##How to use
Add this to your build.gradle:

```Java
	dependencies {
		compile 'com.github.hymanme.tagflowlayout:tagflowlayout:0.3.0'
	}
```

#### 1. 定义xml布局
```Java 
    <com.github.hymanme.tagflowlayout.TagFlowLayout
        android:id="@+id/tag_flow_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        app:expandHint="查看更多"
        app:foldHint="点击缩回">
```

#### 2. 初始化

```Java
     mTagFlowLayout = (TagFlowLayout) findViewById(R.id.tag_flow_layout);
     mTagFlowLayout.setTitle("大家都不想搜");
     mTagFlowLayout.setTitleTextColor(getResources().getColor(R.color.colorPrimaryDark)
     mTagFlowLayout.setTitleTextSize(12);
     //最小显示高度(单位dp)
     mTagFlowLayout.setMinVisibleHeight(100);
     //最大显示高度(单位dp)
     mTagFlowLayout.setMaxVisibleHeight(400);
     mTagFlowLayout.setAnimationDuration(600);
     //设置背景颜色
     mTagFlowLayout.setBackGroundColor(getResources().getColor(R.color.primary_text));
```

#### 3. 设置adapter和监听，最好先设置监听后设置adapter
```Java
    //设置监听(单击和长按事件)
    mTagFlowLayout.setTagListener(new OnTagClickListener() {
            @Override
            public void onClick(TagFlowLayout parent, View view, int position) {
                Toast.makeText(MainActivity.this, "click==" + ((TextView) view).getText(), Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onLongClick(TagFlowLayout parent, View view, int position) {
                Toast.makeText(MainActivity.this, "long click==" + ((TextView) view).getText(), Toast.LENGTH_SHORT).show();
            }
        });

    //设置adapter
    MyTagAdapter tagAdapter = new MyTagAdapter();
    mTagFlowLayout.setTagAdapter(tagAdapter);

    //给adapter绑定数据
    tagAdapter.addAllTags(tagBeans);

    //自定义Adapter：MyTagAdapter，其中TagBean为泛型类，即每一个tag的实体类
    //在getView()里面自定义tag标签的样式
    //默认提供了两个实例tag：DefaultTagView，ColorfulTagView
    //DefaultTagView：默认tag
    //ColorfulTagView：彩色的tag
    //当然还可以自己自定义
    class MyTagAdapter extends TagAdapter<TagBean> {

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
			//定制tag的样式，包括背景颜色，点击时背景颜色，背景形状等
            DefaultTagView textView = new ColorfulTagView(MainActivity.this);
            textView.setText(((TagBean) getItem(position)).getName());
            return textView;
        }
    }
```
##默认tag样式

1. DefaultTagView (默认实心tag)
2. ColorfulTagView (彩色背景实心tag)
3. StrokeTagView	（空心带边框的tag）
4. ColorfulStrokeTagView （空心彩色边框tag）
5. 自定义tag，继承以上tag或者自定义View
