Learning about Android

I am still learning about Android. Recently I have learned much better than a few days ago. Today I made another mistake. Of course, every time I make a mistake, I should give myself a warning, the mistake today was to use one view to get the ID of the control on the other view. After more than ten minutes, I checked it and suddenly understood it, I used to make this mistake all the time. Yesterday, when I was using a function, I was supposed to find it by lay. The result was also found by ID. The result was almost the same. I found it for one night, you must be careful when looking at the parameters! Wish you learn faster!
