整理之前项目，发现输入选择框还是很有意思，于是将这个组件单独拉出共享，希望这个组件对大家有用。
代码不是很多，代码里面也有相应的描述。就不做多说明了.
下面先上 MyInputSelection 控件类

在 Acitivity 中 onCreate 的用法
LinearLayout your_line = findViewById(R.id.your_line);//xml定义的LinearLayout, vertical String strs[] = {"Y好的","Z在的","H是的","3测试的","1正常的","5替代的"}; Collections.addAll(dataList,strs); MyInputSelection myInputSelection = new MyInputSelection(this); myInputSelection.setHit("输入选择内容框"); myInputSelection.setTextColor(Color.BLACK);//黑色 myInputSelection.setOptionList(dataList);//设置数据 myInputSelection.setScrollHight(500); myInputSelection.setAddListener("添加该内容", new InputSelection.AddListener() { @Override public void addOnClick(String text) { dataList.add(text);//再次添加 myInputSelection.setOptionList(dataList);//再次设置数据 } }); your_line.addView(myInputSelection, LinearLayout.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
效果图如下
输入内容后
