Hansel And Gretel

Android library providing bread crumbs for compatibility fragments.

Usage

For a working implementation of this project see the sample/ folder.

1. Include the widget in your view. This should usually be placed directly above the container in which the associated fragments will be displayed.

   <android.support.v4.app.FragmentBreadCrumbs
       android:id="@+id/breadcrumbs"
       android:layout_width="fill_parent"
       android:layout_height="40dp" />
   

2. In your onCreate method, bind the widget to the activity.

   FragmentBreadCrumbs crumbs = (FragmentBreadCrumbs)findViewById(R.id.breadcrumbs);
   crumbs.setActivity(this);
   

3. Add the required style attributes to your theme.

   <item name="hagDividerVertical">@drawable/hag__divider_dark</item>
   <item name="hagSelectableItemBackground">@drawable/hag__background_dark</item>
   

   or

   <item name="hagDividerVertical">@drawable/hag__divider_dark</item>
   <item name="hagSelectableItemBackground">@drawable/hag__background_dark</item>
   

   or specify your own drawables for the divider and background.

4. (Optional) Set the title of the initial view. This can be useful when the initial activity view has a default fragment.

   //continued from above
   crumbs.setTitle("Settings", null);
