我有一个相对布局,我通过onLongClick填充imageview,我的问题是我没有得到精确的坐标,每次我填充imageview它被放置在我的手指不在的点,我觉得如果我的代码:

,我错过了看下面其他应用程序的内容

此方法随机生成一个imageview。

private ImageView generateImageView()
{
    ImageView imageView = new ImageView(this);
    imageView.setImageResource(R.drawable.image_1);
    imageView.setAdjustViewBounds(true);
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT );
    imageView.setLayoutParams( params );
    this.parentLayout.addView(imageView);

    return imageView;

}

此方法将imageview移动到ontouch

中坐标提供的位置
 public boolean onTouch(View view, MotionEvent motionEvent) {

    this.absoluteClickedX = (int) motionEvent.getRawX();
    Log.d("X Coordinate", ""+this.absoluteClickedX);
    this.absoluteClickedY = (int) motionEvent.getRawY();
    Log.d("Y Coordinate", ""+this.absoluteClickedY);

    return false;
}

最后,此方法将imageview设置为新位置

   private void setAbsoluteLocation(ImageView imageView, int x, int y)
{
    RelativeLayout.LayoutParams alp = (RelativeLayout.LayoutParams) imageView.getLayoutParams();

    alp.leftMargin = x-50;
    alp.topMargin = y-50;
    imageView.setLayoutParams(alp);

}

我哪里错了?抱歉我的英语不好
