TextView tv_message = new TextView(this);

                Typeface typeface = Typeface.createFromAsset(
                        getAssets(),
                        "fonts/OpenSans-Semibold.ttf"
                );


                // Set the text view layout parameters
                tv_message.setLayoutParams(
                        new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)
                );

                // Set message text color
                tv_message.setTextColor(Color.RED);

                // Set message gravity/text align
                tv_message.setGravity(Gravity.START);

                // Set message text size
                tv_message.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);

                // Set message custom font
                tv_message.setTypeface(typeface);

                // Set message background color
                tv_message.setBackgroundColor(Color.YELLOW);

                // Set message text padding
                tv_message.setPadding(15, 25, 15, 15);

                tv_message.setText("Are you sure?");
                tv_message.setTextColor(Color.BLACK);
