I want to display status and wilayah details from tbl_pegawai table.. If i select an item (name) from the spinner, i want to display the corresponding data (status and wilayah) matches with that item from the database.
Here is my android MainActivity.class file..
Spinner spinnernama, spinnerstatus, spinnerwilayah;

Adapterspinner adapter;
List<String> valueId = new ArrayList<String>();

spinnernama.setAdapter(adapter);
callData();
}
private void callData() {

if(status){
JSONArray jsonArray = response.getJSONArray("result");
for (int i = 0; i < jsonArray.length(); i++) {

ModelSpinner item =new ModelSpinner();
item.setId(jsonObject.getString("id"));
item.setNama(jsonObject.getString("nama"));
item.setStatus(jsonObject.getString("status"));

listspinner.add(item);
}
}
} catch (Exception e){

Am trying search from listview using custom adapter. i have search widget in toolbar menu and i can display widget. when i click on search icon, it expands, but when i start typing, search does not happen and list gets cleared. can someone plz trace this issue .
Here's my code from Main Activity:
public class VideoActivity extends BaseActivity {
ListView listView;
ArrayList<Video> videoArrayList;
public VideoListAdapter videoListAdapter;
String vid_id, vid_title, vid_type, vid_path, vid_img;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
initializeToolbar();
listView = (ListView) findViewById(R.id.listview_video);
videoArrayList = new ArrayList<Video>();
videoListAdapter = new VideoListAdapter(VideoActivity.this, videoArrayList);
jsonParser = new JSONParser();
new VideoTask().execute();
public class VideoTask extends AsyncTask<String, String, JSONObject> {
#Override
protected JSONObject doInBackground(String... strings) {
jsonObject = jsonParser.makeHttpRequest2(Network_constants.video_list_page, "POST");
Log.e("json data", "" + jsonObject);
return jsonObject;
}
#Override
protected void onPostExecute(JSONObject jsonObject) {
super.onPostExecute(jsonObject);
progressDialog.dismiss();
if (jsonObject != null) {
try {
jsonArray = jsonObject.getJSONArray("videos");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject1 = jsonArray.getJSONObject(i);
Log.d("jsonObject1", "" + jsonObject1);
Video video = new Video();
vid_id = jsonObject1.getString("video_id");
vid_title = jsonObject1.getString("video_channel_name");
vid_type = jsonObject1.getString("video_channel_link");
vid_path = jsonObject1.getString("video_channel_description");
vid_img = jsonObject1.getString("video_img_path");
video.set_vTitle(vid_title);
TextView t1 = (TextView) findViewById(R.id.video_title);
TextView t2 = (TextView) findViewById(R.id.video_type);
video.set_vArtist(vid_title);
video.set_vType(vid_type);
videoArrayList.add(video);
}
} catch (JSONException e) {
e.printStackTrace();
}
listView.setAdapter(videoListAdapter);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView cnt = (TextView) view.findViewById(R.id.video_type);
String cn = cnt.getText().toString();
Intent i = new Intent(VideoActivity.this, Youtube.class);
i.putExtra("url", cn);
startActivity(i);
}
});
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.clear();
getMenuInflater().inflate(R.menu.main,menu);
MenuItem menuItem = menu.findItem(R.id.menu_search);
final SearchView searchView = (SearchView) menuItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
if(TextUtils.isEmpty(newText)){
LogHelper.e("Query Result","Filter is Empty");
}else{
videoListAdapter.filter(newText);
}
return true;
}
});
return true;
}
}
And this is my CustomAdapter class :
public class VideoListAdapter extends BaseAdapter {
private Activity activity;
private static LayoutInflater inflater = null;
ImageView imageView;
private String mCurrentArtUrl;
private ArrayList<Video> video;
private ArrayList<Video> searchListView = null;
public VideoListAdapter(Activity a, ArrayList<Video> b){
this.activity = a;
this.video = b;
this.searchListView = new ArrayList<Video>();
this.searchListView.addAll(video);
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return video.size();
}
#Override
public Object getItem(int position) {
return video.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.video_list_item, null);
final TextView v_title = (TextView)vi.findViewById(R.id.video_title);
final TextView v_type = (TextView)vi.findViewById(R.id.video_type);
final TextView v_artist = (TextView)vi.findViewById(R.id.video_artist);
imageView = (ImageView) vi.findViewById(R.id.video_image);
Video video1 = video.get(position);
v_title.setText(video1.get_vTitle());
v_type.setText(video1.get_vType());
v_artist.setText(video1.get_vArtist());
String img = video1.get_vImage();
String profile = Network_constants.image_url + img;
fetchImageAsync(profile);
return vi;
}
// Filter method
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
video.clear();
if(charText.length() == 0){
video.addAll(searchListView);
}else{
for(Video v : searchListView){
LogHelper.e("Query","Entered For Loop");
if(v.get_vTitle().contains(charText)){
video.add(v);
}else{
LogHelper.e("Query","Could not create list");
}
}
}
notifyDataSetChanged();
}
}
I think my code is not working with the for loop in the filter function i guess.
You should implements Filterable in your Adapter
I have code to show listview from my server, but when I update the data from server and refresh it in my app, the listview still getting the old data, and after several minutes when I open the app again, it updated the new data that I updated before.
My Main Fragment
public class DosenFragment extends Fragment implements SwipeRefreshLayout.OnRefreshListener {
ListView list;
SwipeRefreshLayout swipe;
List<Dosen> itemList = new ArrayList<>();
AdapterDosen adapter;
private static final String TAG = DosenFragment.class.getSimpleName();
private static String url_select = Server.URL + "select.php";
public static final String TAG_ID_DOSEN = "id_dosen";
public static final String TAG_NAME = "name";

#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.matkul_list, container, false);
swipe = (SwipeRefreshLayout) v.findViewById(R.id.swipe_refresh_layout);
list = (ListView) v.findViewById(R.id.list);
adapter = new AdapterDosen(getActivity(), itemList);
list.setAdapter(adapter);
swipe.setOnRefreshListener(this);
swipe.post(new Runnable() {
#Override
public void run() {
swipe.setRefreshing(true);
itemList.clear();
adapter.notifyDataSetChanged();
callVolley();
}
});
return v;
}
#Override

callVolley();
}
private void callVolley() {

JsonArrayRequest jArr = new JsonArrayRequest(url_select, new Response.Listener<JSONArray>() {
#Override

Log.d(TAG, response.toString());
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {

Dosen item = new Dosen();
item.setId_dosen(obj.getString(TAG_ID_DOSEN));
item.setName(obj.getString(TAG_NAME));
item.setAlamat(obj.getString(TAG_STATUS));
itemList.add(item);
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter.notifyDataSetChanged();
swipe.setRefreshing(false);
}
}, new Response.ErrorListener() {

public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
swipe.setRefreshing(false);
}
});
AppController.getInstance().addToRequestQueue(jArr);
}
}
I have tried to do something with itemList.clear(); and adapter.notifyDataSetChanged(); but nothing change.
My Main Adapter
public class AdapterDosen extends BaseAdapter {

TextView alamat = (TextView) convertView.findViewById(R.id.alamat);
id.setText(data.getId_dosen());
name.setText(data.getName());
alamat.setText(data.getAlamat());
return convertView;
}
}
I'm sorry for my bad english.
Please help.
try this , add this method in your adatper
public void updateList(List<Dosen> newlist) {
items.clear();
items.addAll(newlist);
this.notifyDataSetChanged();
}
and in callVolley() method , replace this
adapter.notifyDataSetChanged();
with
adapter.updateList();
Hope this helps
Use the below Code...
/* Within the RecyclerView.Adapter class */
// Clean all elements of the recycler
public void clear() {
items.clear();
notifyDataSetChanged();
}
// Add a list of items -- change to type used
public void addAll(List<Dosen> newlist) {
items.addAll(newlist);
notifyDataSetChanged();
}
callvolly() method inside.
adapter.clear();
adapter.addAll(item);
public void onRefresh() {
callVolley();
}
please try this code i have changed something it will work fine
public class AdapterDosen extends BaseAdapter {
private Activity activity;

you can try this:
this is the adapter class code.
public class CustomTaskHistory extends ArrayAdapter<String> {
private Activity context;
ArrayList<String> listTasks = new ArrayList<String>();
String fetchRefID;
StringBuilder responseOutput;
ProgressDialog progress;
String resultOutput;
public String getFetchRefID() {
return fetchRefID;
}
public void setFetchRefID(String fetchRefID) {
this.fetchRefID = fetchRefID;
}
public CustomTaskHistory(Activity context, ArrayList<String> listTasks) {
super(context, R.layout.content_main, listTasks);
this.context = context;
this.listTasks = listTasks;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_task_history, null, true);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
LinearLayout linearLayout = (LinearLayout) listViewItem.findViewById(R.id.firstLayout);
//System.out.println("client_id" + _clientID);
//TextView textViewDesc = (TextView) listViewItem.findViewById(R.id.textViewDesc);
//ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView);
if (position % 2 != 0) {
linearLayout.setBackgroundResource(R.color.sky_blue);
} else {
linearLayout.setBackgroundResource(R.color.white);
}
textViewName.setText(listTasks.get(position));
return listViewItem;
}
}
and now in the parent class you must have already added a list view in your xml file so now display code for it is below:
CustomTaskHistory customList = new CustomTaskHistory(TaskHistory.this, task_history_name);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(customList);
you can also perform any action on clicking cells of listview.If needed code for it is below add just below the above code:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent nextScreen2 = new Intent(getApplicationContext(), SubscribeProgrammes.class);
nextScreen2.putExtra("CLIENT_ID", _clientID);
nextScreen2.putExtra("REFERENCE_ID", reference_IDs.get(i));
startActivity(nextScreen2);
Toast.makeText(getApplicationContext(), "You Clicked " + task_list.get(i), Toast.LENGTH_SHORT).show();
}
});

This is my fragment where I create the listview. When the data changed the listview is not notify. How can I do this? I make the request in viewModel using volley. I receive the next error: java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes.
