This is my online to find a similar one, I changed, is that he will get the current state of the seat to a list, a list containing the number of the Point type, I give him to the first data is I * m + j, said the first row of the first j column, then the second data 1 is selected, this time with the picture of the green, 2 said confirmation has been selected, in red, images,
This seems to be updated in real time, then I create a rectangular section, instead of the confirm button to do the work, had been added a button component and then calls the function outside unsure (), the results not only change, should now feel I was unsure () and response way,,, here is a custom View class and I error related content, parameter definitions and some basic functions are actually I deleted
