I've been trying to set the style of my dropdown for the autocomplete for some time now. At the moment it looks like this:
The green area is the dropdown with alternatives. I would like to make that box smaller, since it does'nt look very good at the moment with my rounded rectangle.
How do i achieve this? So far I have only been able to adjust each line in it..
Found out myself 5 minutes after putting the question here. I'll keep the question up for someone who might come across this.
You can simply put dropdown attributes when you create the autocompletetextview.
android:dropDownWidth="yourWidth"
Coudln't find any xml attribute for setting dropdown backgroundresource but the programmatical way works fine:
autoTextView.setDropDownBackgroundDrawable(this.getResources().getDrawable(R.drawable.rounded_rectangle));
This way you can define how the dropdown should look with your own drawable. If you would want to change it with xml from resource, this is an approach:
android:completionHintView="@layout/your_layout"
