Progress Fragment 不确定进度指示器 加载数据

Android-ProgressFragment ======================== [](https://android-arsenal.com/details/1/366) Implementation of the fragment with the ability to display indeterminate progress indicator when you are waiting for the initial data. Based on [ListFragment](http://developer.android.com/reference/android/app/ListFragment.html). Sample ------ A sample application is available on Google Play: <a href="http://play.google.com/store/apps/details?id=com.devspark.progressfragment.sample"> <img alt="Get it on Google Play" src="http://www.android.com/images/brand/get_it_on_play_logo_small.png" /> </a> ![screenshot][1] Compatibility ------------- This library is compatible from API 4 (Android 1.6). Usage ----- To display the progress fragment you need the following code: * Create your implementation of progress fragment ``` java public class MyProgressFragment extends ProgressFragment { // your code of fragment } ``` or if you use [ActionBarSherlock](https://github.com/JakeWharton/ActionBarSherlock) ``` java public class MyProgressFragment extends SherlockProgressFragment { // your code of fragment } ``` * Setup content view and empty text (optional) in `onActivityCreate()` method. ``` java @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); // Setup content view setContentView(R.layout.content); // Setup text for empty content setEmptyText(R.string.empty); // ... } ``` * Display of indeterminate progress indicator ``` java setContentShown(false); ``` * When the data is loaded to set whether the content is empty and show content ``` java setContentEmpty(/* true if content is empty else false */); setContentShown(true); ``` Gradle ------ Android-ProgressFragment library is now pushed to Maven Central as a AAR, so you just need to add the following dependency to your build.gradle. ProgressFragment (support-v4): ``` xml dependencies { compile 'com.github.johnkil.android-progressfragment:progressfragment:1.4.+' } ``` ProgressFragment (native): ``` xml dependencies { compile 'com.github.johnkil.android-progressfragment:progressfragment-native:1.4.+' } ``` SherlockProgressFragment: ``` xml dependencies { compile 'com.android.support:support-v4:19.0.0' compile('com.github.johnkil.android-progressfragment:sherlockprogressfragment:1.4.+') { exclude module: 'support-v4' } } ``` Example Gradle project using Android-ProgressFragment: * [Android-ProgressFragment-Gradle-Sample](https://github.com/johnkil/Android-ProgressFragment-Gradle-Sample) Developed By ------------ * Evgeny Shishkin - <johnkil78@gmail.com> License ------- Copyright 2013 Evgeny Shishkin Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
