这是点击方法

@Override
public void onClick(View v) {
int idSelec= grupoRadio.getCheckedRadioButtonId();
sexo= findViewById(idSelec);
String sex= sexo.getText().toString();
String correo= corr.getText().toString();
String pass=contra.getText().toString().trim();
switch ( v.getId() ){
case R.id.hecho_RU:
auth.createUserWithEmailAndPassword(correo,pass).addOnCompleteListener
(registroUsuarios.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(!task.isSuccessful()){
Toast.makeText(registroUsuarios.this, "Ha ocurrido un error al registrarse, inténtalo de nuevo más tarde", Toast.LENGTH_SHORT).show();
}else{
String nombre= nomb.getText().toString();
String apellido=apell.getText().toString();
String mail=corr.getText().toString();
int telefono=Integer.parseInt(tel.getText().toString());
String sex= sexo.getText().toString();
String id_usuario = auth.getCurrentUser().getUid();
DatabaseReference dbRef = FirebaseDatabase.getInstance().getReference().child("Usuarios").child(id_usuario);
Map nuevoMapa = new HashMap();
nuevoMapa.put("Nombre" ,nombre);
nuevoMapa.put("Apellido" ,apellido);
nuevoMapa.put("Correo" ,mail);
nuevoMapa.put("Telefono" ,telefono);
nuevoMapa.put("Sexo" ,sex);
dbRef.setValue(nuevoMapa);
startActivity(new Intent (registroUsuarios.this,login.class));
}
}
});
break;
case R.id.atrasRU:
finish();
break;

}
}

当我在依赖项方面遇到很多麻烦时，但一切都很好。 经过一些修改，从Firebase创建用户任务不成功甚至不知道为什么

在下面的代码下进行一些更改，从onclick中删除，我希望您在textview上设置setonclick列表。就像下面的代码..

textView=findViewById(R.id.textview);
textView.setOnClickListener(this);


int idSelec= grupoRadio.getCheckedRadioButtonId();
sexo= findViewById(idSelec);
String sex= sexo.getText().toString();
String correo= corr.getText().toString();
String pass=contra.getText().toString().trim();
