by a
ScaleDrawable:
<item android:id="@+id/progress">
<scale android:scaleGravity="left" android:scaleWidth="100%" >
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ffffd300"
android:centerColor="#ffffb600"
android:centerY="0.75"
android:endColor="#ffffcb00"
android:angle="270"
/>
</shape>
</scale>
</item>
>From Java you can access the GradientDrawable inside the ScaleDrawable
as follows:
ProgressBar progBar;
ScaleDrawable sd = (ScaleDrawable) ((LayerDrawable)
progBar.getProgressDrawable()).findDrawableByLayerId(R.id.progress);
GradientDrawable gd = (GradientDrawable) sd.getDrawable();
gd.setColor(Color.BLUE);
=============================================================
Setting own ProgressDrawable from xml works. You only need to tell
Android that you want to use your own drawable by specifying your own
drawable as android:progressDrawable:
<ProgressBar
android:id="@+id/ProgressBar01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="?android:attr/progressBarStyleHorizontal"
android:progressDrawable="@drawable/progress_horizontal"
/>
