AutoRecyclerAdapter

I'm writing a lot of repetition RecyclerView.Adapter,I feel most of the time write repeat if and else,like getItemViewType,onCreateViewHolder,onBindViewHolder and setSpanSizeLookup getSpanSize,exist a lot of if and else

Write repeat if and else become nightmare...

One day,I decided RecyclerView.Adapter use all if and else wipe out,let RecyclerView.Adapter Automated configuration.

中文文档

  • Use ViewHolder.class and reflect dynamic create ViewHolder
  • Use ViewHolder.class.hashCode() as RecyclerVew.Adapter ViewType
  • Use package class to ViewType,spanSize build connection,Is no longer create field or extend class
  • Use AutoHolder,dynamic set model
  • Create ViewHolder can set parameter,stand by key and value
  • Stand by GridLayoutManager setSpanSizeLookup,create complex arrangement

AutoRecyclerAdapter let Recycler. Adapter all methods Automated configuration. developer need outside config ViewHolder and Data. No need custom Recycler.Adapter. Stand by create complex arrangement and fast create like shopping app home page layout


2, Network reuqest seven different list

 List<ZhaoBean> zhaoList = ModelHelper.getZhaoList(1);
 List<QianBean> qianList = ModelHelper.getQianList(10);
 List<SunBean> sunList = ModelHelper.getSunList(1);
 List<LiBean> liList = ModelHelper.getLiList(4);
 List<ZhouBean> zhouList = ModelHelper.getZhouList(10);
 List<WuBean> wuList = ModelHelper.getWuList(1);
 List<ZhengBean> zhengList = ModelHelper.getZhengList(30);

3, Set up seven different List to ViewHolder,use Holder.class.hashCode() as ViewType

 autoRecyclerAdapter.setDataListSpan(AutoBannerHolder.class, zhaoList, SPAN_SIZE)
 .setDataListSpan(AutoTypeAHolder.class, qianList, SPAN_SIZE / 5)
 .setDataListSpan(AutoTypeBHolder.class, sunList, SPAN_SIZE)
 .setDataListSpan(AutoTypeCHolder.class, liList, SPAN_SIZE / 2)
 .setDataListSpan(AutoTypeDHolder.class, zhouList, SPAN_SIZE / 5)
 .setDataListSpan(AutoTypeEHolder.class, wuList, SPAN_SIZE)
 .setDataListSpan(AutoTypeFHolder.class, zhengList, SPAN_SIZE / 2)
 .notifyDataSetChanged();

Other

1, if only use one List and one ViewHolder

 autoRecyclerAdapter = new AutoRecyclerAdapter();
 .setHolder(AutoTypeAHolder.class, R.layout.item_type_a);

 autoRecyclerAdapter.setDataList(AutoTypeAHolder.class, qianList)
      .notifyDataSetChanged();

2, if use two List and two ViewHolder

 autoRecyclerAdapter = new AutoRecyclerAdapter();
 .setHolder(AutoTypeAHolder.class, R.layout.item_type_a)
 .setHolder(AutoTypeBHolder.class, R.layout.item_type_b);

 autoRecyclerAdapter.setDataList(AutoTypeAHolder.class, qianList)
      .setDataList(AutoTypeBHolder.class, sunList)
      .notifyDataSetChanged();

3, if use GridLayoutManager setSpanSizeLookup

 autoRecyclerAdapter = new AutoRecyclerAdapter();
 manager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
 @Override public int getSpanSize(int position) {
 return autoRecyclerAdapter.getSpanSize(position);
 }
 });

 autoRecyclerAdapter = new AutoRecyclerAdapter();
 .setHolder(AutoTypeAHolder.class, R.layout.item_type_a)
 .setHolder(AutoTypeBHolder.class, R.layout.item_type_b);

 int spanSizeA = 2;
 int spanSizeB = spanSizeA / 2;

 autoRecyclerAdapter.setDataList(AutoTypeAHolder.class, qianList, spanSizeA)
      .setDataList(AutoTypeBHolder.class, sunList, spanSizeB)
      .notifyDataSetChanged();

Expand

1,Stand by to ViewHolder transfer parameter: key and value like map

 public <H extends AutoHolder> AutoRecyclerAdapter setHolderToData(Class<H> holderClass,
     int layoutRes, Map<String, Object> dataMap) {
     return setHolderToData(holderClass.hashCode(), holderClass, layoutRes, dataMap);
 }

 public <H extends AutoHolder> AutoRecyclerAdapter setHolderToListener(Class<H> holderClass,
 int layoutRes, String key, Object value, OnAutoHolderListener listener) {
  Map<String, Object> dataMap = new HashMap<>();
  dataMap.put(key, value);
  dataMap.put(AutoHolder.LISTENER, listener);
  return setHolderToData(holderClass.hashCode(), holderClass, layoutRes, dataMap);
 }

2,Stand by use GridLayoutManager setSpanSizeLookup,create complex arrangement

 public <H extends AutoHolder, M> AutoRecyclerAdapter setDataObjectSpan(Class<H> holderClass,
     M bean, int spanSize) {
     return setDataObject(holderClass.hashCode(), bean, spanSize);
 }

 public <H extends AutoHolder, M> AutoRecyclerAdapter setDataListSpan(Class<H> holderClass,
 List<M> list, int spanSize) {
  return setDataList(holderClass.hashCode(), list, spanSize);
 }

Class

One core class,four auxiliary class

name description
AutoRecyclerAdapter Automated configuration Recycler.Adapter core class
AutoHolder Automated configuration need ViewHolder
AutoPackage AutoRecyclerAdapter need model
AutoHolderPackage Automated create VewHolder need model
OnAutoHolderListener AutoHolder outside build connection example

Gradle

Add it in your root build.gradle at the end of repositories:

 allprojects {
  repositories {
   ...
   maven { url 'https://jitpack.io' }
  }
 }

Add the dependency:

 dependencies {
         compile 'com.github.teambition:AutoRecyclerAdapter:v1.5'
 }

Proguard

-keep public class * extends zhan.auto_adapter.AutoHolder {
    public <init>(android.view.View, java.util.Map);
}
