每个recycleview项中的java可点击字符串数组项

Question

我有一个API，其中包含如下数据：

{"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parcelable课程中，我为标题做了以下工作：

public String getTitles() {
        return titles;
    }

    public StringBuilder getFullTitles() {

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

下面是url：

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中获取如下标题数据：

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

我在我的recycleview应用程序中得到的结果如下：

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

现在你可以看到这个群体：

1title1
1title2
1title3

请参阅recycleview的第一项 这群人：

2title1
2title2
2title3

请参阅recycleview的第二项

你可以将其与api进行比较，以理解我的意思

我需要做的是使每组的每个项目都适用于被点击

比如当我点击1title1时，我得到了与标题相对应的url，它是1url1，可以在youtube上打开它 当我点击1title2时，我得到了与标题相对应的url，它是1url2，可以在youtube上打开它 当我点击2title2时，我得到了与标题相对应的url，它是2url2，可以在youtube上打开它

等等

这就像在recycleview的每个主要项目中单击项目一样

以下是尝试回答后的代码：

@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
            }
        });

    }

这是系列列表项的完整代码。xml:

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

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

    <TextView
        安卓:id="@+id/url"
        安卓:layout_width="wrap_content"
        安卓:layout_height="wrap_content"
        安卓:textColor="#fff"
        安卓:textSize="14sp"
        安卓: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();
    }

}

和可包裹类：

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;
    }

}

当我点击上面的代码来测试点击项目时，我只是试图显示一条toast消息 但如果我想在我点击标题时像现在一样，那么同一个项目的url开始播放 我如何处理这个点击？在适配器本身还是在活动中

Answer 1

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

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
            }
        }
    }
