Android RadioGroup和RadioButton详解

实现RadioButton由两部分组成,也就是RadioButton和RadioGroup配合使用.RadioGroup是单选组合框,可以容纳多个RadioButton的容器.在没有RadioGroup的情况下,RadioButton可以全部都选中:当多个RadioButton被RadioGroup包含的情况下,RadioButton只可以选择一个.并用setOnCheckedChangeListener来对单选按钮进行监听 1 RadioGroup相关属性: 2 RadioGroup.getC

兔子-RadioButton和RadioGroup的关系

RadioButton和RadioGroup的关系: 1.RadioButton表示单个圆形单选框.而RadioGroup是能够容纳多个RadioButton的容器 2.每一个RadioGroup中的RadioButton同一时候仅仅能有一个被选中 3.不同的RadioGroup中的RadioButton互不相干.即假设组A中有一个选中了,组B中依旧能够有一个被选中 4.普通情况下,一个RadioGroup中至少有2个RadioButton 5.普通情况下.一个RadioGroup中的Radio

Fragment + TabHost + RadioGroup

1. 使用FragMent是因为 4.0.3之后 ,摒弃了TabActivity这种用法, Demo 效果图: 先上布局XML R.layout.activity_main [html] view plaincopy <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android"

如何获取listview里面的edittext或者RadioGroup的值，涉及到引发的混乱现象

最近要实现从数据库读数据,该数据对应listview的item布局里面的RadioButton值,并且item布局里面还有EditText的控件. 如何将每一条对应的listview对应值获取出来呢? 实现原理是在作为ArrayAdapter的参数的数据源对象(如数组,集合),举例: ArrayList<MyClass> arrayList = new ArrayList<MyClass>(); ArrayAdapter arrayAdapter = new ArrayAdapte
