Question

在我工作的项目中，我得到了一堆＆＃34;项目＆＃34;（父母）与＆＃34;问题＆＃34; （儿童）。由于我必须在列表中显示它，我使用RecyclerView来完成它。为了实现它，我使用了BigNerdRanch库（https://github.com/bignerdranch/expandable-recycler-view）

问题是，我需要点击Child以获取问题的所有信息并将其发送到另一个活动。

图书馆没有任何方法可以处理儿童点击，所以我尝试实施一个工作并且工作（我认为没问题。），但是这里我被阻止了。我不知道如何让点击的孩子用必要的信息启动活动。

这是ProjectAdapter：

public class ProjectAdapter extends ExpandableRecyclerAdapter<ProjectViewHolder, IssueViewHolder> {

    private LayoutInflater mInflator;
    private Context appContext ;

    public ProjectAdapter(Context context, @NonNull List<? extends ParentListItem> parentItemList) {
        super(parentItemList);
        this.mInflator = LayoutInflater.from(context);
        this.appContext = context;
    }

    @Override
    public ProjectViewHolder onCreateParentViewHolder(ViewGroup parentViewGroup) {
        View projectView = mInflator.inflate(R.layout.jira_project, parentViewGroup, false);
        return new ProjectViewHolder(projectView);
    }

    @Override
    public IssueViewHolder onCreateChildViewHolder(ViewGroup childViewGroup) {
        View issueView = mInflator.inflate(R.layout.jira_issue, childViewGroup, false);
        return new IssueViewHolder(issueView,this.appContext);
    }

    @Override
    public void onBindParentViewHolder(ProjectViewHolder projectViewHolder, int position, ParentListItem parentListItem) {
        Project project = (Project) parentListItem;
        projectViewHolder.bind(project);
    }

    @Override
    public void onBindChildViewHolder(IssueViewHolder issueViewHolder, int position, Object childListItem) {
        Issue issue = (Issue) childListItem;
        issueViewHolder.bind(issue);
    }
}

IssueViewHolder（Child）：

public class IssueViewHolder extends ChildViewHolder{

    private TextView mIssueTextView; // contendra de momento el "summary" del issue
    private Context appContext;

    public IssueViewHolder(View itemView, final Context appContext) {
        super(itemView);
        this.appContext = appContext;
        this.mIssueTextView = (TextView) itemView.findViewById(R.id.jir_issue_name);
        this.mIssueTextView.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {
                Log.d("JIRA", "CLICk CHILD");
                Toast.makeText(appContext, "CHILD #"+getAdapterPosition() +"\n CHILD##"+getPosition(), Toast.LENGTH_LONG).show();
            }
        });
    }

    public void bind(Issue issue){
        mIssueTextView.setText(issue.getKey());
    }
}

正如我所说，我一直在坚持如何获取儿童信息。

我该如何解决？

  @Override
    public void onBindChildViewHolder(IssueViewHolder issueViewHolder, int position, Object childListItem) {
        Issue issue = (Issue) childListItem;
        issueViewHolder.bind(issue);

      issueViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        //your code
                    }
                });
    }

onClick在Expandable RecyclerView中（使用bignerdranch库）
