BreadcrumbsView

中文说明

Material Design Breadcrumbs Navigation Widget on Android (SDK 19+, Maybe can be lower)

How to use

Import (Gradle)

First, add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Add the dependency to your app modules:

dependencies {
    compile 'moe.feng:BreadcrumbsView:latest-version'
}

XML

Place a BreadcrumbsView to where you want in your layout xml.

For example:

<android.support.design.widget.AppBarLayout...>

	<android.support.v7.widget.Toolbar.../>

	<moe.feng.common.view.breadcrumbs.BreadcrumbsView
		android:id="@+id/breadcrumbs_view"
		android:layout_width="match_parent"
		android:layout_height="?attr/actionBarSize"
		app:popupTheme="@style/AppTheme.PopupOverlay"/>

</android.support.design.widget.AppBarLayout>

Add/Remove `BreadcrumbItem`

When your interface navigates to next step, create a new BreadcrumbItem and add it to BreadcrumbsView. (After 0.2.0, you can implement your own IBreadcrumbItem to use.)

Use removeItemAfter(int) or removeLastItem to remove items or last item.

Listen events

You can set a callback for BreadcrumbsView to receive item click/changed events.

To simplify events, I recommend to use DefaultBreadcrumbsCallback :

new DefaultBreadcrumbsCallback<BreadcrumbItem>() {
	@Override
	public void onNavigateBack(BreadcrumbItem item, int position) {
		// ...
	}

	@Override
	public void onNavigateNewLocation(BreadcrumbItem newItem, int changedPosition) {
		// ...
	}
}

breadcrumbsview's Issues

Sync BreadcrumbView items with app back stack history

Hi!
I am currently using fragments that replace the data elements on an activity and I am having a hard time keeping the app back stack "history" in-sync with BreadcrumbView.

For example:
Lets say, I have 4 fragments - A, B, C & D of the order below. All these fragments have a RecyclerView list items with onClick listeners that use a pushFragment() method which replaces Fragment accordingly.

Fragment order:
A->B->C->D

Problem:
If I click on B fragment, the BreadcrumbsView updates properly however the app back stack history still persists!
So, when a user taps Back button, he still goes to C fragment`.

I believe this could be an issue with my implementation.

Some code:

public static void pushFragment(AppCompatActivity activity, Fragment fragment) {
        int holder =  R.id.content_view_module_details_activity;
        FragmentManager fragmentManager = activity.getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager
                .beginTransaction()
                .addToBackStack(null);
        fragmentTransaction.replace(holder, fragment,
                fragment.getClass().toString());
        fragmentTransaction.commit();
    }

public void handleItemClick(View view, ClassModel m) {
        // Get current list of items
        List<IBreadcrumbItem> items = breadcrumbsView.getItems();
       // Create a new BreadcrumbItem
        ArrayList<String> list = new ArrayList<>();
        list.add(m.getTitle());
        BreadcrumbItem breadcrumbItem = new BreadcrumbItem(list);
        breadcrumbItem.setSelectedItem(m.getTitle());
        items.add(breadcrumbItem);
        breadcrumbsView.setItems(items);
        // Set data model on rootActivity
        rootActivity.setClassModel(m);
        // Goto Subjects view                          <-  goes to Fragment B
        Utils.pushFragment(rootActivity, new SubjectsListFragment());
    }
