问题描述
如何实施 RecyclerView onItemClick 监听器，因为我们做的ListView，这是用我的旧的适配器类的ListView ：
公共类GenreAdapter延伸BaseAdapter {....@覆盖
公共查看getView（最终诠释的立场，观点convertView，父母的ViewGroup）{
//转换视图=设计
视图V = convertView;
如果（V == NULL）{
持有人=新ViewHolder（）;
V = vi.inflate（资源，NULL）;
holder.textTitle =（TextView中）v.findViewById（R.id.textTitle）;
v.setTag（保持器）;
}其他{
支架=（ViewHolder）v.getTag（）;
} holder.textTitle.setText（genreArrayList.get（位置）.getTitle（））; v.setOnClickListener（新OnClickListener（）{ @覆盖
公共无效的onClick（视图v）{ 束束=新包（）;
bundle.putSerializable（数据，genreArrayList）;
bundle.putInt（当前，位置）; 意向意图=新意图（背景下，MovieActivity.class）;
intent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
intent.putExtras（包）;
context.startActivity（意向）; }
}）; 返回伏;
}静态类ViewHolder {
公众的TextView textTitle;
}
MainFragment.java： -
@覆盖
公共查看onCreateView（LayoutInflater充气器，容器的ViewGroup，捆绑savedInstanceState）{
鉴于= inflater.inflate（R.layout.fragment_main，集装箱，FALSE）; / *初始化回收视图* /
mRecyclerView =（RecyclerView）view.findViewById（R.id.recycler_view）;
mRecyclerView.setLayoutManager（新LinearLayoutManager（getActivity（）））; mRecyclerView.addItemDecoration（新DividerItemDecoration（getActivity（），DividerItemDecoration.VERTICAL_LIST））; 名单=新的ArrayList＆LT; MainPoho＆GT;（）;
适配器=新MainAdapter（getActivity（），清单）;
mRecyclerView.setAdapter（适配器）; .......}
这是用我的新的适配器类 RecyclerView ：
公共类MyRecyclerAdapter扩展RecyclerView.Adapter＆LT; FeedListRowHolder＆GT; { 私人列表＆LT; FeedItem＆GT; feedItemList;
私人语境mContext; 公共MyRecyclerAdapter（上下文的背景下，列表与LT; FeedItem＆GT; feedItemList）{
this.feedItemList = feedItemList;
this.mContext =背景;
} @覆盖
公共FeedListRowHolder onCreateViewHolder（ViewGroup中ViewGroup中，int i）以{
视图V = LayoutInflater.from（viewGroup.getContext（））膨胀（R.layout.list_row，NULL）;
FeedListRowHolder MH =新FeedListRowHolder（V）;
返回MH;
} @覆盖
公共无效onBindViewHolder（FeedListRowHolder feedListRowHolder，int i）以{
FeedItem feedItem = feedItemList.get（ⅰ）;
feedListRowHolder.title.setText（Html.fromHtml（feedItem.getTitle（）））;
} @覆盖
公众诠释getItemCount（）{
如果（feedItemList！= NULL）{
返回feedItemList.size（）;
}其他{
返回0;
}
}
公共类FeedListRowHolder扩展RecyclerView.ViewHolder {
保护TextView的称号; 公共FeedListRowHolder（查看视图）{
超（视图）;
this.title =（TextView中）view.findViewById（R.id.title）;
}
FeedItem.java： -
公共类FeedItem {
私人字符串称号; 公共字符串的getTitle（）{
返回称号;
} 公共无效的setTitle（字符串名称）{
this.title =称号;
}}
解决方案
在您viewHolder第一家店全视图：
公共类FeedListRowHolder扩展RecyclerView.ViewHolder {
保护TextView的称号;
受保护的视图mRootView; 公共FeedListRowHolder（查看视图）{
超（视图）;
this.title =（TextView中）view.findViewById（R.id.title）;
mRootView =视图。
}
然后点击设置在监听 onBindViewHolder ：
@覆盖
公共无效onBindViewHolder（FeedListRowHolder feedListRowHolder，int i）以{
FeedItem feedItem = feedItemList.get（ⅰ）;
feedListRowHolder.title.setText（Html.fromHtml（feedItem.getTitle（）））;
feedListRowHolder.mRootView.setOnClickListener（新OnClickListener（）{ @覆盖
公共无效的onClick（视图v）{ }
}）;
}
How to implement RecyclerView onItemClick listener as we do with ListView, this is my old Adapter class using ListView:
public class GenreAdapter extends BaseAdapter {
....
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// convert view = design
View v = convertView;
if (v == null) {
holder = new ViewHolder();
v = vi.inflate(Resource, null);
holder.textTitle = (TextView) v.findViewById(R.id.textTitle);
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
holder.textTitle.setText(genreArrayList.get(position).getTitle());
v.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Bundle bundle = new Bundle();
bundle.putSerializable("data", genreArrayList);
bundle.putInt("current", position);
Intent intent = new Intent(context, MovieActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtras(bundle);
context.startActivity(intent);
}
});
return v;
}
static class ViewHolder {
public TextView textTitle;
}
MainFragment.java:-
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_main, container, false);
/* Initialize recycler view */
mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
mRecyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), DividerItemDecoration.VERTICAL_LIST));
list = new ArrayList<MainPoho>();
adapter = new MainAdapter(getActivity(), list);
mRecyclerView.setAdapter(adapter);
.......
}
And here is my new Adapter class using RecyclerView :
public class MyRecyclerAdapter extends RecyclerView.Adapter<FeedListRowHolder> {
private List<FeedItem> feedItemList;
private Context mContext;
public MyRecyclerAdapter(Context context, List<FeedItem> feedItemList) {
this.feedItemList = feedItemList;
this.mContext = context;
}
@Override
public FeedListRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_row, null);
FeedListRowHolder mh = new FeedListRowHolder(v);
return mh;
}
@Override
public void onBindViewHolder(FeedListRowHolder feedListRowHolder, int i) {
FeedItem feedItem = feedItemList.get(i);
feedListRowHolder.title.setText(Html.fromHtml(feedItem.getTitle()));
}
@Override
public int getItemCount() {
if(feedItemList !=null){
return feedItemList.size();
} else {
return 0;
}
}
public class FeedListRowHolder extends RecyclerView.ViewHolder {
protected TextView title;
public FeedListRowHolder(View view) {
super(view);
this.title = (TextView) view.findViewById(R.id.title);
}
FeedItem.java:-
public class FeedItem {
private String title;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
解决方案
first store whole view in your viewHolder:
public class FeedListRowHolder extends RecyclerView.ViewHolder {
protected TextView title;
protected View mRootView;
public FeedListRowHolder(View view) {
super(view);
this.title = (TextView) view.findViewById(R.id.title);
mRootView = view;
}
then set click listener at onBindViewHolder:
@Override
public void onBindViewHolder(FeedListRowHolder feedListRowHolder, int i) {
FeedItem feedItem = feedItemList.get(i);
feedListRowHolder.title.setText(Html.fromHtml(feedItem.getTitle()));
feedListRowHolder.mRootView.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
}
});
}
