Set size for individual layer of layer-list from Java

Question

I am showing 2 images in a layer-list this way. Following is layered_map.xml in drawable

    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
           <item android:drawable="@drawable/bgimage" />
           <item android:id="@+id/marker"
                 android:drawable="@drawable/point"
                 android:left="660sp"
                 android:right="210sp"
                 android:top="375sp"
                 android:bottom="1125sp"
           />
    </layer-list>

Everything is fine. I get a big background image and a small layered image on top of it. Except now I would want to do what android:left, android:right, android:top, android:bottom do in xml, from Java This is what I have tried

      LayerDrawable layerDrawable = (LayerDrawable)getResources().getDrawable(R.drawable.layered_map);
      Drawable d = layerDrawable.findDrawableByLayerId(R.id.marker);
    d.setBounds(400, 300, 420, 320);
    //d.invalidateSelf();
    mImageView.setImageDrawable(layerDrawable);

But this does not work. I also read somewhere that it is not possible to set different bounds for different layers. I am also skeptical if what xml is doing in this is exactly done by setBounds. Any help will be really appreciated

Thank You

yeah You can do it using setLayerInset (int index, int l, int t, int r, int b)
