菜单文章的补充

各位IT好友们,真是不要意思,dck一激动忘了怎么完上面粘图片了，今天在这里吧资料补充完整:

首先,我用的模拟器是夜神模拟器;

menu的布局文件：

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.menu.MainActivity" >
<item
android:id="@+id/menu_setting"
android:orderInCategory="1"
android:icon="@drawable/bettreydck"
android:title="@string/aa"/>

<item
android:id="@+id/menu_about"
android:orderInCategory="2"
android:icon="@drawable/bettreydck"
android:title="@string/bb"/>

<item
android:id="@+id/menu_dck"
android:orderInCategory="3"
android:icon="@drawable/wifidck"
android:title="@string/cc"/>

<item
android:id="@+id/menu_cqq"
android:orderInCategory="4"
android:icon="@drawable/messagedck"
android:title="@string/dd"/>

</menu>

程序代码：

package com.example.menu;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;


public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}


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

//当菜单被点击是会触发这个方法

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.

switch (item.getItemId()) {
case R.id.menu_setting:{
Toast.makeText(MainActivity.this,"这是设置菜单",Toast.LENGTH_LONG).show();
break;
}
case R.id.menu_about:{
Toast.makeText(MainActivity.this,"这是关于菜单",Toast.LENGTH_LONG).show();
break;
}
case R.id.menu_cqq:{
Toast.makeText(MainActivity.this,"这是Cqq菜单",Toast.LENGTH_LONG).show();
break;
}
case R.id.menu_dck:{
Toast.makeText(MainActivity.this,"这是Dck菜单",Toast.LENGTH_LONG).show();
break;
}
default:
break;
}

return super.onOptionsItemSelected(item);
}
}

运行结果:
