在项目开发中或多或少都涉及到下拉刷新、上拉加载的效果，网上的第三方效果也有很多，当然也可以自己写，这里就大致说下SmartRefreshLayout。
SmartRefreshLayout支持下拉刷新、上拉加载、二级刷新、淘宝二楼、RefreshLayout、OverScroll，Android智能下拉刷新框架，支持越界回弹、越界拖动，具有极强的扩展性，集成了几十种炫酷的Header和 Footer，可以根据源码自定义实现Header和 Footer效果；接下来就看下如何将其集成到自己的项目中；这里采用的是源码集成的方式，非源码集成的方式很简单，可以参考SmartRefreshLayout github说明进行集成；
SmartRefreshLayout
根据上面的地址下载源码；打开源码会看到refresh-layout、refresh-header、refresh-footer、app-design等这几个model库；那就一个一个来弄；
refresh-layout
先将res目录下的文件全部拷贝到自己对应model下面，将refresh-layout model中build.gradle里面的依赖库拷贝到自己model中build.gradle文件中；
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
testCompile 'junit:junit:4.12'
//noinspection GradleDependency
compile 'com.android.support:support-annotations:25.1.0'
//noinspection GradleDependency,GradleCompatible
compile 'com.android.support:support-v4:22.1.0'
//noinspection GradleDependency,GradleCompatible
compile 'com.android.support:recyclerview-v7:21.0.0'
//noinspection GradleDependency,GradleCompatible
compile 'com.android.support:design:23.0.0'
}
将自己model下的AndroidManifest里面的包名改成com.scwang.smartrefresh.layout和它的一致，在新增model时弄为一致也可以，这样拷贝源码方便；将java目录下的源码拷贝到自己项目中rebuild下项目；refresh-layout弄没有问题了，就来弄refresh-header；
refresh-header
build.gradle：
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
testCompile 'junit:junit:4.12'
//noinspection GradleDependency
compile 'com.android.support:support-annotations:25.1.0'
//noinspection GradleDependency,GradleCompatible
compile 'com.android.support:support-v4:22.1.0'
compile project(':refresh-layout')
}
和上面一样，修改好包名(com.scwang.smartrefresh.header)并将源码拷贝进来；资源和源码拷贝好后，rebuild一下项目；refresh-footer、app-design这两个model没有什么用就没有弄了；弄好后，就可以用下看看有哪些效果了。
