问题 I have a grid view with various image views within it, and I want these images to disappear when touched. How can I do this? How can I implement a touch listener for these grid view images? 回答1: The ImageViews all are types of views and the layouts are ViewGroups. Any of these you can set the visibility to gone or removed. So really you just neeed to implement onTouchListener event handler and then set visibility on the ImageViews. So you might want to consider setting a whole layout to

问题 I just started working on an application for Android, to be specific - a service. I would like to create a service (background service, forcing itself to run, hidden, so it can't be shut down). and I don't have idea on how to construct it. How it is then launched and how to make it fit to those requirements.

问题 I'm implementing GCM in my app and I start the RegistrationIntentService in the main activity. What happens if I close the app before the intent finishes? The service takes a few seconds and I need the registration finishes despite the user has closed the app. This work this way or I have to do something more? Thanks! 回答1: Unless the system suddenly kills the application process, the intent will finish, because as a user you don't have direct control over when the app is actually closed
