我无法获得触摸坐标

Question

我有一个大问题。我一直试图让触摸坐标持续数小时。但它没有奏效。我的代码是：

@Override
public boolean onTouchEvent(MotionEvent event)
{
    if (event. getAction ()==MotionEvent.ACTION_DOWN){
            touchx = event . getX   ();
        touchy= event . getY();


    }
    }
    return true;
    }

@Override
public void render()
{   
    touch=Gdx.input.isTouched();
    Gdx.gl.glClearColor(1, 1, 1, 1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
    batch.begin();
    if(touchx>2){
    batch.draw(texture, Gdx.graphics.getWidth() / 4, 0, 
               Gdx.graphics.getWidth() / 2, Gdx.graphics.getWidth() / 2);

               }
               batch.end();

}

它不起作用。问题在哪里？

@Override 
    public boolean dispatchTouchEvent(MotionEvent event){
        int i=0;
        i++;

        System.out.println("-.-------------------X:"+event.getX()+"Y: "+event.getY());
        return true;
 }
