How to retreive data from mysql database in RecyclerView into RadioButton

Im creating a RecyclerView using jdbc connection and mysql database. Inside the RecyclerView I am uploading data from my database into one TextView and three radioButtons . Everything works just fine, but my problem is that it only shows the first RadioButton and there is nothing in the second and third one.
Here is my java code :
public class GererVoteInvite extends AppCompatActivity {
private ArrayList<VoteItem> itemArrayList; //List items Array
private MyAppAdapter myAppAdapter; //Array Adapter
private RecyclerView recyclerView; //RecyclerView
private RecyclerView.LayoutManager mLayoutManager;
private boolean success = false; // boolean
private static final String DB_URL = "jdbc:mysql://10.0.2.2/mvoting_db_1.0.0.0";
// private static final String DB_URL = "jdbc:mysql://172.16.24.25/mvoting_db_1.0.0.0"; //"jdbc:mysql://DATABASE_IP/DATABASE_NAME";
private static final String USER = "mootaz";
private static final String PASS = "mootaz";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gerer_vote_invite);
recyclerView = (RecyclerView) findViewById(R.id.recyclerView); //REcyclerview Declaration
recyclerView.setHasFixedSize(true);
// use a linear layout manager
mLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(mLayoutManager);
itemArrayList = new ArrayList<VoteItem>(); // Arraylist Initialization
// Calling Async Task
SyncData orderData = new SyncData();
orderData.execute("");
}
// Async Task has three overrided methods,
private class SyncData extends AsyncTask<String, String, String> {
String msg = "Internet/DB_Credentials/Windows_FireWall_TurnOn Error, See Android Monitor in the bottom For details!";
ProgressDialog progress;
//Starts the progress dailog
#Override
protected void onPreExecute() {
progress = ProgressDialog.show(GererVoteInvite.this, "Synchronising",
"RecyclerView Loading! Please Wait...", true);
}
// Connect to the database, write query and add items to array list
#Override
protected String doInBackground(String... strings) {
try {
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection(DB_URL, USER, PASS); //Connection Object
if (conn == null) {
success = false;
} else {
// Change below query according to your own database.
String query = "SELECT lib_probleme , lib_solution_1 , lib_solution_2 , lib_solution_3 FROM reunion JOIN probleme JOIN solution WHERE reunion.id_reunion=probleme.id_reunion and probleme.id_probleme=solution.id_probleme ;";
Statement stmt = conn.createStatement();
java.sql.ResultSet rs = stmt.executeQuery(query);
// if resultset not null, I add items to itemArraylist using class created
if (rs != null) {
while (rs.next()) {
try {
itemArrayList.add(new VoteItem(rs.getString("lib_probleme"), rs.getString("lib_solution_1"), rs.getString("lib_solution_2"), rs.getString("lib_solution_3")));
} catch (Exception ex) {
ex.printStackTrace();
}
}
msg = "Found";
success = true;
} else {
msg = "No Data found!";
success = false;
}
}
} catch (Exception e) {
e.printStackTrace();
Writer writer = new StringWriter();
e.printStackTrace(new PrintWriter(writer));
msg = writer.toString();
success = false;
}
return msg;
}
// disimissing progress dialoge, showing error and setting up my gridview
#Override
protected void onPostExecute(String msg) {
progress.dismiss();
Toast.makeText(GererVoteInvite.this, msg + "", Toast.LENGTH_LONG).show();
if (success == false) {
} else {
try {
myAppAdapter = new MyAppAdapter(itemArrayList, GererVoteInvite.this);
recyclerView.setAdapter(myAppAdapter);
} catch (Exception ex) {
}
}
}
}
public class MyAppAdapter extends RecyclerView.Adapter<MyAppAdapter.ViewHolder> {
private List<VoteItem> values;
public Context context;
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView txtProbleme;
public RadioGroup group;
public RadioButton txtSol1;
public RadioButton txtSol2;
public RadioButton txtSol3;
public View layout;
public ViewHolder(View v) {
super(v);
layout = v;
group = (RadioGroup) v.findViewById(R.id.radio_group);
txtProbleme = (TextView) v.findViewById(R.id.tv_probleme);
txtSol1 = (RadioButton) v.findViewById(R.id.rb_1);
txtSol2 = (RadioButton) v.findViewById(R.id.rb_2);

}
}
// Constructor
public MyAppAdapter(List<VoteItem> myDataset, Context context) {
values = myDataset;
this.context = context;
}
// Create new views (invoked by the layout manager) and inflates
#Override
public MyAppAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// create a new view
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View v = inflater.inflate(R.layout.vote_view, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
// Binding items to the view
#Override
public void onBindViewHolder(ViewHolder holder, final int position) {
final VoteItem voteItem = values.get(position);
holder.txtProbleme.setText(voteItem.getProbleme());
holder.group.setTag(position);
holder.txtSol1.setText(voteItem.getSol1());
holder.txtSol2.setText(voteItem.getSol2());
holder.txtSol3.setText(voteItem.getSol3());
}
// get item count returns the list item count
#Override
public int getItemCount() {
return values.size();
}
}
}
And here is my layout.xml that containt the item for the RecyclerView

// echo no users JSON
echo json_encode($response);
}
?>
here the all files are available.
but the data is not fetched from the database.
please help me out for this..

There are lot of coding faults are there.
The Asynchronus class is return types are not in the exact manner to retrive the data.
After protected Void doInBackground(Void... args) {}is returning null then you can get null value to onPostExcute(Void args) you have to write get whole repose in doInBackground() method only if you are not returning any response.
In rawtask.xml file should contains views which are inflating by adapter but in your case other view are mentioned.
So refere this following link to get the data from webservices into listView.

Control CheckBox status

I have retrieved data from a remote db using json and i have created a custom listView with this data. I have three TextView and one CheckBox and it works perfectly. So, i have added a button that would control selected items in list and eventually transfer selected item in another activity. Problem was solved as suggested,but if i scroll list, selected items losts status.I think it depends from horder or adapter. Can someone help me? Here is my code

when user select a check box, put its corresponding data to a list.and send the list in bundle on button click.and receive it on another activity with the key.
you need to create a list like.
ArrayList<HashMap<String, String>> list_selected;
public ListatoAdapter(Context context, ArrayList<HashMap<String, String>> list_serv) {
super();
this.context = context;
this.dataList = list_serv;
list_selected = new ArrayList<HashMap<String, String>>();
}
change the listener as.
holder.Ceck.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
HashMap<String,String> data = dataList.get(position);
if(isChecked){
addToSelected(data);
}else{
removeSelected(data);
}
}
});
private void addToSelected(HashMap contact){
if(!list_selected.contains(contact))list_selected.add(contact);
}
private boolean removeSelected(HashMap contact){
return list_selected.remove(contact);
}
public ArrayList<HashMap<String, String>> getSelectedItems(){
return list_selected;
}
access the list from activity as adapter.getSelectedItems();.
declare it in your activity as global
ListatoAdapter adapter;
set adapter in this way.
adapter = new ListatoAdapter(Activity2.this, list_serv);
list.setAdapter(adapter);
and get the list in button Click as.
ArrayList<HashMap<String,String> list = adapter.getSelectedItems();

How to get image on an particular TextView String in android?

I am building an android application where the data is parsing from the JSON volley library.
Now my need is that: there Should be an particular image in front of particular Text in an ListView.
For example, if the data parsing string is ice-cream, then there should be an Ice-cream image in front of it.
Here is the code I am using for parsing data:
package tabsswipe;
public class FragmentPlay extends Fragment implements OnClickListener {
private Button ib;
private Calendar cal;
private int day;
private int month;
private int year;
private EditText et;
// Movies json url
private static final String url = "url";
private ProgressDialog pDialog;
private List<Movie> movieList = new ArrayList<Movie>();
private ListView listView;
private CustomListAdapter adapter;
String minstring, maxstring,finaldate;
EditText etxt1, etxt2;
String selItem, selItem2, selItem3, selItem4;
int ab, ba;
TextView tv1, tv2, txtsportname;
SeekBarWithTwoThumb swtt;
String firstlist;
public static ArrayList<String> array;
Calendar c = Calendar.getInstance();
int startYear = c.get(Calendar.YEAR);
int startMonth = c.get(Calendar.MONTH);
int startDay = c.get(Calendar.DAY_OF_MONTH);
Spinner spnr;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
listView = (ListView) rootView.findViewById(R.id.list1);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view,
int Position, long offset) {
// TODO Auto-generated method stub
Movie item = (Movie) adapter.getItem(Position);
viewCategorysportdetails();
// Intent intent = new Intent(rootView.getContext(),
// SingleArticleAfrica.class);
// single.title = item.getTitle();
// single.author = item.getAuthor();
// single.date = item.getDate();
// single.featured_img = item.getFeatured_img();
// single.content = item.getContent();
// single.permalink = item.getPermalink();
firstlist = item.getTitle();
txtsportname.setText(firstlist);
// Toast.makeText(getActivity(), firstlist,
// Toast.LENGTH_LONG).show();
// startActivity(intent);
}
});
adapter = new CustomListAdapter(getActivity(), movieList);
listView.setAdapter(adapter);
pDialog = new ProgressDialog(getActivity());
// Showing progress dialog before making http request
pDialog.setMessage("Loading...");
pDialog.show();
return rootView;
}
#Override
public void onStart() {
super.onStart();
// Creating volley request obj
JsonArrayRequest movieReq = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Movie movie = new Movie();
movie.setTitle(obj.getString("foodname"));
// movie.setThumbnailUrl(obj.getString("image"));
// movie.setRating(((Number) obj.get("rating"))
// .doubleValue());
// movie.setYear(obj.getInt("releaseYear"));
// adding movie to movies array
movieList.add(movie);
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(movieReq);
}
#Override
public void onDestroy() {
super.onDestroy();
hidePDialog();
}
private void hidePDialog() {
if (pDialog != null) {
pDialog.dismiss();
pDialog = null;
}
}
}
Here is code where this parse value is add using CustomListAdapter:
package info.androidhive.customlistviewvolley.adater;
public class CustomListAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<Movie> movieItems;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public CustomListAdapter(Activity activity, List<Movie> movieItems) {
this.activity = activity;
this.movieItems = movieItems;
}
#Override
public int getCount() {
return movieItems.size();
}
#Override
public Object getItem(int location) {
return movieItems.get(location);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_row, null);
if (imageLoader == null)
imageLoader = AppController.getInstance().getImageLoader();
NetworkImageView thumbNail = (NetworkImageView) convertView
.findViewById(R.id.thumbnail);
TextView title = (TextView) convertView.findViewById(R.id.title);
TextView rating = (TextView) convertView.findViewById(R.id.rating);
//TextView genre = (TextView) convertView.findViewById(R.id.genre);
TextView year = (TextView) convertView.findViewById(R.id.releaseYear);
// getting movie data for the row
Movie m = movieItems.get(position);
// thumbnail image
thumbNail.setImageUrl(m.getThumbnailUrl(), imageLoader);
// title
title.setText(m.getTitle());
// rating
rating.setText((m.getRating()));
// release year
year.setText(String.valueOf(m.getYear()));
return convertView;
}
}

I think it should work...

I hope I understood your need, but I'm not sure. Do you need to set as the background of the element view of the list an image representing the genre of the movie? Is that correct? If so:
If you take the infos from a server that you don't own, take a note of all the genres that the website uses, you put them in an array, and in the adapter depending on which genre is the movie of the list element, you change the background taking it from a drawable array. Let's say there are only 3 genres:
in xml:
<string-array name="movie_genres">
<item>Dramatic</item>
<item>Comedy</item>
<item>Action</item>
</string-array>
<string-array name"movie_genres_drawables">
<item>#drawable/dramatic_image</item>
<item>#drawable/comedy_image</item>
<item>#drawable/action_image</item>
</string-array>
then in the adapter:
static List<String> genres;
...
...
if (genres == null) {
genres = Arrays.asList((getResources().getStringArray(R.array.movie_genres)));
}
int key = genres.indexOf(getString(m.getGenre())); //Of course you should create this getter
String[] movie_genres_drawables = context.getResources().getStringArray(R.array.movie_genres_drawables);
ImageView background = (ImageView) convertView.findViewById(R.id.background);
background.setBackgroundDrawable(context.getResources().getDrawable(movie_genres_drawables[key]);
If you own the website with the movies archive, well you can take image directly from the server and put it on the list...
If I completely misunderstood your question, I'm sorry don't consider my answer at all. ;-)

You need to store the data within the views itself when comes to customizing of ListView. Trying implementing this:
public class PlacesListAdapter extends BaseAdapter
{
// private Context mContext;
private LayoutInflater mInflater;
private ArrayList<String> AL_id_text = new ArrayList<String>();
private ArrayList<String> AL_text = new ArrayList<String>();
public PlacesListAdapter(Context c, ArrayList<String> AL_name_time, ArrayList<String> AL_name_time1)
{
mInflater = LayoutInflater.from(c);
// mContext = c;
this.AL_id_text = AL_name_time;
this.AL_text = AL_name_time1;
}
public int getCount()
{
return AL_id_text.size();
}
public Object getItem(int position)
{
return AL_id_text.get(position);
}
public long getItemId(int position)
{
return position;
}
static class ViewHolder
{
TextView txt_maintext;
TextView txt_mtext;
}
public View getView(final int position, View convertView, ViewGroup parent)
{
// TODO Auto-generated method stub
final ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.place_row, null);
holder = new ViewHolder();
holder.txt_maintext = (TextView) convertView.findViewById(R.id.txt_maintext);
holder.txt_mtext = (TextView) convertView.findViewById(R.id.txt_mtext);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txt_maintext.setText(AL_id_text.get(position));
holder.txt_mtext.setText(AL_text.get(position));
return convertView;
}
}

The getView() method is called by android's ListView when it is rendering the view elements on your screen, piece by piece. You shouldn't be fetching your data in your getView() method which, more often than not, will block your UI thread.
The best way to do this would be to fetch your data beforehand, store it in the objects you like and use them to create ListAdapter instances. This way, you wouldn't need to wait for the image fetching to complete while Android is drawing the ListView for you.
So try fetching the data using
getHttpPost()
outside the getView method, preferably Asynchronously.
Populate your itemsList appropriately after fetching data using this method. Create your ListAdapter instance using this itemList data. Set this adapter to your listview.
