android-layout - 控制不同组 ExpandableListView 中的按钮

Question

我在android中有一个程序，我在expandableListView组上有一个按钮，我有4组，所以我需要单独控制这4个按钮，每个按钮都有不同的活动。谁能帮我？

Code for MainActivity:
public class MainActivity extends Activity {
final Context context = this;
private static final String[][] data = {{" "},{"a1","a2"},{"s1","s2","s3"},{"t1","t2","t3"}};

private ExpandableListView expandableListView;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
expandableListView = (ExpandableListView)findViewById(R.id.lvExp);
expandableListView.setAdapter(new ExpandableListAdapter(context, this, data));
}




Here`s my code for Adapter:
class ExpandableListAdapter extends BaseExpandableListAdapter {
        public Context context;
        CheckBox checkBox;
    private LayoutInflater vi;
    private String[][] data;
    int _objInt;
    public static Boolean checked[] = new Boolean[1];

    HashMap<Long,Boolean> checkboxMap = new HashMap<Long,Boolean>();
    private static final int GROUP_ITEM_RESOURCE = R.layout.list_group;
    private static final int CHILD_ITEM_RESOURCE = R.layout.list_item;
    public String []check_string_array;

    public ExpandableListAdapter(Context context, Activity activity, String[][] data) {
        this.data = data;
        this.context = context;
        vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        _objInt = data.length;
        check_string_array = new String[_objInt];
        popolaCheckMap();
    }
    public void popolaCheckMap(){

        SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(context); 
        String buffer = null;

        for(int i=0; i<_objInt; i++){
                buffer = settings.getString(String.valueOf((int)i),"false");
                if(buffer.equals("false"))
                        checkboxMap.put((long)i, false);
                else checkboxMap.put((long)i, true);
        }
    }

    public class CheckListener implements OnCheckedChangeListener{

        long pos;

        public void setPosition(long p){
            pos = p;
        }

        @Override
        public void onCheckedChanged(CompoundButton buttonView,
                boolean isChecked) {
                Log.i("checkListenerChanged", String.valueOf(pos)+":"+String.valueOf(isChecked));
            checkboxMap.put(pos, isChecked);
            if(isChecked == true) check_string_array[(int)pos] = "true";
            else                                  check_string_array[(int)pos] = "false";
           // save checkbox state of each group
            SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(context);                
            SharedPreferences.Editor preferencesEditor = settings.edit();
            preferencesEditor.putString(String.valueOf((int)pos), check_string_array[(int)pos]);
            preferencesEditor.commit();
        }
    }
