Hello my good friends,

When I try to set a drawableLeft in my android application like this:

TextView textView = new TextView() findViewById(R.id.mainList);
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.mul, 0, 0, 0);

I get a error with the first line:

"The constructer TextView() is undefined."
and
"The method findViewById(int) is undefined for the type Item."

How can I solve this? I am working in a class.

Thanks!

Stay sweet!

Update:

Basicly my question is: How can I access a TextView and set a drawableLeft (or for example text) in for example my Main Activity from a diffrent class?

The doc:

TextView.setCompoundDrawablesWithIntrinsicBounds(int, int, int, int)[] @ developer.android.com/reference/android[^]

so your call of the method seems to be fine. Have you set a number value for the call R.drawable.mul ? That one might not be there when you request it.

You can also use a variable first and set that one into your code to check the value while debugging:

TextView textView = new TextView() findViewById(R.id.mainList);
int iLeft = R.drawable.mul;
textView.setCompoundDrawablesWithIntrinsicBounds(iLeft, 0, 0, 0);

Other idea: When is the view added to the app? is it already existing when you're trying to draw the bound? should you update the view (graphically)?
