Demo Code

import android.app.Activity;
import java.lang.reflect.Method;

public class Main{

    /**/*from w  ww  .  ja v  a 2  s.  c  o m*/
     * Convert a translucent themed Activity
     * {@link android.R.attr#windowIsTranslucent} back from opaque to
     * translucent following a call to
     * {@link #convertActivityFromTranslucent(android.app.Activity)} .
     * <p>
     * Calling this allows the Activity behind this one to be seen again. Once
     * all such Activities have been redrawn
     * <p>
     * This call has no effect on non-translucent activities or on activities
     * with the {@link android.R.attr#windowIsFloating} attribute.
