Elementary school arithmetic mental arithmetic practice app---No.5

Today the main set of answer page, mainly is the question page and answer page between the issue of the problem and the answer page display problem! This is used to wrap the title of the array into a number of string types (including the equals sign and the user's answer) to wrap the correct answer in a separate array, and to wrap the relevant hints into an array, inside the Calculatoractivity.class!

The code is as follows:

The results are as follows

Because each problem consists of a different length of string, the position cannot be fixed! Only add empty style to try! It's supposed to be.

Later it was changed to the above code as described above, no matter how the location is not fixed (for such an array to pass the argument!) ）
