Android自动填充TextView下拉宽度

Question

I want the dropdown of my auto complete TextView to cover the entire screen width. Currently the normal behaviour of the autocomplete textview is such that it covers only the width of the EditText (screenshot below).

How do I do it ? It should look somewhat like the default maps app in android.

Answer 1

http://developer.android.com/reference/android/widget/AutoCompleteTextView.html#attr_android:dropDownWidth

By putting the value -1 or fill_parent it should work

Answer 2

autoCompleteTextView.setDropDownWidth(getResources().getDisplayMetrics().widthPixels);
