Question

我有一个带有单选按钮的回收视图，目的是在用户选择“不合适的”单选按钮时弹出一个对话框（对话框），从中出现选项，并基于用户从这些选项中的选择，将会打开一个新活动，其中包含来自recyclerview的信息。

到目前为止，我已经能够进行对话和活动了，但是我遇到的一个问题是将数据从recyclerview导入到新活动中。

我读过类似的主题，没有人得到我需要的答案。

RecyclerView Click to pass data to new activity

主要活动

////Firebase Adapter and related properties

        FirebaseRecyclerOptions<Drugs> options = new FirebaseRecyclerOptions.Builder<Drugs>()
                .setQuery(query, Drugs.class).build();

        adapter = new FirebaseRecyclerAdapter<Drugs, DrugsViewHolder>(options) {
            @Override

                holder.setDiag2(model.getGeneric());
                holder.setDiag3(model.getDose());

任何有关我应如何进行的想法或建议或链接，将不胜感激。

Answer 1

RecyclerView应该通过简单地将输入参数传递到显示AlertDialog的方法中来将信息传递给AlertDialog。然后，AlertDialog可以使用Intent Extras将数据传递到下一个Activity。

DrugsViewHolder(@NonNull View itemView) {
    super(itemView);
    mView = itemView;
    RadioButton radioButton = mView.findViewById(appropraite);
    radioButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //open AlertDialog
        }
    });


}

Answer 2

您没有设置其他目的例如您要将“这是一个示例数据”发送到另一个活动

grep -o '\<WORD\>' | wc -l

在ADR活动中：

//set data int current activity
Intent intent = new Intent(getApplicationContext(),ADR.class);
intent.putExtra("key","this is a sample data");
startActivity(intent);

我希望这对您有帮助
