使用Touch事件监听器移动RelativeLayout可以使布局在移动时摆动

Question

I am trying to move a RelativeLayout view around using theTouch Listener.

The problem is that While the Layout is indeed moving it is wiggeling fast between to positions. This is the full touch listener

    protected void touch(){
    Mover manmove = new Mover();

   Wall.setOnTouchListener(new View.OnTouchListener() {


       @Override
       public boolean onTouch(View view, MotionEvent motionEvent) {
           final int action = motionEvent.getAction();
           if(!isZooming()){

           switch (action & MotionEvent.ACTION_MASK) {
               //If The Screen is Tapped
               case (MotionEvent.ACTION_UP):
               case (MotionEvent.ACTION_DOWN):
                   //Setting the initial Touch point
                   setTouchDownX(motionEvent.getX());
                   setTouchDownY(motionEvent.getY());

                   break;

               case (MotionEvent.ACTION_MOVE):


                       float my = getaY() + (motionEvent.getY() - getTouchDownY());
                       console.log(my);

                      // manmove.moveY(my);



                   break;

           }

           }


           return true;
       }

    });

 }

I have created a Console class that logs info to my console.

the manmove.moveY(my)code is at the bottom.

if I (as done above) comment out the manmove.moveY(), as in dont run the method. Console.log outputs the following (Which are the desired coordinates).

I/ViewRootImpl: ViewRoot's Touch Event : ACTION_DOWN
I/Console(Float):: 0.0
I/Console(Float):: 0.0
I/Console(Float):: -9.876221
I/Console(Float):: -22.249512
I/Console(Float):: -39.085938
I/Console(Float):: -58.50659
I/Console(Float):: -82.34204
I/Console(Float):: -101.75574
I/Console(Float):: -122.02234
I/Console(Float):: -141.76233
I/Console(Float):: -159.39001
I/Console(Float):: -174.78223
I/Console(Float):: -189.00647
I/Console(Float):: -202.30786
I/Console(Float):: -215.42957
I/Console(Float):: -229.95398
I/Console(Float):: -244.98132
I/Console(Float):: -258.14148
I/Console(Float):: -272.5271

As you can see they are sequential, so the move should be smooth. but if I run manmove.moveY(my)

                       else{
                       //Allow Scrolling on FullView
                       float my = getaY() + (motionEvent.getY() - getTouchDownY());
                       console.log(my);

                       manmove.moveY(my);


                   }

I get this Output;

I/ViewRootImpl: ViewRoot's Touch Event : ACTION_DOWN
I/Console(Float):: 0.0
I/Console(Float):: 0.0
I/Console(Float):: 0.0
I/Console(Float):: -7.222168
I/Console(Float):: -86.498535
I/Console(Float):: -60.04187
I/Console(Float):: -125.71619
I/Console(Float):: -92.756226
I/Console(Float):: -152.55365
I/Console(Float):: -113.45459
I/Console(Float):: -178.72412
I/Console(Float):: -140.0473
I/Console(Float):: -206.31036
I/Console(Float):: -170.90485
I/Console(Float):: -222.82135
I/Console(Float):: -188.71191
I/Console(Float):: -234.86389

As you can see the output isnt in order. As if there are two different events happening. Why am I getting this result by just running the below method

(Wall by the way is a RelativeLayout)

Here's the moveY(my) method

public class Mover extends Brain {
public Mover(){

}

public void moveX(float val){


   Wall.setX(val);

}
public void moveY(float val){

    Wall.setY(val);

}

Okay guys forget about it I solved it.

All I had to do is setaY(my) to update the new position.

        float my = getaY() + (motionEvent.getY() - getTouchDownY());
                       console.log(my);

                       manmove.moveY(my);
                       setaX(my);
