Passing bundle from activity to fragment

Passing bundle from activity to fragment - java

I am fairly new to android programming and ran to a small problem. I have an activity that lets users select names from a muli-select listview. I can store it in an ArrayList fine but how do I pass that ArrayList as a bundle to be retrieved from the fragment? Thank you for any future answers.
MainActivity.java:
public class MainActivity extends Activity {
ListView myListView;
Button getResult;
ConnectionClass connectionClass;
private ArrayList<String> emp_names_list = new ArrayList<String>();
public ArrayList<Integer> emp_id_list = new ArrayList<Integer>();
MyArrayAdapter myArrayAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
connectionClass = new ConnectionClass();
emp_names_list.add("LOL");
//PAGKUHA NG RESULTS SA DB
try {
Connection con = connectionClass.CONN();
if (con == null) {
Toast.makeText(getApplicationContext(), "CONNECTION FAIL", Toast.LENGTH_LONG).show();
} else {
String query = "select * from users WHERE user_type=3";
PreparedStatement ps = con.prepareStatement(query);
ResultSet rs = ps.executeQuery();
ArrayList<String> data1 = new ArrayList<String>();
while (rs.next()) {
String fname =rs.getString("user_fname");
String lname =rs.getString("user_lname");
String name = String.valueOf(fname)+" "+String.valueOf(lname);
emp_names_list.add(fname);
}
Toast.makeText(getApplicationContext(), "FETCH SUCCESS", Toast.LENGTH_LONG).show();
}
} catch (Exception ex) {
Toast.makeText(getApplicationContext(), "FETCH FAIL", Toast.LENGTH_LONG).show();
Log.e("MYAPP", "exception", ex);
}
myListView = (ListView)findViewById(R.id.list);
//PARA SA LAYOUT
myArrayAdapter = new MyArrayAdapter(
this,
R.layout.row,
android.R.id.text1,
emp_names_list
);
myListView.setAdapter(myArrayAdapter);
myListView.setOnItemClickListener(myOnItemClickListener);
getResult = (Button)findViewById(R.id.getresult);
getResult.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
String result = "";
/*
//getCheckedItemPositions
List<Integer> resultList = myArrayAdapter.getCheckedItemPositions();
for(int i = 0; i < resultList.size(); i++){
result += String.valueOf(resultList.get(i)) + " ";
}
*/
//getCheckedItems
List<String> resultList = myArrayAdapter.getCheckedItems();
for(int i = 0; i < resultList.size(); i++){
result += String.valueOf(resultList.get(i)) + "\n";
}
myArrayAdapter.getCheckedItemPositions().toString();
//Toast.makeText(getApplicationContext(),result, Toast.LENGTH_LONG).show();

{

String query = "INSERT INTO AUTOINC(PersonName)"+"VALUES('"+names+"')";
PreparedStatement preparedStatement = con.prepareStatement(query);
preparedStatement.executeUpdate();
}
Toast.makeText(getApplicationContext(), "INSERT SUCCESS", Toast.LENGTH_LONG).show();
}
} catch (Exception ex) {
Toast.makeText(getApplicationContext(), "INSERT FAILED", Toast.LENGTH_LONG).show();
Log.e("MYAPP", "exception", ex);
}
}});
}
OnItemClickListener myOnItemClickListener = new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
myArrayAdapter.toggleChecked(position);
}};
private class MyArrayAdapter extends ArrayAdapter<String>{
private HashMap<Integer, Boolean> myChecked = new HashMap<Integer, Boolean>();
public MyArrayAdapter(Context context, int resource,
int textViewResourceId, List<String> objects) {
super(context, resource, textViewResourceId, objects);
for(int i = 0; i < objects.size(); i++){
myChecked.put(i, false);
}
}
public void toggleChecked(int position){
if(myChecked.get(position)){
myChecked.put(position, false);
}else{
myChecked.put(position, true);
}
notifyDataSetChanged();
}
public List<Integer> getCheckedItemPositions(){
List<Integer> checkedItemPositions = new ArrayList<Integer>();
for(int i = 0; i < myChecked.size(); i++){
if (myChecked.get(i)){
(checkedItemPositions).add(i);
}
}
return checkedItemPositions;
}
public List<String> getCheckedItems(){
List<String> checkedItems = new ArrayList<String>();
for(int i = 0; i < myChecked.size(); i++){
if (myChecked.get(i)){
(checkedItems).add(emp_names_list.get(i));
}
}
return checkedItems;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
if(row==null){
LayoutInflater inflater=getLayoutInflater();
row=inflater.inflate(R.layout.row, parent, false);
}
CheckedTextView checkedTextView = (CheckedTextView)row.findViewById(R.id.checkedTextView);
checkedTextView.setText(emp_names_list.get(position));
Boolean checked = myChecked.get(position);
if (checked != null) {
checkedTextView.setChecked(checked);
}
return row;
}
}
}
I have tried the following example but returns null:
Bundle bundle=new Bundle();
bundle.putBundle("bundle_DescriptioneTab",bundle_DescriptioneTab);
bundle.putBundle("bundle_User_Review",bundle_User_Review);

The first thing is that you have to declare your Class as Serializable
public class MyClass implements Serialisable{
}
and using
Bundle bundle = new Bundle();
bundle.putSerialisable("myclass",MyClass);
to send data of only class
And
If you want to send Arraylisyt use:
public class MyClass implements Parcelable{
}
Intent intent = new Intent(this,SecondaryActivity.class);
ArrayList<MyClass> mArrayList = new ArrayList<MyClass>();
and using
intent.putParcelableArrayListExtra("key", mArrayList);

You can store it in an object:
public class Thing implements Serializable {
private ArrayList<String> emp_names_list = new ArrayList<String>();
public ArrayList<Integer> emp_id_list = new ArrayList<Integer>();
[...]
}
And pass it like so:
bundle.putBundle("thing",object_thing);

save state of my game in database

In my project I download all the data of my project from a json.I download title and description as text and also download my icon and the file of games.
I can download them and also save in database and show in listview easily.
My QUESTION is about how to save that my file for game is beinng download or not?
I have two buttons. first is download button when user click it , it starts to download file.when download finish, my download button disappear and my play button appears.
I want to save this, when user for second time run the application,i save for example my second position downloaded before. and I have just my play button.
my database:
public class DatabaseHandler extends SQLiteOpenHelper {
public SQLiteDatabase sqLiteDatabase;
int tedad;
public DatabaseHandler(Context context) {
super(context, "EmployeeDatabase.db", null, 1);
}
#Override
public void onCreate(SQLiteDatabase db) {
String tableEmp = "create table emp(PersianTitle text,Description text,icon text,downloadlink text,dl integer)";
db.execSQL(tableEmp);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
public void insertData(ArrayList<String> id, ArrayList<String> name, ArrayList<String> salary, ArrayList<String> roms,String
dl) {
int size = id.size();
tedad = size;
sqLiteDatabase = this.getWritableDatabase();
try {
for (int i = 0; i < size; i++) {
ContentValues values = new ContentValues();
values.put("PersianTitle", id.get(i));
values.put("Description", name.get(i));
values.put("icon", salary.get(i));
values.put("downloadlink", roms.get(i));
values.put("dl", "0");
sqLiteDatabase.insert("emp", null, values);
}
} catch (Exception e) {
Log.e("Problem", e + " ");
}
}
public ArrayList<String> Game_Info (int row, int field) {
String fetchdata = "select * from emp";
SQLiteDatabase sqLiteDatabase = this.getReadableDatabase();
ArrayList<String> stringArrayList = new ArrayList<String>();
Cursor cu = sqLiteDatabase.rawQuery(fetchdata, null);
for (int i = 0; i < row + 1; i++) {

how to make method in my database to do this?

If I understood you properly, you can add a table, user_games for example with User ID, Game ID and Status, then you can update status whenever an action is completed.
For example Status 1 for downloading, status 2 for Downloaded or Finished and you can even add statuses like download failed, to add a re-download button...
you can do something like
public void update_status(UserID,GameID) {
String update = "UPDATE games set status = 1 where id="+Game_ID+" and UserID = " + UserID);
db.rawQuery(update, null);
}

Why List for Recyclerview returning same items in all positions? [duplicate]

This question already has answers here:
Why does my ArrayList contain N copies of the last item added to the list?
(5 answers)
Closed 5 years ago.
In my android app, I am using recycler view to show items.
(Note: This is not a duplicate question because I tried many answers from stackoverflow but no solution.)
My Problem
The recycler view showing repeated items. A single item is repeating many times even though it occurs only single time in the source DB.
I checked for the reason and note that the List object in Adapter class returning same values in all iterations. But the Fragment that sends List object to adapter class having unique values.
But only the adapter class after receiving the List object contains duplicate items
Solutions I tried
I checked Stackoverflow and added getItemId(int position) and getItemViewType(int position) in adaptor class but no solution
I checked the DB and also List view sending class both dont have duplicate items.
My Code:
InboxHostFragment.java = This class sends List object to adaptor class of recycler view:

In the above code , feedItemList returning duplicate values eventhogh the movieList list from source clas Inboxfragment.java contains unique values.
Kindly please help me with this issue. I tried many answers in Stackoverflow but I can't get solutions. I can't figure out the problem.

Use this code
for (int i = 0; i < contact.length(); i++) {
JSONObject obj1 = contact.optJSONObject(i);
ListFeed movie = new ListFeed();
movie.getuserby(obj1.getString("userby"));
movie.resid(obj1.getString("reservation_id"));
movie.setresidinbox(obj1.getString("reservation_id"));
System.out.println("reservation iddgdsds" + obj1.getString("reservation_id"));
movie.setuserbys(obj1.getString("userby"));
movie.setuserto(obj1.getString("userto"));
movie.setid(obj1.getString("room_id"));
movie.getid1(obj1.getString("id"));
movie.userto(obj1.getString("userto"));
movie.isread(obj1.getString("isread"));
movie.userbyname(obj1.getString("userbyname"));
country_symbol = obj1.getString("currency_code");
Currency c = Currency.getInstance(country_symbol);
country_symbol = c.getSymbol();
movie.setsymbol(country_symbol);
movie.setTitle(obj1.getString("title"));
movie.setThumbnailUrl(obj1.getString("profile_pic"));
movie.setstatus(obj1.getString("status"));
movie.setcheckin(obj1.getString("checkin"));
movie.setcheckout(obj1.getString("checkout"));
movie.setcreated(obj1.getString("created"));
movie.guest(obj1.getString("guest"));
movie.userbyname(obj1.getString("username"));
movie.getprice(obj1.getString("price"));
String msg = obj1.getString("message");
msg = msg.replaceAll("<b>You have a new contact request from ", "");
msg = msg.replaceAll("</b><br><br", "");
msg = msg.replaceAll("\\w*\\>", "");
movie.message(msg);
movieList.add(movie);
System.out.println(movieList.get(i).message()); // returning unique value
}
Declare ListFeed movie = new ListFeed(); into the for Loop
And remove the adapter.notifyDataSetChanged(); from for Loop.
I think this help you.

Strange behavior of custom listview with sqlite

I am trying to create a shopping cart app and everything was going great but now i am stuck for last three day did search lot in stackoverflow but could not get a answer.I am populating listview from server and there is two buttons in each row plus(for adding quantity) and minus for (decrements it). This is the screen where i am adding quantity to cart.
I am trying to insert row to sqlite database upon clicking either of two buttons and i have achieved this and i am show these data in next activity inside a listview. Here my problem starts when i insert data it shows it properly but during updation it is showing strange behavior. If i click on first three rows the insertion and updation working fine but if i scroll down and click on any item then instead of updating each time its inserting.. I know this question is quite big and lengthy but i could not find a good way to summarize it sorry.. Please help me thanks ..

Convert JSON values from Integer to String

I am using an AsyncTask to connect to the following URL:
https://api.themoviedb.org/3/movie/upcoming?api_key=6572f232190d6b55ec917726dab87783
One of the values I am having trouble with is the genre_id. As it is a JSONArray I add the values to an ArrayList. I then later want to convert these values to the String correspondence which are found here:
http://api.themoviedb.org/3/genre/movie/list?api_key=6572f232190d6b55ec917726dab87783
// Genre is json array
JSONArray genreArry = obj.getJSONArray("genre_ids");
ArrayList<Integer> genre = new ArrayList<Integer>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add(genreArry.optInt(j));
}
I'm just wondering what is the best way to do this? I am a displaying a ListView of all the information and for each row all the information is correct. I just need to convert the Genre id into the corresponding String. I have tried the code below but the TextView is always overwritten by the last value. Does anyone know of a better way to do this?
private void getGenre(int genre) {
for (int i = 0; i < genreList.size(); i++) {
Log.d("THE", "THE GENRE ADAPTER RETRIEVED IS" + i + genreList.get(i).getId() + genreList.get(i).getName());
if (genreList.get(i).getId() == genre) {
String name = genreList.get(i).getName();
mGenre.setText(name);
}
}
Solved.
I managed to get this working by doing a check in the onPostExecute of my AsyncTask
try {
JSONObject json = new JSONObject(result);
JSONArray movies = json.getJSONArray("results");
for (int i = 0; i < movies.length(); i++) {
JSONObject obj = movies.getJSONObject(i);
//Create Movie Object
Movie movie = new Movie();
//get values from JSON
movie.setTitle(obj.getString("original_title"));
movie.setPopularity(obj.getString("popularity"));
movie.setYear(obj.getString("release_date"));
movie.setThumbnailUrl(obj.getString("poster_path"));
movie.setOverView(obj.getString("overview"));
// Genre is json array
JSONArray genreArry = obj.getJSONArray("genre_ids");
ArrayList<Integer> genre = new ArrayList<Integer>();
ArrayList<String> genreName = new ArrayList<String>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add(genreArry.optInt(j));
for (int zz = 0; zz < myGenreList.size(); zz++) {
if (myGenreList.get(zz).getId() == genre.get(j)) {
String name = myGenreList.get(zz).getName();
genreName.add(name);
}
}
}
movie.setGenre(genre);
movie.setGenreName(genreName);

I prefer Volley instead of AsyncTask for simplicity, but you are more than welcome to use either. Note, AsyncTask will require quite a bit more work.
From what I have provided here, you should be able to get my screenshot after building the ListView item XML.
I loosely followed this guide to get started quickly.

Update ListView in fragment

I have a context menu in fragment A which contains DialogFragment. With the help of DialogFragment I've created a playlist which saves in MediaStore.Playlists. In fragment B I'm showing a ListView with playlists.
How to update Listview in fragment B when I am add new playlist?
P.S Im trying to usenotifydatasetchanged()` on my adapter, but it does not work.
This is PlaylistFragment where I can not update:
private ListView lvPlaylists;
private int[] images = new int[] { R.drawable.icon_playlist };
private ArrayList<HashMap<String, String>> listPlaylists = new ArrayList<HashMap<String, String>>();;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.playlists, null);
listPlaylists = getAllPlaylists(getActivity());
lvPlaylists = (ListView) v.findViewById(R.id.lvPlaylists);
List<Map<String, String>> data = new ArrayList<Map<String, String>>();
for (int i = 0; i < listPlaylists.size(); i++) {
Map<String, String> datum = new HashMap<String, String>(2);
datum.put("elementPlaylist",
listPlaylists.get(i).get("playlistName"));
datum.put("imagesPlaylist", Integer.toString(images[0]));
data.add(datum);
}
SimpleAdapter sAdapter = new SimpleAdapter(getActivity(), data,
R.layout.list_playlist_element, new String[] {
"elementPlaylist", "imagesPlaylist" }, new int[] {
R.id.tvName, R.id.ivIcon });
lvPlaylists.setAdapter(sAdapter);
lvPlaylists.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) {
String playlistId = listPlaylists.get(pos).get("playlistId");
Intent playlistSongs = new Intent(getActivity(),
PlaylistSongs.class);
playlistSongs.putExtra("playlistId", playlistId);
startActivity(playlistSongs);
}
});
return v;
}
public ArrayList<HashMap<String, String>> getAllPlaylists(Context context) {
String[] projection = { MediaStore.Audio.Playlists._ID, // 0
MediaStore.Audio.Playlists.NAME // 1
};
Cursor playListSDCardCursor = myquery(context,
MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI, projection,
null, null, MediaStore.Audio.Playlists.NAME, 0);
if (playListSDCardCursor.moveToFirst()) {
for (int i = 0; i < playListSDCardCursor.getCount(); i++) {
HashMap<String, String> playlist = new HashMap<String, String>();
playlist.put(
"playlistName",
playListSDCardCursor.getString(playListSDCardCursor
.getColumnIndex(MediaStore.Audio.Playlists.NAME)));
playlist.put(
"playlistId",
playListSDCardCursor.getString(playListSDCardCursor
.getColumnIndex(MediaStore.Audio.Playlists._ID)));
listPlaylists.add(playlist);
playListSDCardCursor.moveToNext();
}
}
playListSDCardCursor.close();
return listPlaylists;
}
public static Cursor myquery(Context context, Uri uri, String[] projection,
String selection, String[] selectionArgs, String sortOrder,
int limit) {
try {
ContentResolver resolver = context.getContentResolver();
if (resolver == null) {
return null;
}
if (limit > 0) {
uri = uri.buildUpon().appendQueryParameter("limit", "" + limit)
.build();
}
return resolver.query(uri, projection, selection, selectionArgs,
sortOrder);
} catch (UnsupportedOperationException ex) {
return null;
}
}
This is DialogFragment where i create new playlist:
public class MyDialogFragment extends DialogFragment {
Context mContext;
public MyDialogFragment() {
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage("Введите имя плейлиста:");
final EditText input = new EditText(getActivity());
input.setId(0);
builder.setView(input);
builder.setPositiveButton("Ок", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString();
Log.d("", "User name: " + value);
if (value != null) {
ContentValues cv = new ContentValues();
cv.put(MediaStore.Audio.Playlists.NAME, value);
Uri uri = getActivity().getContentResolver().insert(
MediaStore.Audio.Playlists
.getContentUri("external"), cv);
}
return;
}
});
builder.setNegativeButton("Отмена",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
return builder.create();
}
}
This is TrackFragment where i call context menu and show FragmentDialog:
public class TrackFragment extends Fragment {
private ListView lvTracks;
private static ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
private int songIndex;
private Utilities utils;
private ArrayList<HashMap<String, String>> listPlaylists = new ArrayList<HashMap<String, String>>();;
private int countPlaylist = 0;
private int itemPosition;
#Override

datum.put("songTitle", songsList.get(i).get("songTitle"));
datum.put("songArtist", songsList.get(i).get("songArtist"));
datum.put("songDuration", songsList.get(i).get("songDuration"));
datum.put("songAlbum", songsList.get(i).get("songAlbum"));
data.add(datum);
}
lvTracks = (ListView) v.findViewById(R.id.lvTracks);
lvTracks.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
songIndex = position;
writeData();
Intent mainIntent = new Intent(getActivity().getBaseContext(),
PlayerActivity.class);
mainIntent.putExtra("songIndex", position);
Bundle b = new Bundle();
b.putInt("songIndex", position);
b.putInt("mediaIndex",
Integer.parseInt(songsList.get(position).get("songId")));
mainIntent.putExtras(b);
int albumId = Integer.parseInt(songsList.get(position).get(
"songAlbum"));
Bitmap cover = utils.getAlbumart(albumId, getActivity()
.getApplicationContext());

byte[] byteArray = stream.toByteArray();
mainIntent.putExtra("albumArt", byteArray);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(mainIntent);
}
});
registerForContextMenu(lvTracks);
SimpleAdapter sAdapter = new SimpleAdapter(getActivity(), data,
R.layout.list_track_element, new String[] { "songTitle",
"songArtist", "songDuration" },
new int[] { R.id.tvSongName, R.id.tvSongArtist,
R.id.tvSongDuration });
lvTracks.setAdapter(sAdapter);
return v;
}
public void onCreateContextMenu(android.view.ContextMenu menu, View v,
android.view.ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
countPlaylist++;
if (countPlaylist > 1) {
listPlaylists.clear();
listPlaylists = getAllPlaylists(getActivity()

} else {
listPlaylists = getAllPlaylists(getActivity()
.getApplicationContext());
}
menu.setHeaderIcon(R.drawable.ic_launcher);
menu.setHeaderTitle("Добавить в плейлист");
menu.add(0, 0, 0, "Новый плейлист");
for (int i = 0; i < listPlaylists.size(); i++)
menu.add(0, i + 1, 0, listPlaylists.get(i).get("playlistName"));
}
#Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
.getMenuInfo();
itemPosition = info.position;
if (item.getItemId() == 0) {
createPlaylist(item.getItemId());
}
else {
Log.d("Playlist id",
Integer.parseInt(listPlaylists.get(item.getItemId()).get(

item.getItemId() - 1).get("playlistId")));
}
return true;

}
private void addToPlaylist(int playlistId) {

cur.moveToFirst();
final int base = cur.getInt(0);
cur.close();
ContentValues values = new ContentValues();
values.put(MediaStore.Audio.Playlists.Members.PLAY_ORDER,
Integer.valueOf(base + 1));
values.put(MediaStore.Audio.Playlists.Members.AUDIO_ID,
Integer.valueOf(songsList.get(itemPosition).get("songId")));
Log.d("mediaIndex", songsList.get(itemPosition).get("songId") + "");
resolver.insert(uri, values);
}
public ArrayList<HashMap<String, String>> getAllPlaylists(Context context) {
String[] projection = { MediaStore.Audio.Playlists._ID,
MediaStore.Audio.Playlists.NAME };
Cursor playListSDCardCursor = myquery(context,
MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI, projection,
null, null, MediaStore.Audio.Playlists.NAME, 0);
if (playListSDCardCursor.moveToFirst()) {
for (int i = 0; i < playListSDCardCursor.getCount(); i++) {
HashMap<String, String> playlist = new HashMap<String, String>();
playlist.put(
"playlistName",
playListSDCardCursor.getString(playListSDCardCursor
.getColumnIndex(MediaStore.Audio.Playlists.NAME)));
playlist.put(
"playlistId",
playListSDCardCursor.getString(playListSDCardCursor
.getColumnIndex(MediaStore.Audio.Playlists._ID)));
listPlaylists.add(playlist);
playListSDCardCursor.moveToNext();
}
}
playListSDCardCursor.close();
return listPlaylists;
}
}
I have partially solved problem adding playlist manually:
Map<String, String> datum = new HashMap<String, String>(2);
datum.put("elementPlaylist", value);
datum.put("imagesPlaylist", Integer.toString(images[0]));
PlaylistFragment.data.add(datum);
And playlist added in listview,but on click it throw :
java.lang.IndexOutOfBoundsException: Invalid index 18, size is 18

Use CursorLoader for populating your list fragment
http://developer.android.com/reference/android/content/CursorLoader.html
It will set notification uri to your Cursor sp it will update automtically
Make your fragment implement LoaderCallbacks
class PlaylistFragment extends Fragment implements LoaderCallbacks<Cursor>{
#Override
public void onLoaderReset(Loader<Cursor> arg0) {
sAdapter.swapCursor(null);
}
#Override
public Loader<Cursor> onCreateLoader(int arg0, Bundle arg1) {
return new CursorLoader(getActivity(), MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI, projection, null, null, null)
}
#Override
public void onLoadFinished(Loader<Cursor> arg0, Cursor result) {
sAdapter.swapCursor(result);
}
#Override
public void onStart(){
getLoaderManager().restartLoader(0, null, this);
}
}
Thats all, loader will automatically requry Playlist changes

Passing bundle from activity to fragment - java

You can store it in an object: public class Thing implements Serializable { private ArrayList<String> emp_names_list = new ArrayList<String>(); public ArrayList<Integer> emp_id_list = new ArrayList<Integer>(); [...] } And pass it like so: bundle.putBundle("thing",object_thing);
