I am starting from the Android Studio example of navigation browser. I'm customizing everything i want, all is ok but i can't find how to change the selected item color in the navigation drawer... For now it's green and i don't manage to change that.
I tried with a selector drawable but no way, i managed to change the whole background but not juste the selected one.
Sorry if it's a noob question but i spent hours yesterday on google and here without finding :/
Finally, i managed to make it work. The problem was the "android.R.layout.simple_list_item_activated_1".
It's an android built in xml so you can't deal with colors you want.
So i created a file named nav_drawer_layout.xml
containing the same as the "android.R.layout.simple_list_item_activated_1" file.
Then i tweaked it changing the android:background attribute like this:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:background="@drawable/nav_drawer_colors"
android:minHeight="?android:attr/listPreferredItemHeightSmall" />
It refers to the the nav_drawer_colors.xml
selector that you have to create:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/selected_drawer" android:state_activated="true" />
<item android:drawable="@color/selected_drawer" android:state_selected="true" />
<item android:drawable="@color/pressed_drawer" android:state_pressed="true" />
<item android:drawable="@color/backgroung_drawer" />
</selector>
selected_drawer, pressed_drawer and backgroung_drawer are defined in the values\colors.xml as always.
Now all is ok, except the shadow effect that works everywhere but not in the listview ^^
EDIT: just specify a background color in the fragment navigation drawer layout (fragment_navigation_drawer.xml) and remove the
<item android:drawable="@color/backgroung_drawer" />
in the nav_drawer_colors.xml
file :)
Hope that it will help others who have the same problem :)

Through coding you can achieve by this on item click of ListView:
int save = -1;
listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
parent.getChildAt(position).setBackgroundColor(
Color.parseColor("#A9BCF5"));
if (save != -1 && save != position) {
parent.getChildAt(save).setBackgroundColor(
Color.parseColor("#d6e6ff"));
}
save = position;
});
Using Selector:
Make one file named select.xml
in drawable
folder.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false" android:drawable="@color/green" />
<item android:drawable="@color/transparent" />
</selector>
Now set this file to as a Listselector for ListView in xml file. Like,
android:listselector="@drawable/select"
or use as a background too
android:background="@drawable/select"

Try this:
1.Create list_selector.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/dark_green" android:state_activated="true" />
<item android:drawable="@color/sliver" android:state_focused="true" />
</selector>
2.Then set list_selector.xml
as background in listview custom designed layout.
android:background="@drawable/list_selector"
