, the first way of logic clear, very flexible, but to a certain extent increased memory and resource consumption. The second way is that the layout files are duplicated (although the same parts can be included, but logically there are duplicates), including essentially repetitive code that is handled logically. This approach is generally recommended for larger, different item layouts.Sometimes the combination of demand, can be based on the first way,
Why let the user use scroll when sliding (fling) is more efficient than moving (scroll)? On mobile devices with a small footprint and a lot of data, it is difficult to display the content scroll far behind, in which case fling is more appropriate.Note: Scroll indicates how much distance the finger slips, and how much distance the interface follows, while the fling is based on your sliding direction and weight, and automatically slides a distance.Filin
during implementation, so that the rendering function can be invoked whenever a frame is available. The graphics component provides an option in the UI component so that users can change the playback mode.The MEDIACODEC codec process is kept in sync with the video frame, and the renderer functionality in the graphics component is kept in sync with the graphics frame. Therefore, when you access the frame buffer, the functionality in the two components must be kept in sync.RELATED LINKS and resou

Original URL: http://blog.chinaunix.net/uid-26074270-id-2458828.htmlAndroid projects use Git and repo for version management. In most cases, git can meet the needs of the user. However, because Android projects are too large, it is not easy to manage these 100 + git libraries in a simple and efficient way. Repo is based on this requirement, a partial encapsulation of GIT commands to simplify some cross-netw

following describes how to use Eboot to erase NandFlash:
1. Use a serial port or USB to connect the Development Board and PC, and start minicom
2. Turn on the power, and enter the system five seconds later. The Blank Space key of the security PC keyboard causes the Development Board to stay in the Eboot status.
3. Enter "A" to erase it.
