ANDROID : Changing the color of ExpandableListView's group indicator -

-

the problem : i've changed app's background color white, , cannot see expandablelistview's group indicator anymore.

expandablelistview has methods change text color, background color, , divider color, nothing can see group indicator color.

i not want provide custom drawables, want change color of drawables provided android, programmatically.

i feel there must simple way this.

you have use custom drawables here. can't change android drawables provided android.
