[英]Custom ListView Adapter with divider
我想制作一個自定義列表視圖適配器。 這是我的json:
{
"Model": [{
"Group": "Group 1",
"person": [{
"Name": "Name 1",
"Country": "Country 1"
}]
}, {
"Group": "Group 2",
"person": [{
"Name": "Name 1",
"Country": "Country 1"
}, {
"Name": "Name 2",
"Country": "Country 2"
}]
}],
"Success": true
}
問題是json有2個組,我想列出每個組的子級。 另外,對於每個孩子,我需要顯示一種分隔符來分隔每個組。
這是我的自定義listview適配器:
public class GroupListAdapter extends BaseAdapter {
Context context;
ArrayList<GroupModel> groupList;
public GroupListAdapter(Context context, ArrayList<GroupModel> groupList){
this.context = context;
this.groupList = groupList;
}
@Override
public int getCount() {
return groupList.size();
}
@Override
public Object getItem(int position) {
return groupList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
static class ViewHolder{
private TextView txtName;
private TextView txtCountry;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if(convertView == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.fila_contacto, null);
viewHolder = new ViewHolder();
viewHolder.txtName = (TextView) convertView.findViewById(R.id.txtName);
viewHolder.txtCountry = (TextView) convertView.findViewById(R.id.txtCountry);
convertView.setTag(viewHolder);
}else{
viewHolder = (ViewHolder) convertView.getTag();
}
return convertView;
}
}
GroupList.java
public class GroupModel implements Serializable {
public String DescriptionDivider;
public ArrayList<ChildModel> ChildModel;
}
子模型
public class ChildModel implements Serializable {
public String Name;
public String Country;
}
編輯:同樣,當我將組列表傳遞給適配器時,僅適用於第一個組的子級。
編輯2:現在在我的組適配器中,我添加了一個列表視圖:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if(convertView == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.fila_contacto, null);
viewHolder = new ViewHolder();
GroupList groupList = groupList.get(position);
viewHolder.txtName = (TextView) convertView.findViewById(R.id.txtName);
viewHolder.lstChild = (ListView) convertView.findViewById(R.id.lstChild);
listViewChildAdapter childAdapter= new listViewChildAdapter (this.context, groupList.ChildModel);
lstChild.setAdapter(childAdapter);
convertView.setTag(viewHolder);
}else{
viewHolder = (ViewHolder) convertView.getTag();
}
return convertView;
}
編輯3:添加ListViewChildAdapter
public class listViewChildAdapter extends BaseAdapter {
Context context;
ArrayList<ChildModel> childList;
public listViewChildAdapter(Context context, ArrayList<ChildModel> childList){
this.context = context
this.childList = childList;
}
static class ViewHolder{
private TextView txtName;
private TextView txtCountry;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.child_row, parent, true);
viewHolder = new ViewHolder();
viewHolder.txtName = (TextView) convertView.findViewById(R.id.txtName);
viewHolder.txtCountry = (TextView) convertView.findViewById(R.id.txtCountry);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
ChildModel child = childList.get(position);
// region Campos NO NULLEABLES
viewHolder.txtName.setText(child.Name);
viewHolder.txtCountry.setText(child.Country);
// endregion
return convertView;
}
}
