效果如下：

?

實現方案：

1、ChangeOrientationService.java

/*** @描述 強制旋轉屏幕服務* @作者 tll* @時間 2018/1/5*/public class ChangeOrientationService extends Service {private final IBinder mBinder = new LocalBinder();@Nullable@Overridepublic IBinder onBind(Intent intent) {return mBinder;}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {WindowManager mWindow = (WindowManager) getSystemService(WINDOW_SERVICE);CustomLayout mLayout = new CustomLayout(intent.getIntExtra("orientation", 0));mWindow.addView(new View(this), mLayout);stopSelf();return START_NOT_STICKY;}public class LocalBinder extends Binder {public LocalBinder() {super();}}public class CustomLayout extends android.view.WindowManager.LayoutParams {public CustomLayout(int paramInt) {// TYPE_SYSTEOM_OVERLAY:the layer that is on the top of the window(位于窗口頂部的層)super(0, 0, TYPE_SYSTEM_OVERLAY, FLAG_FULLSCREEN | FLAG_NOT_FOCUSABLE, PixelFormat.RGBX_8888);// push object to the top of its container, not changing its size.(將對象推到容器的頂部，而不是改變其大小。)this.gravity = Gravity.TOP;// set the screenOrientation as desired(按需要設置屏幕方向)this.screenOrientation = paramInt;}} }

2.AndroidManifest.xml

<serviceandroid:name=".services.ChangeOrientationService"android:permission="android.permission.WRITE_SETTINGS"/>

?3.fragment里面使用

/*** 請求用戶給予懸浮窗的權限*/public boolean askForOverlayPermission() {if (!MyWindowManager.checkPermission()) {//檢測懸浮窗權限MyWindowManager.applyPermission(getActivity());//跳轉到懸浮窗權限界面return false;} else {//開啟橫屏服務Intent mIntent = new Intent(getActivity(), ChangeOrientationService.class);mIntent.putExtra("orientation", ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);getActivity().startService(mIntent);return true;}}
