	}

dependencies {
            implementation 'com.github.LuckyCodeer:TagLayout:1.1.0'
	}

使用方法

布局文件使用

 <com.yhw.taglayout.TagLayout
        android:id="@+id/tag_layout_1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:choiceMode="singleChoice">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:layout_margin="10dp"
            android:text="正常" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:layout_margin="10dp"
            android:text="单选" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:layout_margin="10dp"
            android:text="多选" />
    </com.yhw.taglayout.TagLayout>

或

    <com.yhw.taglayout.TagLayout
        android:id="@+id/tag_layout_2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:defaultChoicePosition="0"
        app:choiceMode="none"
        app:gravity="left"/>

布局属性

1. app:defaultChoicePosition="0" //单选时默认选中项
2. app:choiceMode="none" //设置选择模式，支持单选(singleChoice)和多选(multipleChoice) 默认(none)表示不设置选择模式
3. app:singleChoiceSupportCancel="false" //单选支持取消已选中项，默认为false
4. app:gravity="left" //对齐方式，支持 left、center、right，默认为left

动态添加数据

val list = mutableListOf("陕西西安", "新疆乌鲁木齐", "北京天安门", "西安大雁塔", "秦始皇兵马俑", "内蒙古呼伦贝尔大草原", "山西大同")
tagLayout.setAdapter(MyAdapter(list))

其它事件操作

//单击事件
tagLayout2.onItemClickListener = object : TagLayout.OnItemClickListener {
    override fun onItemClick(position: Int, view: View) {
        Toast.makeText(this@MainActivity, "点击了 $position", Toast.LENGTH_SHORT).show()
    }
}
//长按事件
tagLayout2.onItemLongClickListener = object : TagLayout.OnItemLongClickListener {
    override fun onItemLongClick(position: Int, view: View) {
        Toast.makeText(this@MainActivity, "长按了 $position", Toast.LENGTH_SHORT).show()
    }
}
//单选监听
tagLayout2.onSingleCheckedChangeListener =
    object : TagLayout.OnSingleCheckedChangeListener {
        override fun onCheckedChanged(position: Int) {
            Log.i(TAG, "选中了 $position")
        }
    }
//多选监听
tagLayout2.onMultipleCheckedChangeListener =
    object : TagLayout.OnMultipleCheckedChangeListener {
        override fun onCheckedChanged(positionList: MutableList<Int>) {
            for (position in positionList) {
                Log.i(TAG, "选中了 $position")
            }
        }
    }

//获取选中项
getIndexBtn.setOnClickListener{
    if(tagLayout2.getChoiceMode() == TagLayout.ChoiceMode.SingleChoice.choiceMode){
        //tagLayout2.getCheckedPosition() 返回-1代表未选中任何选项
        Toast.makeText(this@MainActivity, "单选了 ${tagLayout2.getCheckedPosition()}", Toast.LENGTH_SHORT).show()
    }else if(tagLayout2.getChoiceMode() == TagLayout.ChoiceMode.MultipleChoice.choiceMode){
        Toast.makeText(this@MainActivity, "多选了 ${tagLayout2.getCheckedList()}", Toast.LENGTH_SHORT).show()
    }else{
        Toast.makeText(this@MainActivity, "非选中模式，不能获取", Toast.LENGTH_SHORT).show()
    }
}

*示例代码采用Kotlin语言编写，如果你的项目是Java，用法与Kotlin基本类似
