一个很赞的RecyclerView Adapter辅助类

是什么

BaseRecyclerViewAdapterHelper是一个强大并且灵活的RecyclerViewAdapter

能做什么

• 可以大量减少你Adapter写的代码（和正常的Adapter相比至少三分之二的）
• 可以添加点击事件
• 可以很轻松的添加RecyclerView加载动画
• 添加头部、添加尾部
• 支持下拉刷新、上拉加载更多
• 支持分组
• 支持自定义item类型
• 支持setEmptyView

• 支持子布局多个控件的点击事件

• 配置使用

  在 build.gradle 的 repositories 添加:

  12345

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

  然后增加dependencies

  123

  dependencies {    compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:v1.5.8'}

  创建Adapter

  123456789101112131415

  public class QuickAdapter extends BaseQuickAdapter<Status> {    public QuickAdapter(Context context) {        super(context, R.layout.tweet, DataServer.getSampleData());    }    @Override    protected void convert(BaseViewHolder helper, Status item) {        helper.setText(R.id.tweetName, item.getUserName())                .setText(R.id.tweetText, item.getText())                .setText(R.id.tweetDate, item.getCreatedAt())                .setImageUrl(R.id.tweetAvatar, item.getUserAvatar())                .setVisible(R.id.tweetRT, item.isRetweet())                .linkify(R.id.tweetText);    }}

  添加item点击事件

  
  
  

  23456

  mQuickAdapter.setOnRecyclerViewItemClickListener(new BaseQuickAdapter.OnRecyclerViewItemClickListener() {            @Override            public void onItemClick(View view, int position) {            }});

  23456

  mQuickAdapter.setOnRecyclerViewItemClickListener(new BaseQuickAdapter.OnRecyclerViewItemClickListener() {            @Override            public void onItemClick(View view, int position) {            }});

  
  

  添加动画

  12

  // 一行代码搞定（默认为渐显效果）quickAdapter.openLoadAnimation();

  另外也可以制定其他的动画效果

  123

  // 默认提供5种方法（渐显、缩放、从下到上，从左到右、从右到左）// ALPHAIN, SCALEIN, SLIDEIN_BOTTOM, SLIDEIN_LEFT, SLIDEIN_RIGHTquickAdapter.openLoadAnimation(BaseQuickAdapter.ALPHAIN);

  另外，如果内置的动画效果不满意，也可易自定义

  12345678910

  // 自定义动画如此轻松quickAdapter.openLoadAnimation(new BaseAnimation() {    @Override    public Animator[] getAnimators(View view) {       return new Animator[]{            ObjectAnimator.ofFloat(view, "scaleY", 1, 1.1f, 1),            ObjectAnimator.ofFloat(view, "scaleX", 1, 1.1f, 1)        };    }});

  添加多种类型item

  123456789101112131415161718192021

  public class MultipleItemQuickAdapter extends BaseMultiItemQuickAdapter<MultipleItem> {    public MultipleItemQuickAdapter(Context context, List data) {        super(context, data);        addItmeType(MultipleItem.TEXT, R.layout.text_view);        addItmeType(MultipleItem.IMG, R.layout.image_view);    }    @Override    protected void convert(BaseViewHolder helper, MultipleItem item) {        switch (helper.getItemViewType()) {            case MultipleItem.TEXT:                helper.setImageUrl(R.id.tv, item.getContent());                break;            case MultipleItem.IMG:                helper.setImageUrl(R.id.iv, item.getContent());                break;        }    }}

  添加头部及底部

  12

  mQuickAdapter.addHeaderView(getView());mQuickAdapter.addFooterView(getView());

  加载更多

  1234567891011121314151617

  mQuickAdapter.setOnLoadMoreListener(PAGE_SIZE, new BaseQuickAdapter.RequestLoadMoreListener() {            @Override            public void onLoadMoreRequested() {                if (mCurrentCounter >= TOTAL_COUNTER) {                    mRecyclerView.post(new Runnable() {                        @Override                        public void run() {                            mQuickAdapter.isNextLoad(false);                        }                    });                } else {                    // reqData                    mCurrentCounter = mQuickAdapter.getItemCount();                    mQuickAdapter.isNextLoad(true);                }            }        });

  使用分组

  1234567891011121314151617181920

  public class SectionAdapter extends BaseSectionQuickAdapter<MySection> {     public SectionAdapter(Context context, int layoutResId, int sectionHeadResId, List data) {        super(context, layoutResId, sectionHeadResId, data);    }    @Override    protected void convert(BaseViewHolder helper, MySection item) {        helper.setImageUrl(R.id.iv, (String) item.t);    }    @Override    protected void convertHead(BaseViewHolder helper,final MySection item) {        helper.setText(R.id.header, item.header);        if(!item.isMroe)helper.setVisible(R.id.more,false);        else        helper.setOnClickListener(R.id.more, new View.OnClickListener() {            @Override            public void onClick(View v) {                Toast.makeText(context,item.header+"more..",Toast.LENGTH_LONG).show();            }        });    }

  使用setEmptyView

  1

  mQuickAdapter.setEmptyView(getView());

  添加子布局多个控件的点击事件

  Adapter

  1234

  protected void convert(BaseViewHolder helper, Status item) {    helper.setOnClickListener(R.id.tweetAvatar, new OnItemChildClickListener())      .setOnClickListener(R.id.tweetName, new OnItemChildClickListener());}

  Activity

  12345678910111213141516

  mQuickAdapter.setOnRecyclerViewItemChildClickListener(new BaseQuickAdapter.OnRecyclerViewItemChildClickListener() {            @Override            public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {                String content = null;                Status status = (Status) adapter.getItem(position);                switch (view.getId()) {                    case R.id.tweetAvatar:                        content = "img:" + status.getUserAvatar();                        break;                    case R.id.tweetName:                        content = "name:" + status.getUserName();                        break;                }                Toast.makeText(AnimationUseActivity.this, content, Toast.LENGTH_LONG).show();            }        });
