    <com.xw.repo.BubbleSeekBar
        android:id="@+id/bubble_seek_bar_5"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="32dp"

        app:bsb_show_text="true"
        app:bsb_show_thumb_text="true"
        app:bsb_text_position="bottom"
        app:bsb_thumb_text_color="@color/colorPrimary"
        app:bsb_thumb_text_size="18sp"/>

如果BubbleSeekBar的外部容器是可滑动的控件，需要设置滑动监听来修正气泡的偏移，否则滑动后气泡出现位置可能错乱。方法如下：

   mContainer.setOnYourContainerScrollListener(new OnYourContainerScrollListener() {
       @Override
       public void onScroll() {
           // 调用修正偏移方法
           mBubbleSeekBar.correctOffsetWhenContainerOnScrolling();
       }
   });
