Hi All,
I have 2 questions regarding a ListView in Android:
How can I get the color of the listview's focused row ? I tried to use the ListView.getSelector() method, which according to its documentation should give me what I'm looking for, but it's giving me a Drawable object which I don't know how to retrieve the color from (if possible...).
How can I set the color of the listview's focused row ? Here I tried to use the setSelector() method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...
Thanks!
The list selector drawable is a StateListDrawable
— it contains reference to multiple drawables for each state the list can be, like selected, focused, pressed, disabled...
While you can retrieve the drawable using getSelector()
, I don't believe you can retrieve a specific Drawable
from a StateListDrawable
, nor does it seem possible to programmatically retrieve the colour directly from a ColorDrawable
anyway.
As for setting the colour, you need a StateListDrawable
as described above. You can set this on your list using the android:listSelector
attribute, defining the drawable in XML like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:state_focused="true"
android:drawable="@drawable/item_disabled" />
<item android:state_pressed="true"
android:drawable="@drawable/item_pressed" />
<item android:state_focused="true"
android:drawable="@drawable/item_focused" />
</selector>
