I'm a beginner, I'm creating a job search app which shows job infomation as listview where the data is from WAMP server database. I encounter a problem : Cannot resolve method 'getStringArrayList' , when I'm making a search filter for this Listview. Please see line 11 of SearchFilter.java.

getStringArrayList is a method on Bundle (such as savedInstanceState). There's no such method in Activity. Hope that helps.
Currently your infoList is an ArrayList>, something that is harder to pass directly to an activity. So find a way to represent it as an ArrayList, or find a more suitable datatype supported by Intent's putExtra-methods. Here below is a suggested solution using an ArrayList.
Passing the data into the activity with the Intent allows you to get it back in your SearchFilter. In the calling activity put something like this:
Intent i = new Intent(this, SearchFilter.class);
i.putStringArrayListExtra("com.yourpackagename.here.keynamehere", aStringArrayList);
In SearchFilter.java, put something like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
filterText = (EditText) findViewById(R.id.search_box);
filterText.addTextChangedListener(filterTextWatcher);
Intent startingIntent = getIntent();
ArrayList<String> arrayList = new ArrayList<String>();
if (startingIntent != null) {
arrayList = startingIntent.getStringArrayList("com.yourpackagename.here.keynamehere");
}
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
arrayList));
}
I can insert data into database but now face the problem that cannot retrieve data from the database and display in listview in android. Here is my coding part for retrieve data. Hope someone can help to solve this, thank you.

Add ListView in activity_forum1a.xml
<ListView
android:id="#+id/list_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"></ListView>
Take ListView reference
private ListView mList;
Initialize it in onCreate
mList = (ListView) findViewById(R.id.list_view);
Take ListAdapter class Refernce
private ListAdapter listAdapter;
Add setListAdapter method
public void setListAdapter(ListAdapter listAdapter) {
this.listAdapter = listAdapter;
mList.setAdapter(listAdapter);
}
Change updateList method to
/**
* Inserts the parsed data into the listview.
*/
private void updateList() {
ListAdapter adapter = new SimpleAdapter(this, mCommentList,
R.layout.test, new String[] { TAG_TITLE, TAG_MESSAGE,
TAG_USERNAME }, new int[] { R.id.title, R.id.message,
R.id.username });
setListAdapter(adapter);
}
and perform item click operation outside from the method, by implementing onItemClickListener

Try to override onListItemClick in fragment :
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
Intent intent = new Intent(getActivity(), ProfilePage.class);
intent.putExtra("match_detail_id", aList.get(position).get(TAG_MATCH_ID));
startActivity(intent);
}
Instead of manual setOnItemClickListener to listview so no required this code :
listview=(ListView)rootView.findViewById(android.R.id.list);
listview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
Intent intent=new Intent(getActivity().getApplicationContext(),ProfileEdit.class);
intent.putExtra("position", arg2);
startActivity(intent);
}
});
Note : when you use ListFragment no need to find Listview and set item click as well as setAdapter manually,directly get all method ready like setAdapter() and onListItemClick.
Intent intent = new Intent(getBaseContext(), NewActivity.class);
intent.putExtra("KEY", Value);
startActivity(intent)
Try with below code:
listview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Intent intent=new Intent(getActivity(),ProfileEdit.class);
intent.putExtra("match_detail_id", arg2);
startActivity(intent);
}
});
//get this data as below in ProfileEdit class
String matchId=this.getIntent().getStringExtra(""match_detail_id"");
if(matchId.trim().length()>0){

This is my Java file.
Where do I have to put the function to display the loading process?
public class AksesServerActivity extends ListActivity {
private static String link_url = "http://plnskh.zz.mu/android/berita/cekdaftar.php";
private static final String AR_ID = "id";
private static final String AR_JUDUL = "judul";
private static final String AR_CONTENT = "content";
JSONArray artikel = null;
ArrayList<HashMap<String, String>> daftar_artikel = new ArrayList<HashMap<String, String>>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
JSONParser jParser = new JSONParser();
JSONObject json = jParser.AmbilJson(link_url);
try {
artikel = json.getJSONArray("artikel");
for(int i = 0; i < artikel.length(); i++){
JSONObject ar = artikel.getJSONObject(i);
String id = ar.getString(AR_ID);
String judul = ar.getString(AR_JUDUL);
String content = ar.getString(AR_CONTENT).substring(0,100)+"...(baca selengkapnya)";
HashMap<String, String> map = new HashMap<String, String>();
map.put(AR_ID, id);
map.put(AR_JUDUL, judul);
map.put(AR_CONTENT, content);
daftar_artikel.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
this.adapter_listview();
}
public void adapter_listview() {
ListAdapter adapter = new SimpleAdapter(this, daftar_artikel,
R.layout.list_item,
new String[] { AR_JUDUL, AR_CONTENT, AR_ID}, new int[] {
R.id.judul, R.id.content, R.id.kode});
setListAdapter(adapter);
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
String kode = ((TextView) view.findViewById(R.id.kode)).getText().toString();
Intent in = new Intent(AksesServerActivity.this, DetailAksesServer.class);
in.putExtra(AR_ID, kode);
startActivity(in);
}
});
}
}
public class LongOperation extends AsyncTask<String, String, String>
{
ProgressDialog pdialog;
#Override
protected String doInBackground(String... params) {
JSONParser jParser = new JSONParser();
JSONObject json = jParser.AmbilJson(link_url);
try {
artikel = json.getJSONArray("artikel");
for(int i = 0; i < artikel.length(); i++){
JSONObject ar = artikel.getJSONObject(i);
String id = ar.getString(AR_ID);
String judul = ar.getString(AR_JUDUL);
String content = ar.getString(AR_CONTENT).substring(0,100)+"...(baca selengkapnya)";
HashMap<String, String> map = new HashMap<String, String>();
map.put(AR_ID, id);
map.put(AR_JUDUL, judul);
map.put(AR_CONTENT, content);
daftar_artikel.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
pdialog.dismiss();
this.adapter_listview();
}
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
pdialog = new ProgressDialog(NewsActivity.this);
pdialog.setMessage("Loading");
pdialog.show();
}
}
for more clarification about asynchronous task and its methods, check here
You must use AsyncTask class, override doInBackground method to perform your databse fetch, onPreExecute method to show your loading and onPostExecute to hide it. you can refer AsynTask process and AsynTask post for more information
