使用定向监听器在不同的定向上执行不同的任务。

@Override
public void onConfigurationChanged(Configuration myConfig) 
{
    super.onConfigurationChanged(myConfig);
    int orient = getResources().getConfiguration().orientation; 
    switch(orient) 
    {
       case Configuration.ORIENTATION_LANDSCAPE:
          setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                    break;
       case Configuration.ORIENTATION_PORTRAIT:
          setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                    break;
       default:
          setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
    }
}

要在Android清单中进行的更改包括：

android:configChanges="keyboardHidden|orientation" 

要在活动中添加的内容包括：

public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
    }
}

在该活动集中，配置更改如下

 android:configChanges="orientation|screenSize|keyboardHidden"

我所做的。。。

在清单的活动部分中，添加了：

android:configChanges="keyboardHidden|orientation"

在活动代码中，实现：

//used in onCreate() and onConfigurationChanged() to set up the UI elements
public void InitializeUI()
{
    //get views from ID's
    this.textViewHeaderMainMessage = (TextView) this.findViewById(R.id.TextViewHeaderMainMessage);

    //etc... hook up click listeners, whatever you need from the Views
}

//Called when the activity is first created.
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    InitializeUI();
}

//this is called when the screen rotates.
// (onCreate is no longer called when screen rotates due to manifest, see: android:configChanges)
@Override
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    setContentView(R.layout.main);

    InitializeUI();
}

修复AndroidManifest.xml中的屏幕方向（横向或纵向）

android:screenOrientation=“纵向”或android:scheenOrientation=“横向”

为此，不会调用onResume（）方法。

将此行添加到清单中：-

android:configChanges="orientation|keyboard|keyboardHidden|screenSize|screenLayout|uiMode"

将此代码段添加到活动：-

@Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
