Trying to change tab indicator color

I've generated a custom action bar here and everything works except for tabs. Tab indicator and tab background color stays the same no matter what.

tab_indicator_ab_recorder.xml file:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_recorder" />
<item android:state_focused="false" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_recorder" />

<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_focused_recorder" />
<item android:state_focused="true" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_recorder" />

<!-- Pressed -->
<!--    Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_recorder" />
<item android:state_focused="false" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_recorder" />

<!--    Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_recorder" />
<item android:state_focused="true" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_recorder" />

Accourding to documentation, I need to override background attribute of tab layout with this xml file. But how do I do it? I tried doing this:

<TabWidget
    android:id="@android:id/tabs"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/tab_indicator_ab_recorder"/>

but this isn't working. Any idea how could I fix this?

You can do this simply by

app:tabIndicatorColor

property in xml

<android.support.design.widget.TabLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@id/pages_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:tabIndicatorColor="@android:color/white"
app:tabIndicatorHeight="4dp"/>

You could specify the tab indicator in your java code. Below is what I did when setting up the tab host. Added complete code with two tabs for clarification. The getTabIndicator() method is the relevant part though.

private void initTabs(String currentTab) {
    mTabHost = (TabHost) mRootView.findViewById(R.id.orderTabHost);
    mTabHost.setup();

    // Add drawing tab
    TabHost.TabSpec drawingTab = mTabHost.newTabSpec(DRAWING_TAB_TAG);
    drawingTab.setContent(R.id.tab_drawing_container);
    String drawingTitle = getResources().getString(R.string.drawing_title);
    drawingTab.setIndicator(getTabIndicator(drawingTitle));
    mTabHost.addTab(drawingTab);

    // Add detail tab
    TabHost.TabSpec detailTab = mTabHost.newTabSpec(DETAIL_TAB_TAG);
    detailTab.setContent(R.id.tab_info_container);
    String detailTitle = getResources().getString(R.string.detail_title);
    detailTab.setIndicator(getTabIndicator(detailTitle));
    mTabHost.addTab(detailTab);
}

// Call this for every tab.
private View getTabIndicator(String tabTitle) {
    View tabIndicator = LayoutInflater.from(getActivity()).inflate(
            R.layout.tab_indicator_holo, mTabHost.getTabWidget(), false);
    TextView title = (TextView) tabIndicator
            .findViewById(android.R.id.title);
    title.setText(tabTitle);
    return tabIndicator;
}

I guess you would need to modify your tab xml files, such as tab_selected_recorder.xml to change tab's background according to your needs. It could be helpful if you provided one of these files. For example tab_selected_recorder.xml could be something like : 

<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle" >
    <solid android:color="#888888" />
</shape>
