Question

我是使用Firebase进行Android开发的新手。我不愿意将意图传递给新活动。我想在回收站视图中点击特定卡片时将url和url1传递给新活动。

这是我的代码

MainActivity

    myRef = FirebaseDatabase.getInstance().getReference("project").child("electronics");
    recyclerView = (RecyclerView) findViewById(R.id.recycle);
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));


    FirebaseRecyclerAdapter<Project,BlogViewHolder> adapter = new FirebaseRecyclerAdapter<Project, BlogViewHolder>(
            Project.class,
            R.layout.card,
            BlogViewHolder.class,
            myRef
    ) {
        @Override
        protected void populateViewHolder(BlogViewHolder viewHolder, Project model, int position) {

            viewHolder.setProjectName(model.getProjectName());
            viewHolder.setUrl1(model.getUrl1());

            progressDialog.hide();
        }

    };

    recyclerView.setAdapter(adapter);

}

public  static class BlogViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    TextView project1;
    ImageView imageview;

    public BlogViewHolder(View itemView) {
        super(itemView);
        itemView.setOnClickListener(this);
        project1 = itemView.findViewById(R.id.textView);
        imageview = itemView.findViewById(R.id.projectImage);

    }

    public void setProjectName(String projectName) {
        project1.setText(projectName);
    }

    public void setUrl1(String url1) {
        Picasso.with(itemView.getContext())
                .load(url1)
                .into(imageview);
    }

Project.java

public class Project {
private  String projectName,url,url1;

public Project() {
}

public Project(String projectName, String url, String url1) {
    this.projectName = projectName;
    this.url = url;
    this.url1 = url1;
}

public String getProjectName() {
    return projectName;
}

public void setProjectName(String projectName) {
    this.projectName = projectName;
}

public String getUrl() {
    return url;
}

public void setUrl(String url) {
    this.url = url;
}

public String getUrl1() {
    return url1;
}

public void setUrl1(String url1) {
    this.url1 = url1;
}}

包。

你在String中得到model.getUrl（）并使用bundle来传递你想要的东西。

方法

中的

Triangle result = new Triangle(10,10,10);

并在你的nextActivity中，你需要抓住你的捆绑包。

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case xxxx:
            Intent intent = new Intent(mActivity, nextActivity.class);
            Bundle bundle = new Bundle();
            String value = model.getUrl();
            bundle.putString(key, value);
            intent.putExtras(bundle);
            startActivity(intent);
            break;
    }
}

如何将Intent传递给firebase recyclerview的新活动
