dependencies {
    implementation 'com.classic.adapter:commonadapter:2.0'
    implementation 'com.android.support:recyclerview-v7:27.0.2'
}

开始使用

ListView/GridView 使用示例

List<News> newsList = ...;
//单布局文件
listView = (ListView) findViewById(R.id.listview);
listView.setAdapter(new CommonAdapter<News>(context,
    //item 布局文件
    R.layout.item_none_picture, newsList ) {
    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        //BaseAdapterHelper 详细用法，见下方

        helper.setText(R.id.xxx, item.getTitle())
               //1.如果已配置全局图片加载，这里可以不设置。全局图片加载配置见下方
               //2.有些项目可能使用多个图片加载库，这里可以针对当前 adapter 设置图片加载的实现方式，详见 demo
              .setImageLoad(new GlideImageLoad())
              .setImageUrl(R.id.xxx,item.getCoverUrl());
    }
});

//多布局文件
private final class MultipleLayoutAdapter extends CommonAdapter<News>{

    public MultipleLayoutAdapter(Context context, int layoutResId, List<News> data) {
        super(context, layoutResId, data);
    }
    //多种布局重写此方法即可
    @Override public int getLayoutResId(News item, int position) {
        int layoutResId = -1;
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                layoutResId = R.layout.item_none_picture;
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                layoutResId = R.layout.item_single_picture;
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                layoutResId = R.layout.item_multiple_picture;
                break;

            更多的布局样式 ...
        }
        return layoutResId;
    }

    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;

            更多的布局样式 ...
        }
    }
}

RecyclerView 使用示例

使用 DiffUtil 高效更新 RecyclerView 示例代码，点这里

List<News> newsList = ...;
//单布局文件
recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
recyclerView.setItemAnimator(new DefaultItemAnimator());
newsAdapter = new NewsAdapter(this, R.layout.item_none_picture, newsList);
recyclerView.setAdapter(newsAdapter);

private class NewsAdapter extends CommonRecyclerAdapter<News>{

    public NewsAdapter(Context context, int layoutResId, List<News> data) {
        super(context, layoutResId, data);
    }

    @Override public void onCreate(RecyclerView.ViewHolder viewHolder, BaseAdapterHelper helper) {
        // ViewHolder 创建时回调
    }

    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        helper.setText(R.id.xxx, item.getTitle())
              .setImageUrl(R.id.xxx,item.getCoverUrl());
    }
}

//多布局文件
private final class MultipleLayoutAdapter extends CommonRecyclerAdapter<News>{

    public MultipleLayoutAdapter(Context context, int layoutResId, List<News> data) {
        super(context, layoutResId, data);
    }

    @Override public void onCreate(RecyclerView.ViewHolder viewHolder, BaseAdapterHelper helper) {
        // ViewHolder 创建时回调
    }

    //多种布局重写此方法即可
    @Override public int getLayoutResId(News item, int position) {
        int layoutResId = -1;
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                layoutResId = R.layout.item_none_picture;
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                layoutResId = R.layout.item_single_picture;
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                layoutResId = R.layout.item_multiple_picture;
                break;

            更多的布局样式 ...
        }
        return layoutResId;
    }

    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;

            更多的布局样式 ...
        }
    }
}

RecyclerView 点击事件

commonRecyclerAdapter.setOnItemClickListener(this) // 设置 item 点击事件
                     .setOnItemLongClickListener(this) // 设置 item 长按事件
                     // 设置 Child view 的点击、长按、Touch 事件(方式一)
                     // OnChildViewClickListener 、 OnChildViewLongClickListener 、 OnChildViewTouchListener
                     .addChildViewListener(R.id.viewId, listener);

BaseAdapterHelper 使用示例

helper.setText(R.id.viewId, text)
      .setTag(R.id.viewId, objectTag)
      .setAlpha(R.id.viewId, 0.6f)
      .setBackgroundColor(R.id.viewId, R.color.colorResId)
      .setBackgroundRes(R.id.viewId, R.drawable.drawableResId)
      .setChecked(R.id.viewId, true)
      .setImageBitmap(R.id.viewId, bitmap)
      .setImageDrawable(R.id.viewId, drawable)
      .setImageResource(R.id.viewId, R.drawable.drawableResId)
      .setImageUrl(R.id.viewId, url)
      .setProgress(R.id.viewId, progress)
      .setProgress(R.id.viewId, progress, max)
      .setRating(R.id.viewId, rating)
      .setRating(R.id.viewId, rating, max)
      .setTextColor(R.id.viewId, R.color.colorResId)
      .setTextColorRes(R.id.viewId, R.color.colorResId)
      .setTextColorRes(R.id.viewId, R.color.colorResId, theme)
      //TextView 添加超链接，更多属性参考：android.text.util.Linkify#addLinks(TextView text, int mask)
      .addLinks(R.id.viewId, Linkify.ALL)
      //效果同上
      .addAllLinks(R.id.viewId)
      //单个 TextView 设置 Typeface
      .setTypeface(R.id.viewId, typeface)
      //多个 TextView 设置 Typeface
      .setTypeface(typeface, R.id.xxx1, R.id.xxx2, R.id.xxx3, ...)
      .setVisible(R.id.viewId, View.VISIBLE)
      //ProgressBar 设置 Max
      .setMax(R.id.viewId, max)
      //ListView、RecyclerView 设置 adapter
      .setAdapter(R.id.viewId, adapter)
      // 设置 Child view 的点击、长按、Touch 事件(方式二)
      .setOnTouchListener(R.id.viewId, onTouchListener)
      .setOnClickListener(R.id.viewId, onClickListener)
      .setOnLongClickListener(R.id.viewId, onLongClickListener)
      .setOnItemClickListener(R.id.viewId, onItemClickListener)
      .setOnItemLongClickListener(R.id.viewId, onItemLongClickListener)
      .setOnItemSelectedClickListener(R.id.viewId, onItemSelectedListener);

//获取 item 的 convertView
View convertView = helper.getView();

//如果上面的属性不够用,可以通过 getView(viewId)拿到 View,然后进行属性设置
View childView = helper.getView(R.id.viewId);

配置全局图片加载的实现类

public class YourApplication extends Application {

    @Override public void onCreate() {
        super.onCreate();

        ...

        ImageLoad imageLoadImpl = new GlideImageLoad();
        Adapter.config(new Adapter.Builder().setImageLoad(imageLoadImpl));
    }
}

自定义图片加载

public class YourXXX implements ImageLoad {

    @Override public void load(Context context, ImageView imageView, String imageUrl) {

        //使用 Glide 加载图片
        Glide.with(context).load(imageUrl).into(imageView);

        or

        //使用 Picasso 加载图片
        Picasso.with(context).load(url).into(imageView);

        or

        Fresco
        Android-Universal-Image-Loader
        自定义
        ...
    }
}

常用的数据操作

//CommonAdapter、CommonRecyclerAdapter 都实现了 IData 接口，里面包含了一些常用的数据操作

void add(T elem);

void addAll(List<T> elem);

void set(T oldElem, T newElem);

void set(int index, T elem);

void remove(T elem);

void remove(int index);

void replaceAll(List<T> elem);

boolean contains(T elem);

void clear();
