Usage

Init in xml

<com.xw.repo.BubbleSeekBar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:bsb_bubble_color="@color/color_red_light"
    app:bsb_bubble_text_color="@color/colorPrimaryDark"
    app:bsb_max="50.0"
    app:bsb_min="-50"
    app:bsb_progress="0"
    app:bsb_second_track_color="@color/color_red"
    app:bsb_section_count="5"
    app:bsb_section_text_position="bottom_sides"
    app:bsb_show_progress_in_float="true"
    app:bsb_show_section_mark="true"
    app:bsb_show_section_text="true"
    app:bsb_show_thumb_text="true"
    app:bsb_track_color="@color/color_red_light"/>

<com.xw.repo.BubbleSeekBar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:bsb_auto_adjust_section_mark="true"
    app:bsb_second_track_color="@color/color_blue"
    app:bsb_section_count="5"
    app:bsb_section_text_position="below_section_mark"
    app:bsb_show_section_mark="true"
    app:bsb_show_section_text="true"
    app:bsb_show_thumb_text="true"
    app:bsb_thumb_text_size="18sp"
    app:bsb_touch_to_seek="true"/>

Init in java (not for lite version)

mBbubbleSeekBar.getConfigBuilder()
               .min(0.0)
               .max(50)
               .progress(20)
               .sectionCount(5)
               .trackColor(ContextCompat.getColor(getContext(), R.color.color_gray))
               .secondTrackColor(ContextCompat.getColor(getContext(), R.color.color_blue))
               .thumbColor(ContextCompat.getColor(getContext(), R.color.color_blue))
               .showSectionText()
               .sectionTextColor(ContextCompat.getColor(getContext(), R.color.colorPrimary))
               .sectionTextSize(18)
               .showThumbText()
               .thumbTextColor(ContextCompat.getColor(getContext(), R.color.color_red))
               .thumbTextSize(18)
               .bubbleColor(ContextCompat.getColor(getContext(), R.color.color_green))
               .bubbleTextSize(18)
               .showSectionMark()
               .seekBySection()
               .autoAdjustSectionMark()
               .sectionTextPosition(BubbleSeekBar.TextPosition.BELOW_SECTION_MARK)
               .build();

Attentions

• There are two versions of this library.The differences as follow: version init getter/setter lite xml min, max, progress enhanced xml, java all attrs lite version is recommended.
• You must correct the offsets by setting ScrollListener when BubbleSeekBar‘s parent view is scrollable (such as ScrollView, except ViewPager), otherwise, the appearing position of the bubble may be wrong. For example:

   mContainer.setOnYourContainerScrollListener(new OnYourContainerScrollListener() {
       @Override
       public void onScroll() {
           // call this method to correct offsets
           mBubbleSeekBar.correctOffsetWhenContainerOnScrolling();
       }
   });

• When customize the section texts, you should make sure that the attr bsb_section_text_position has been set to below_section_mark at first, then follow the example below in your java code:

   mBubbleSeekBar.setCustomSectionTextArray(new BubbleSeekBar.CustomSectionTextArray() {
       @NonNull
       @Override
       public SparseArray<String> onCustomize(int sectionCount, @NonNull SparseArray<String> array) {
           array.clear();
           array.put(1, "bad");
           array.put(4, "ok");
           array.put(7, "good");
           array.put(9, "great");

           return array;
       }
   });

BTW, the attr bsb_show_thumb_text will be set to false automatically for avoiding the text coverage display problems.

• The attr bsb_always_show_bubble is not supported in the RecyclerView, ListView and GridView.
