Display OptionsMenu in FragmentActivity

I tried to display options menu in FragmentActivity, and run on Android 5, but the option menu doesn't shown!

My case is:

Min Sdk Version: API 16: Android 4.1 (Jelly Bean)

Target Sdk Version: API 23; Android 6.0 (Marshmallow)

Compile Sdk Version: API 23: Android 6.0 (Marshmallow)

Build Tools Version: 23.0.1

values/styles.xml

menu/activity_main.xml

xmlns:app="http://schemas.android.com/apk/res-auto">

        android:id="@+id/option1"

android:orderInCategory="100"

app:showAsAction="always"

android:title="Option 1"/>

        android:id="@+id/option2"

android:orderInCategory="100"

android:title="Option 2"/>

        android:id="@+id/option3"

android:orderInCategory="100"

android:title="Option 3"/>

MainActivity.java

package com.blogspot.android_er.testfragmentactivity;



import android.os.Bundle;

import android.support.v4.app.FragmentActivity;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.Toast;



public class MainActivity extends FragmentActivity {



@Override

protected 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 super.onCreateOptionsMenu(menu);

}



@Override

public boolean onOptionsItemSelected(MenuItem item) {

switch(item.getItemId()){

case R.id.option1:

Toast.makeText(MainActivity.this, "Option 1", Toast.LENGTH_LONG).show();

return true;

case R.id.option2:

Toast.makeText(MainActivity.this, "Option 2", Toast.LENGTH_LONG).show();

return true;

case R.id.option3:

Toast.makeText(MainActivity.this, "Option 3", Toast.LENGTH_LONG).show();

return true;

}

return super.onOptionsItemSelected(item);

}

}

To fix it:

(approach 1)

Edit MainActivity.java, extends ActionBarActivity (deprecated) or AppCompatActivity, instead of FragmentActivity.

Refer to the document of FragmentActivity, If you want to implement an activity that includes an action bar, you should instead use the ActionBarActivity class, which is a subclass of this one, so allows you to use Fragment APIs on API level 7 and higher.

And, ActionBarActivity is deprecated, so you should use AppCompatActivity instead.

(approach 2)

Alternatively, edit values/styles.xml, set parent of
