RecyclerView万能适配器

一:BaseRecyclerViewAdapterHelper介绍

BaseRecyclerViewAdapterHelper是Github上为实现方便使用RecyclerView而开发的一个框架,使用较为简单方便,
能实现RecyclerView的下拉加载,Item点击事件,Item子控件的点击事件,Item加载动画等等
该适配器虽号称万能适配器,但并非万能,有很多功能本身是实现不了的,还会和其他开源的冲突,比如不能和XRecyclerView一起使用

配置

在 build.gradle 的 repositories 添加:

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

然后在Module的 build.gradle(Module:app) 的 dependencies 添加:

implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:v1.9.7'

二:使用方法

1,单类型BaseQuickAdapter使用

在这里插入图片描述
适配器

public class MyQuickAdapter extends BaseQuickAdapter<String> {

    private int layoutId;
    private List<String> list;

    public MyQuickAdapter(int layoutId,List<String> list){
        super(layoutId,list);
        this.layoutId = layoutId;
        this.list = list;
    }

    @Override
    protected void convert(BaseViewHolder baseViewHolder, String s) {
        //holder里有控件 showText
        baseViewHolder.setText(R.id.title_id,s);
    }
}

Activity

public class MainActivity extends AppCompatActivity {

    private RecyclerView recyclerViewId;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        recyclerViewId = (RecyclerView) findViewById(R.id.recyclerView_id);
        //线性
        LinearLayoutManager manager = new LinearLayoutManager(this);
        manager.setOrientation(RecyclerView.VERTICAL);
        recyclerViewId.setLayoutManager(manager);

        List<String> list = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            list.add("蜡笔小新"+i);
        }

        MyQuickAdapter myQuickAdapter = new MyQuickAdapter(R.layout.item_layout, list);
        recyclerViewId.setAdapter(myQuickAdapter);

    }
}

多类型BaseMultiItemQuickAdapter的用法:

在这里插入图片描述

public class RVAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    ArrayList<Bean> datas;

    public RVAdapter(ArrayList<Bean> datas) {
        this.datas = datas;
    }

    @Override
    public int getItemViewType(int position) {
        if (position % 2 == 0){//偶数返回0
            return 0;
        }else {
            return 1;
        }
    }

    @NonNull
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        if (viewType =&#
;
