Listview下的CheckBox设置全选或者全部选

1.先在传入Adapter的数据源mode里面标记下是否选中

public class ChooseschoolMode {    public String Schoolid;  // 学校的编号    public String Name;  // 学校的名称    boolean ischeck=false;//是否勾选    public String getSchoolid() {        return Schoolid;    }    public void setSchoolid(String schoolid) {        Schoolid = schoolid;    }    public String getName() {        return Name;    }    public void setName(String name) {        Name = name;    }    public boolean isIscheck() {        return ischeck;    }    public void setIscheck(boolean ischeck) {        this.ischeck = ischeck;    }}

2.然后再adapter里面设置checkbox的状态为标记，同时回调出去到activity界面。

public class ChooseschoolsAdapter extends BaseAdapter{    private Context context;    private LayoutInflater inflater;    private List<ChooseschoolMode> datas;    private ChooseschoolsCallback callback;    public ChooseschoolsAdapter(Context context,List<ChooseschoolMode> datas,ChooseschoolsCallback callback) {        super();        this.context = context;        inflater =LayoutInflater.from(context);        this.datas = datas;        this.callback=callback;    }    @Override    public int getCount() {        // TODO Auto-generated method stub        return datas.size();    }    @Override    public Object getItem(int position) {        // TODO Auto-generated method stub        return datas.get(position);    }    @Override    public long getItemId(int position) {        // TODO Auto-generated method stub        return position;    }    @Override    public View getView(final int position, View convertView, ViewGroup parent) {        Holder holder = null;        if (convertView == null) {            holder = new Holder();            convertView = inflater.inflate(R.layout.chooseschools_item, null);            holder.Schooname=(CheckBox)convertView.findViewById(R.id.chooseschool_cb);            convertView.setTag(holder);        } else {            holder = (Holder) convertView.getTag();        }        holder.Schooname.setText(datas.get(position).getName());        **holder.Schooname.setChecked(datas.get(position).isIscheck());//设置checkbox的选中为mode的标记**        holder.Schooname.setOnCheckedChangeListener(new OnCheckedChangeListener() {            @Override            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {                //回调                callback.Callback(position, isChecked);            }        });        return convertView;    }    public class Holder{        public  CheckBox Schooname;    }}

3.在activity里面的回调方法里拿到选中状态并设置数据源的标记，最后根据位置来循环所有的checkbox修改标记
