ImageView with getDrawable () to get the problem Drawable

Drawable
with ImageView with getDrawable () to get theAnd
getBaseContext (). getResources (). getDrawable () to obtain the picture is inconsistent?
For example, drawable: R.drawable.l, first set ImageView iv.setImageResource (R.drawable.l);

Then iv.getDrawable ()And
getBaseContext (). getResources (). getDrawable (R.drawable.l)
Get drawable not equal?
With == and equals are not equal, is how is it?

Why the difference?
Two drawable objects.
Png images may share the same one, but it should still be two two drawable objects.

Under the circumstances do not add extra signs, how can I judge that the two are not the same picture?

After setting iv.setImageResource (R.drawable.l) after, but also with getResources (). GetDrawable (R.drawable.l), rather than iv.getDrawable ().
You call getDrawable (R.drawable.l) twice, will get two different objects, because it will get two new ImageDrawable ().
You can use Drawable.getConstantState () to compare them, of course, sometimes being given.

ConstantState icon = mContext.getResources () getDrawable (R.drawable._smsmms) getConstantState ();..
ConstantState icon2 = imageView.getBackGround () getConstantState ().;
