我已经创建了一个带有标题的列表视图，但我无法对同一标题下的项目进行分组。
有人可以建议我该怎么做吗？
以下是将项目显示到列表视图中的代码：
public class OrganizationList extends Activity implements OnClickListener {
ListView lv;
SimpleAdapter simpleAdapter;
ArrayList<HashMap<String, String>> videosList;
// Progress Dialog
private ProgressDialog pDialog;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
JSONArray videos = null;
// url to get all videos
private static String url_video = "http://10.0.2.2/android_connect/get_organization.php";
//JSON Nodes
private static final String TAG_POSITION = "position";
private static final String TAG_URL = "URL";
private static final String TAG_MEMBER = "name";
private static final String TAG_SUCCESS = "success";
private static final String TAG_NAME = "members";
protected static final int GET_INTENT_CODE = 0;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video);
Button refresh = (Button)findViewById(R.id.btn_refresh);
refresh.setOnClickListener(this);
TextView header = (TextView)findViewById(R.id.text_header);
header.setText("Videos (视频)");
ImageButton home = (ImageButton)findViewById(R.id.btn_home);
home.setOnClickListener(this);
// Hashmap for ListView
videosList = new ArrayList<HashMap<String, String>>();
//Get adapter
simpleAdapter = new SimpleAdapter(OrganizationList.this, videosList, R.layout.list_date_item, new String[] {TAG_POSITION, TAG_MEMBER},
new int[] { R.id.text_header, R.id.name});
//Get Listview
lv = (ListView) findViewById(R.id.lst_name);
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String videoName = ((TextView) view.findViewById(R.id.name)).getText()
.toString();
Log.d("row click:", videoName);
}
});
// Loading videos in Background Thread
new LoadAllVideos().execute();
}
/**
* Background Async Task to Load all product by making HTTP Request
* */
class LoadAllVideos extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(OrganizationList.this);
pDialog.setMessage("Loading" + "\n" + "Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
/**
* getting All videos from url
* */
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
// getting JSON string from URL
JSONObject json = jParser.makeHttpRequest(url_video, "GET", params);
// Check your log cat for JSON reponse
Log.d("All videos: ", json.toString());
try {
// Checking for SUCCESS TAG
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// videos found
// Getting Array of videos
videos = json.getJSONArray(TAG_NAME);
// looping through All videos
for (int i = 0; i < videos.length(); i++) {
JSONObject c = videos.getJSONObject(i);
// Storing each json item in variable
String post = c.getString(TAG_POSITION);
String name = c.getString(TAG_MEMBER);
//videosList.add(c.getString(TAG_COMPANY));
//Log.d("item Name:", name);
//Log.d("companyNAme", videosList.get(0));
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_POSITION, post);
map.put(TAG_MEMBER, name);
// adding HashList to ArrayList
videosList.add(map);
//System.out.println(map);
}
}
else {
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog after getting all videos
pDialog.dismiss();
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
/**
* Updating parsed JSON data into ListView
* */
// ListView Adapter
lv = (ListView) findViewById(R.id.lst_name);
lv.setAdapter(simpleAdapter);
}
});
}
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.getId() == R.id.btn_refresh)
{
videosList.clear();
new LoadAllVideos().execute();
}
else if(v.getId() == R.id.btn_home)
{
Intent intent = new Intent();
intent.setClassName("com.scba", "com.scba.Menu");
finish();
}
}
}
