SwiftAdapter
SwiftAdapter is an easy to use expandable list recyclerview adapter
- extend one class to get all the features
- easy and quick to setup
- easy to customize
Version
Note: this version is stable but I have not tested on anything outside my own devices and my specific data sets. For best results try to not steer too far away from the sample project.
Preview
A sample app has been included with the project, just compile and run, or install this sample apk. You can also watch a preview video. I'm working on releasing a version to the play store soon.
Import Using Gradle
compile 'com.vkondrav.swiftadapter:swift-adapter:0.2.1'Quickstart
Extend the SwiftAdapter
private static class Adapter extends SwiftAdapter<Adapter.ViewHolder> {
Declare you main ViewHolder
public class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(View itemView) {
super(itemView);
}
}
Override count method to declare how many items of that type you will have
@Override public int getNumberOfLvl0Items() {
return 10;
}
Override onCreate method to create a specific type of item
@Override public ViewHolder onCreateLvl0ItemViewHolder(ViewGroup parent) {
return new ViewHolder(layoutInflater.inflate(R.layout.lvl0_item_layout, parent, false));
}
Override to bind data to the viewholder
@Override public void onBindLvl0Item(ViewHolder holder, ItemIndex index) {
}
Advanced
There are 4 Levels where the view holders can exist. Each section hosts the items and sections below it.
- Level 0 Items
- Level 1 Sections
- Level 1 Items
- Level 2 Sections
- Level 2 Items
- Level 3 Sections
- Level 3 Items
Each layer has a set of methods to construct it. By overriding these methods you can create each layer of the list
int getNumberOf_() ViewHolder CreateViewHolder_() void BindViewHolder_(ViewHolder holder, ItemIndex)Open and Close each section by calling these methods and passing ItemIndex from that section.
void openCloseLvl1Section(ItemIndex itemIndex);
void openCloseLvl2Section(ItemIndex itemIndex);
void openCloseLvl3Section(ItemIndex itemIndex);
ItemIndex can always be obtained from the specific OnBind Method or by calling getCurrentItemIndex and passing the ViewHolder for that section
public ItemIndex getCurrentItemIndex(T holder)
