Android 添加菜单

res下添加Menu文件夹,添加main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">    <item android:id="@+id/add_item" android:title="Add"/>    <item android:id="@+id/remove_item" android:title="Remove"/></menu>

重写方法

@Overridepublic boolean onCreateOptionsMenu(Menu menu) {    getMenuInflater().inflate(R.menu.main, menu);    return true;}

@Overridepublic boolean onOptionsItemSelected(MenuItem item) {    switch (item.getItemId()) {        case R.id.add_item:            Toast.makeText(getApplicationContext(), "You clickde Add", Toast.LENGTH_SHORT).show();            break;        case R.id.remove_item:            Toast.makeText(getApplicationContext(), "You clickde Remove", Toast.LENGTH_SHORT).show();            break;        default:    }    return true;}

运行程序可在标题栏看到如下
