listview含有radiobtn，点击实现单选

注意事项：
首先自定义ChoiceView类实现Checkable接口

public class ChoiceView extends FrameLayout implements Checkable{    private TextView mTextView;    public RadioButton mRadioButton;    public ChoiceView(Context context) {        super(context);        View.inflate(context, R.layout.listview_installment_item, this);        mTextView = (TextView) findViewById(R.id.tv_qishu);        mRadioButton = (RadioButton) findViewById(R.id.radiobtn);    }    public void setText(String text) {        mTextView.setText(text);    }    @Override    public void setChecked(boolean checked) {        mRadioButton.setChecked(checked);    }    @Override    public boolean isChecked() {        return mRadioButton.isChecked();    }    @Override    public void toggle() {        mRadioButton.toggle();    }}

单选item的布局listview_installment_item，我的布局代码用了弘阳的AutoRelativeLayout库，自己可以修改成安卓自己的RelativeLayout,另外需要注意的是radiobutton的android:clickable=”false”
android:focusable=”false”
android:focusableInTouchMode=”false”
这三个属性必须加，要不会报错

<?xml version="1.0" encoding="utf-8"?><com.lixue.aibei.autolayoutlib.AutoLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="match_parent"    android:descendantFocusability="blocksDescendants"    android:layout_height="match_parent"><com.lixue.aibei.autolayoutlib.AutoRelativeLayout    android:layout_width="match_parent"    android:layout_marginLeft="20px"    android:layout_marginRight="20px"    android:layout_height="80px">    <TextView        android:id="@+id/tv_qishu"        android:layout_width="wrap_content"        android:layout_height="wrap_content"       android:layout_centerVertical="true"        android:text="3期"       android:textColor="@color/text_gray"        />    <RadioButton        android:id="@+id/radiobtn"        android:layout_width="54px"        android:layout_height="54px"        android:layout_alignParentRight="true"        android:layout_centerVertical="true"        android:clickable="false"        android:focusable="false"        android:focusableInTouchMode="false"        android:button="@drawable/selector_radiobtn"        /></com.lixue.aibei.autolayoutlib.AutoRelativeLayout></com.lixue.aibei.autolayoutlib.AutoLinearLayout>

在activty的oncreate中，写如下代码

   for(int i=0;i<5;i++){                    PeriodandRateBean periodandRateBean=new PeriodandRateBean();                    periodandRateBean.setLimit(i+"");                    periodandRateBeanList.add(periodandRateBean);                }                ListAdapter adapter = new ArrayAdapter<PeriodandRateBean>(SocialsecurityLoanActivity.this, R.layout.listview_installment_item, periodandRateBeanList) {                    @Override                    public View getView(int position, View convertView, ViewGroup parent) {                        final ChoiceView view;                        if(convertView == null) {                            view = new ChoiceView(SocialsecurityLoanActivity.this);                        } else {                            view = (ChoiceView)convertView;                        }                        view.setText(periodandRateBeanList.get(position).getLimit()+"个月");                        return view;                    }                };                   //这个属性可以设置默认选中的项               listView.setItemChecked(fenqi_select_pos, true);

PeriodandRateBean 这个bean是自己定义的，依据自己的需求来写，我的效果最后实现的是这样，这里参考了稀土掘金大神的帖子，大家可以去看一下
