Saving edit to listview android studio

Saving edit to listview android studio - java

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();
}
});

Sending Data from Alert Dialog to New Activity

I am new to Android development and I am trying to send data via EditText to TextView from an alert dialog inflated in the MainActivity to a different activity (NewGame.java). I have tried intent.putExtra (see below) however I am getting null pointer exceptions as it seems I cannot access the views from the dialog layout xml file.
I know there are a few other ways to create an alert dialog so perhaps this way is not best for what i am trying to achieve?
MainActivity.java
public class MainActivity extends AppCompatActivity {
Button newGame, prevGames, newSquad, savedSquads;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
newGame = findViewById(R.id.buttonNewGame);
newGame.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
LayoutInflater inflater= getLayoutInflater();
builder.setView(R.layout.new_game_dialog);
final View myView= inflater.inflate(R.layout.new_game_dialog, null);
EditText enterTeam1, enterTeam2, enterDate, enterTime, enterLocation;
enterTeam1 = myView.findViewById(R.id.etTeam1);
enterTeam2 = myView.findViewById(R.id.etTeam2);
enterDate = myView.findViewById(R.id.etDate);
enterTime = myView.findViewById(R.id.etTime);
enterLocation = myView.findViewById(R.id.etLocation);
builder.setTitle("New Game")
.setCancelable(true)
.setPositiveButton("Start", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(MainActivity.this, NewGame.class);
intent.putExtra("TEAM1", enterTeam1.getText().toString());
intent.putExtra("TEAM2", enterTeam2.getText().toString());
intent.putExtra("DATE", enterDate.getText().toString());
intent.putExtra("TIME", enterTime.getText().toString());
intent.putExtra("LOCATION", enterLocation.getText().toString());
startActivity(intent);
}
})
.setNegativeButton("Cancel", null);
builder.create();
builder.show();
}
});
NewGame.java
public class NewGame extends AppCompatActivity {
TextView team1, team2, date, time, location;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_game);
team1 = findViewById(R.id.tvTeam1);
team2 = findViewById(R.id.tvTeam2);
date = findViewById(R.id.tvDate);
time = findViewById(R.id.tvTime);
location = findViewById(R.id.tvLocation);
team1.setText(getIntent().getStringExtra("TEAM1"));
team2.setText(getIntent().getStringExtra("TEAM2"));
date.setText(getIntent().getStringExtra("DATE"));
time.setText(getIntent().getStringExtra("TIME"));
location.setText(getIntent().getStringExtra("LOCATION"));
}

I believe you are having this problem because you are actually inflating 2 views. And referencing the wrong one when you use findById.
LayoutInflater inflater= getLayoutInflater();
builder.setView(R.layout.new_game_dialog);
final View myView= inflater.inflate(R.layout.new_game_dialog, null);
should look like this
LayoutInflater inflater= getLayoutInflater();
final View myView= inflater.inflate(R.layout.new_game_dialog, null);
builder.setView(myView);

How to handle multiple intents on same activity?

Okay, I simply want to have multiple intents passing data into a single activity which will summarise all the user inputs into a nice easy to read form.
This is for a mock up school application form.
The following code works fine but will produce two activities: One showing the student's gender and one showing the students name. How to get it to display both in the same activity? Pulling my hair out over this!!

startActivity(genderIntent);
}
}
Java code of reviewScreenActivity:
public class reviewScreenActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_review_screen);
//Student Full Name reciever
Bundle sfnBundle = getIntent().getExtras();
String studentFullName = sfnBundle.getString("studentFullName");
if (studentFullName != null) {
TextView sfn = (TextView) findViewById(R.id.studentFullNameReviewScreen);
sfn.setText(studentFullName);
}
else {
TextView sfn = (TextView) findViewById(R.id.studentFullNameReviewScreen);
sfn.setText("Not showing right!");
}
//Student Gender Reciever
Bundle sgBundle = getIntent().getExtras();
String studentGender = sgBundle.getString("studentGender");
TextView sg = (TextView)findViewById(R.id.studentGenderReviewScreen);
sg.setText(studentGender);
}
}

Well you have a lot of mistakes such as incorrect class and method names.
You can pass as many as you want extra in one intent.
public void createCaregiverInfoSplash(View v){
//Send Student Full Name
EditText studentFullNameInput = (EditText) findViewById(R.id.studentFullNameInput);
String studentFullName = studentFullNameInput.getText().toString();
Spinner genderSpinner = (Spinner) findViewById(R.id.genderSpinner);
String studentGender = genderSpinner.getSelectedItem().toString();
Intent reviewIntent = new Intent(studentInfoActivity.this, reviewScreenActivity.class);
reviewIntent.putExtra("studentFullName", studentFullName);
reviewIntent.putExtra("studentGender", studentGender);
startActivity(studentIntent);
}

MaterialEditText is an EditText
public class MaterialEditText extends AppCompatEditText {
it can not contain any widgets. In your layout you have
<com.rengwuxian.materialedittext.MaterialEditText
android:id="#+id/usernameTIL"
android:layout_width="251dp"
android:layout_height="46dp"
android:layout_marginStart="8dp"
android:layout_marginTop="12dp"
android:layout_marginEnd="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.527"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/textView">
<com.rengwuxian.materialedittext.MaterialEditText
android:layout_width="268dp"
android:layout_height="36dp"
android:hint="username" />
</com.rengwuxian.materialedittext.MaterialEditText>
a MaterialEditText containing another MaterialEditText, which is causing your app to crash for ClassCastException

According to this library's sample code, you must cast your MaterialEditText to EditTextlike this:
usernameTIL = (EditText) findViewById(R.id.usernameTIL);
passwordTIL = (EditText) findViewById(R.id.passwordTIL2);

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

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));

How to get value from edit text and display it in a textview in another activity

I have been pulling my hair out for the last 4 hours trying to find out how to do this.
I have checked SO for other questions but found nothing good.
I am an intermediate programmer and would be very appreciative if your comments and answers were written in a way that I can understand.
I want to be able to take the text that the user enters into the #+id/location Edittext box on the InputPage activity and display it in the #+id/ListName TextView on the InputPage2 activity when the button on the InputPage activity is pressed.
InputPage java code
public class InputPage extends Activity {
public String name;
public InputPage() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_input_page );
Button button = (Button)findViewById(R.id.addButton);
}
public InputPage(String name) {
this.name = name;
}
public String getName() {
return name;
}
public String name(String name){
this.name = name;
EditText editText = (EditText)findViewById(R.id.location);
String value = editText.getText().toString();
return value;
}
public void toInputScreen2(View view) {
Button button = (Button) findViewById(R.id.button2);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent2 = new Intent(InputPage.this, InputPage2.class);
startActivity(intent2);
}
});
}
}

Any help is appreciated .

You can pass data between activities like this
Intent intent = new Intent(activity2.this, activity1.class);
intent.putExtra("message", message);
startActivity(intent);
