效果如下：
实现方案：
1、ChangeOrientationService.java
/** * @描述 强制旋转屏幕服务 * @作者 tll * @时间 2018/1/5 */ public class ChangeOrientationService extends Service { private final IBinder mBinder = new LocalBinder(); @Nullable @Override public IBinder onBind(Intent intent) { return mBinder; } @Override public 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(位于窗口顶部的层) 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.(将对象推到容器的顶部，而不是改变其大小。) this.gravity = Gravity.TOP; // set the screenOrientation as desired(按需要设置屏幕方向) this.screenOrientation = paramInt; } } }
2.AndroidManifest.xml
<service
android:name=".services.ChangeOrientationService"
android:permission="android.permission.WRITE_SETTINGS"/>
3.fragment里面使用
/**
* 请求用户给予悬浮窗的权限
*/
public boolean askForOverlayPermission() {
if (!MyWindowManager.checkPermission()) {//检测悬浮窗权限
MyWindowManager.applyPermission(getActivity());//跳转到悬浮窗权限界面
return false;
} else {//开启横屏服务
Intent mIntent = new Intent(getActivity(), ChangeOrientationService.class);
mIntent.putExtra("orientation", ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
getActivity().startService(mIntent);
return true;
}
}
4.悬浮窗相关的类
public class MyWindowManager {
private static final String TAG = "MyWindowManager";
/**
* 小悬浮窗View的参数
*/
private WindowManager.LayoutParams smallWindowParams;
/**
* 用于控制在屏幕上添加或移除悬浮窗

* @return WindowManager的实例，用于控制在屏幕上添加或移除悬浮窗。
