展开式RecyclerView中的onClick(使用bignerdranch库) [英] onClick in Expandable RecyclerView (using bignerdranch library)

问题描述

在我正在工作的项目中，我得到了一堆带有问题"(子级)的项目"(父级).正如我必须在列表中显示的那样，我使用了RecyclerView来做到这一点.为此，我使用了BigNerdRanch库( https://github.com/bignerdranch/expandable-recycler-view )

In the project I'm working, I get a bunch of "Projects"(parent) with "Issues" (child). As I have to show it in a list, I used RecyclerView to do it. To achieve it I used BigNerdRanch library (https://github.com/bignerdranch/expandable-recycler-view)

问题来了，我需要单击孩子"以获取问题的所有信息并将其发送到另一活动.

The problem come's that I need to click on Child to take all the information of the issue and send it to another activity.

该库没有任何方法来处理子点击，因此我尝试实现一种解决方法并进行了工作(我认为还可以..)，但是在这里我被阻止了.我不知道如何带这个被点击的孩子来启动带有必要信息的活动.

The library don't have any method to handle the child click, so I tried to implement a work around and worked (I think is ok..), but here I'm blocked. I don't know how to take the clicked child to launch the activity with the necessary info.

这是ProjectAdapter:

Here is the 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(子级):

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());
    }
}

正如我说的那样，我对如何获取孩子的信息一无所知.

As I said,I'm stucked on How to get the child information.

我该如何解决?

推荐答案

  @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
                    }
                });
    }
