Drawable drawable= getResources().getDrawable(R.drawable.drawable);
/// 这一步必须要做,否则不会显示.
drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
myTextview.setCompoundDrawables(drawable,null,null,null);
因为 getResources().getDrawable()已过时:
Drawable drawable =ContextCompat.getDrawable(mContext,R.drawable.drawable);
drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
myTextview.setCompoundDrawables(drawable,null,null,null);
