绝对能用-动态设置textview的drawableleft、drawableright、drawabletop、drawablebottom

项目催的紧，轻信百度导致被坑了（网上全都是这行代码

  setCompoundDrawables  (Drawable left, Drawable top, Drawable right, Drawable bottom);

），根本行不通！！！！为textview动态设置drawableleft、drawableright、drawabletop、drawablebottom的正确姿势是：

Drawable drawable = getResources().getDrawable(R.mipmap.ic_launcher);

//一定要加这行！！！！！！！！！！！
drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
textView2.setCompoundDrawables(drawable,null,null,null);
