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.

Create DayFragment and layout only for one day. Pass extra information for Fragment and handle situations for different days with that extra information (in your case it looks like only String from bundle is different).

Use constructor for passing information.
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),
saturday = findViewById(R.id.saturday_btn),
sunday = findViewById(R.id.sunday_btn);
openFragment(monday);
openFragment(tuesday);
openFragment(wednesday);
openFragment(thursday);
openFragment(friday);
openFragment(saturday);
openFragment(sunday);
}
private void openFragment(Button 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);
}

My app keeps on crashing and I am not able to see what the problem is [duplicate]

Closed 3 years ago.
This is my code. Please check.. When I execute it the app crashes. So app was fine before, but I added validation to the form and since then as soon as the app run it crashes. I have used https://www.simplifiedcoding.net/android-form-validation-tutorial/ for adding awsomeform and so I have also made some changes to the strings.xml file. Please check this once too. It was fine before and I could access the file pretty easily.
This is the error I get on Android studio when I try to run the app and the app installs, launches and then crashes.
This is my mainactivity code. I believe something is going on with the implements part and the code i.e. import.com.google.common.collect.range is also unused

Saving edit to listview android studio

I have a list view of restaurants with 4 different strings: Name, Address, description and tags.
When I click a restaurant it leads me to my detailsActivity.java where I let user edit the name, address, description and tags, and then user can save the edited info to be stored in the list view.
So far when I click save it will only save the data for Name... Address, description and tag strings are not saved with new information.
Here is my code :
public class DetailsActivity extends AppCompatActivity {
private int pos;
//RATE RESTAURANT BUTTON
RatingBar ratingbar1;
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
Intent i = getIntent();
String name = i.getStringExtra("name");
final String address = i.getStringExtra("address");
String description = i.getStringExtra("description");
String tags = i.getStringExtra("tags");
pos = i.getIntExtra("position", -1); //-1 means not set
EditText ename = findViewById(R.id.editName);
EditText eaddress = findViewById(R.id.editAddress);
EditText edescription = findViewById(R.id.editDescription);
EditText etags = findViewById(R.id.editTags);
ename.setText(name);
eaddress.setText(address);
edescription.setText(description);
etags.setText(tags);
findViewById(R.id.btnSave).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = getIntent();
EditText ename = findViewById(R.id.editName);
EditText eaddress = findViewById(R.id.editAddress);
EditText edescription = findViewById(R.id.editDescription);
EditText etags = findViewById(R.id.editTags);
String name = ename.getText().toString();
String address = eaddress.getText().toString();
String description = edescription.getText().toString();
String tags = etags.getText().toString();
i.putExtra("name", name);
i.putExtra("address", address);
i.putExtra("description", description);
i.putExtra("tags", tags);
i.putExtra("position", pos);
setResult(RESULT_OK, i);
finish();
}
});

How to open a new activity on click of textview in android?

I am new to android programming world, I have designed as a layout with username, password AS edittext control and "forgot password" as textview control, on click/tap of "forgot password", I want to open a new activity.
This is what I am trying, looking forward for your help.
My Application's xml and java code is mentioned below.

Login.java
public class Login extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
final TextView tvForgotPwd = (TextView) findViewById(R.id.txtVwForgetPassword);
tvForgotPwd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(Login.this, "you clicked me", Toast.LENGTH_SHORT).show();
Intent myIntent = new Intent(view.getContext(),PatientSearch.class);
startActivityForResult(myIntent, 0);
}
});
final Button btnRegister = (Button) findViewById(R.id.btnRegister);
btnRegister.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(),MainActivity.class);
startActivityForResult(myIntent,0);
}
});

Even though this question has been asked so many times, I decided to answer anyway. This will work:
tvForgotPwd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(Login.this, PatientSearch.class);
startActivity(myIntent);
}
});

In your onCreate() method, set an OnClickListener callback on your TextView. In the callback, use an Intent to start the desired activity.
Here is an exemple of code:
yourTextView= (TextView) findViewById(R.id.txtVwForgetPassword);
yourTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setData(Uri.parse("https://youraddress.com"));
startActivity(intent);
}
});

Probably it is necessary to try a method
startActivity (new Intent (Activity.this, Open Activity.class));
