我正在使用firebase注册我的用户，用户可以更新他们的数据，但在更新电子邮件时，他们总是向我发送任务不成功的响应，我验证了在更新邮件时它写得很好。这是代码：
`private String vPassword, vEmail;
private Button btnValidate;
private EditText edContra, edEmail;
private TextView errorContra;
private ProgressDialog pDialog;
String sMail;
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
setContentView (R.layout.activity_pop_reset_email);
pDialog = new ProgressDialog (this);
vPassword = getIntent (). getStringExtra ("password");
vEmail = getIntent (). getStringExtra ("email");
btnValidar = findViewById (R.id.btnValidar);
edContra = findViewById (R.id.passwordValidate);
edEmail = findViewById (R.id.correoValidar);
errorContra = findViewById (R.id.errorContraValidar);
DisplayMetrics measures = new DisplayMetrics ();
getWindowManager (). getDefaultDisplay (). getMetrics (measures);
int width = measurements.widthPixels;
int high = measures.heightPixels;
getWindow (). setLayout ((int) (width * 0.85), (int) (height * 0.5));
btnValidar.setOnClickListener (new View.OnClickListener () {
@Override
public void onClick (View view) {
String edPassword = edContra.getText (). ToString ();
sMail = edEmail.getText (). toString ();
if (edPassword.equals (vPassword)) {
Verify ();
} else {
errorContra.setVisibility (View.VISIBLE);
}
}
});
}
// CHECK EMAIL
private void Verify () {
if (! sCorreo.isEmpty () && sCorreo.contains ("@") && sCorreo.contains (".")) {
errorContra.setVisibility (View.INVISIBLE);
pDialog.setMessage ("Updating ...");
pDialog.setCanceledOnTouchOutside (false);
pDialog.show ();
UpdateMail ();
} else {
errorContra.setVisibility (View.VISIBLE);
errorContra.setText ("* Type Valid Mail.");
}
}
// UPDATE EMAIL
private void UpdateMail () {
FirebaseUser user = FirebaseAuth.getInstance (). GetCurrentUser ();
user.updateEmail (sMail) .addOnCompleteListener (new OnCompleteListener <Void> () {
@Override
public void onComplete (@NonNull Task <Void> task) {
if (task.isSuccessful ()) {
Toast.makeText (PopResetEmail.this, "Mail Updated", Toast.LENGTH_SHORT)
.show ();
} else {
Toast.makeText (PopResetEmail.this, "Email ERROR", Toast.LENGTH_SHORT)
.show();
}
pDialog.dismiss ();
}
});
}
// CLOSE ACTIVITY X
public void Close (View view) {
finish ();
}`
已经验证邮件更新时是否从编辑文本中获取并转换为字符串。
在我的设备上测试时，当我按下按钮更新时，这会出现在Logcast:中

如果任务不成功，调用task.getException()将向您提供错误的详细信息。所以你会想用类似的东西来显示/记录它：
user.updateEmail (sMail) .addOnCompleteListener (new OnCompleteListener <Void> () {
@Override
public void onComplete (@NonNull Task <Void> task) {
if (task.isSuccessful ()) {
Toast.makeText (PopResetEmail.this, "Mail Updated", Toast.LENGTH_SHORT).show ();
} else {
Exception e = task.getException();
Toast.makeText (PopResetEmail.this, "Error updating email: "+e.getMessage(), Toast.LENGTH_SHORT).show();
Log.w("updateEmail", "Unable to update email", e);
}
pDialog.dismiss ();
}
});
这通常足以解决故障。
