java使用motionevents模拟鼠标单击

Question

我试图模拟当应用程序中的鼠标垫被按下而未移动时的鼠标点击

  if(isConnected && out!=null){
                switch(event.getAction()){
                    case MotionEvent.ACTION_DOWN:
                        //save X and Y positions when user touches the TextView
                        initX =event.getX();
                        initY =event.getY();
                        mouseMoved=false;
                        break;
                    case MotionEvent.ACTION_MOVE:
                        disX = event.getX()- initX; //Mouse movement in x direction
                        disY = event.getY()- initY; //Mouse movement in y direction
                        /*set init to new position so that continuous mouse movement
                        is captured*/
                        initX = event.getX();
                        initY = event.getY();
                        if(disX !=0|| disY !=0){
                            out.println(disX +","+ disY); //send mouse movement to server
                        }
                        mouseMoved=true;
                        break;
                    case MotionEvent.ACTION_UP:
                        //consider a tap only if usr did not move mouse after ACTION_DOWN
                        if(!mouseMoved){
                               out.println(Constants.MOUSE_LEFT_CLICK);
                        }
                }
            }
            return true;
        }
    });
}

我试过这个，但我不明白为什么它不起作用。每次我点击鼠标垫，鼠标就会移动。我怎样才能解决这个问题

Answer 1

用if-else试一下，先按一下，然后在else中移动

Answer 2

我通过设置一个余量来解决我的问题

int max = 2 
int min = -2
case MotionEvent.ACTION_UP:
                        //consider a tap only if usr did not move mouse after ACTION_DOWN
                        if(disX <= max && disX >= min && disY <= max && disY >= min){
                            out.println(Constants.MOUSE_LEFT_CLICK);
                            mouseMoved=false;
                            break;
                        }
                }
            }
            return true;
        }
