Android Question Math inputs

Here is a suggestion - untried. I would start with a canvas and a maths symbol font. If you put a font file into the assets file folder then you will be able to use it in your app.

Position single maths symbol characters on the canvas - you will be able to adjust the size easily, but positioning them will probably need some care. I would overlay the canvas with a transparent panel and place text boxes on that panel at the required positions.

Another idea would be to display some maths symbols on a canvas, as suggested above, and then cut out some bitmaps containing the symbols to use again - this would make positioning much easier. Difficult to say more without knowing more about your design objective.

thank you Brian for your suggestion. I am trying to program a calculator app for android. inside of each rectangle user maybe wants to add another function and so on .something like i attached again here.i think it must be some sort of text for retrieving hole text entered by user for calculation purpose. I'll give a try for your suggestion and send feedback soon
