Android menu creation and implementation

To create a menu resource, create an yourmenu.xml file inside your project's res/menu/ directory


yourmenu.xml 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_next"
       android:icon="@drawable/icon_next" 
          android:title="Next" />
    <item android:id="@+id/menu_back"
       android:icon="@drawable/icon_back"
          android:title="Back" />
</menu>

Creation 

@Override
public boolean onCreateOptionsMenu(Menu menu) {
 MenuInflater inflater = getMenuInflater();
 inflater.inflate(R.menu.yourmenu, menu);
 return true;
}

If menu item selected..

@Override
public boolean onOptionsItemSelected(MenuItem item) {
 
 switch (item.getItemId()) {
   case R.id.menu_next:
   //your code here..
   return true;
   default:
   return super.onOptionsItemSelected(item);
 }
}
