1.在listview item里面设置

把checked focusable clickable设置为false

2.设置ListView

3.在自定义adapter里面设置

int selectedIndex = -1;public void setSelectedIndex(int index){    selectedIndex = index;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {    RadioButton rbSelect = (RadioButton) convertView                        .findViewById(R.id.radio1);    if(selectedIndex == position){    rbSelect.setChecked(true);    }    else{    rbSelect.setChecked(false);    }}

4.在activity设置list的onItemClickListener

mList.setOnItemClickListener(new AdapterView.OnItemClickListener() {            @Override            public void onItemClick(AdapterView
      parent, View view, int position, long id) {                mChangeAdapter.setSelectedIndex(position);                mChangeAdapter.notifyDataSetChanged();            }        });

5.可选，存储单选状态在数据库，第二次打开依然把选中的item给设置为选中状态

ChangeBean bean = mData.get(position);        mHolder.tv_name.setText(bean.name);        if (selectedIndex == position) {            mHolder.iv_choice.setChecked(true);            bean.setCheck(true);            updateData(bean);        } else {            mHolder.iv_choice.setChecked(false);            bean.setCheck(false);            updateData(bean);        }

然后在activity中在setAdapter之前把选中的item设置为选中状态

mChangeAdapter = new ChangeAdapter(this);        mList.setAdapter(mChangeAdapter);        initSelect();        mChangeAdapter.refresh(mDatas);        addListener();    }    private void initSelect() {        for (int i = 0; i < mDatas.size(); i++)        {            if (mDatas.get(i).check){                mChangeAdapter.setSelectedIndex(i);                return;            }        }    }
