如何在Android中为TextView动态设置drawableLeft等

1 Drawable drawable = getResources().getDrawable(resId);
2 //注意查看方法TextView.setCompoundDrawables(Drawable, Drawable, Drawable, Drawable)
3 //的注释，要求设置的drawable必须已经通过Drawable.setBounds方法设置过边界参数
4 //所以，此种方式下该行必不可少
5 drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
6 setCompoundDrawables(drawable, null, null, null);

1 setCompoundDrawablesWithIntrinsicBounds(resId, 0, 0, 0);
2 //setCompoundDrawablesWithIntrinsicBounds(getResources().getDrawable(resId), null, null, null);
