	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

dependencies {
	    compile 'com.github.shellljx:TagViewGroup:-SNAPSHOT'
}

How to use

1. Define in xml

<com.licrafter.tagview.TagViewGroup
    android:id="@+id/tagViewGroup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:inner_radius="4dp"
    app:line_width="1dp"
    app:radius="8dp"
    app:ripple_alpha="100"
    app:ripple_radius="20dp"
    app:tilt_distance="20dp"/>

2. Or in code

TagViewGroup tagViewGroup = new TagViewGroup(getContext());

3. Add animator

// set hide animator ,show animator and ripple
tagViewGroup.setHideAnimator(hideAnimator).setShowAnimator(showAnimator).addRipple();

4. Set tagAdapter

tagViewGroup.setTagAdapter(new TagAdapter() {
    @Override
    public int getCount() {
        return model.getTags().size();
    }

    @Override
    public ITagView getItem(int position) {
        return makeTagTextView(model.getTags().get(position));
    }
});

//set tagViewGroup location
tagViewGroup.setPercent(model.getPercentX(), model.getPercentY());

5. NotifyDataSetChanged

tagViewGroup.getTagAdapter().notifyDataSetChanged();

6. Handle click events

tagViewGroup.setOnTagGroupClickListener(new TagViewGroup.OnTagGroupClickListener() {
    @Override
    public void onCircleClick(TagViewGroup container) {
    //click the white circle of TagViewGroup         
    }

    @Override
    public void onTagClick(TagViewGroup container, ITagView tag, int position) {
    //clikc a tag of TagViewGroup
    }

    @Override
    public void onLongPress(TagViewGroup container) {
    
    }
});

7. Drag TagViewGroup

//you can drag tagViewGroup only if you set OnTagGroupDragListener
tagViewGroup.setOnTagGroupDragListener(new TagViewGroup.OnTagGroupDragListener() {
    @Override
    public void onDrag(TagViewGroup container, float percentX, float percentY) {
                    
    }
});
