Overflower Menu icon display implementation in Menu [rewrite the onMenuOpened method and use the reflection principle]

1/** 2 * display overflower Menu icon 3 */4 @ Override 5 public boolean onMenuOpened (int featureId, menu Menu) {6 if (featureId = Window. FEATURE_ACTION_BAR & menu! = Null) {7 if (menu. getClass (). getSimpleName (). equals ("MenuBuilder") {8 try {9 Method m = menu. getClass (). getDeclaredMethod ("setOptionalIconsVisible", Boolean. TYPE); 10 m. setAccessible (true); 11 m. invoke (menu, true); 12} catch (Exception e) {13} 14} 15} 16 return super. onMenuOpened (featureId, menu); 17}

1/** 2 * menu click the listening event of the operation. 3 */4 @ Override 5 public boolean onOptionsItemSelected (MenuItem item) {6 switch (item. getItemId () {7 case android. r. id. home: 8 // finish (); 9 super. onBackPressed (); 10 break; 11 case R. id. action_add: 12 Toast. makeText (this, "add", Toast. LENGTH_SHORT ). show (); 13 break; 14} 15 return super. onOptionsItemSelected (item); 16}
