Android ExpandableListView / ExpandableListActivity 使用及数据更新

核心提示：addInfo("kandyli",new String[]{"12345"});}public void addInfo(String p,String[] c){group.add(p);List item = new ArrayList();for(int i=0;i<

addInfo("kandyli",new String[]{"12345"});

}

public void addInfo(String p,String[] c){

group.add(p);

List item = new ArrayList();

for(int i=0;i< p>

item.add(c[i]);

}

child.add(item);

}

public void initialData(){

group = new ArrayList();

child = new ArrayList>();

addInfo("griffinshi", new String[]{"13776117119","man","Jiangsu"});

addInfo("lancewu",new String[]{"1321134","man","Taiwan"});

addInfo("kandyli",new String[]{"12345"});

}

public void addInfo(String p,String[] c){

group.add(p);

List item = new ArrayList();

for(int i=0;i< p>

item.add(c[i]);

}

child.add(item);

}

3. 定义BaseExpandableListAdapter 并与List List> 数据相适配

Java代码

public class InfoDetailsAdapter extends BaseExpandableListAdapter {

Activity activity;

public InfoDetailsAdapter(Activity a){

activity = a;

}

//child method stub

@Override

public Object getChild(int groupPosition, int childPosition) {

// TODO Auto-generated method stub

return child.get(groupPosition).get(childPosition);

}

@Override

public long getChildId(int groupPosition, int childPosition) {

// TODO Auto-generated method stub

return childPosition;

}

@Override

public int getChildrenCount(int groupPosition) {

// TODO Auto-generated method stub

return child.get(groupPosition).size();
