如何将按钮更改为android eclipse中的菜单

Question

我搜索了高低搜索到一个简单的方法来将按钮变成菜单（任何菜单样式）我目前在我的应用程序中有按钮，我想将它们变成的菜单（在右上角的3点）为更简单的用户界面

我想下面出现在菜单： bCheckOnline bSettings bLogout1

如果这是很多比我想象的更复杂请与我联系，我将支付某人修改我的代码。 （但是，任何帮助表示赞赏！）

我已经包含下面我RES /布局/ activity_main.xml中：

在先进的感谢伙计们！

Answer 1

您需要扩展ActionBarActivity insted的Activity。

然后进行功能onCreateOptionsMenu

@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; 
} 

然后让onOptionsItemSelected

@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. 
    int id = item.getItemId(); 
    if (id == R.id.action_settings) { 

     // Do something when Settings button is clicked. 

     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 

和你资源的开发文件夹都必须有main.xml中的东西菜单文件夹一样

<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.test.MainActivity" > 

    <item 
     android:id="@+id/action_settings" 
     android:orderInCategory="100" 
     android:title="@string/action_settings" 
     app:showAsAction="never"/> 

</menu> 

你可以玩上面的代码来试验它并修改相同的t o得到你想要的结果。我希望这些信息是有帮助的。阅读更多关于它here.
