This is a library of tags that are attached to the picture,you can add tags and ripple effects very easily.Video demo

Important Update

  1. added TagAdapter and make it easier to create TagViewGroup.

  2. moved AnimatorUtils out of the library to make it clean.

Gradle

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
    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) {

    }
});

Attributes:

attr 属性 description 描述
inner_radius 中心内圆半径
radius 中心外圆半径
line_width 线条宽度
v_distance 圆心到垂直折点的垂直距离
tilt_distance 圆心到斜线折点的垂直距离
ripple_alpha 水波纹起始透明度
ripple_maxRadius 水波纹最大半径

How to customize the animation

You can use the following properties in Property Animation:

property 属性 description 描述
LinesRatio(TagViewGroup.LINES_RATIO) 线条显现的长度占总长度的百分比
TagAlpha(TagViewGroup.TAG_ALPHA) 单个 Tag 的透明度
CircleRadius(TagViewGroup.CIRCLE_RADIUS) 中心圆半径
CircleInnerRadius(TagViewGroup.CIRCLE_INNER_RADIUS) 中心内圆半径

How to implement your own Tag view

Step 1. create a view implement ITagView interface.

Step 2. Override the following methods:

@Override
public void setDirection(DIRECTION direction) {
    mDirection = direction;
}

@Override
public DIRECTION getDirection() {
    return mDirection;
}
