Android is really optimizing the APIs that are used on a local basis, which is more efficient than the Java version number. In addition, I found that the Android version number of the very many methods are added to the annotations. such as @findbugssup
finger item will return to the starting position, so that we know where to drag the item will be deleted, where the item is not deleted, the user experience better, there is an effect, Is that we slide deleted item, listview Other item will appear up or down scrolling effect, feel good, so in GitHub above search, found that a lot of open source Library has this effect, such as listviewanimations, Android-swipelistview and so on, I looked at the implementation of the principle of the use of Jake
1. ActionbarsherlockActionbarsherlock is a standalone Android design library that allows Android 2.x systems to use Actionbar as well. In addition, Actionbarsherlock allows developers to easily use and design Actionbar with just one API. Actionbarsherlock can also determine the choice and call the native Action bar or extend the Actionbar independently. If you use Actionbarsherlock above Android 3.x, it will also call system native Actionbar.2. Nine Old AndroidsSince Android 3.0 and above, the S

Just changed the entrance you use Com.nineoldandroids.XXX.The project consists of two projects, one is the library, the implementation of the animation effect, and the other is sample, is a demonstration of how to use the API. Developers can go directly to Google Play to download and install Nine old

Android uses NineOldAndroids to implement a left-slide display like listview to delete itembutton, androidlistview
This example uses NineOldAndroids to implement the itembutton deletion effect on the left slide of the imitation listview. We use the open-source library NineOldAndroids for animation of Jake Wharton. In API3.0 (Honeycomb), the SDK adds an android. the class in the animation package is related to the implementation of animation effects. The Honeycomb API can be used to achieve very

There are two ways of network request on Android, one is Java httpurlconnection, one is Apache HTTP clinet, but it is better to choose two ways? Excerpt from Android official blog:Which client is the best?Apache HTTP Client has fewer bugs on Eclair and Froyo. It's the best choice for these releases.For gingerbread and better, httpurlconnection are the best choice. Its simple API and small size makes it great fit for Android. Transparent compression and response caching reduce network use, improv
