WaveSideBar project
一个快速跳跃分组的侧边栏控件，示例中配合RecyclerView实现。
波浪的实现采用了三段二次贝塞尔曲线，附一张手稿草图，仅供参考。
Usage
use WaveSideBarView in the layout file
<cc.solart.wave.WaveSideBarView
android:id="@+id/side_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>set OnTouchLetterChangeListener
mSideBarView.setOnTouchLetterChangeListener(new WaveSideBarView.OnTouchLetterChangeListener() {
@Override
public void onLetterChange(String letter) {
int pos = adapter.getLetterPosition(letter);
if (pos != -1) {
mRecyclerView.scrollToPosition(pos);
}
}
});Thanks
used PinnedHeaderDecoration in RecyclerItemDecoration
