Changing the width of AutoCompleteTextView in Android

Question

I've been stumped on this for a few days. I have an autoCompleteTextView and a button split 50/50 in my layout. The autocomplete works, but the suggestions only take up half of the screen (equivalent to the size that my textView takes up). How could I change this to take up the whole width?

Pardon my terrible paint skills:

Blue = AutoCompleteTextView Red = desired autocomplete suggestions

This seems like a trivial problem, but simply changing the width to fill_parent doesn't work. Any ideas xml or programatically?

SOLUTION: myAutoCompleteTextView.setDropDownWidth(ViewGroup.LayoutParams.MATCH_PARENT)

EDIT: My first question seems to be solved, but now if I switch my button and my autoCompleteTextView I get another weird problem. The width starts at where the textView starts. Leaving me with an undesireable result.

SOLUTION: See edit 1 from user: vikram

Answer 1

You can set this attribute in the description of this widget using the attribute:

android:dropDownWidth="match_parent"

If you would like to do this in java 'programmatically', use the method setDropDownWidth(int):

myAutoCompleteTextView.setDropDownWidth(int)

Edit 1:

Point pointSize = new Point();

getWindowManager().getDefaultDisplay().getSize(pointSize);

myAutoCompleteTextView.setDropDownWidth(pointSize.x);
