ComposeAdapter

ComposeAdapter is an Android tool to compose your Adapter with various ViewHolder by simple Annotations.

Install

implementation 'com.github.jintin:composeadapter:0.1.0'
kapt 'com.github.jintin:composeadapter-compiler:0.1.0'

Usage

1. Add @BindHolder annotation to your Adapter with layout and model information.
   • You can also mark @BindLayout to your ViewHolder with layout id so adapter side can omit.
2. Change your super class to auto-generated class, name will as same as your current class name plus “Helper”.

   @BindHolder(ViewHolder1::class)
   @BindHolder(ViewHolder2::class, R.layout.item_holder2)
   class SampleAdapter(private val list: List<String>) : SampleAdapterHelper() {
    //...
   }
   @BindLayout(R.layout.item_holder1)
   class ViewHolder1(itemView: View) : RecyclerView.ViewHolder(itemView) {
    //...
   }
   class ViewHolder2(itemView: View) : RecyclerView.ViewHolder(itemView) {
    //...
   }
   

3. Build project, the related onCreateViewHolder method will be created in the auto-generated super class with static viewType int for further usage. ```java public abstract class SampleAdapterHelper extends RecyclerView.Adapter { protected static final int TYPE_VIEW_HOLDER1 = 0;

protected static final int TYPE_VIEW_HOLDER2 = 1;

@Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { switch (viewType) { case TYPE_VIEW_HOLDER1: { View view = LayoutInflater.from(parent.getContext()).inflate(2131296285, parent, false); return new ViewHolder1(view); } case TYPE_VIEW_HOLDER2: { View view = LayoutInflater.from(parent.getContext()).inflate(2131296286, parent, false); return new ViewHolder2(view); } default: throw new RuntimeException(“Not support type” + viewType); } } }

```
