Android ElevationBasic Sample

This sample demonstrates ways to move a view in the z-axis using setTranslationZ(). This method was introduced in API Level 21 (‘Lollipop’).


This sample uses two shapes, a circle and a square, and it demonstrates two alternative ways to move a view in the z-axis. The first shape, the circle, has a fixed elevation, which is defined in XML. The second view, the square, changes its elevation using setTranslationZ() when a user touches it:

shape2.setOnTouchListener(new View.OnTouchListener() {
    public boolean onTouch(View view, MotionEvent motionEvent) {
        int action = motionEvent.getActionMasked();
        /* Raise view on ACTION_DOWN and lower it on ACTION_UP. */
        switch (action) {
            case MotionEvent.ACTION_DOWN:
                Log.d(TAG, "ACTION_DOWN on view.");
            case MotionEvent.ACTION_UP:
                Log.d(TAG, "ACTION_UP on view.");
                return false;
        return true;

The elevation reverts back once the touch is removed.
