android 如何動態設置View的margin和padding

感謝大佬：https://blog.csdn.net/a107494639/article/details/7341077

1.動態設置padding，拿ImageView為例：

ImageView imageView = new ImageView(this);
imageView.setPadding(5,5,5,5)

2.動態設置margin

拿LinearLayout里邊放ImageVIew例：

LinearLayout layout = (LinearLayout) convertView.findViewById(R.id.linearlayout);
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(100, 100);
params.setMargins(5, 5, 5, 5);
layout.addView(imageView);
