public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        LoadSir.beginBuilder()
                .addCallback(new ErrorCallback())//添加各种状态页
                .addCallback(new EmptyCallback())
                .addCallback(new LoadingCallback())
                .addCallback(new TimeoutCallback())
                .addCallback(new CustomCallback())
                .setDefaultCallback(LoadingCallback.class)//设置默认状态页
                .commit();
    }
}

在Activity中使用

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_content);
    // Your can change the callback on sub thread directly.
    LoadService loadService = LoadSir.getDefault().register(this, new Callback.OnReloadListener() {
        @Override
        public void onReload(View v) {
            // 重新加载逻辑
            loadService.showCallback(LoadingCallback.class);
        }
    });
}}

在ImageView中使用

ImageView imageView = (ImageView) findViewById(R.id.iv_img);
LoadSir loadSir = new LoadSir.Builder()
        .addCallback(new TimeoutCallback())
        .setDefaultCallback(LoadingCallback.class)
        .build();
loadService = loadSir.register(imageView, new Callback.OnReloadListener() {
    @Override
    public void onReload(View v) {
        loadService.showCallback(LoadingCallback.class);
        // 重新加载逻辑
    }
});
Ps:
[1]要注册RelativeLayout或ConstraintLayout的子View，如果该子View被其它子View约束，建议在子View外层再包一层布局，参考
acitivy_view.xm和activity_constraintlayout.xml

Fragment中使用

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle
        savedInstanceState) {
    //第一步：获取布局View
    rootView = View.inflate(getActivity(), R.layout.fragment_a_content, null);
    //第二步：注册布局View
    LoadService loadService = LoadSir.getDefault().register(rootView, new Callback.OnReloadListener() {
        @Override
        public void onReload(View v) {
            // 重新加载逻辑
            loadService.showCallback(LoadingCallback.class);
        }
    });
    //第三步：返回LoadSir生成的LoadLayout
    return loadService.getLoadLayout();
}

回调

protected void loadNet() {
        // 进行网络访问...
        // 进行回调
        loadService.showSuccess();//成功回调
        loadService.showCallback(EmptyCallback.class);//其他回调
    }
