android动态添加控件

RelativeLayout insertLayout = (RelativeLayout)view1.findViewById(R.id.lay);//lay是一个RelativeLayout 布局的id

ImageView img = new ImageView(MainActivity.this);//新建一个ImageView控件
img.setBackgroundColor(Color.parseColor("#ffbbb4"));

RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(100, 100);
        layoutParams.topMargin=8;
        layoutParams.leftMargin=8;
        layoutParams.rightMargin=8;
        layoutParams.bottomMargin=8;

insertLayout.addView(imgApple2,layoutParams);
