What is the best way to display a set of points on Android?

Question

Java

I am writing a program (for Android) to configure the sensor via bluetooth. The sensor protocol itself is sharpened for a segmented iron screen (that is, the sensor sends me the letter "A", for example, with a 5x7 matrix, and I must display it point by point as on a segment indicator).
The question is how best to do this on Android and to fit all the most common screen resolutions, and how to make the characters smooth (as if the letter does not consist of dots, but straight smoothed A)?

Answer 1

Maybe I didn't understand the question very well.
Create a dictionary "matrix = letter" in the program,
each matrix corresponds to a specific letter.
Matrices come to you, you
form an array of letters through the dictionary,
and the TextView displays.
You can choose the font from Google to your taste.
