How can I change the color of the selected list in the navigation drawer?

I am starting with the Android Studio Browser Browser example. I customize whatever I want, everything is fine, but I cannot find how to change the selected color of the item in the navbox ... It is green at the moment and I cannot manage to change that.

I tried with the selected selector but couldn't, I was able to change the entire background, but not just the selected one.

Sorry if this is a noob question, but I spent hours yesterday on Google and here without finding: /

Green color i want to change


Finally I managed to get it to work. The problem was "android.R.layout.simple_list_item_activated_1".

This is android built in xml so you can't deal with the colors you want.

So, I created a file named nav_drawer_layout.xml

that contains the same as android.R.layout.simple_list_item_activated_1.

Then I changed it by changing the android: background attribute as follows:

<?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 selector nav_drawer_colors.xml

which 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, press_drawer and backgroung_drawer are defined in the \ colors.xml values ​​as always.

Everything is fine now, except for the drop shadow effect, which works all over the place, but not on the list. ^^ EDIT: Just specify the background color in your fragment drawer navigator layout (fragment_navigation_drawer.xml) and remove <item android:drawable="@color/backgroung_drawer" />

in file nav_drawer_colors.xml

:)

Hope this helps others who have the same problem :)

Through coding, you can achieve this when clicking the ListView item:

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 the selector:

Make one file named select.xml

in a folder drawable

.

<?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 as Listselector for ListView in xml file. How,

android:listselector="@drawable/select"

      

or use as background also

android:background="@drawable/select"

Try the following:

1.Create list_selector.xml in a portable 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 your custom layout listview.

android:background="@drawable/list_selector"
