//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()) //可实现ImageLoad接口，进行图片自定义加载方式，demo里面使用的Glide .setImageLoad(new GlideImageLoad()) .setImageUrl(R.id.xxx,item.getCoverUrl());

break; 更多的布局样式 ... } } }</code></pre> <p>RecyclerView 使用示例</p> <pre> <code class="language-java">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 onUpdate(BaseAdapterHelper helper, News item, int position) { helper.setText(R.id.xxx, item.getTitle()) .setImageLoad(new GlideImageLoad()) .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);

break; 更多的布局样式 ... } } }</code></pre> <p>RecyclerView item点击事件和长按事件</p> <pre> <code class="language-java">commonRecyclerAdapter.setOnItemClickListener(new CommonRecyclerAdapter.OnItemClickListener() { @Override public void onItemClick(RecyclerView.ViewHolder viewHolder, View view, int position) { // TODO ... } }); commonRecyclerAdapter.setOnItemLongClickListener(new CommonRecyclerAdapter.OnItemLongClickListener() { @Override public void onItemLongClick(RecyclerView.ViewHolder viewHolder, View view, int position) { // TODO ... } });</code></pre> <p>CommonAdapter、CommonRecyclerAdapter区别</p> <pre> <code class="language-java">CommonAdapter适用于：ListView/GridView CommonRecyclerAdapter适用于：RecyclerView 使用方式都一样</code></pre> <p>BaseAdapterHelper 使用示例</p> <pre> <code class="language-java">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) //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设置adapter .setAdapter(R.id.viewId, adapter) //下面为View常用点击事件设置 .setOnTouchListener(R.id.viewId, View.OnTouchListener) .setOnClickListener(R.id.viewId, View.OnClickListener) .setOnLongClickListener(R.id.viewId, View.OnLongClickListener) .setOnItemClickListener(R.id.viewId, AdapterView.OnItemClickListener) .setOnItemLongClickListener(R.id.viewId, AdapterView.OnItemLongClickListener) .setOnItemSelectedClickListener(R.id.viewId, AdapterView.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); </code></pre> <p>自定义图片加载</p> <pre> <code class="language-java">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 其它自定义 ... } }</code></pre> <p>注意事项</p> <pre> <code class="language-java">//加载网络图片之前，请调用setImageLoad方法，设置网络图片加载的实现类 helper.setImageLoad(new GlideImageLoad()); helper.setImageUrl(R.id.xxx,url);</code></pre> <p>常用的数据操作</p> <pre> <code class="language-java">//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(); </code></pre> <h2>感谢</h2> <p><a href="/misc/goto?guid=4959644427404037414">base-adapter-helper</a></p>
