EasyRecyclerViewIndicator

As the name suggests, you can use this library to show indicator for your RecyclerView or any View you want easily.

Installing

Use Gradle:

implementation 'com.kingfisherphuoc:easy-recyclerview-indicator:1.2'

How to use?

This is how we declare the indicators in XML (1 horizontal indicator, 1 vertical indicator):

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="0dp"
        android:layout_height="100dp"
        android:text="Hello World!"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

    <com.kingfisher.easyviewindicator.RecyclerViewIndicator
        android:id="@+id/circleIndicator"
        android:layout_width="match_parent"
        android:layout_height="20dp"
        app:avi_animation_enable="true"
        app:avi_drawable="@drawable/blue_radius"
        app:avi_drawable_unselected="@drawable/gray_radius"
        app:avi_height="10dp"
        app:avi_margin="10dp"
        app:avi_width="10dp"
        app:layout_constraintTop_toBottomOf="@+id/recyclerView">

    </com.kingfisher.easyviewindicator.RecyclerViewIndicator>


    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView2"
        android:layout_width="100dp"
        android:layout_height="0dp"
        android:layout_marginTop="10dp"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@id/circleIndicator"/>

    <com.kingfisher.easyviewindicator.AnyViewIndicator
        android:id="@+id/anyViewIndicator"
        android:layout_width="20dp"
        android:layout_height="0dp"
        android:layout_marginTop="10dp"
        app:avi_animation_enable="true"
        app:avi_drawable="@drawable/blue_radius"
        app:avi_drawable_unselected="@drawable/gray_radius"
        app:avi_height="10dp"
        app:avi_margin="10dp"
        app:avi_orientation="vertical"
        app:avi_width="10dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toRightOf="@id/recyclerView2"
        app:layout_constraintTop_toBottomOf="@+id/circleIndicator">

    </com.kingfisher.easyviewindicator.AnyViewIndicator>

For RecyclerView, it's straighforward:

recyclerView.setAdapter(new TestAdapter());
recyclerViewIndicator.setRecyclerView(recyclerView);
// If you need to change the adapter size, you should call this function
recyclerViewIndicator.forceUpdateItemCount();

If you want to display the indicator for anything you need, that's how you should do:

verticalIndicator.setItemCount(10); // set the total count of  indicator
verticalIndicator.setCurrentPosition(0); // set the current position of indicator
// Display the current number of indicator when recyclerview scrolls.
recyclerView2.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
        super.onScrollStateChanged(recyclerView, newState);
        switch (newState) {
            case RecyclerView.SCROLL_STATE_IDLE:
                int position = ((LinearLayoutManager) recyclerView.getLayoutManager()).findFirstCompletelyVisibleItemPosition();
                verticalIndicator.setCurrentPosition(position);
                break;
        }
    }
});

If you want to customize more, you can read the class: RecyclerViewIndicator.

Properties that you can config in your xml:

app:avi_width
app:avi_height
app:avi_margin
app:avi_drawable
app:avi_drawable_unselected
app:avi_animator
app:avi_animator_reverse
app:avi_animation_enable (default:true)
app:avi_orientation (default:horizontal)
app:avi_gravity (default:center)
