When you refer to the local code should be based on the need for appropriate changes, there are redundant code small series did not delete. OK, nonsense not to say, everything let the code speak! The key code looks like this: The main code inside Java public class Mai

control.Android also offers some of the more powerful data types, such as Sparsearray, Sparsebooleanarray, Sparseintarray, and Pair.The data structure of the sparse series is a special process for the case of the key int, using binary lookup and simple array storage, plus the overhead of not requiring a generic conversion, and better performance than the map. But I don't quite understand why the default capacity size is 10, is it statistical, or now memory optimization does not need to consider

In fact, this Android computer, all the backstage ideas and "C # calculator Code" is exactly the same. The Win form program is ported to Android, from C # to Java in fact, because the basic syntax is very similar, the only difficulty is the Android XML layout part, unlike C # forms can be directly dragged.Or a calculat
