您可以为它制作自定义ontouchlistener并相应地设置x和y位置。

以下是一个示例。

来自它的MAIN代码部分（如果链接过期）：

public class MultiTouchListener implements OnTouchListener
{

private float mPrevX;
private float mPrevY;

public MainActivity mainActivity;
public MultiTouchListener(MainActivity mainActivity1) {
    mainActivity = mainActivity1;
}

@Override
public boolean onTouch(View view, MotionEvent event) {
    float currX,currY;
    int action = event.getAction();
    switch (action ) {
        case MotionEvent.ACTION_DOWN: {

            mPrevX = event.getX();
            mPrevY = event.getY();
            break;
        }

        case MotionEvent.ACTION_MOVE:
        {

                currX = event.getRawX();
                currY = event.getRawY();


                MarginLayoutParams marginParams = new MarginLayoutParams(view.getLayoutParams());   
                marginParams.setMargins((int)(currX - mPrevX), (int)(currY - mPrevY),0, 0);
                RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
                view.setLayoutParams(layoutParams); 


            break;
        }



        case MotionEvent.ACTION_CANCEL:
            break;

        case MotionEvent.ACTION_UP:

            break;
    }

    return true;
}

}

现在在您的Main活动中，在您的视图上设置OnTouchListener ...这是您的imageButton或imageView;

MultiTouchListener touchListener=new MultiTouchListener(this);
onButton.setOnTouchListener(touchListener);

希望，这有帮助！。
