Item选择器(支持横向纵向布局,支持字符串,数组,集合格式数据)
适用于滚动选择年龄、城市、日期、星座等文本场景
author: jieluote
implementation 'com.github.jieluote:ItemSelecterBar:1.1'
支持的数据格式共4种,分别是 1.字符串 2.数组 3.list(不可变集合) 4.mutableList(可变集合)
val str = "---鼠牛虎兔龙蛇马羊猴鸡狗猪---"
val arrays = arrayOf("1","2","3","4","5","6","7","8","9","10","11")
val list: List = listOf("请选择城市","深圳", "北京","广州","呼和浩特","乌鲁木齐","上海","请选择城市")
val mutableList: MutableList = mutableListOf("","","","",1990,1991,1992,1993,1994,1995,1996,"","","")
支持代码和XML两种方式配置,如果同时设置了,以代码为准
代码方式,通过链式调用setXXX方法实现,最后需要调用create方法

item_selector_bar
.setOrientation(ItemSelectorBar.Orientation.horizontal) //方向
.setShowScrollbars(false) //是否显示滚动条
.setThumbHorizontal(getDrawable(R.drawable.scrollview_thumb_bg)!!) //设置滚动条Thumb背景 (Android 29及以上支持)
.setTrackHorizontal(getDrawable(R.drawable.scrollview_track_bg)!!) //设置滚动条Track背景 (Android 29及以上支持)
.setNoSelectItemTextSize(12F) //未选中文本大小
.setNoSelectItemTextColor(R.color.text_color_no_select_item) //未选中文本颜色
.setSelectItemTextSize(18F) //选中文本大小
.setSelectItemTextColor(R.color.text_color_select_item) //选中文本颜色
.setItemBgDrawable(R.drawable.item_bg) //item背景
.setItemWidth(resources.getDimensionPixelSize(R.dimen.item_width)) //宽度(如果不设置,默认为wrap)
//.setItemWidth(ViewGroup.LayoutParams.WRAP_CONTENT) //宽度wrap,文本长度都一样时推荐使用固定尺寸
.setItemHeight(resources.getDimensionPixelSize(R.dimen.item_height))//同上
.setItemHorPadding(5) //左右padding(wrap时需要有padding,否则都挤到一起了)
.setItemVerPadding(5) //上下padding,同上
.setContentText(str) //内容,可以是上方的四种格式数据
.create() //创建(create必须调用,其它可选)
item_selector_bar.setOnSelectedListener(object : ItemSelectorBar.OnSelectedListener {
override fun onSelectedItem(position: Int, view: View) {
if(view is TextView){
Log.d(TAG,"text:"+view.text+",position:"+position);
indicator_tv.setText(view.text)
}
}
})
/*
mutableList.remove(1990)
mutableList.remove(1996)
//当可变集合内容发生改变后,调用notify()进行刷新
item_selector_bar.notifyData() */
