问题:

I'm using MultiAutoCompleteTextView in my Android app. I need to customize the suggestion list of this control. I've tried this to customize the list separator color but this didn't worked for me. How can I update the default list divider color of MultiAutoCompleteTextView?

回答1:

In addition to setting the divider color, you need to also set the dividerHeight property or it won't work. And the Popup used by the MultiAutoCompleteTextView is actually a ListView, so setting that is correct here.

Add this to your styles.xml file:

<style name="myStyle" parent="@android:style/THeme.Holo.Light"> <!-- or whatever style you inherit -->
    <item name="android:dropDownListViewStyle">@style/DropDownListViewStyle</item>
</style>

<style name="DropDownListViewStyle" parent="android:style/Widget.ListView.DropDown">
    <item name="android:divider">@android:color/holo_orange_dark</item>
    <item name="android:dividerHeight">2px</item>
</style>

This will set the dividers in the MultiAutoCompleteTextView's Popup to orange.

You can set the divider color of the ListView showing your results. This is set with the divider attribute.

Like this: android:divider="@color/mycolor

As an alternative, you could also create a custom drawable using a ShapeDrawable, that contains it's own custom divider color, then you apply that drawable as the background to your list element.
