Question

I am trying to set a drawableLeft in a TextView in my MainActivity from my class.
How do I do this?

Thanks,

Vincent.

Like Kumar mentions above, most likely all you’ll need to do is something like this (within your MainActivity).

Drawable d = getResources().getDrawable(R.drawable.drawable_id);
Textview tv = (TextView) findViewById(R.id.text_view_id);
tv.setCompoundDrawables(d, null, null, null);

Again, this should be done within your Activity, since the findViewById() and the getResources() methods are available through the activity. If you’re trying to do this type of thing from another class, make sure to pass the activity instance to the other class, and call these methods using that activity object.
