Answer 1

Instead of this you may be use any layout and apply your xml as selector and for that layout you apply dynamic backgrounds via GradientDrawable.

For example , main.xml

Then your xml ,shapes.xml

And write following code in your activity.

    RelativeLayout  mainLayout= (RelativeLayout ) findViewById(R.id.mainLayout);
    GradientDrawable gd = new GradientDrawable();
    gd.setColor(Color.RED);
    gd.setCornerRadius(10);
    gd.setStroke(2, Color.WHITE);
    mainLayout.setBackgroundDrawable(gd);

For more GradientDrawable use the link http://developer.android.com/reference/android/graphics/drawable/GradientDrawable.html

Hopes this will help you.
