Example of Action Menu with grouped CheckBox.

Action Menu with grouped CheckBox


Create /res/menu/activity_main.xml to define action menu.
<menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/menu_settings" android:title="@string/menu_settings" android:orderInCategory="100" android:showAsAction="never" /> <group android:checkableBehavior="single"> <item android:id="@+id/selecta" android:title="Selection A" android:checked="true"/> <item android:id="@+id/selectb" android:title="Selection B" /> <item android:id="@+id/selectc" android:title="Selection C" /> </group> </menu>


The checked status will not be updated automatically. We can change it in onOptionsItemSelected() callback method.
package com.example.androidactionbar; import android.os.Bundle; import android.app.Activity; import android.view.Menu; import android.view.MenuItem; import android.widget.Toast; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.selecta: item.setChecked(true); Toast.makeText(getApplicationContext(), "A Selected", Toast.LENGTH_LONG).show(); return true; case R.id.selectb: item.setChecked(true); Toast.makeText(getApplicationContext(), "B Selected", Toast.LENGTH_LONG).show(); return true; case R.id.selectc: item.setChecked(true); Toast.makeText(getApplicationContext(), "C Selected", Toast.LENGTH_LONG).show(); return true; default: return super.onOptionsItemSelected(item); } } }
