Android(安卓)Service中判断系统全屏

1. 空layout

<?xml version="1.0" encoding="utf-8"?>

2. java中定义layout变量

mFullScreenCheckView = (LinearLayout) inflater.inflate(R.layout.full_screen_layout, null);

3. 设置Global Layout Listener

private void createFullScreenCheckView() {SecLog.e(TAG, "createFloatView");WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();layoutParams.type = LayoutParams.TYPE_PHONE;layoutParams.format = PixelFormat.TRANSPARENT;layoutParams.flags = LayoutParams.FLAG_NOT_FOCUSABLE;layoutParams.gravity = Gravity.LEFT | Gravity.TOP;layoutParams.width = 1;layoutParams.height = LayoutParams.MATCH_PARENT;mFullScreenCheckView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener(){@SuppressLint("NewApi")@Overridepublic void onGlobalLayout() {DisplayMetrics dm = new DisplayMetrics();mWindowManager.getDefaultDisplay().getMetrics(dm);int viewHeight = mFullScreenCheckView.getHeight();if(viewHeight == dm.widthPixels || viewHeight == dm.heightPixels){bIsFullScreen = true;}else{bIsFullScreen = false;}}});mWindowManager.addView(mFullScreenCheckView, layoutParams);}
