java - 单击 Cardview 中的按钮打开对话框

Question

我是android开发的初学者，我面临的问题是，一旦我单击CardView上的编辑按钮，就不会显示警报对话框，我将在其中更新与该cardview相关的详细信息。

我尝试通过放置 Toast 来检查它是否正常工作，从而使该编辑按钮功能正常，我什至在主 Activity 中创建了一个单独的对话框，只是为了查看它是否正常工作并且它有效，但是当我调用在使用该类对象的适配器中相同，它会给出错误。

我正在从数据库中检索数据并将其转换为 Json，并且该数据使用 StringRequest 和 volley 进行网络显示在 recyclerview 的 Cardview 中

预期输出:在 Recycler View 中单击 Cardview 上的 EditButton 时，它应该向我显示一个警报或对话框，其中包含我单击并在对话框中输入的卡片的人员姓名，然后提交。

有人节省了我的时间，因为我投入了大量时间尝试..提前谢谢你

适配器代码:

@Override
public void onBindViewHolder(MyClientTrackAdapter.ViewHolder holder, int position) {
    // Find out the data, based on this view holder's position
    final ListClientTrackIssue listClient = listClients.get(position);
    holder.textViewCustomer.setText(listClient.getCustomername());
    holder.textViewcurdate.setText(listClient.getCurdate());
    holder.textViewcurtime.setText(listClient.getCurtime());
    holder.textViewtargetdate.setText(listClient.getTargetdate());
    holder.textViewtargettime.setText(listClient.getTargettime());
    holder.textViewquery.setText(listClient.getQuery());
    holder.textViewaddress.setText(listClient.getAddress());
    holder.textViewassigned.setText(listClient.getAssignedperson());
    holder.textViewcomment.setText(listClient.getComment());
    holder.textViewstatus.setText(listClient.getStatus());

    holder.editbutton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(v.getContext(),"edit"+listClient.getCustomername(),Toast.LENGTH_SHORT).show();
            new AlertDialog.Builder(context)
                    .setMessage("client"+listClient.getCustomername())
                    .setTitle("Client Status update")
                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Log.i("Result","Success");
                        }
                    })
                    .setNegativeButton("No", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Log.i("Result","Success");
                        }
                    })
                    .show();

        }

    });

}

@Override
public int getItemCount() {
    return listClients.size();
}

class ViewHolder extends RecyclerView.ViewHolder {
    Button editbutton;
    TextView textViewCustomer,textViewcurdate,textViewcurtime,textViewtargetdate,textViewtargettime,
                textViewquery,textViewaddress,textViewassigned,textViewcomment,textViewstatus;
    public ListCustomer listCustomer;

    public ViewHolder(View itemView) {
        super(itemView);

        textViewCustomer=itemView.findViewById(R.id.textViewCustomer);
        textViewcurdate=itemView.findViewById(R.id.textViewcurdate);
        textViewcurtime=itemView.findViewById(R.id.textViewcurtime);
        textViewtargetdate=itemView.findViewById(R.id.textViewtargetdate);
        textViewtargettime=itemView.findViewById(R.id.textViewtargettime);
        textViewquery=itemView.findViewById(R.id.textViewquery);
        textViewaddress=itemView.findViewById(R.id.textViewaddress);
        textViewassigned=itemView.findViewById(R.id.textViewassigned);
        textViewcomment=itemView.findViewById(R.id.textViewcomment);
        textViewstatus=itemView.findViewById(R.id.textViewstatus);

        this.editbutton=itemView.findViewById(R.id.editbtn);

主类代码:

public void showChangeLangDialog(){
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    LayoutInflater inflater = this.getLayoutInflater();
    final View dialogView = inflater.inflate(R.layout.edit_dialog, null);
    dialogBuilder.setView(dialogView);

    //final EditText edt = (EditText) dialogView.findViewById(R.id.edit1);

    dialogBuilder.setTitle("Update Client Status");
    dialogBuilder.setPositiveButton("Update", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            //do something with edt.getText().toString();
        }
    });
    dialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            //pass
        }
    });
    AlertDialog b = dialogBuilder.create();
    b.show();
}

holder.editbutton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Toast.makeText(v.getContext(),"edit"+listClient.getCustomername(),Toast.LENGTH_SHORT).show();
        new AlertDialog.Builder(v.getRootView().getContext())
                .setMessage("client"+listClient.getCustomername())
                .setTitle("Client Status update")
                .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Log.i("Result","Success");
                    }
                })
                .setNegativeButton("No", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Log.i("Result","Success");
                    }
                })
