(i.e. running in the background and starting up automatically when the phone is restarted) 回答1: No, to both. The best you can do

My scenario is: thousands of users are making transactions and each user is accessing the same method again & again and just changing some values specific to that user or transaction. Now if I am making them as static methods then will it cause problems for users, as we know the adapter call is asynchronous....so if multiple users calling same method at the same time then will it cause

问题 I want to check the better and faster way for program of using adapter for a ListView. Is it out or in activity class? 回答1: This is more of a Java question than Android. Inner classes are more for making your code readable and do not affect performance as long as you use static inner classes . Static inner classes are pulled out by the compiler and compiled as separate classes (Class$InnerClass). So if using inner classes are helpful to you in terms of code organization, you can safely go

问题 In programming, which spelling—adapter or adaptor—is standard or de facto standard? Is there a difference between them? In boost I see "adaptor", whereas in literature I see "adapter". Which one is preferred in code? 回答1: They are both correct, though I think there's a slight preference for adapter to be used for people (such as someone who adapts a piece of music), while adaptor is used for a device or machine; thus, in computing, adaptor would generally be used. Wikipedia mentions this
