自定义view adapter，一个RecycleView的强大adapter

前言

一般我们要在mainActivity中利用RecycleView展示一个列表数据的时候，adapter都是类似以下写法：

public class NameAdapter<T> extends RecyclerView.Adapter {protected Context mContext;protected View mLayoutView;protected List<T> mData;private ViewHolder mViewHolder;public NameAdapter(Context context, List<T> data) {this.mContext = context;this.mData = data;}@Overridepublic ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {mLayoutView = LayoutInflater.from(mContext).inflate(R.layout.item_layout, parent, false);mViewHolder = new ViewHolder(mLayoutView);return mViewHolder;}@Overridepublic int getItemCount() {return mData == null ? 0 : mData.size();}@Overridepublic void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {mViewHolder = ((ViewHolder) holder);initData(position);setListener(position);}private void initData(int position){mViewHolder.mTvName.setText(mData.get(position).toString());}private void setListener(int position){}class ViewHolder extends RecyclerView.ViewHolder {TextView mTvName;public ViewHolder(View view) {super(view);mTvName = (TextView) view.findViewById(R.id.tv_name);}}
}

然后在mainActivity中调用如下：

mNameList= Arrays.asList("小明","小红","小芳","小花","小海","小林","小叶","小虎","小柔");mRecyclerView.setHasFixedSize(true);mRecyclerView.setLayoutManager(new LinearLayoutManager(this));mNameAdapter = new NameAdapter<>(this, mNameList);mRecyclerView.setAdapter(mNameAdapter);

那么有什么方法能缩减NameAdapter中的代码，使我们在使用RecycleView进行列表数据展示的时候，把NameAdapter也的更简洁些呢，下面就给大家介绍一款adapter框架，相信在使用它后，将大大缩减NameAdapter的代码

1.配置

自定义view adapter？在projected的build.gradle中配置maven：

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

具体配置如下：

allprojects {repositories {google()jcenter()maven { url "https://jitpack.io" }}
}

在app module的build.gradle中添加依赖：

compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.34'

自此,配置结束.

2.写一个公共的adapter，名为ComAdapter，集成基本的初始化，加载动画等方法

public abstract class ComAdapter<T> extends BaseQuickAdapter<T, BaseViewHolder> {protected Context mContext;protected List<T>mData;protected int mItemViewId;//item布局idprotected View mHeaderView;protected View mFooterView;public ComAdapter(int itemViewId,List<T>data,Context context) {super(itemViewId, data);this.mItemViewId=itemViewId;this.mContext=context;this.mData=data;}@Overrideprotected void convert(BaseViewHolder viewHolder, T t) {initView(viewHolder,t);initData(viewHolder,t);setListener(viewHolder,t);}//以下代码见例子//......

3.自己写的NameAdapter继承于ComAdapter

public class NameAdapter<T>extends ComAdapter {private TextView mTvName;public NameAdapter(List<T> data, Context context){super(R.layout.item_layout,data,context);}@Overrideprotected void initView(BaseViewHolder viewHolder, Object o) {mTvName=viewHolder.getView(R.id.tv_name);}//以下代码省略//......

4.在mainActivity中的使用

声明

   @BindView(R.id.recycler_view)RecyclerView mRecyclerView;private List<String>mNameList;private NameAdapter mNameAdapter;

scrollview。初始化

        mNameList= Arrays.asList("小明","小红","小芳","小花","小海","小林","小叶","小虎","小柔");mNameAdapter=new NameAdapter(mNameList,mContext);//初始化NameAdaptermNameAdapter.setRecyclerManager(mRecyclerView);//设置RecyclerView特性mNameAdapter.addHeaderView(R.layout.item_header);//添加headermNameAdapter.addFooterView(R.layout.item_footer);//添加footermNameAdapter.openLeftAnimation();//设置加载动画

item点击事件

        //item點擊事件mNameAdapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {@Overridepublic void onItemClick(BaseQuickAdapter adapter, View view, int position) {Toast.makeText(MainActivity.this, "onItemLongClick" + position, Toast.LENGTH_SHORT).show();}});

item中子控件点击事件

 //子空控件点击事件mNameAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {@Overridepublic void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {Toast.makeText(MainActivity.this, "onItemLongClick" + mNameList.get(position), Toast.LENGTH_SHORT).show();}});
