52 | 53 | public static MApplication getInstance() { 54 | if (null == instance) { 55 | instance = new MApplication(); 56 | } 57 | return instance; 58 | } 59 | 60 | public MApplication() { 61 | 62 | } 63 | 64 | @Override 65 | public void onCreate() { 66 | super.onCreate(); 67 | instance = this; 68 | initLoadManager(); 69 | } 70 | 71 | private void initLoadManager() { 72 | PrePageManager.initManagerLayout(R.layout.layout_load_view,R.layout.layout_reload_view, 73 | R.layout.empty_view); 74 | } 75 | } 76 | ``` 77 |  - 在指定Activity或者Fragment或者View中注册Manager,前提是继承BaseActivity,你可以根据具体项目已有的BaseActivity或者BaseFragment模仿Demo里面的写法,加入到你的项目中 78 | 79 | ```java 80 | @Override 81 | protected void initPreManager() { 82 | super.initPreManager(); 83 | mPrePageManager = PrePageManager.generate(this, new DefaultLoadListener() { 84 | @Override 85 | public void onRetryClick(View retryView) { 86 | // Do Something 87 | loadData(); 88 | } 89 | 90 | }); 91 | } 92 | ``` 93 | 注: DefaultLoadListener已经经过另一层封装自定义了，原始的回调接口是OnLoadingAndRetryListener，在各个界面的显示前后都会有回调，如果想针对具体的某个Activity或者Fragment或者View进行布局，可以重载下面这些方法来替换Application中默认的布局 94 | 95 | ```java 96 | @Override 97 | public int generateLoadingLayoutId() { 98 | return super.generateLoadingLayoutId(); 99 | } 100 | 101 | @Override 102 | public int generateRetryLayoutId() { 103 | return super.generateRetryLayoutId(); 104 | } 105 | 106 | @Override 107 | public int generateEmptyLayoutId() { 108 | return super.generateEmptyLayoutId(); 109 | } 110 | ``` 111 | 112 | - 通过
113 | mPrePageManager.showLoading(delay,anim)
114 | mPrePageManager.showContent(delay,anim)
115 | mPrePageManager.showRetry(delay,anim)
116 | 去显示指定页面 117 | 118 | ##TODO 119 | -集成更多动画,增加页面切换过渡效果支持,优化Fragment下集成,注：上面的gif中activity之间的过渡动画是transition framework的动画并非框架动画（最近兴趣刚研究的），框架的动画添加是在Loading结束时显示内容页或者重载页的时候出现的动画。可以自定义成你想要的效果，demo中只是简陋的平移和渐变，后续会加入一些好看的默认动画！谢谢大家支持！ 120 | 121 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 25 5 | buildToolsVersion "25.0.1" 6 | defaultConfig { 7 | applicationId "com.zhangyf.loadmanager" 8 | minSdkVersion 9 9 | targetSdkVersion 25 10 | versionCode 1 11 | versionName "1.0" 12 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 13 | } 14 | buildTypes { 15 | release { 16 | minifyEnabled false 17 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 18 | } 19 | } 20 | } 21 | 22 | dependencies { 23 | compile fileTree(include: ['*.jar'], dir: 'libs') 24 | androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 25 | exclude group: 'com.android.support', module: 'support-annotations' 26 | }) 27 | compile 'com.android.support:appcompat-v7:25.0.+' 28 | compile 'com.jakewharton:butterknife:7.0.1' 29 | testCompile 'junit:junit:4.12' 30 | compile project(':LoadManagerLib') 31 | } 32 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # By default, the flags in this file are appended to flags specified 3 | # in D:\AndroidSdk/tools/proguard/proguard-android.txt 4 | # You can edit the include path and order by changing the proguardFiles 5 | # directive in build.gradle. 6 | # 7 | # For more details, see 8 | # http://developer.android.com/guide/developing/tools/proguard.html 9 | 10 | # Add any project specific keep options here: 11 | 12 | # If your project uses WebView with JS, uncomment the following 13 | # and specify the fully qualified class name to the JavaScript interface 14 | # class: 15 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 16 | # public *;
