android listview每个item里面有个radiobutton，怎么弄radibutton的单选事件
如题 android listview每个item里面有个radiobutton，怎么弄radibutton的单选事件，点击某个radio的时候它选中，其他的取消， 牛人们，，，请给出具体的代码
在网上找的 都没有效果，要么就是只能点击一个不能换成其他的了，要么就是都选上了。。。
final RadioButton mRadioButton = (RadioButton) view
.findViewById(R.id.report_item_check);
mRadioButton.setChecked(false);//先把所有的设置为false
if(mRadioButton.getId()<=position){
mRadioButton.setId(position);
}
mRadioButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
//在这儿实现整个listView item 中的radioButton的单选
if(isChecked)
{
if(temp!=-1)
{
RadioButton tempRadio =(RadioButton)view.findViewById(temp);
if(tempRadio !=null)
{
tempRadio.setChecked(false);
}
}
temp = buttonView.getId();
}
}
});
if (position == mRadioButton.getId()) {
mRadioButton.setChecked(true);
} else {
mRadioButton.setChecked(false);
}
//radioButton.setId(position);
//radioButton.setChecked(false);
//radioButton
//.setOnCheckedChangeListener(new OnCheckedChangeListener() {
//
//public void onCheckedChanged(
//CompoundButton buttonView, boolean isChecked) {
//if (radioButton.isChecked()==true) {
//temp=btn_id;
//btn_id = radioButton.getId();
//if (temp != -1 && temp != btn_id) {
//RadioButton tempButton = (RadioButton) view
//.findViewById(temp);
//if (tempButton != null) {
//tempButton.setChecked(false);
//}
//}
//}
//
//}
//});
//if (btn_id == position) {
//radioButton.setChecked(true);
//checked_map=map;
//} else {
//radioButton.setChecked(false);
//}
//

[解决办法]
发一下你的adapter的代码。

我回答过的一个帖子，你们的需求类似。
[解决办法]
就是在adapter设置一个isClickedPosition
然后在getview的时候
只对isClickedPosition的view的radio设置isChecked（true）
在oncheckedchange中对adapter进行刷新
[解决办法]
ListView本身自带单选和多选模式，通过
listview.setChoiceMode()
可以设置
