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
*/
private WindowManager mWindowManager;
private SensorManager sm;
private Sensor sensor;
/**
* 如果WindowManager还未创建，则创建一个新的WindowManager返回。否则返回当前已创建的WindowManager。
*
* @param context 必须为应用程序的Context.
* @return WindowManager的实例，用于控制在屏幕上添加或移除悬浮窗。
*/
