当我尝试创建新帐户时，创建帐户按钮不会在android studio中触发而不会进入下一个活动，即使屏幕上没有显示错误消息。请帮我解决这个问题。
这是Kotlin版本以及当用户没有填写下面提到的任何字段时如何显示错误消息。
class RegisterActivity : AppCompatActivity( ) {
var mAuth: FirebaseAuth? = null
var mDatabase: DatabaseReference? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_register)
mAuth = FirebaseAuth.getInstance()
createaccountET.setOnClickListener {
val name = accountdisplaynameET.text.toString().trim()
val email = registeremailET.text.toString().trim()
val password = registerpasswordET.text.toString().trim()
val reenterpassword = reenterpasswordET.text.toString().trim()
val Mobile = mobilenumberET.text.toString().trim()
val date = dateofbirthET.text.toString().trim()
val gender = genderET.text.toString().trim()

}
}
