How to create a Custom Dialog box in android?

Creating a custom dialog box in Android involves the following steps:

Create a new layout file for the dialog box. This can be done by right-clicking on the "res/layout" folder in your project and selecting "New > Layout resource file". Give the file a name and add the necessary UI elements.

Create a new Java class for the custom dialog box. This can be done by right-clicking on the package where you want to create the class and selecting "New > Java class". Give the class a name and make it extend the Dialog class.

In the class constructor, call the superclass constructor and set the content view to the layout file you created in step 1. You can do this using the setContentView() method.

Add any necessary methods to the class to customize the dialog box behavior. For example, you can add a method to set the title or message of the dialog box, or add buttons with click listeners.

In your app code, create an instance of the custom dialog box class and call the show() method to display it on the screen. You can also customize the appearance and behavior of the dialog box by calling any additional methods you defined in step 4.

Here is an example code for creating a custom dialog box:

public class CustomDialog extends Dialog {

    private TextView titleTextView;

    private TextView messageTextView;

    private Button okButton;

    private Button cancelButton;

    public CustomDialog(Context context) {

        super(context);

        setContentView(R.layout.custom_dialog_layout);

        titleTextView = findViewById(R.id.titleTextView);

        messageTextView = findViewById(R.id.messageTextView);

        okButton = findViewById(R.id.okButton);

        cancelButton = findViewById(R.id.cancelButton);

        okButton.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                // Handle OK button click

                dismiss();

            }

        });

        cancelButton.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                // Handle cancel button click

                dismiss();

            }

        });

    }

    public void setTitle(String title) {

        titleTextView.setText(title);

    }

    public void setMessage(String message) {

        messageTextView.setText(message);

    }

}

To use this custom dialog box in your app code, you can create a new instance of the class and call the setTitle() and setMessage() methods to customize the dialog box. Then, call the show() method to display it on the screen.

CustomDialog dialog = new CustomDialog(this);

dialog.setTitle("Title");

dialog.setMessage("Message");

dialog.show();
