LoadSir is a lightweight, good expandability Android library used for displaying different pages like loading, error, empty, timeout or even your custom page when you load a page(such as do net job). LoadSir is very different from other similar libraries. I mean... better.

- ⭐ support for Activity, Fragment, Fragment(v4), View
- ⭐ support for muitl-Fragment, Fragment+ViewPager
- ⭐ convert http result structure into a Callback
- ⭐ only load one layout once
- ⭐ don't need to set enum or constant for status code
- ⭐ set the your own onclick logic in custom Callback
- ⭐ no preloaded load page
- set the retry onclick listener
- allow to cusomize your own load page
- thread-safety
- set the default load page
- add muitl load pages
LoadSir only needs 3 steps to finish his task.
compile 'com.kingja.loadsir:loadsir:1.2.0'The are two ways to set config. Add your custom pages and set the default page.
Set config with singleton pattern, you can do it in your Application, so that you could get this unique LoadSir everywhere.
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
LoadSir.beginBuilder()
.addCallback(new ErrorCallback())
.addCallback(new EmptyCallback())
.addCallback(new LoadingCallback())
.addCallback(new TimeoutCallback())
.addCallback(new CustomCallback())
.setDefaultCallback(LoadingCallback.class)
.commit();
}
}If your want to create another specific LoadSir, you can set config like this.
LoadSir loadSir = new LoadSir.Builder()
.addCallback(new LoadingCallback())
.addCallback(new EmptyCallback())
.addCallback(new ErrorCallback())
.build();
loadService = loadSir.register(this, new Callback.OnReloadListener() {
@Override
public void onReload(View v) {
// retry logic
}
});Tell LoadSir which one you want replace it's layout with LoadLayout.
@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) {
// retry logic
}
});
}}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);
// retry logic
}
});Use it in Fragment is a bit different from the other two, follow the template code.
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle
savedInstanceState) {
//step 1：obtain get root view
rootView = View.inflate(getActivity(), R.layout.fragment_a_content, null);
//step 2：obtain the LoadService
LoadService loadService = LoadSir.getDefault().register(rootView, new Callback.OnReloadListener() {
@Override
public void onReload(View v) {
// retry logic
}
});
//step 3：return the LoadLayout from LoadService
return loadService.getLoadLayout();
}protected void loadNet() {
// do net job...
// callback
loadService.showSuccess();//successful case
loadService.showCallback(EmptyCallback.class);//other case
}If you want LoadSir to do callback automatically, you can pass a Convertor when you register.
LoadService loadService = LoadSir.getDefault().register(this, new Callback.OnReloadListener() {
@Override
public void onReload(View v) {
// retry logic
}}, new Convertor<HttpResult>() {
@Override
public Class<? extends Callback> map(HttpResult httpResult) {
Class<? extends Callback> resultCode = SuccessCallback.class;
switch (httpResult.getResultCode()) {
case SUCCESS_CODE:
if (httpResult.getData().size() == 0) {
resultCode = EmptyCallback.class;
}else{
resultCode = SuccessCallback.class;
}
break;
case ERROR_CODE:
resultCode = ErrorCallback.class;
break;
}
return resultCode;
}
});Pass a HttpResult, now you start up a robot LoadSir.
loadService.showWithConvertor(httpResult);You can customize your own load page, like loading, empty, error, timeout, etc. Provide the layout and fill the retry logic(if necessarily).
public class CustomCallback extends Callback {
@Override
protected int onCreateView() {
return R.layout.layout_custom;
}
@Override
protected boolean onRetry(final Context context, View view) {
Toast.makeText(context.getApplicationContext(), "Hello mother fuck! :p", Toast.LENGTH_SHORT).show();
(view.findViewById(R.id.iv_gift)).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context.getApplicationContext(), "It's your gift! :p", Toast.LENGTH_SHORT).show();
}
});
return true;
}
