在代码中改变TextView的drawableLeft的图片资源

activity中直接

Drawable drawable = getResources().getDrawable(R.mipmap.ic_pay_koukuan);
drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
tv_text.setCompoundDrawables(drawable, null, null, null);

在adapter中

在引用的地方传值一个context

Drawable drawable = context.getResources().getDrawable(R.mipmap.ic_pay_koukuan);
drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
viewHolder.tv_text.setCompoundDrawables(drawable, null, null, null);
