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);

setOnClickListener not working in fragment Android

I am trying to apply a setOnClickListener on an EditText View in a Fragment and for some reason, It is not working, the code in the listener doesn't execute when I click on the EditText.
The fragment xml:

The fragment code:

#Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.add_payment_fragment, container, false);
view.findViewById(R.id.add_pay_time).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
}
});
return view;
}

Edit text needs focus to call onClick().
Solution 1
request focus when you set listener:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
}
});
editText.requestFocus(); //request focus
Solution 2
set on touch listener:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (MotionEvent.ACTION_DOWN == event.getAction())
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
return false;
}
});
Solution 3
you can use onClickListener and onFocusChangeListener together:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showToast();//call your method
}
});
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus)
showToast();//call your method
}
});

EditText edText = view.findViewById(R.id.add_pay_time);
edText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getActivity(), "aaaa", Toast.LENGTH_LONG).show();
}
});

Use getActivity().getApplicationContext() instead

java.lang.StringIndexOutOfBoundsException: error in Android

while I was testing my app using the virtual emulator (don't have a valid device where I can test), I found out a bug. That's the java.lang.StringIndexOutOfBoundsException: length=0; index=2 error, and it pops out when I click on an EditText and try to write in it. The EditText is set to appear when another button is clicked. Here is the XML:

And here it is the Java class:

#Override

setContentView(R.layout.activity_allergie);

btn_no = (Button) findViewById(R.id.btn_allergia_no);
et_allergia = (EditText) findViewById(R.id.allergia_si);
btn_avanti = (Button) findViewById(R.id.btn_avanti3);
et_allergia.setVisibility(View.INVISIBLE);
btn_no.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view)
{
btn_no.setBackground(getResources().getDrawable(R.drawable.round_shape_clicked_btn)); //cambia il colore di base
}
});
btn_si.setOnClickListener(new View.OnClickListener() { //cambia il colore di base e rende visibile l'edit text
#Override
public void onClick(View view)
{
btn_si.setBackground(getResources().getDrawable(R.drawable.round_shape_clicked_btn)); //cambia il colore di base
et_allergia.setVisibility(View.VISIBLE);
}
});
btn_avanti.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view)
{
Intent intent = new Intent(allergie.this, Preferenze.class);
startActivity(intent);
}
});
}

You are getting error Because, You have set property 'textAllCaps' in EditText. This property is mostly used for TextView.
Remove This Property and try again.

How to wrap alertdialog in android?

Here is some of my implementation in the MainActivity.java:
AlertDialog.Builder mBuilder = new AlertDialog.Builder(MainActivity.this);
View mView = getLayoutInflater().inflate(R.layout.activity_dialog, null);
.....
mBuilder.setView(mView);
final AlertDialog dialog = mBuilder.create();
dialog.show();

Try Creating a dialog like this. this works perfect and then right away your dialog logic is seperated from you activity logic
public class CustomDialog extends Dialog implements
android.view.View.OnClickListener {
public Activity c;
public CustomDialog d;
public Button yes, no;
public CustomDialog(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.dialog_layout);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//dosomething
}
});
}
}

Hope it is not correct to wrap the content of dialog as it might disrupt the view in tablets and larger devices.
Anyhow, basing upon your requirement.. hope this link works

EditText is declared and LogCat is still giving nullpointerexception

Ok, so I am getting a nullpointerexception in logcat when I am running my app, however I looked at other StackOverflow questions that were similar to mine and found that I had done everything right, so where is my error coming from?
here is my MainActivity:
public double inchSnow, durationStorm, peakSnow, peakTime, finalSnow, windSpeed, snowGround, result, avgSnow;
EditText inSnow, durnStorm, pSnow, pTime, fSnow, wSpeed, sGround;
protected void onCreate(Bundle savedInstanceState) {
final AlertDialog.Builder invalidNumber = new AlertDialog.Builder(actContext);
invalidNumber.setTitle("Blank Field!");
invalidNumber.setMessage("Seems like a field has been left blank, can you fix it?");
invalidNumber.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.cancel();
}
});
inSnow = (EditText) findViewById(R.id.inchesSnow);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getZip = (Button) findViewById(R.id.calculate);
final Intent intent = new Intent(this, com.boreas.snowdaycalculator.result.class);
getZip.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try{
inchSnow = new Integer(inSnow.getText().toString()).intValue();
}catch (NumberFormatException ex){
final AlertDialog alertDialog = invalidNumber.create();
invalidNumber.show();
}
Intent myIntent = new Intent(MainActivity.this, result.class);
myIntent.putExtra("inchSnow",inchSnow);
startActivity(myIntent);
}

Anyone have any ideas on what I am doing wrong? Thanks.

You need to place
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
before all other calls in method. findViewById() will return null until you set the content view. And more importantly, super.onCreate(savedInstanceState) will create the activity to work with.

Put the line:
inSnow = (EditText) findViewById(R.id.inchesSnow);
after the line:
setContentView(R.layout.activity_main);
