com.google.firebase.database.DatabaseException: Found two getters or fields with conflicting case sensitivity for property.
这是我的代码signupTeacherActivity:
this is my code signupTeacherActivity:
public class signupTeacher extends AppCompatActivity {
EditText userfirstname,userlastname, useremail,userpassword,userconfirmpassword, CV,city;
private DatabaseReference mDatabase;
private FirebaseAuth mAuth;
Spinner spinner;
String defaultuserprofileimg;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup_teacher);
getSupportActionBar().setTitle("Sign Up");
findViewByIds();
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.subject_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
}
public void signUpUser(View view) {
if(useremail.getText().toString().length()==0 || userpassword.getText().toString().length()==0||userfirstname.getText().length()==0 ||userconfirmpassword.getText().length()==0 ||userlastname.getText().length()==0){
Toast.makeText(signupTeacher.this, "Please enter all the fields to proceed further.",
Toast.LENGTH_SHORT).show();
}else {
if(spinner.getSelectedItem().toString().equals("Select a Subject")){
Toast.makeText(signupTeacher.this, "Please select a valid Subject.", Toast.LENGTH_LONG).show();
}
else {
mAuth = FirebaseAuth.getInstance();
mAuth.createUserWithEmailAndPassword(useremail.getText().toString(), userpassword.getText().toString())
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d("demo", "createUserWithEmail:onComplete:" + task.isSuccessful());
if (!task.isSuccessful()) {
Toast.makeText(signupTeacher.this, task.getException().toString(),
Toast.LENGTH_SHORT).show();
} else {
mDatabase = FirebaseDatabase.getInstance().getReference();
Teacher user = new Teacher(userfirstname.getText().toString(), userlastname.getText().toString(), useremail.getText().toString(), userpassword.getText().toString() , CV.getText().toString(), spinner.getSelectedItem().toString(), city.getText().toString(),task.getResult().getUser().getUid().toString(), defaultuserprofileimg);
mDatabase.child("Teachers").child(task.getResult().getUser().getUid().toString()).setValue(user);
Intent i = new Intent(signupTeacher.this, MainActivity.class);
startActivity(i);
Toast.makeText(signupTeacher.this, "Succesfully registered. Please login with the created credentials",
Toast.LENGTH_LONG).show();
mAuth = FirebaseAuth.getInstance();
mAuth.signOut();
finish();
}
}
});
}
}
}
public void goToLogin(View view) {
Intent i=new Intent(signupTeacher.this,MainActivity.class);
startActivity(i);
finish();
}
private void findViewByIds() {
userfirstname= (EditText)findViewById(R.id.firstname);
userlastname= (EditText) findViewById(R.id.lastname);
userpassword= (EditText) findViewById(R.id.password);
userconfirmpassword= (EditText)findViewById(R.id.confirmpassword);
useremail= (EditText) findViewById(R.id.email);
spinner = (Spinner) findViewById(R.id.spSubject);
CV = (EditText) findViewById(R.id.cv);
city = (EditText) findViewById(R.id.City);
}}
我的班主任:
public class Teacher implements Serializable {
String firstlame,lastname,useremail,userpassword, CV, spinner, city, userkey,userimageuri;
public String getFirstlame() {
return firstlame;
}
public void setFirstlame(String firstlame) {
this.firstlame = firstlame;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getUseremail() {
return useremail;
}
public void setUseremail(String useremail) {
this.useremail = useremail;
}
public String getUserpassword() {
return userpassword;
}
public void setUserpassword(String userpassword) {
this.userpassword = userpassword;
}
public String getCv() {
return CV;
}
public void setCv(String CV) {
this.CV = CV;
}
public String getSpinner() {
return spinner;
}
public void setSpinner(String spinner) {
this.spinner = spinner;
}
public String getCity() {return city; }
public void setCity(String city) {
this.city = city;
}
public String getUserkey() {
return userkey;
}
public void setUserkey(String userkey) {
this.userkey = userkey;
}
public String getUserimageuri() {
return userimageuri;
}
public void setUserimageuri(String userimageuri) {
this.userimageuri = userimageuri;
}
public Teacher(String firstlame, String lastname, String useremail, String userpassword, String CV, String spSubject , String City, String userkey, String userimageuri ) {
this.firstlame = firstlame;
this.lastname = lastname;
this.useremail = useremail;
this.userpassword = userpassword;
this.CV = CV;
this.spinner = spSubject;
this.city = City;
this.userkey=userkey;
this.userimageuri=userimageuri;
}
public Teacher(){
}}

推荐答案
尝试修复字段和方法的大写字母. firstName，getFirstName ...等等
Try to fix the capitalization on your fields and methods. firstName, getFirstName... etc
您的错误是在CV字段上，该方法应为setCV以匹配该字段的大小写，不过，您应该在Java命名争用之后将其命名为cv.然后方法是get或setCv
Your error is on the CV field, where the method should be setCV to match the case of the field, though, you should name it cv following Java naming contentions. And the method is then get or setCv
public String getCv() {
return cv;
}
public void setCv(String cv) {
this.cv = cv;
}
我还建议不要将密码存储为对象的一部分.特别是如果它们是纯文本.您将密码发送到数据库以检查有效性或进行更新；将它们读出并保留在其他地方很少是一个好主意
I would also suggest not storing passwords as part of your objects. Especially if they are plain text. You send passwords to the database to check for validity or to update; it's seldom a good idea to read them out and persist them elsewhere
