I am new to android development I am making a scorecalculator where I want to show a calculated output in a popup window. I have tried a lot of codes from yesterday and still the program doesn't work. Sometimes the activities even crash and don't open.

Here use AlertDialog.Builder

FloatingActionButton fab = findViewById(R.id.fab);
    fab.setOnClickListener(view -> {
        String myScore = "50 runs";
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setTitle("Cricket Score!");
        alertDialogBuilder.setMessage("Here is your final score: "+ myScore);
        alertDialogBuilder.setCancelable(false)
                .setPositiveButton("Yes", (dialog, id) -> {
                    Log.v("setPositiveButton","Yes Button");
                })
                .setNegativeButton("No", (dialog, id) -> {
                    // if this button is clicked, just close
                    // the dialog box and do nothing
                    dialog.cancel();
                });
        AlertDialog alertDialog = alertDialogBuilder.create();
        // show it
        alertDialog.show();
    });
