Question

You can increase the font size of a message I display inside a AlertDialog?

Code:

builder.setMessage("Gasolina");
builder.setTitle("Sua melhor opção é:");
builder.setPositiveButton("OK",null);
builder.show();

Answer 1

Use this code below to change the text size:

AlertDialog dialog = new AlertDialog.Builder(this)
        .setTitle("Gasolina")
        .setMessage("Sua melhor opção é: ")
        .setPositiveButton("OK", null)
        .show();

        TextView textView = (TextView) dialog.findViewById(android.R.id.message);
        textView.setTextSize(40);
