  4. Enter the menu name and click on Ok.
  5. In the context_menu.xml, add the following code
  6. <?xml version="1.0" encoding="utf-8"?>
    <menu
    	xmlns:android="http://schemas.android.com/apk/res/android">
    	<item android:title="Search" android:id="@+id/search" />
    	<item android:title="About" android:id="@+id/about" />
    </menu>


  7. Next step is to create a list view and register it for context menu.
  8. String fruitlist[] = {
      "apple",
      "banana",
      "orange",
      "cherry"
    };
    ListView listView = (ListView) findViewById(R.id.listview);
    ArrayAdapter < String > adapter = new ArrayAdapter < String > (this, R.layout.support_simple_spinner_dropdown_item, fruitlist);
    listView.setAdapter(adapter);
    registerForContextMenu(listView);


  9. Override onCreateContextMenu and onContextItemSelected
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
  super.onCreateContextMenu(menu, v, menuInfo);
  MenuInflater inflater = getMenuInflater();
  inflater.inflate(R.menu.context_menu, menu);
}
@Override
public boolean onContextItemSelected(@NonNull MenuItem item) {
  AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item;
  switch (item.getItemId()) {
  case R.id.search:
    Toast.makeText(EditTextDemo.this, "Search Clicked", Toast.LENGTH_LONG).show();
    return true;
  case R.id.about:
    Toast.makeText(EditTextDemo.this, "About Clicked", Toast.LENGTH_LONG).show();
    return true;
  default:
    return super.onContextItemSelected(item);
  }
}
