How to send a value from TextView to RecyclerView in another Activity

I'm trying to send a value from TextView to RecyclerView (in an another Activity).
MainActivity.class
There is i want to use a method onClickYes for send each of word to my recyclerView in an another activity.
public class MainActivity extends AppCompatActivity {
TextView display, progress;
private List<String> worldList;
private ArrayList<RecyclerItems> recyclerItems;
private WordDataBase wordDatabaseForYes;
int counter = 1;
int i = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
display = findViewById(R.id.dispalay);
progress = findViewById(R.id.progress);
recyclerItems = new ArrayList<>();
worldList = new ArrayList<>();
worldList.add("cat");//i want to display this word firstly
worldList.add("dog");//it after click
worldList.add("monkey");//after it
worldList.add("bird");//after it
worldList.add("fish");//etc
worldList.add("home");//etc
worldList.add("car");//etc
}
public void onClickYes(View view) {
if (i >= worldList.size()) return;
display.setText(worldList.get(i));
progress.setText(counter + "");
//заполняем наш recyclerView
//Intent intent = new Intent(MainActivity.this, YesActivity.class);
//intent.putExtra("word", user + ", вам передали: " + gift);
//startActivity(intent);
i++;
counter++;
}
public void onClickNo(View view) {
Toast.makeText(this, "Size is " + worldList.size(), Toast.LENGTH_SHORT).show();
//recyclerItems.add(new RecyclerItems(worldList.get(i)));
i = 0;
counter = 0;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
Intent intent;
switch (item.getItemId()) {
case R.id.yes:
recyclerItems.add(new RecyclerItems(worldList.get(i)));
intent = new Intent(MainActivity.this, YesActivity.class);
startActivity(intent);
break;
case R.id.no:
intent = new Intent(MainActivity.this, NoActivity.class);
startActivity(intent);
break;
case R.id.about:
Toast.makeText(this, "By SaturnPRO", Toast.LENGTH_SHORT).show();
//openDialogAbout
break;
}
return true;
}
}
My Second Activity
public class YesActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private RecyclerView.Adapter adapter;
private RecyclerView.LayoutManager layoutManager;
ArrayList<RecyclerItems> yesWordList;
private WordDataBase wordDatabaseForYes;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
yesWordList = new ArrayList<>();
recyclerView = findViewById(R.id.rvYes);
recyclerView.setHasFixedSize(true);
adapter = new RecyclerViewAdapter(yesWordList);
layoutManager = new LinearLayoutManager(this);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(layoutManager);
}
}
Also i have an Adapter but i couldn't show it here.
How can i do it? enter code here Please help.

Send the word in intent extras:
case R.id.yes:
recyclerItems.add(new RecyclerItems(worldList.get(i)));
intent = new Intent(MainActivity.this, YesActivity.class);
intent.putExtra("key", worldList.get(i));
startActivity(intent);
break;
In your second activity:
String name = intent.getStringExtra("key");

You can make the wordList a static member. Then you can access it in your adapter.

I'm using the firebaseRecyclerAdaper on a fragment and i want to open an item from de populated list from firebase and send the data to a new fragment. Can u guys tell me please how can i start the FragmentDetail from the onCLickListener on FragmentAllPosts and pass the PostModel parameter to it?

I'd suggest a read on the documentation. Passing data between two activities should be done via interfaces.
As suggested by the official site

Android Save spinner state in onCreate, and Activity onResume

I am currently facing 2 problems, the spinner state is not saving and when I am on the InformationActivity the spinner is reset. I have used the information on other posts but it doesnt seem to help.
At the moment I cant use finish(); in my onBackPressed(); on InformationActivity because it goes back to the ScannerView as I am Implementing the ZXing library. How could I save the Spinner state and also stop the program from crashing onBackPressed when I am on HomeActivity.
Thanks.
HomeActivity:
public class HomeActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener{
private FirebaseAuth firebaseAuth;
private Button buttonLogout;
private ZXingScannerView scannerView;
private final int permission_code = 1;
String [] selectedProfile;
Spinner spinner;
ArrayAdapter<CharSequence> adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
firebaseAuth = FirebaseAuth.getInstance();
if(firebaseAuth.getCurrentUser() == null){
finish();
startActivity(new Intent(this, MainActivity.class));
}
FirebaseUser user = firebaseAuth.getCurrentUser();
if (savedInstanceState != null) {
spinner.setSelection(savedInstanceState.getInt("yourSpinner", 0));
// do this for each of your text views
}
else {
//android spinner to select profile
spinner = (Spinner) findViewById(R.id.spinnerProfiles);
adapter = ArrayAdapter.createFromResource(this, R.array.restrictions, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_list_item_1);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(this);
}
}
//opens camera when button is pressed
public void scanBarcode(View view) {
//check if user given app camera permissions
if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, permission_code);
}
//opens camera
scannerView = new ZXingScannerView(this);
scannerView.setResultHandler(new ZXingScannerResultHandler());
//stops camera and scannerview
setContentView(scannerView);
scannerView.startCamera();
}
//selects an item from the spinner and passes it to InformationActivity
#Override

Toast.makeText(this, "Permission Granted", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Permission Denied", Toast.LENGTH_LONG).show();
}
}
//go back to home after permissions accepted
Intent intent = new Intent(getApplicationContext(), HomeActivity.class);
startActivity(intent);
scannerView.stopCamera();
}
//goes back to homepage when back button is pressed
#Override
public void onBackPressed() {
setContentView(R.layout.activity_home);

//stops the camera on pause
#Override

}
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_information);

barcodeView.setText(getIntent().getExtras().getString("BarcodeString"));
TextView profileView = (TextView) findViewById(R.id.tvProfile);

profileView.setText(selectedProfile[0]);

To Save Spinner posotion in sharedpreference :
int userChoice = spinner.getSelectedItemPosition();
SharedPreferences sharedPref = getSharedPreferences("FileName",0);
SharedPreferences.Editor prefEditor = sharedPref.edit();
prefEditor.putInt("userChoiceSpinner",usersChoice);
prefEditor.commit();
Get Data from sharedpreferences :
SharedPreferences sharedPref = getSharedPreferences("FileName",MODE_PRIVATE);
int spinnerValue = sharedPref.getInt("userChoiceSpinner",-1);
if(spinnerValue != -1) {
// set the selected value of the spinner
spinner.setSelection(spinnerValue);
}
Also look into this :
One Another Example to save : https://stackoverflow.com/a/29527936/8448886
SharedPreference Tutorial :https://www.journaldev.com/9412/android-shared-preferences-example-tutorial

when you select any item from spinner at that time get that selected item and store that position and after when you come back to activity load spinner first, compare that item with array items and get position of that item then set that position to spinner i think this way you get exact selection of that item into spinner.

onActivityResult not called when I will finish selected image

I want to add an image from device to the app.
I will use solution of David Manpearl at this openImageIntent.
My code looks fine but when I run the app and select the image in the app, but the problem is the onActivityResult when I finish selecting the image. Please see my code and advise me on what I'm doing wrong. Thank for any suggestion.
Update Info: This Fragment is parent of another Fragment it's name "EventFragment" because I have use FragmentTabHost in EventFragment to display EventAdd class fragment and I have MainActivity it's a ActionBarActivity this is a main of activity when application started. When I click EventFragment menu from MainActivity it will go to EventFragment and EventAdd it's here in FragmentTabHost . Let's see the code:

In your host activity (MainActivity.java) you need to do:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
}

Issue with setting and opening fragments in Android App

I am having a issue, as my app is crashing instead of opening the fragments. I have a ListActivity, that takes you to another activity; and in that other activity, there are two fragments. The ListActivity is expecting a result from one of the fragments.
My code was working prior to adding the fragments! However the fragments are no longer showing up and the app closes...does anyone possibly know what my issue could be? And any advice on how to take this issue? I sincerely appreciate all and any help, thank you! My code is below.
The ListActivity.java:
public class LyricList extends ListActivity {
private static final int ACTIVITY_CREATE=0;
private static final int ACTIVITY_EDIT=1;
private static final int INSERT_ID = Menu.FIRST;
private static final int DELETE_ID = Menu.FIRST + 1;
private LyricsDbAdapter mDbHelper;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lyriclist);
mDbHelper = new LyricsDbAdapter(this);
mDbHelper.open();
fillData();
registerForContextMenu(getListView());
}
private void fillData() {
Cursor lyricsCursor = mDbHelper.fetchAllLyrics();
startManagingCursor(lyricsCursor);
String[] from = new String[]{LyricsDbAdapter.KEY_TITLE};
int[] to = new int[]{R.id.text1};
SimpleCursorAdapter lyrics =
new SimpleCursorAdapter(this, R.layout.lyrics_row, lyricsCursor, from, to);
setListAdapter(lyrics);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, INSERT_ID, 0, R.string.menu_insert);
return true;
}
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
switch(item.getItemId()) {
case INSERT_ID:
createLyric();
return true;
}
return super.onMenuItemSelected(featureId, item);
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.add(0, DELETE_ID, 0, R.string.menu_delete);
}
#Override
public boolean onContextItemSelected(MenuItem item) {
switch(item.getItemId()) {
case DELETE_ID:
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
mDbHelper.deleteLyric(info.id);
fillData();
return true;
}
return super.onContextItemSelected(item);
}
private void createLyric() {
Intent i = new Intent(this, NextActivity.class);
startActivityForResult(i, ACTIVITY_CREATE);
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Intent i = new Intent(this, NextActivity.class);
i.putExtra(LyricsDbAdapter.KEY_ROWID, id);
startActivityForResult(i, ACTIVITY_EDIT);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
fillData();
}
}
The other activity class that should be opening via the listActivity:
public class NextActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_next);
ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
Tab one = actionBar.newTab().setText("Lyric Editor");
Tab two = actionBar.newTab().setText("Loops");
one.setTabListener(new MyTabListener(new LyricEditorFragment()));
two.setTabListener(new MyTabListener(new LoopsFragment()));
actionBar.addTab(one);
actionBar.addTab(two);
}
public class MyTabListener implements TabListener{
Fragment fragment;
public MyTabListener(Fragment f){
fragment = f;
}
#Override
public void onTabReselected(Tab arg0, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override
public void onTabSelected(Tab arg0, FragmentTransaction ft) {
// TODO Auto-generated method stub
ft.replace(R.id.frame1, fragment);
}
#Override
public void onTabUnselected(Tab arg0, FragmentTransaction ft) {
// TODO Auto-generated method stub
ft.remove(fragment);
}
}
}
Not sure if you want to see the fragment class, but here is this just incase:
public class LyricEditorFragment extends Fragment {
private EditText mTitleText;
private EditText mBodyText;
private Long mRowId;
private LyricsDbAdapter mDbHelper;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDbHelper = new LyricsDbAdapter(getActivity());
mDbHelper.open();
mTitleText = (EditText) getView().findViewById(R.id.title);
mBodyText = (EditText) getView().findViewById(R.id.body);
Button confirmButton = (Button) getView().findViewById(R.id.confirm);
mRowId = (savedInstanceState == null) ? null :
(Long) savedInstanceState.getSerializable(LyricsDbAdapter.KEY_ROWID);
if (mRowId == null) {
Bundle extras = getActivity().getIntent().getExtras();
mRowId = extras != null ? extras.getLong(LyricsDbAdapter.KEY_ROWID)
: null;
}
populateFields();
confirmButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
getActivity().setResult(Activity.RESULT_OK);
getActivity().finish();
}
});
}
private void populateFields() {
if (mRowId != null) {
Cursor lyric = mDbHelper.fetchLyric(mRowId);
getActivity().startManagingCursor(lyric);
mTitleText.setText(lyric.getString(
lyric.getColumnIndexOrThrow(LyricsDbAdapter.KEY_TITLE)));
mBodyText.setText(lyric.getString(
lyric.getColumnIndexOrThrow(LyricsDbAdapter.KEY_BODY)));
}
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
saveState();
outState.putSerializable(LyricsDbAdapter.KEY_ROWID, mRowId);
}
#Override
public void onPause() {
super.onPause();
saveState();
}
#Override
public void onResume() {
super.onResume();
populateFields();
}
private void saveState() {
String title = mTitleText.getText().toString();
String body = mBodyText.getText().toString();
if (mRowId == null) {
long id = mDbHelper.createLyric(title, body);
if (id > 0) {
mRowId = id;
}
} else {
mDbHelper.updateLyric(mRowId, title, body);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
//return super.onCreateView(inflater, container, savedInstanceState);
View view = inflater.inflate(R.layout.activity_lyriceditor, container, false);
return view;
}
}

The problem is that you are getting a View from the activity which will return null.. you need to create/inflate the view from the onCreateView..
