android – 如何使用代码设置ImageView的重力(或边距)？

我想添加 ImageView到FrameLayout与重力或边距.但是FramLayout和ImageView没有方法(实际上我找不到).选择Framelayout的原因是将ImageView放在ImageView上.

帮我吧这是紧急情况我找到解决方案.

谢谢.

以下是我的代码,帮助我理解我的问题.

FrameLayout imageFrame = new FrameLayout(mContext);
imageFrame.setLayoutParams(new GridView.LayoutParams(158,158));

ImageView frame = new ImageView(mContext);
frame = new ImageView(mContext);
frame.setLayoutParams(new LayoutParams(158,158));
frame.setScaleType(ImageView.ScaleType.CENTER_CROP);
frame.setimageResource(R.drawable.image_frame_n);

ImageView image = new ImageView(mContext);
image.setLayoutParams(new LayoutParams(148,148));
image.setScaleType(ImageView.ScaleType.CENTER_CROP);
image.setimageResource(mThumbIds[position]);
// image is needed to have a margin or gravity to be positioned at center of imageFrame

imageFrame.addView(image);
imageFrame.addView(frame);

解决方法

尝试：

image.setLayoutParams(new FrameLayout.LayoutParams(width,height,gravity));
