Use

 Drawable[] drawables = textView.getCompoundDrawables();

Also if you want to compare two drawable.

Bitmap bitmap = ((BitmapDrawable)drawables[1] ).getBitmap();
Bitmap bitmap2 = ((BitmapDrawable)getResources().getDrawable(R.drawable.twt_hover)).getBitmap();

if(bitmap == bitmap2)
    {
        //Code blcok
    }

I don't think it is a good way to make the app create two bitmaps and compare them for each click on a TextView, right? – William Kinaan Jan 24 '13 at 21:12
probably right, but I found this answer on this thread http://stackoverflow.com/questions/9125229/comparing-two-drawables-in-android – Nimish Choudhary Jan 24 '13 at 21:39

getCompoundDrawables() returns them in the specified order Left, Top, Right, Bottom – defhlt Apr 03 '15 at 22:40

First, give your TextView an ID so you can find it in your Activity:

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="20dip"
    android:drawableTop="@drawable/new" />

Second, in your Activity find your TextView and get the compound drawables in your onCreate method after calling setContentView:

TextView textView = (TextView) findViewById(R.id.textView);
// Left, top, right, bottom drawables.
Drawable[] compoundDrawables = textView.getCompoundDrawables();
// This is the top drawable.
Drawable topCompoundDrawable = compoundDrawables[1];

I think you should use textView.getCompoundDrawables(); As for getting from drawable top i would think it would be the second drawable eg

Drawables tmp[] = textView.getCompoundDrawables();
tmp[1];  //this should be your top drawable but not 100% sure.

You cant get drawable ID in runtime. TextView uses ID only in it's constructor to load corresponding drawable. After drawable is loaded ID is gone.

In some cases there is no drawable ID at all. drawableTop can be a color rgb value.

An RGB value becomes a `ColorDrawable` – copolii Feb 04 '19 at 22:42
