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

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

@Override public 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

点击可以得到如下2个按钮
