WindowManager不允许传递触摸

android-windowmanager ontouchlistener android

我用WindowManager绘制了一个覆盖图。它的宽度和高度是 WindowManager.LayoutParams.MATCH_PARENT 背景透明。

我的视图必须匹配父对象和句柄圆触摸侦听器,并将其余的触摸传递到下面的屏幕

我有两个小的 circle in left and right corner

        int LAYOUT_FLAG = Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? WindowManager.
                LayoutParams.TYPE_APPLICATION_OVERLAY : WindowManager.LayoutParams.TYPE_PHONE;

        final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.MATCH_PARENT,//changed it to full
                WindowManager.LayoutParams.MATCH_PARENT,
                LAYOUT_FLAG,

                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
                |WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
                ///| WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, this flag can make it in touchable.
                ///WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
                PixelFormat.TRANSLUCENT);

        mFloatingView = LayoutInflater.from(this).inflate(R.layout.item_circle_dragging, null);

        mFloatingView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                return false;
            }
        });
        //Add the view to the window
        mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        mWindowManager.addView(mFloatingView,params);

项目圈_拖动.xm 我

<?xml version="1.0" encoding="utf-8"?>
<customviewpracticing.CircleDraggingView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</customviewpracticing.CircleDraggingView>

环行图

@Override
public boolean onTouchEvent(MotionEvent event) {

   switch (event.getAction()) {
      case MotionEvent.ACTION_DOWN:
          if(isPointInside(event.getRawX(),event.getRawY()))
            isAllowedToDrag = true;
          Log.d(TAG, "ACTION_DOWN:getRawX= " + event.getRawX() + " getRawY= " + event.getRawY() + " getX= "
                + event.getX() + " getY= " + event.getY());
          break;
        ///return true;
      case MotionEvent.ACTION_MOVE:
          Log.d(TAG, "ACTION_MOVE:getRawX= " + event.getRawX() + " getRawY= " + event.getRawY() + " getX= "
                + event.getX() + " getY= " + event.getY());
          if(isAllowedToDrag){
            center_circle_X = event.getRawX() ;
            center_circle_Y = event.getRawY();
            }/*this.animate().x(event.getRawX()).y(event.getRawY())
                    .setDuration(50).start();*/
          break;
      case MotionEvent.ACTION_UP:
         if(isAllowedToDrag)
            isAllowedToDrag = false;
         break;
      default:
        return true;//I changed it
   }
    // Force a view to draw again
    ///postInvalidate();
    invalidate();
    return true;
}

也试过了 onTouchEvent 属于 CircleDraggingView mFloatingView视图 (根视图)。
