Question

每位开发人员都好，我正在一个名为e-School的项目中工作，我在使用Firebase适配器和原始操作时遇到了麻烦，我在recyclerview中有一个cardview，在该cardview上有一个“ update”和“ delete”按钮，我想触发{{1 }}和Button edit_t的图片链接位于Check Image，而Firebase结构也位于db image，但是我无法使按钮起作用需要帮助！代码如下

// TeacherViewHolder.java

Button delete_t

// TeachersAdapter.java

public class TeachersViewHolder extends RecyclerView.ViewHolder{
public CircleImageView teacherImage;
public TextView teacherName,teacherDesignation;

public TeachersViewHolder(@NonNull View itemView) {
    super(itemView);
    teacherImage = itemView.findViewById(R.id.image_teacher);
    teacherName =  itemView.findViewById(R.id.teacher_nome);
    teacherDesignation = itemView.findViewById(R.id.teacher_designation);
}}

所以伙计们，我试图摆脱这一点，我尝试编写了大量代码，最后得到了解决方案，这就是解决方案..... TeachersAdapter.java中的onBindViewHolder中有几行代码要编写，以使我们的按钮正常工作，代码如下。...下一个活动的图像链接也位于此处{ {3}}和此处clicking on update button in recyclerview

TeachersAdapter.java

       holder.edit_t.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent goUpdateTeacher = new Intent(holder.edit_t.getContext(), UpdateTeacher.class);
            goUpdateTeacher.putExtra("photourl", sTeachers.getPhotourl());
            goUpdateTeacher.putExtra("teacherName", sTeachers.getName());
            goUpdateTeacher.putExtra("teacherDesignation", sTeachers.getQualification());

            holder.edit_t.getContext().startActivity(goUpdateTeacher);
        }
    });

使用recyclerview Firebase上的按钮更新和删除
