listview里面添加checkbox实现单选，多选

public class MainActivity extends AppCompatActivity {
    private ListView listview;
    private ArrayList<bean> list;
    private boolean flag=false;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        listview = (ListView) findViewById(R.id.listview);
        list = new ArrayList<bean>();
        for (int i=0;i<15;i++){
            list.add(new bean("标题："+i,false));
        }
        listview.setAdapter(new myadapter());
        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            }
        });

    }
    class myadapter extends BaseAdapter{
        @Override
        public int getCount() {
            return list.size();
        }
        @Override
        public Object getItem(int position) {
            return list.get(position);
        }
        @Override
        public long getItemId(int position) {
            return position;
        }
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            viewholder vh=null;
            if (convertView==null){
                vh=new viewholder();
                convertView=convertView.inflate(MainActivity.this,R.layout.item,null);
                vh.tv= (TextView) convertView.findViewById(R.id.tv);
                vh.cb= (CheckBox) convertView.findViewById(R.id.cb);
                convertView.setTag(vh);
            }
            else {

            }
            vh.tv.setText(list.get(position).getTitles());

            vh.cb.setChecked(list.get(position).ischeck());
            vh.tv.setOnClickListener(new View.OnClickListener() {
                @Override

                    for (bean b:list
                         ) {
                        b.setIscheck(true);
                    }
                    notifyDataSetChanged();
                }
            });
            return convertView;
