Wie die ListActivity ordnungsgemäß in Fragment? Ich bekomme immer einen Fehler.Android: Wie extend verwenden ListActivity in erweitern Fragment
Ich habe dieses Fragment:
public class Tools extends Fragment {
public Tools(){}
RelativeLayout view;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = (RelativeLayout) inflater.inflate(R.layout.tools, container, false);
getActivity().setTitle("Tools");
return view;
}
}
und ich möchte diese ListActivity Extend in diesem Fragment verwenden:
public class MainActivity extends ListActivity {
private String URL_ITEMS = "http://192.168.1.88/asd/getFixture.php";
private static final String TAG_FIXTURE = "fixture";
private static final String TAG_MATCHID = "matchId";
private static final String TAG_TEAMA = "teamA";
private static final String TAG_TEAMB = "teamB";
JSONArray matchFixture = null;
ArrayList<HashMap<String, String>> matchFixtureList = new ArrayList<HashMap<String, String>>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Call Async task to get the match fixture
new GetFixture().execute();
}
private class GetFixture extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Void doInBackground(Void... arg) {
ServiceHandler serviceClient = new ServiceHandler();
Log.d("url: ", "> " + URL_ITEMS);
String json = serviceClient.makeServiceCall(URL_ITEMS,ServiceHandler.GET);
// print the json response in the log
Log.d("Get match fixture response: ", "> " + json);
if (json != null) {
try {
Log.d("try", "in the try");
JSONObject jsonObj = new JSONObject(json);
Log.d("jsonObject", "new json Object");
// Getting JSON Array node
matchFixture = jsonObj.getJSONArray(TAG_FIXTURE);
Log.d("json aray", "user point array");
int len = matchFixture.length();
Log.d("len", "get array length");
for (int i = 0; i < matchFixture.length(); i++) {
JSONObject c = matchFixture.getJSONObject(i);
String matchId = c.getString(TAG_MATCHID);
Log.d("matchId", matchId);
String teamA = c.getString(TAG_TEAMA);
Log.d("teamA", teamA);
String teamB = c.getString(TAG_TEAMB);
Log.d("teamB", teamB);
// hashmap for single match
HashMap<String, String> matchFixture = new HashMap<String, String>();
// adding each child node to HashMap key => value
matchFixture.put(TAG_MATCHID, matchId);
matchFixture.put(TAG_TEAMA, teamA);
matchFixture.put(TAG_TEAMB, teamB);
matchFixtureList.add(matchFixture);
}
}
catch (JSONException e) {
Log.d("catch", "in the catch");
e.printStackTrace();
}
} else {
Log.e("JSON Data", "Didn't receive any data from server!");
}
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
ListAdapter adapter = new SimpleAdapter(
MainActivity.this, matchFixtureList,
R.layout.list_item, new String[] {
TAG_MATCHID, TAG_TEAMA,TAG_TEAMB
}
, new int[] {
R.id.matchId,R.id.teamA,
R.id.teamB
}
);
setListAdapter(adapter);
}
}
Dies ist der Code, mit dem ich versuchte, diese ListActivity in Fragment zu setzen:
public class terbaru extends Fragment {
public terbaru(){}
RelativeLayout view;
private String URL_ITEMS = "http://192.168.1.88/asd/getFixture.php";
private static final String TAG_FIXTURE = "fixture";

private static final String TAG_TEAMA = "teamA";
private static final String TAG_TEAMB = "teamB";
JSONArray matchFixture = null;
ArrayList<HashMap<String, String>> matchFixtureList = new ArrayList<HashMap<String, String>>();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = (RelativeLayout) inflater.inflate(R.layout.terbarus, container, false);
// Call Async task to get the match fixture
new GetFixture().execute();
}
private class GetFixture extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Void doInBackground(Void... arg) {
ServiceHandler serviceClient = new ServiceHandler();
Log.d("url: ", "> " + URL_ITEMS);
String json = serviceClient.makeServiceCall(URL_ITEMS,ServiceHandler.GET);
// print the json response in the log
Log.d("Get match fixture response: ", "> " + json);
if (json != null) {
try {
Log.d("try", "in the try");
JSONObject jsonObj = new JSONObject(json);
Log.d("jsonObject", "new json Object");
// Getting JSON Array node
matchFixture = jsonObj.getJSONArray(TAG_FIXTURE);
Log.d("json aray", "user point array");
int len = matchFixture.length();
Log.d("len", "get array length");
for (int i = 0; i < matchFixture.length(); i++) {
JSONObject c = matchFixture.getJSONObject(i);
String matchId = c.getString(TAG_MATCHID);
Log.d("matchId", matchId);
String teamA = c.getString(TAG_TEAMA);
Log.d("teamA", teamA);
String teamB = c.getString(TAG_TEAMB);
Log.d("teamB", teamB);
// hashmap for single match
HashMap<String, String> matchFixture = new HashMap<String, String>();
// adding each child node to HashMap key => value
matchFixture.put(TAG_MATCHID, matchId);
matchFixture.put(TAG_TEAMA, teamA);
matchFixture.put(TAG_TEAMB, teamB);
matchFixtureList.add(matchFixture);
}
}
catch (JSONException e) {
Log.d("catch", "in the catch");
e.printStackTrace();
}
} else {
Log.e("JSON Data", "Didn't receive any data from server!");
}
return null;
}
@Override
