Android 代码当中动态改变某个控件的位置

private ImageView imageView; //小圆圈

private RelativeLayout mRlImg;

mRlImg = (RelativeLayout) view.findViewById(R.id.rl_img);

/**
* 初始化圆圈
*/
public void initCicleImg() {
imageView = new ImageView(getActivity());
imageView.setBackgroundResource(R.mipmap.count_progressicon);
imageView.setFocusable(false);
mRlImg.addView(imageView);
}

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) imageView.getLayoutParams();
params.setMargins(880, mMoveLocation + 55, 0, 0);// 通过自定义坐标来放置你的控件
imageView.setLayoutParams(params);
