在Firebase RecyclerView Cardview中单击项目时如何打开详细信息活动

Question

我想在recyclerView中实现Onclick项目要打开新活动，我可以将数据从一个活动传递到另一活动，但是在代码中，如果有人愿意帮助我进行编辑并向Details.class提供意图，则无法确定在click onclicklistener上实现的位置。
当我第一次从Firebase上获取数据以在Firebase上工作时，我们将不胜感激。

Answer 1

在populateViewHolder中将onClickListener添加到ViewHolder的itemView中，然后启动Activity。 像下面的例子。

    @Override
    protected void populateViewHolder(MovieViewHolder viewHolder, final Movie model, final int position) {
        if(tvNoMovies.getVisibility()== View.VISIBLE){
            tvNoMovies.setVisibility(View.GONE);
        }
        viewHolder.tvMovieName.setText(model.getMovieName());
        viewHolder.address.setText(model.getAddress());
        viewHolder.phone.setText(model.getPhone());
        viewHolder.lit.setText(model.getLit());
        viewHolder.lon.setText(model.getLon());
        Picasso.with(MainActivity.this).load(model.getMoviePoster()).into(viewHolder.ivMoviePoster);

        viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this, DetailActivity.class);
                //intent.putExtra("model", model);
                intent.putExtra("latitude", model.getLit());
                intent.putExtra("longitude", model.getLon());

                startActivity(intent);
            }
        });
// all your stuff

    }

尝试这样在您的populateViewHolder添加onClickListener

@Override
        protected void populateViewHolder(MovieViewHolder viewHolder, final Movie model, final int position) {
            if(tvNoMovies.getVisibility()== View.VISIBLE){
                tvNoMovies.setVisibility(View.GONE);
            }
            viewHolder.tvMovieName.setText(model.getMovieName());
            viewHolder.address.setText(model.getAddress());
            viewHolder.phone.setText(model.getPhone());
            viewHolder.lit.setText(model.getLit());
            viewHolder.lon.setText(model.getLon());
            Picasso.with(MainActivity.this).load(model.getMoviePoster()).into(viewHolder.ivMoviePoster);
         viewHolder.tvMovieName.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MainActivity.this, DetailActivity.class);
             startActivity(intent);
        }
    });

        }
