        android:id="@+id/side_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
```

#### **set `OnTouchLetterChangeListener`**

```java
    mSideBarView.setOnTouchLetterChangeListener(new WaveSideBarView.OnTouchLetterChangeListener() {
            @Override
            public void onLetterChange(String letter) {
                int pos = adapter.getLetterPosition(letter);

                if (pos != -1) {
                    mRecyclerView.scrollToPosition(pos);
                }
