If you want use this view, the operation is as follows:
Because the IndicatorTabBar has custom attributes, if you want use them, you must add your own namespace in your xml file in the first component:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:widgets="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
Then, add it into your layout file, to use the IndicatorTabBar:
<com.andy.widgets.IndicatorTabBar
android:id="@+id/tab_indicator"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="@color/bg_color"
widgets:tab_text_color="@color/tab_text_color"
widgets:tab_text_selected_color="@color/tab_text_selected_color"
widgets:tab_text_size="18sp" />
