any one have any clue of this behavior?, please help me if you can :)

The text disappears since the updating of your TextView takes place in onCreate.
#Override
protected void onResume() {
SAVEBTN.setOnClickListener(v -> {
senddata();
});
loaddata();
updateviews();
}
This should do the trick.
Go through the Activity lifecycle to see how this works. But basically moving methods to onResume should work.

SeekBar not working while used in pop up window java android studio

Hi I've been trying to make a pop up window which presents a trackable seekbar as a part of a school project, both parts of the code work alone but when put together the seekbar progress is not tracked (you can move the seekbar but the number won't change), Help would be very appreciated!

// inflate the layout of the popup window
LayoutInflater inflater = (LayoutInflater)
getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = inflater.inflate(R.layout.activity_pop_up, null);
// create the popup window
int width = LinearLayout.LayoutParams.MATCH_PARENT;
int height = 500;
boolean focusable = true; // lets taps outside the popup also dismiss it
final PopupWindow popupWindow = new PopupWindow(popupView, width, height, focusable);
// show the popup window
// which view you pass in doesn't matter, it is only used for the window token
popupWindow.showAtLocation(view, Gravity.BOTTOM, 0, 0);
// dismiss the popup window when touched
popupView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
popupWindow.dismiss();
return true;
}
});

How do I create a fragment template(class with variables and methods, layout) for multiple fragments with the same content?

On the main screen I have 7 buttons (days) and a fragment.
For every day of the week I wanted to generate a fragment with some EditTexts and a ListView, but creating 7 fragments with the same layout and almost the same class content seems too repetitive.
I only did it for Monday and Tuesday.
The only difference between MondayFragment and TuesdayFragment is that in TuesdayFragment I renamed the variable mondayTV to tuesdayTV and in layout I changed the ids of the submit button and the ListView. Also the key for Bundle is different. I don't think it's worth posting it since it's so similar to MondayFragment.
I want to know if it's possible to create a fragment template and use it to generate a fragment for every button of the activity given this code I wrote. There is still a lot to work on when it comes to functionality but I can't get this idea out of my head.

MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button monday = findViewById(R.id.monday_btn),
tuesday = findViewById(R.id.tuesday_btn),
wednesday = findViewById(R.id.wednesday_btn),
thursday = findViewById(R.id.thursday_btn),
friday = findViewById(R.id.friday_btn),

btn.setOnClickListener(v -> {
String contentDescription = btn.getContentDescription().toString();
getSupportFragmentManager().beginTransaction()
.replace(R.id.daysfragment, new DayFragment(contentDescription))
.addToBackStack(null)
.commit();
});
}
}
In MainActivity openFragment() method takes a Button parameter and with that Button and sets onClickListener to that Button. When you click any Button it gets content description from that Button and passing it to Fragment and opens that Fragment with that content description.

How can I send two different text intents to the same textview from one activity to another?

I've read many answers and I cannot find where I'm going wrong with my code. I want to have 2 buttons on my first activity. When I click button1 or button2 I want text held within that specific string resource to appear on the textview of activity two. I am able to populate one of the strings, but it will not separate them depending on which button I click.

I think You have to make two separate functions. Why You add 2 intents in one function? You only want to make one intent and pass one string. Also, you can add tag to button 1 = But1 and button 2 = But2. Just add to XML layout android:tag="But1" to both buttons.
'
public void launchSecondActivity(View view) {
String arg = null;
if (view.getTag().equals("But1"))
{
arg = mButtonMainText.getText().toString();
}
else if (view.getTag().equals("But2"))
{
arg = mButtonSecondText.getText().toString();
}
Intent intent = new Intent(this, PassageActivity.class);
intent.putExtra(EXTRA_MESSAGE, arg);
startActivity(intent);

i expected that when i write admin admin for username and password, it saved it and for the second time i open the app it skip that login page but its not work and show the login page again

My app does not load an activity on the device

My android app links to a new activity to allow a user to create their profile and save the strings they use to a firebase database. However, the activity loads but is blank as shown below. This issue only seemed to arise after I added functionality to save user data to firebase.

The method that is called to send the user to the create profile activity
private void LoginUser(){
setEmailStr(email.getText().toString().trim());
String Password = password.getText().toString().trim();
mAuth.signInWithEmailAndPassword(emailStr, Password)
.addOnCompleteListener(this, new
OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()){
currentUser = mAuth.getCurrentUser();
finish();
Toast.makeText(ActivityLoginEmail.this, "Create
Activity", Toast.LENGTH_SHORT).show();
setCurrent_user_db(false);
startActivity(new Intent(ActivityLoginEmail.this,
CreateProfileActivity.class));
}else {
setCurrent_user_db(true);
Toast.makeText(ActivityLoginEmail.this, "couldn't login",
Toast.LENGTH_SHORT).show();
}
}
});
}
}
EDIT:After changing the xml file to a simple one with just a single button and adding a toast command to print if the activity loads nothing happens. Therefore the problem is most likely not within the xml files.
EDIT2:I found the solution by removing the PersistableBundle parameter from my oncreate method. Not exactly sure what this does to begin with if anyone would like to elaborate.
public class CreateProfileActivity extends AppCompatActivity {
public static final String INTEREST_KEY = "interest";
public static final String NAME_KEY = "name";
private DocumentReference mDocRef = RegisterActivity.getmDocRef();
private Button createBtn;
public void onCreate( Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.create_profile_layout);
Toast.makeText(this, "Create Activity", Toast.LENGTH_SHORT).show();
EditText interestsView = (EditText) findViewById(R.id.interests);
EditText nameView = (EditText) findViewById(R.id.profile_name);
String interests = interestsView.getText().toString();
String name= nameView.getText().toString();
Map<String, Object> dataToSave = new HashMap<>();
mDocRef = FirebaseFirestore.getInstance().document("users/" +
ActivityLoginEmail.getEmailStr() + "/profileInfo");
dataToSave.put(INTEREST_KEY, interests);
dataToSave.put(NAME_KEY, name);
mDocRef.set(dataToSave);
createBtn = (Button) findViewById(R.id.createProfileBtn);
createBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(CreateProfileActivity.this, Profile.class);
startActivity(intent);
}
});
}
}
try by moveing finish() to the bottom of this condition
if (task.isSuccessful()){
currentUser = mAuth.getCurrentUser();
Toast.makeText(ActivityLoginEmail.this, "Create
Activity", Toast.LENGTH_SHORT).show();
setCurrent_user_db(false);
startActivity(new Intent(ActivityLoginEmail.this,
CreateProfileActivity.class));
finish();
}
