每个recycleview项目中的可点击字符串数组项目

我有一个具有如下数据的API：

{"seasons":[
{
"id":"1",
"titles":"1title1;1title2;1title3",
"url":"1url1;1url2;1url3;"
},
{
"id":"2",
"titles":"2title1;2title2;2title3",
"url":"2url1;2url2;2url3;"
}
]}

我很好地解析了它，在包裹类中，我这样做是为了标题：

public String getTitles() {
        return titles;
    }

    public StringBuilder getFullTitles() {

        StringBuilder builder = new StringBuilder();
        String[] titlesArray = getTitles().split(";");
        for (String title : titlesArray) {
            builder.append(title + "\n");
        }

这是网址：

public String getUrlAdaptive() {
        return urladaptive;
    }

    public StringBuilder getFullUrlAdaptiveFinal() {

        StringBuilder builder2 = new StringBuilder();
        String[] urlArray = getUrlAdaptive().split(";");
        for (String details : urlArray) {
            builder2.append(details + "\n");
        }
        return builder2;
    }

因此，在我的recycleview适配器中，我在textview中获取标题数据，如下所示：

@Override
    public void onBindViewHolder(RecyclerViewHolder holder, int position) {
        holder.title.setText(String.valueOf(mMoviesItems.get(position).getFullTitles()));    
    }

而我在recycleview应用程序中得到的结果是这样的：

1title1
1title2
1title3
2title1
2title2
2title3

现在您可以看到该组：

1title1
1title2
1title3

请参阅recycleview的第一项 和这个小组：

2title1
2title2
2title3

请参阅recycleview的第二项

您可以将其与api进行比较以了解我的意思

我需要做的是使每个组的每个项目都可以被点击

就像当我单击 1title1 时一样，我获得了与该标题对应的网址，即 1url1 在youtube中打开 当我点击 1title2 时，我得到了与该标题对应的网址，即 1url2 在youtube中打开 当我点击 2title2 时，我得到了与该标题对应的网址，即 2url2 可以在youtube中打开它

以此类推

就像在recycleview的每个主要项目中的点击项目一样

这是尝试答案后的代码：

@Override
    public void onBindViewHolder(final RecyclerViewHolder holder, final int position) {
        holder.title.setText(String.valueOf(mMoviesItems.get(position).getFullTitles()));

        holder.title.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View vview) {
                // here when click on each title I need to get the getFullUrlAdaptiveFinal with it to play it
            }
        });

    }

这是series_list_item.xml的完整代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#21293B"
    android:orientation="vertical">

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#fff"
        android:textSize="14sp"
        android:visibility="visible" />

    <TextView
        android:id="@+id/url"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#fff"
        android:textSize="14sp"
        android:visibility="visible" />

</LinearLayout>

适配器代码：

public class SeriesAdapter extends RecyclerView.Adapter<SeriesAdapter.RecyclerViewHolder> {

        ArrayList<SeriesItem> mMoviesItems;
        private Context context;
        private SeriesAdapterOnClickHandler mClickHandler;

public interface SeriesAdapterOnClickHandler {
    void onClick(SeriesItem movie);
}

    public SeriesAdapter(SeriesAdapterOnClickHandler clickHandler) {
        mClickHandler = clickHandler;
    }

    public void setClickListener(SeriesAdapterOnClickHandler callback) {
        mClickHandler = callback;
    }

class RecyclerViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    public final TextView SeriesSeasontitle;
    public final TextView urlAdaptive;

    public RecyclerViewHolder(View view) {
        super(view);
        SeriesSeasontitle = (TextView)itemView.findViewById(R.id.title);
        urlAdaptive = (TextView)itemView.findViewById(R.id.url);
        view.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        int adapterPosition = getAdapterPosition();
        SeriesItem movie = mMoviesItems.get(adapterPosition);
        String text = "already Added To Favorites";
                Toast.makeText(context, text, Toast.LENGTH_LONG).show();
        mClickHandler.onClick(movie);
    }

}

    @Override
    public RecyclerViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
        context = viewGroup.getContext();
        int layoutIdForListItem = R.layout.series_list_item;
        LayoutInflater inflater = LayoutInflater.from(context);
        boolean shouldAttachToParentImmediately = false;

        View view = inflater.inflate(layoutIdForListItem, viewGroup, shouldAttachToParentImmediately);

        RecyclerViewHolder holder = new RecyclerViewHolder(view);

        return new RecyclerViewHolder(view);
    }

    @Override
    public void onBindViewHolder(final RecyclerViewHolder holder, final int position) {
        holder.SeriesSeasontitle.setText(String.valueOf(mMoviesItems.get(position).getFullTitles()));

        holder.SeriesSeasontitle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View vview) {
                String text = "text";
                Toast.makeText(context, text, Toast.LENGTH_LONG).show();
            }
        });

    }

    @Override
    public int getItemCount() {
        if (null == mMoviesItems)
            return 0;
        else {
            return mMoviesItems.size();
        }
    }

    @Override
    public int getItemViewType(int position) {
        if (null == mMoviesItems)
            return 0;
        else {
            return mMoviesItems.size();
        }
    }

    public void setMovieData(ArrayList<SeriesItem> movieData) {
        mMoviesItems = movieData;
        notifyDataSetChanged();
    }
}

活动代码：

SeriesDetail extends AppCompatActivity implements
        SeriesAdapter.SeriesAdapterOnClickHandler {

    SeriesAdapter mAdapterTrailer;
    RecyclerViewAdapterOthers mAdapterOthers;

    @BindView(R.id.rv_videos)
    RecyclerView mVideosList;

    @BindView(R.id.tv_error_message_display3)
    TextView mErrorMessageDisplay3;

    @BindView(R.id.rv_videos2)
    RecyclerView mTrailersList;
    @BindView(R.id.pb_loading_indicator_trailers2)
    ProgressBar mLoadingIndicatorTrailers2;

    String sortOrder2="seasons/1435";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_series_detail);

        ButterKnife.bind(this);


        LinearLayoutManager LayoutManager2 = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
        mTrailersList.setLayoutManager(LayoutManager2);
        mTrailersList.setHasFixedSize(true);
        mAdapterTrailer = new SeriesAdapter(this);
        mTrailersList.setAdapter(mAdapterTrailer);

        loadVideosData(String.valueOf(sortOrder2));

    }


    private void loadVideosData(String movieId) {
        showVideoDataView();
        new FetchVideosTask().execute(movieId);
    }


    @Override
    public void onClick(SeriesItem video) {

    }


    private void showTrailerDataView() {
        mErrorMessageDisplay3.setVisibility(View.INVISIBLE);
        mTrailersList.setVisibility(View.VISIBLE);
    }

    private void showErrorMessage3() {
        mTrailersList.setVisibility(View.INVISIBLE);
        mErrorMessageDisplay3.setVisibility(View.VISIBLE);
    }

    public class FetchVideosTask extends AsyncTask<String, Void, ArrayList<SeriesItem>> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            mLoadingIndicatorTrailers2.setVisibility(View.VISIBLE);
        }

        @Override
        protected ArrayList<SeriesItem> doInBackground(String... params) {
            if (params.length == 0) {
                return null;
            }
            String movieId = params[0];
            URL videosRequestUrl = NetworkSeries.buildUrl(movieId);

            try {
                String jsonVideoResponse = NetworkSeries.getResponseFromHttpUrl(videosRequestUrl);

                ArrayList<SeriesItem> simpleJsonVideoData = JsonShashaDetailSeries.getSimpleMovieStringsFromJson(SeriesDetail.this, jsonVideoResponse);

                return simpleJsonVideoData;

            } catch (Exception e) {
                e.printStackTrace();
                return null;
            }
        }

        @Override
        protected void onPostExecute(ArrayList<SeriesItem> videoData) {
            mLoadingIndicatorTrailers2.setVisibility(View.INVISIBLE);
            if (videoData != null) {
                showTrailerDataView();
                mAdapterTrailer.setMovieData(videoData);
            } else {
                showErrorMessage3();
            }
        }
    }


    @Override
    protected void onStart() {
        super.onStart();
    }

}

和可拆分类：

public class SeriesItem implements Parcelable {

    private String titles;
    private String urladaptive;

    public SeriesItem(String titles, String urladaptive) {
        this.titles = titles;
        this.urladaptive = urladaptive;
    }

    @Override
    public void writeToParcel(Parcel out, int flags) {
        out.writeString(titles);
        out.writeString(urladaptive);
    }

    private SeriesItem(Parcel in) {
        this.titles         = in.readString();
        this.urladaptive         = in.readString();
    }

    public SeriesItem() {
    }

    @Override
    public int describeContents() {
        return 0;
    }

    public static final Creator<SeriesItem> CREATOR = new Creator<SeriesItem>() {
        @Override
        public SeriesItem createFromParcel(Parcel in) {
            return new SeriesItem(in);
        }
        @Override
        public SeriesItem[] newArray(int i) {
            return new SeriesItem[i];
        }
    };


    public String getTitles() {
        return titles;
    }

    public StringBuilder getFullTitles() {

        StringBuilder builder = new StringBuilder();
        String[] titlesArray = getTitles().split(";");
        for (String details : titlesArray) {
            builder.append(details + "\n");
        }

        return builder;
    }


    public String getUrlAdaptive() {
        return urladaptive;
    }

    public StringBuilder getFullUrlAdaptiveFinal() {

        StringBuilder builder2 = new StringBuilder();
        String[] urlArray = getUrlAdaptive().split(";");
        for (String details : urlArray) {
            builder2.append(details + "\n");
        }
        return builder2;
    }

}

当我单击上面的代码以测试项目的点击时，我只是尝试显示一条吐司消息，并且它可以工作 但是如果我想像现在这样单击标题时，则开始播放相同项目的网址 我如何处理此点击？在适配器本身还是活动中？

是的，这是可能的。只需使用OnClickListener并将其设置在onBindViewHolder（）中即可。

它看起来像这样：

@Override
    public void onBindViewHolder(RecyclerViewHolder holder, int position) {
        holder.title.setText(String.valueOf(mMoviesItems.get(position).getFullTitles()));
        holder.title.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                 // Toast here
            }
        }
    }
