Add it in your root build.gradle
at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://www.jitpack.io' }
}
}
Add dependencies in your module build.gradle
:
dependencies {
implementation 'com.github.DylanCaiCoding:LoadingStateView:3.0.1'
}
public class LoadingViewDelegate extends LoadingStateView.ViewDelegate<LoadingStateView.ViewHolder> {
@NonNull
@Override
public LoadingStateView.ViewHolder onCreateViewHolder(@NonNull LayoutInflater inflater, @NonNull ViewGroup parent) {
return new LoadingStateView.ViewHolder(inflater.inflate(R.layout.layout_loading_view, parent, false));
}
@Override
public void onBindViewHolder(@NonNull LoadingStateView.ViewHolder holder) {
}
}
LoadingStateView loadingStateView = new LoadingStateView(this);
loadingStateView.register(ViewType.LOADING, new LoadingViewDelegate());
loadingStateView.setViewDelegatePool(pool -> {
pool.register(ViewType.LOADING, new LoadingViewDelegate());
});
loadingStateView.showView(viewType);
loadingStateView.showLoadingView(); // view type is ViewType.LOADING
loadingStateView.showContentView(); // view type is ViewType.CONTENT
loadingStateView.showErrorView(); // view type is ViewType.ERROR
loadingStateView.showEmptyView(); // view type is ViewType.EMPTY
loadingStateView.setOnReloadListener(new LoadingStateView.OnReloadListener() {
@Override
public void onReload() {
// request data again
}
});
//In the adapter
holder.getOnReloadListener.onReload();
loadingStateView.updateView(ViewType.ERROR, (ErrorViewDelegate delegate) -> {
delegate.msg = "Fail to load, please wait";
});
If you want to add an ordinary title bar above the content.
Similar to the previous usage, create a class extends LoadingStateView.ViewDelegate<VH extends ViewHolder>
and set header.
loadingStateView.setDecorHeader(new TitleViewDelegate("title"), new SearchHeaderViewDelegate());
If you want to add an special title bar with linkage effect.
Create a class extends LoadingStateView.DecorViewDelegate
to create a decorated view and specify a loading container.
class ScrollingDecorViewDelegate : LoadingStateView.DecorViewDelegate() {
@NotNull
override fun onCreateDecorView(@NotNull inflater: LayoutInflater): View {
return inflater.inflate(R.layout.layout_scrolling, null)
}
@NotNull
fun getContentParent(@NotNull decorView: View): ViewGroup {
return decorView.findViewById(R.id.content_parent)
}
}
Then set it up.
loadingStateView.setDecorView(new ScrollingDecorViewDelegate());
The original name of this library is LoadingHelper
, and some class and method names should be changed later. Old users can check the migration guide and change it to the latest usage. If you feel troublesome and are not obsessive-compulsive, you can also not migrate.
