Android--动态添加Margin和Padding

1.动态设置padding，拿ImageView为例：

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

2.动态设置margin

拿LinearLayout里边放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);
