浮动窗体

废话不多说直接上代码：首先判断是不是显示在桌面上，是显示在桌面上，浮动窗没有移除，则更新他在内存使用百分比，

// 创建一个浮动窗体

WindowManager windowManager = getWindowManager(context);
       if (smallWindow == null) {
           smallWindow = new FloatWindowSmallView(context);
           if (smallWindowParams == null) {
               smallWindowParams = new LayoutParams();
               smallWindowParams.type = LayoutParams.TYPE_PHONE;
               smallWindowParams.format = PixelFormat.RGBA_8888;
               smallWindowParams.flags = LayoutParams.FLAG_NOT_TOUCH_MODAL
                       | LayoutParams.FLAG_NOT_FOCUSABLE;
               smallWindowParams.gravity = Gravity.LEFT | Gravity.TOP;
               smallWindowParams.width = FloatWindowSmallView.viewWidth;
               smallWindowParams.height = FloatWindowSmallView.viewHeight;
               smallWindowParams.x = ScreenUtils.getScreenW();
               smallWindowParams.y = ScreenUtils.getScreenH() / 2;
           }
           smallWindow.setParams(smallWindowParams);
           windowManager.addView(smallWindow, smallWindowParams);
       }

// 创建好了一个浮动窗体，那个浮动窗体总要移动的，所以要重写onTouchEvent方法。

switch (event.getAction()) {
       case MotionEvent.ACTION_DOWN:
           // 手指按下时记录必要数据,纵坐标的值都需要减去状态栏高度
           xInView = event.getX();
           yInView = event.getY();
           xDownInScreen = event.getRawX();
           yDownInScreen = event.getRawY() - ScreenUtils.getStatusBarHeight();
           xInScreen = event.getRawX();
           yInScreen = event.getRawY() - ScreenUtils.getStatusBarHeight();
           break;
       case MotionEvent.ACTION_MOVE:
           xInScreen = event.getRawX();
           yInScreen = event.getRawY() - ScreenUtils.getStatusBarHeight();
           // 手指移动的时候更新小悬浮窗的位置
           updateViewPosition();

           //移动小悬浮框时，显示删除框
           if(!MyWindowManager.isDeleteWindowShowing()){
               MyWindowManager.createDeleteWindow(getContext());
           }

           if(isInDeleteArea(xInScreen, yInScreen)){
               MyWindowManager.setDeleteTextColor(Color.BLACK);
           }else{
               MyWindowManager.setDeleteTextColor(Color.GRAY);
           }
           break;
       case MotionEvent.ACTION_UP:
           // 如果手指离开屏幕时，xDownInScreen和xInScreen相等，且yDownInScreen和yInScreen相等，则视为触发了单击事件。
           if (xDownInScreen == xInScreen && yDownInScreen == yInScreen) {
               openBigWindow();
           }

           //移除删除框
           MyWindowManager.removeDeleteWindow(getContext());
           //用户将小图标拖动到了删除框，则移除所有悬浮窗，并停止Service
           if(isInDeleteArea(xInScreen, yInScreen)){
               MyWindowManager.removeBigWindow(getContext());
               MyWindowManager.removeSmallWindow(getContext());

               Intent intent = new Intent(getContext(), FloatWindowService.class);
               getContext().stopService(intent);
           }

           break;
       default:
           break;
       }
       return true;
