I am trying to sort music list by date, name, album, artist, duration and size after I click sort getting life cycle exception
Here is my code
Click action code
I am trying to sort songs by date added this function called.
after saving sorting type I have colsed the bottomsheet and recreate the activity using recreate funstion.
lv_date.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
MPPreferenceManager.setString(MPConstants.SORTING, "sort_by_date");
bottomSheetDialog.dismiss();
MainActivity.this.recreate();
}
});
Sorting code is here
public static ArrayList<SongsModel> getAllAudio(Context context) {
String sortOrder = MPPreferenceManager.getString(MPConstants.SORTING, "");
ArrayList<String> duplicate = new ArrayList<>();
albums.clear();
ArrayList<SongsModel> songsModels = new ArrayList<>();
String order = null;
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Log.e(TAG, "getAllAudio: sort list: " + sortOrder );
switch (sortOrder){
case "sort_by_date":
order = MediaStore.MediaColumns.DATE_ADDED + " ASC" ;
break;
case "sort_by_name":
order = MediaStore.MediaColumns.TITLE + " ASC" ;
break;
case "sort_by_album":
order = MediaStore.MediaColumns.ARTIST + " ASC" ;
break;
case "sort_by_artist":
order = MediaStore.MediaColumns.DURATION + " ASC" ;
break;
case "sort_by_size":
order = MediaStore.MediaColumns.SIZE + " ASC" ;
break;
}
String[] projection = {
MediaStore.Audio.Media.ALBUM,
MediaStore.Audio.Media.ARTIST,
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.DURATION,
MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media._ID,
};
Cursor cursor = context.getContentResolver().query(uri, projection, null, null, order);
if (cursor != null) {
while (cursor.moveToNext()) {
String album = cursor.getString(0);
String artist = cursor.getString(1);
String title = cursor.getString(2);
String duration = cursor.getString(3);
String path = cursor.getString(4);//path
SongsModel songsModel = new SongsModel(path, title, artist, album, duration);
songsModels.add(songsModel);
if (!duplicate.contains(album)) {
albums.add(songsModel);
duplicate.add(album);
}
}
cursor.close();
}
return songsModels;
}
Here is my sort list design

I am getting only name & birthday using the code below. But I need phone number & email also. It would be great if anyone can help me out. Thanks.
private void getContacts() {
Uri uri = ContactsContract.Data.CONTENT_URI;
String[] projection = new String[]{
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Event.CONTACT_ID,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Email.DATA,
ContactsContract.CommonDataKinds.Event.START_DATE
};
String where = ContactsContract.Data.MIMETYPE + "= ? AND " +
ContactsContract.CommonDataKinds.Event.TYPE + "=" +
ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY;
String[] selectionArgs = new String[]{
ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE
};
String sortOrder = null;
ContentResolver contentResolver = this.getActivity().getContentResolver();
Cursor cursor = contentResolver.query(uri, projection, where, selectionArgs, sortOrder);
int nameColumn = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int numberColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
int emailColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
int bithDayColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Event.START_DATE);
while (cursor.moveToNext()) {
String name = cursor.getString(nameColumn);
String number = cursor.getString(numberColumn);
String email = cursor.getString(emailColumn);
String birthDay = cursor.getString(bithDayColumn);
Log.d(TAG, "Birthday: " + birthDay);
}
}
In your projection you're limiting your query to rows of MIMETYPE CommonDataKinds.Event.CONTENT_ITEM_TYPE only, so you'll only get birthdays.
You need to ask for emails and phones mimetypes, but note that these additional information will come in separate rows for the same contact.
For example, for contact A that has 2 phones, 3 emails and a birthday, you'll get 6 results in your cursor. So you need to group them all together using the CONTACT_ID field.
Here's simple code to get you started, print the resulting HashMap and you'll get for each contact all his/hers name, emails, phones and birthday:
Map<Long, List<String>> contacts = new HashMap<Long, List<String>>();
String[] projection = {Data.CONTACT_ID, Data.DISPLAY_NAME, Data.MIMETYPE, Data.DATA1, Data.DATA2, Data.DATA3};
// query only emails/phones/events
String selection = Data.MIMETYPE + " IN ('" + Phone.CONTENT_ITEM_TYPE + "', '" + Event.CONTENT_ITEM_TYPE"', '" + Email.CONTENT_ITEM_TYPE + "')";
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(Data.CONTENT_URI, projection, selection, null, null);
while (cur != null && cur.moveToNext()) {
long id = cur.getLong(0);
String name = cur.getString(1); // full name
String mime = cur.getString(2); // type of data (phone / birthday / email)
String data = cur.getString(3); // the actual info, e.g. +1-212-555-1234
String kind = "unknown";
switch (mime) {
case Phone.CONTENT_ITEM_TYPE:
kind = "phone";
break;
case Event.CONTENT_ITEM_TYPE:
kind = "birthday";
break;
case Email.CONTENT_ITEM_TYPE:
kind = "email";
break;
}
Log.d(TAG, "got " + id + ", " + name + ", " + kind + " - " + data);
// add info to existing list if this contact-id was already found, or create a new list in case it's new
List<String> infos;
if (contacts.containsKey(id)) {
infos = contacts.get(id);
} else {
infos = new ArrayList<String>();
infos.add("name = " + name);
contacts.put(id, infos);
}
infos.add(kind + " = " + data);
}
I am using Contact picker library for selecting multiple contacts but if a contact doesn't contain any number and if it is selected then it is showing some null pointer exception in the edit text field. How to remove that message and also how to remove trailing comma. Below is my Code.
try {
int pos = 0;
for (Contact contact : contacts) {
String displayName = contact.getDisplayName();
result.append(displayName + ",");
result.setSpan(new BulletSpan(15), pos, pos + displayName.length() + 1, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
//pos += displayName.length() + 1;
}
}
catch (Exception e) {
result.append(e.getMessage());
}
contactsView.setText(result);
please try to check this code
void getAllContacts() {
ArrayList<String> nameList = new ArrayList<>();
ArrayList<String> numberList = new ArrayList<>();
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER;
String[] list = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone._ID, ContactsContract.Contacts._ID};
Cursor cursor = getContentResolver().query(uri, list, selection, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
cursor.moveToFirst();
if (cursor.moveToFirst()) {
do {
String contactNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
contactNuber.add(contactNumber);
contactsName.add(contactName);
nameList.add(contactName);
numberList.add(contactNumber);
} while (cursor.moveToNext());
cursor.close();
myContacts.put("name", nameList);
myContacts.put("number", numberList);
}
}
I search about read song in android and I see a code from you:
private static ArrayList<SongModel> LoadSongsFromCard() {

String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0"

+ " AND " + MediaStore.Audio.Media.DURATION + " > 60000";
final String[] projection = new String[] {
MediaStore.Audio.Media._ID, //0
MediaStore.Audio.Media.TITLE, //1
MediaStore.Audio.Media.ARTIST, //2
MediaStore.Audio.Media.DATA, //3
MediaStore.Audio.Media.DISPLAY_NAME
};
final String sortOrder = MediaStore.Audio.AudioColumns.TITLE
+ " COLLATE LOCALIZED ASC";
Cursor cursor = null;
try {
// the uri of the table that we want to query
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI; //getContentUriForPath("");
// query the db
cursor = _context.getContentResolver().query(uri,
projection, selection, null, sortOrder);
if (cursor != null) {
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
//if (cursor.getString(3).contains("AwesomePlaylists")) {
SongModel GSC = new SongModel();
GSC.ID = cursor.getLong(0);
GSC.songTitle = cursor.getString(1);
GSC.songArtist = cursor.getString(2);
GSC.path = cursor.getString(3);
// This code assumes genre is stored in the first letter of the song file name
String genreCodeString = cursor.getString(4).substring(0, 1);
if (!genreCodeString.isEmpty()) {
try {
GSC.genre = Short.parseShort(genreCodeString);
} catch (NumberFormatException ex) {
Random r = new Random();
GSC.genre = (short) r.nextInt(4);
} finally {

cursor.moveToNext();

I'm really learning to program for Android, and modify your code for what I needed , but I have trouble understanding when you assign cursor
cursor = _context.getContentResolver () query ( uri , projection , selection , null, sortOrder ) . ;
Part of _context not understand you kindly explain it please.
If your class extends activity you can use this for _context. If not, you need to pass the context from your activity. The first case mentioned would look like this:
// query the db
cursor = this.getContentResolver().query(uri, projection, selection, null, sortOrder);
__
What is Context in Android?
I'm using "Calls.CONTENT_URI" content provider. I already retrived column names, but now i would like to get let's say, ALL names from column name "name" in this content provider.
I have code below:
uri = Calls.CONTENT_URI;
String[] projection = {"name"};
String selection = null;
String[] selectionArgs = null;
String sort = null;
resolver = getContentResolver();
cursor = resolver.query(uri, projection, selection, selectionArgs, sort);
Log.i("TUTORIAL", "counts :"+cursor.getCount());
String s;
cursor.moveToFirst();
for(int x=0; x<cursor.getCount(); x++){
s = cursor.getString(x);
Log.i("TUTORIAL", ""+s);
//cursor.moveToNext();
}
But this retrives only one name. I would like to have list of all names saved in my phone like:
John
Peter
Mark
Suzy
.
.
X
But now i got just one name like:
Peter.
Hope i've been clear enough.
What's the problem? Thanks for help in advance.
I think this would help you
ArrayList<String> nameList = new ArrayList<String>();
String[] projection = {"name"};
String selection = null;
String[] selectionArgs = null;
String sort = null;
resolver = getContentResolver();
cursor = resolver.query(uri, projection, selection, selectionArgs, sort);
Log.i("TUTORIAL", "counts :"+cursor.getCount());
String s;
if(cursor.moveToFirst()) {
do {
nameList.add(cursor.getString(0));
//your code
//s = cursor.getString(x);
Log.i("TUTORIAL", ""+cursor.getString(0));
}while(cursor.moveToNext());
}
you can try this one , it's working for me :
public void readContacts() {
Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
// Get contact id (id)
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
// Get contact name (displayName)
String displayName = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
}
}
cur.close();
}
This is the code.
public class MainActivity extends AppCompatActivity {
SimpleCursorAdapter mAdapter;
MatrixCursor mMatrixCursor;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// The contacts from the contacts content provider is stored in this cursor
mMatrixCursor = new MatrixCursor(new String[] { "_id","name","photo","details"} );

R.layout.lv_layout,

// Getting reference to listview

// Setting the adapter to listview
lstContacts.setAdapter(mAdapter);

I need the most updated image, and I need to select from two different places. How do I do this?
Below is my code, and it returns only from /dcim/camera, not from eye-fi when it should be able to return from both.
private void PopulateDataSource() {
if (_context == null) return;
if(_context.getContentResolver() != null) {
final ContentResolver cr = _context.getContentResolver();
String[] projections = new String[] {
MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATE_TAKEN,
MediaStore.Images.ImageColumns.DATA };
String sortOrder = String.format(
"%s limit 10", Images.ImageColumns.DATE_TAKEN + " DESC");
final String[] selectionArgs = {
getBucketId(Environment.getExternalStorageDirectory().toString() +
"/Eye-Fi"),
getBucketId(Environment.getExternalStorageDirectory().toString() +
"/DCIM/Camera") };
final String selection = MediaStore.Images.Media.BUCKET_ID + " = ?";
try {
// select all images from DataBase and set it in Cursor
SearchCursor = cr.query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projections, selection, selectionArgs, sortOrder);
}
catch (Exception ex) {
Log.e("Cursor failed", ex.getMessage());
}
}
}
Replace your selection string with the following:
final String selection = MediaStore.Images.Media.BUCKET_ID + " IN (?, ?)";
