推荐答案

包括安卓configChanges =定向在 AndroidManifest.xml中到活动显示窗口。这样做会告诉机器人，你会自己处理方向变化，最终它不会破坏你的活动，保持显示的窗口。

include android:configChanges="orientation" in your AndroidManifest.xml to the activity displaying window. Doing this tells android that you are going to handle orientation change yourself and eventually it will not destroy your activity and keeping the window displayed.

如果你没有不同的布局为纵向和横向模式这项技术是不错的。但是，如果你这样做，你还可以通过检测方向模式下面执行自定义布局实现：

This technique is good if you dont have different layouts for portrait and landscape mode. However, if you do, you may still perform custom layout implementation by detecting the orientation mode as below:

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

    if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
        Log.i("orientation", "Orientation changed to: Landscape");
    else
        Log.i("orientation", "Orientation changed to: Portrait");
}

为preVIEW，下载并安装此示例应用。
