How to prevent a dialog from closing when a button is clicked

🙋‍♀️🙋‍♂️ Hey there! Having trouble with dialogs closing when a button is clicked? Don't worry, we've got you covered! In this blog post, we'll guide you through the process of preventing a dialog from closing when a button is clicked.

😕 Understanding the Problem

So, you have a dialog with an EditText for input, and you want to keep the dialog open when the "yes" button is clicked. However, if the input is incorrect, the dialog should stay open, and when the "no" button is clicked, the dialog should close automatically. Sounds like a common dilemma. Let's dive into the solutions!

🛠 Solution 1: Custom Dialog Class

One way to tackle this problem is by creating a custom dialog class. Here's how you can do it:

1. Create a new class extending DialogFragment:

public class MyCustomDialog extends DialogFragment {
    // your code here
}

1. Override the onCreateDialog method to build the dialog:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // build your dialog here
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // customize your dialog with title, message, and buttons
    builder.setTitle("My Dialog")
        .setMessage("Enter your input:")
        .setPositiveButton("Yes", null)
        .setNegativeButton("No", null);
    
    return builder.create();
}

1. Handle the button clicks in the onStart method. To prevent the dialog from closing when the "yes" button is clicked, override the onClick method for the positive button:

@Override
public void onStart() {
    super.onStart();
    
    AlertDialog dialog = (AlertDialog) getDialog();
    Button positiveButton = dialog.getButton(Dialog.BUTTON_POSITIVE);
    
    positiveButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // validate the input here
            if (isValidInput()) {
                // do something
            } else {
                // show an error message or perform other actions
            }
        }
    });
}

That's it! You have now created a custom dialog class that prevents the dialog from closing when the "yes" button is clicked.

🛠 Solution 2: Using setCancelable

Another simple way to achieve this is by using the setCancelable method. Here's how you can do it:

1. Create an instance of the AlertDialog.Builder class:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

1. Customize your dialog with a title, message, and buttons:

builder.setTitle("My Dialog")
    .setMessage("Enter your input:")
    .setPositiveButton("Yes", null)
    .setNegativeButton("No", null);

1. Call the setCancelable method on the AlertDialog.Builder instance and pass false as an argument:

builder.setCancelable(false);

1. Call the create method to create the dialog:

AlertDialog dialog = builder.create();

That's it! By setting setCancelable(false), you prevent the dialog from closing when any button is clicked.

📣 Wrapping it up

We've explored two solutions to prevent a dialog from closing when a button is clicked. Using a custom dialog class or setting setCancelable(false) are both effective ways to tackle this issue.
