overlay two images in android to set an imageview

by

You can skip the complex Canvas manipulation and do this entirely with Drawables, using LayerDrawable. You have one of two choices: You can either define it in XML then simply set the image, or you can configure a LayerDrawable dynamically in code.

Solution #1 (via XML):

Create a new Drawable XML file, let’s call it layer.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/t" />
    <item android:drawable="@drawable/tt" />
</layer-list>

Now set the image using that Drawable:

testimage.setImageDrawable(getResources().getDrawable(R.layout.layer));

Solution #2 (dynamic):

Resources r = getResources();
Drawable[] layers = new Drawable[2];
layers[0] = r.getDrawable(R.drawable.t);
layers[1] = r.getDrawable(R.drawable.tt);
LayerDrawable layerDrawable = new LayerDrawable(layers);
testimage.setImageDrawable(layerDrawable);

(I haven’t tested this code so there may be a mistake, but this general outline should work.)
