使用菜单

1.在menu目录下定义speed.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:id="@+id/start" android:title="start!" android:orderInCategory="1"></item>
<item android:id="@+id/stop" android:title="stop!" android:orderInCategory="4"/>
<item android:id="@+id/accel" android:title="Vroom! Accelerate!" android:orderInCategory="2"/>
<item android:id="@+id/decel" android:title="Decelerate!" android:orderInCategory="3"/>
</menu>

2.在action中重写onCreateOptionsMenu方法

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.speed, menu);
return true;
}
