@Override public void onWindowFocusChanged(boolean hasFocus) { if(hasFocus){ //code to be executed when window has gained focus } else { //code to be executed when window has lost focus } }
@Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); if(hasFocus) { //code to be executed when window has gained focus } }In this example, the onWindowFocusChanged method is also overridden, but it first calls the super method before executing any additional code. The android.app package library contains classes for creating and managing activities, including the Activity class.
