SuperAdapter

Adapter(ListAdapter, RecyclerView.Adapter) wrapper for android.

Less code for redundant adapter. You won't need to write ViewHolder, createView, setTag, getTag, and confuse how to setOnItemClickListener to RecyclerView, etc. The only thing you really need to do is that implement a method onBind().

Android Studio:

In build.gradle:

compile 'org.byteam.superadapter:superadapter:latestVersion@aar'

Eclipse:

Add latest Jar to libs dir manually.

Features

• Less code!
• Header and footer.
• OnItemClickListener and OnItemLongClickListener.
• Hide view holder.
• Supports both BaseAdapter and RecyclerView.Adapter.
• Wraps CRUD.

How to use

If a simple adapter, it can be simplified like this:

public class SingleAdapter extends SuperAdapter<String> {
	public SingleAdapter(Context context, List<String> list, int layoutResId) {
		super(context, list, layoutResId);
	}

	@Override
	public void onBind(SuperViewHolder holder, int viewType, int position, String item) {
		holder.setText(R.id.tv_name, item);
	}
}

Then:

mSingleAdapter = new RecyclerSingleAdapter(getContext(), names, R.layout.your_item);  
recyclerView.setAdapter(mSingleAdapter);

If a complex adapter, it can be simplified like this:

public class MultipleAdapter extends SuperAdapter<MockModel> {
	public MultipleAdapter(Context context, List<MockModel> list, IMulItemViewType<MockModel> multiItemViewType) {
		super(context, list, multiItemViewType);
	}

	@Override
	public void onBind(SuperViewHolder holder, int viewType, int position, MockModel item) {
		switch (viewType) {
			case 0:
				holder.setText(R.id.tv_name, item.getName());
				break;
			case 1:
				holder.setText(R.id.tv_name, item.getName());
				holder.setImageResource(R.id.iv_portrait, R.mipmap.ic_launcher);
				holder.setText(R.id.tv_age, String.valueOf(item.getAge()));
				break;
		}
	}
}

Then:

multiAdapter = new MultipleAdapter(getContext(), models, new IMulItemViewType<MockModel>() {
	@Override
	public int getItemViewType(int position, MockModel mockModel) {
		if (position % 2 == 0) {
			return 0;
		}
		return 1;
	}

	@Override
	public int getLayoutId(int viewType) {
		if (viewType == 0) {
			return R.layout.item_type1;
		}
		return R.layout.item_type2;
	}

	@Override
	public int getViewTypeCount() {
		return 2;
	}
});
recyclerView.setAdapter(mMultiAdapter);

If you don't want to offer IMulItemViewType when creating adapter, you can override offerMultiItemViewType() in adapter:

@Override
protected IMulItemViewType<MockModel> offerMultiItemViewType() {
	return new IMulItemViewType<MockModel>() {
		@Override
		public int getViewTypeCount() {
				return 2;
		}

		@Override
		public int getItemViewType(int position, MockModel mockModel) {
			if (position % 2 == 0) {
				return 0;
			}
			return 1;
		}

		@Override
		public int getLayoutId(int viewType) {
			if (viewType == 0) {
				return R.layout.item_type1;
			}
			return R.layout.item_type2;
		}
	};
}

Then:
multiAdapter = new MultipleAdapter(getContext(), models, null);
If using RecyclerView, you can also use class SimpleMulItemViewType:

mAdapter = new MultipleAdapter(getContext(), models, new SimpleMulItemViewType<MockModel>() {
	@Override
	public int getItemViewType(int position, MockModel mockModel) {
		if (position % 2 == 0) {
			return 0;
		}
		return 1;
	}

	@Override
	public int getLayoutId(int viewType) {
		if (viewType == 0) {
			return R.layout.item_type1;
		}
		return R.layout.item_type2;
	}
});
recyclerView.setAdapter(mAdapter);
