向Firestore发送电子邮件时出现不支持的类型错误

Question

我在将数据(姓名、姓氏、电子邮件(保存到FireStore数据库时遇到问题。授权运行良好，正在添加新用户。但我想把AndroidStudio的EditText类型中的这3个变量保存为Firebase的新文档。但控制台中突然出现错误：

Process: com.example.poduszkowoapp, PID: 7276
java.lang.IllegalArgumentException: Invalid data. Unsupported type: androidx.appcompat.widget.AppCompatEditText (found in field Email)

出现问题的注册活动中本节的代码：

fAuth.createUserWithEmailAndPassword(txtEmail.getText().toString(),txtPassword.getText().toString()).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(task.isSuccessful())
{
userID = fAuth.getCurrentUser().getUid();
Map<String, Object> userMap = new HashMap<>();
userMap.put("Name", txtName);
userMap.put("Surname", txtSurname);
userMap.put("Email", txtEmail);
fStore.collection("users").document(userID).set(userMap).addOnSuccessListener(new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void aVoid) {
Toast.makeText(RegisterActivity.this, "Registered succesfully", Toast.LENGTH_SHORT).show();
startActivity(new Intent(getApplicationContext(), MainActivity.class));
finish();
}
});
}
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
if(e instanceof FirebaseAuthUserCollisionException)
{
Toast.makeText(RegisterActivity.this, "This email address is already taken", Toast.LENGTH_LONG).show();
}
}
});

Answer 1

看起来您正在将Android视图的实例传递给Firestore:

Map<String, Object> userMap = new HashMap<>();
userMap.put("Name", txtName);
userMap.put("Surname", txtSurname);
userMap.put("Email", txtEmail);

如果txtEmail和其他对象是Android视图对象，那么这根本不起作用。Firestore对Android视图一无所知。您必须编写代码从小部件中提取字符串值，并将这些字符串传递给Firestore。例如，要从EditText:中获取字符串

userMap.put("Email", txtEmail.getText().toString());

Answer 2

让你的地图是：

Map<String, Object> userMap = new HashMap<>();
userMap.put("Name", txtName.getText().toString());
userMap.put("Surname", txtSurname.getText().toString());
userMap.put("Email", txtEmail.getText().toString());

您正在将您的EditText类型写入firestore，而不是其中的文本。
