BaseAdapter

Setup and usage

installation

with gradle

Step 1. Add the JitPack repository to your build file

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

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

Step 2. Add the dependency

Assuming you have installed jitpack provider:

dependencies {
        compile 'com.github.donniesky:BaseAdapter:v0.1.1'
}

or just import library module to your project.

Features

BaseAdapter

BaseAdapter allows you to shorten the code of most usual BaseAdapter, taking care of implementing everything for you based on your data list. You only need to focus on the mapping between your view and your model. this library is to build your adapters by composing reusable components,

• Favor composition over inheritance .

Usage

For single item adapter:

public class TestAdapter extends BaseAdapter<String, BaseViewHolder> {

    public TestAdapter() {
        super(R.layout.list_item);
    }

    @Override
    protected void convert(BaseViewHolder holder, String s, int position) {
        holder.setText(R.id.txt, s);
    }
}

For MultiItem adapter:

public class Test2Adapter extends MultiItemAdapter<String, BaseViewHolder> {
    public Test2Adapter() {
        super(null);

        addItemViewDelegate(new ItemDefaultDelegate());
        addItemViewDelegate(new Item1Delegate());
        addItemViewDelegate(new Item2Delegate());
    }
}

define an ItemViewDelegate for each view type. This delegate is responsible for creating ViewHolder and binding ViewHolder for a certain viewtype. An ItemViewDelegate get added to an ItemViewDelegateManager. This manager is the man in the middle between RecyclerView.Adapter and each ItemViewDelegate.

For example:

public class Item1Delegate implements ItemViewDelegate<String> {
    @Override
    public int getItemViewLayoutId() {
        return R.layout.view_item_1;
    }

    @Override
    public boolean isForViewType(String item, int position) {
        return item.equals("2");
    }

    @Override
    public void convert(BaseViewHolder holder, String s, int position) {
        holder.setText(R.id.txt1, s);
    }
}

Walle

Proxy Pattern.

• No need change anything with your target adapter;
• Not destory target adapter position;
• Support dynamic add & remove;
• No dependencies code build order

Usage

Walle walle = Walle.newBuilder()
                .enableHeader(true)
                .headerRes(R.layout.view_header)
                .enableFooter(true)
                .footerRes(R.layout.view_footer)
                .enableLoadMore(true)
                .loadmoreRes(R.layout.view_load_more)
                .addLoadMoreListener(this)
                .wrapperAdapter(adapter).build();
		
rv.setAdapter(walle.getWrapperAdapter());

adapter.setData(getdatas());
