Android: how to play audio file?

I've create a custom ListView with title and artist TextView, and with play and stop Button. The problem is that when I press play or stop Button, audio file doesn't start. How is it possible?
I've uploaded my custom Adapter and my AudioToSendActivity class:
AudioAdapter.java
public class AudioAdapter extends ArrayAdapter<String> {
private Context mContext;
private List<String> audioList;
public AudioAdapter(#NonNull Context context, ArrayList<String> list) {
super(context, 0 , list);
mContext = context;
audioList = list;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
View listItem = convertView;
if (listItem == null)
listItem = LayoutInflater.from(mContext).inflate(R.layout.audio_row, parent, false);
String audio = audioList.get(position);
String[] items = audio.split("\n");
String title = "", artist = "";
if (items.length > 1) {
title = items[0];
}
if (items.length > 2) {
artist = items[1];
}
ImageView imageAudio = (ImageView) listItem.findViewById(R.id.audio_image);
TextView titleView = (TextView) listItem.findViewById(R.id.audio_title);
titleView.setText(title);
TextView artistView = (TextView) listItem.findViewById(R.id.audio_artist);
artistView.setText(artist);
return listItem;
}
}
AudioToSendActivity.java
public class AudioToSendActivity extends AppCompatActivity {
private ArrayList<String> arrayList;
private ListView listView;
private ArrayAdapter<String> adapter;
private static final int PERMISSION_REQUEST = 1;
private Button sendButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_audio_to_send);
listView = findViewById(R.id.audio_list_view);
sendButton = findViewById(R.id.send_audio);
if(ContextCompat.checkSelfPermission(AudioToSendActivity.this,
Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
if(ActivityCompat.shouldShowRequestPermissionRationale(AudioToSendActivity.this,
Manifest.permission.READ_EXTERNAL_STORAGE)) {
ActivityCompat.requestPermissions(AudioToSendActivity.this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, PERMISSION_REQUEST);
}
else {
ActivityCompat.requestPermissions(AudioToSendActivity.this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, PERMISSION_REQUEST);
}
}
else {
upload();
}
}
private void upload() {
listView = findViewById(R.id.audio_list_view);
arrayList = new ArrayList<>();
getAudio();
adapter = new AudioAdapter(this, arrayList); //AudioAdapter<String>(this, arrayList);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// open music player to play desired song
}
});
}
public void getAudio() {
ContentResolver contentResolver = getContentResolver();
Uri audioUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor audioCursor = contentResolver.query(audioUri, null, null, null, null);
if(audioCursor != null && audioCursor.moveToFirst()) {
int audioTitle = audioCursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
int audioArtist = audioCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
do {
String currentTitle = audioCursor.getString(audioTitle);
String currentDate = audioCursor.getString(audioArtist);
arrayList.add(currentTitle + "\n" + currentDate);
}
while (audioCursor.moveToNext());
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch(requestCode) {
case PERMISSION_REQUEST: {
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if(ContextCompat.checkSelfPermission(AudioToSendActivity.this,
Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show();
upload();
}
}
else {
Toast.makeText(this, "Permission Denied", Toast.LENGTH_SHORT).show();
finish();
}
return;
}
}
}
}
Thanks in advance to everyone.

try this. Get the uri of your file and set it like this:
//for example
public void getAudio() {
ContentResolver contentResolver = getContentResolver();
Uri audioUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor audioCursor = contentResolver.query(audioUri, null, null, null, null);
if(audioCursor != null && audioCursor.moveToFirst()) {
int audioTitle = audioCursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
int audioArtist = audioCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
//get the song path here and ...
int audiodata = audioCursor.getColumnIndex(MediaStore.Audio.Media.DATA);
do {
String currentTitle = audioCursor.getString(audioTitle);
String currentDate = audioCursor.getString(audioArtist);
//And here
String currentPath = audioCursor.getString(audioPath);
//And add it to your list however you like
arrayList.add(currentTitle + "\n" + currentDate + "\n" + currentPath);
}
while (audioCursor.moveToNext());
}
}
And then retrieve the path and make a uri from it and the rest:
Uri myAudioUri = Uri.parse("file:///" + currentPath);
//or
Uri myAudioUri = Uri.parse(currentPath);
//didn't have time to check the lines above
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(this, myAudioUri);
mp.prepare();
mp.start();

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:
public class HostInboxFragment extends Fragment {

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.

Connection ... or invalid mmi code android studio

My application consists of a listview that contains data retrieved from a database. The database has columns : cognome, nome, ruolo, telefono.
When I click on an item, a dialog containing 2 buttons is opened : call and sms.
I would like that when I click the button call, I hand the call to the number corresponding to the line.
The problem is when I click the button, there is an error message : >connection problem or invalid mmi code.

Long click removing from arrayList

After adding the removal on long click part, i tried to add a call option the same way, but it didn't work.
I wrote the code here in the second box (first box is without the call option changes that didn't work) and highlighted the changes I tried with // signs.
This is the code: (i will add my attempts of creating the long click removal if you want)
public static final int PICK_CONTACT = 1;
private ArrayList<String> contactList;
private ArrayAdapter<String> arrayAdapter;
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.activity_work__contacts);

public void onClick(View _view) {
Intent intent = new Intent(Intent.ACTION_PICK,

Anybody has an idea why it didn't work ?
Thank you

I think the best way is to implement a long click listener as you already did.
After that, I suggest you to show a message dialog for user to confirm. I share you a method to do this :
private AlertDialog showCustomDialog(final Activity act, CharSequence title, CharSequence message, CharSequence buttonYes, CharSequence buttonNo, final int selectedIndex) {
AlertDialog.Builder customDialog = new AlertDialog.Builder(act);
customDialog.setTitle(title);
customDialog.setMessage(message);
customDialog.setPositiveButton(buttonYes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
picURL.remove(selectedIndex);
}
});
customDialog.setNegativeButton(buttonNo, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
}
});
return customDialog.show();
}
Last thing : I see you're removing from the adapter, but not in the list. Maybe this is what causing your error ?

SQLite doesn't remove last object from db

I am doing an app that lets you write activities to do.
On the main activity, there's a ListView, which shows the activities according to the date especified in a DatePicker inside a DialogFragment.
I'm using SQLite to save the activities, and so far there's no problem saving them.
If you long press an item of the ListView, a context menu appears with a single option "Delete Activity", calling the method removeActivity, which deletes the activity from the static ArrayList System.activities, that stores every activity created, AND should delete the activity from the database, using the activity's attribute cod, which is unique for every instance of an activity.
public class Main extends FragmentActivity {
int mDay = Calendar.getInstance().get(Calendar.DAY_OF_MONTH);
int mMonth = Calendar.getInstance().get(Calendar.MONTH); // August, month
// starts from 0
int mYear = Calendar.getInstance().get(Calendar.YEAR);
ArrayList<String> listNames = new ArrayList<String>();
List<ActivityToDo> acts = System.activities;
boolean listHasItems = false;
int position;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
removeActivitesBeforeCurrentDate();
ToDoSQLiteHelper actdb = new ToDoSQLiteHelper(this, "db", null, 1);
SQLiteDatabase db = actdb.getReadableDatabase();
Cursor c = db.rawQuery("SELECT * FROM Activities", null);
System.activities.clear();
if (c.moveToFirst()) {
do {
ActivityToDo act = new ActivityToDo(c.getString(1),
c.getString(2), c.getString(3));
act.setDate(Integer.parseInt(c.getString(4)),
Integer.parseInt(c.getString(5)),
Integer.parseInt(c.getString(6)));
System.activities.add(act);
} while (c.moveToNext());
}
db.close();
setContentView(R.layout.main);

}
c.close();
}
#Override
protected void onPause() {
super.onPause();
this.finish();
}
}
But the db.execSQL("DELETE FROM Activities WHERE cod=" + cod); doesn't seem to work for the last activity that remains in the database. Example: I pick a date, there's two activities for the day, I delete both of them, the ListView shows the text "No activity for that date", which is what should happen, but when I start the app again, the activity that was supposingly deleted at last, appears there. Same if there's only one activity for that date, that's why I say that it doesn't seem to delete an activity if it's the last thing in the database.
Any idea why? Thanks in advance.
My SQLite class:
public class ToDoSQLiteHelper extends SQLiteOpenHelper {
// crear tabla de usuario
// agregar DATE
String sqlCreate = "CREATE TABLE Activities (cod INTEGER, name TEXT, descr TEXT, priority TEXT, day TEXT, month TEXT, year TEXT)";
public ToDoSQLiteHelper(Context contexto, String nombre,
CursorFactory factory, int version) {
super(contexto, nombre, factory, version);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(sqlCreate);
}
#Override
public void onUpgrade(SQLiteDatabase db, int versionAnterior,
int versionNueva) {
db.execSQL("DROP TABLE IF EXISTS Activities");
db.execSQL(sqlCreate);
}
}
