I would like to show an error message within an alert dialog box for password reset, however no error message shows inside the dialog pop up.
Alert Dialog Box
When clicking "Reset" the dialog box will close. However, entering in a valid email does show the toast message "Reset Email Sent"
The validations are 1) leaving the email address empty , 2)not giving a proper email
Login.java
//onclick for forgot password
forgotPText = findViewById(R.id.forgotPassText);
forgotPText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//start alert dialog
View view = inflater.inflate(R.layout.reset_popup,null);
reset_alert.setTitle("Forgot Password ?")
.setMessage("Enter Email For Password Reset Link.")
.setPositiveButton("Reset", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//validate the email address is not empty or not valid email
EditText email = view.findViewById(R.id.reset_popup_Email);
String emailChar = email.getText().toString();
if (email.getText().toString().isEmpty()){
email.setError("Required Field!");
return;
}
if(!Patterns.EMAIL_ADDRESS.matcher(emailChar).matches()){
email.setError("Please provide valid email!");
email.requestFocus();
return;
}
//send reset link
firebaseAuth.sendPasswordResetEmail(email.getText().toString())
.addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
//FirebaseUser user = firebaseAuth.getCurrentUser();
//updateUI(user);
Toast.makeText(LoginActivity.this
, "Reset Email Sent", Toast.LENGTH_SHORT).show();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(LoginActivity.this, e.getMessage(),
Toast.LENGTH_SHORT).show();
}
});
}
}).setNegativeButton("Cancel",null)
.setView(view)
.create().show();
}
});
Use this code:
forgotPText.setOnClickListener(new View.OnClickListener() {

LayoutInflater inflater = getLayoutInflater();

I have a code which inflates a custom layout inside an Alert Dialog.
The Custom Layout consists of an EditText and a Button. What is the correct way to display the EditText String inside a Toast by clicking the Button ?
I have tried the below code but it doesn't seem to work.
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setPositiveButton("Fetch", (dialog, which) -> {
}).setNeutralButton("Cancel", (dialog, which) -> {
});
final AlertDialog dialog = builder.create();
LayoutInflater inflater = getLayoutInflater();
View dialogLayout = inflater.inflate(R.layout.custom_layout, null);
dialog.setView(dialogLayout);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.show();
dialog.setOnShowListener(d -> {
EditText dialogNameEditText = dialog.findViewById(R.id.dialog_name_edittext);
Button dialogPrintButton = dialog.findViewById(R.id.dialog_print_button);
dialogPrintButton.setOnClickListener(v1 -> {
Toast.makeText(
TestActivity.this,
dialogNameEditText.getText().toString(),
Toast.LENGTH_SHORT
).show();
});
});
custom_layout.xml file
<LinearLayout

Originally answered
Create a separate function for toast
public void show_toast(){
Toast.makeText(
TestActivity.this,
dialogNameEditText.getText().toString(),
Toast.LENGTH_SHORT
).show();
}
and in onclicklistener call it
dialog.setOnShowListener(d -> {
EditText dialogNameEditText = dialog.findViewById(R.id.dialog_name_edittext);
Button dialogPrintButton = dialog.findViewById(R.id.dialog_print_button);
dialogPrintButton.setOnClickListener(v1 -> {
show_toast();
});
});
Try this simple code. it will work.
Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.custom_layout);
EditText dialogNameEditText = dialog.findViewById(R.id.dialog_name_edittext);
Button dialogPrintButton = dialog.findViewById(R.id.dialog_print_button);
dialogPrintButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,dialogNameEditText.getText(), Toast.LENGTH_SHORT).show();
}
});
dialog.show();

The exception is caused by this line:
final String Notes = txtNotes.getText().toString();
As described in the reason, the txtNotes member is null, which means that the binding did not work (probably the view with txtnotes id was not found).
From what I see, you call ButternKnife.bind() for the activity which has the activity_show_the_post layout as content view. But the view with txtnotes id is actually in the create_comment layout, of which ButterKnife knows nothing about, and doesn't even exist at that time. Thus, the binding fails, no reference to txtnotes is created and you later get a NPE.
You need to bind the views for create_comment.xml too
view = getLayoutInflater().inflate(R.layout.create_comment,null);
Butterknife.bind(view,this);
alert.setCancelable(false);
alert.setView(view);
final AlertDialog dialog = alert.create();
I'm trying to create an Dialog to show an introduction message in my application, with a "Don't show this again" CheckBox below it.
I do not know how to make code.
<MainActivity.java>
#Override
protected void onStart()
{
super.onStart();
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.dialog);
dialog.setTitle("Warning!");
Button button = (Button) dialog.findViewById(R.id.okay);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
dialog.dismiss();
}
});
dialog.show();
}

Hai sorry for late answer but in your problem
you can easily solve it using shared preferences
heres the link:
and the code:
AlertDialog.Builder adb= new
AlertDialog.Builder(this);
LayoutInflater adbInflater =
LayoutInflater.from(this);
View eulaLayout = adbInflater.inflate
(R.layout.activity_main, null);
check = (CheckBox)
eulaLayout.findViewById(R.id.skip);
adb.setView(eulaLayout);
adb.setTitle("Example:");
adb.setMessage(Html.fromHtml("Type your
text here: "));
adb.setPositiveButton("Ok", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface
dialog, int which) {
String checkBoxResult = "NOT
checked";
if (check.isChecked())
checkBoxResult = "checked";
SharedPreferences settings =
getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor
editor = settings.edit();
editor.putString("noshow",
checkBoxResult);
// Commit the edits!
// sunnovalthesis();
editor.commit();
return;
} });
adb.setNegativeButton("Cancel", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface
dialog, int which) {
String checkBoxResult = "NOT
checked";
if (check.isChecked())
checkBoxResult = "checked";
SharedPreferences settings =
getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor =
settings.edit();
editor.putString("noshow",
checkBoxResult);
// Commit the edits!
// sunnovalthesis();
editor.commit();
return;
} });
SharedPreferences settings =
getSharedPreferences(PREFS_NAME, 0);
String noshow = settings.getString
("noshow", "NOT checked");
if (noshow != "checked" ) adb.show();
HAPPY CODING!
