Question

我搜索了高低，找到一种简单的方法将按钮变成菜单（任何菜单样式）我目前在我的应用程序中有按钮，我想将它们变成菜单（即右边的3个点）角落）以获得更简单的用户界面

我希望以下内容出现在菜单中： bCheckOnline bSettings bLogout1

如果这比我想象的要复杂得多，请与我联系，我会付钱给别人修改我的代码。（但是，任何帮助都表示赞赏！）

我在下面包含了我的res / layout / activity_main.xml：

感谢先进的人！

您需要扩展活动的ActionBarActivity内容。

然后为onCreateOptionsMenu

创建一个函数

@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;
}

然后制作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);
}

在你的Resourses文件夹中必须有一个main.xml的菜单文件夹，如

<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>

您可以使用上面的代码进行试验并修改它以获得所需的结果。我希望这些信息有用。详细了解here.
