如何在Firebase Android应用程序中分隔两个不同的用户? [英] How to separate two different user in firebase android app?
问题描述
我有一个具有两种不同类型用户的应用程序，一种是教师"，另一种是普通用户.如果普通成员登录，则将转到normal_memberActivity；如果是教师成员，则将转到Teacher_memberActivity.如何在loginActivity中做到这一点?

我的Firebase结构:
My Firebase structure:
这是数据库Firebase规则
this is database firebase rules

}
推荐答案
我已经解决了一个星期的问题.很抱歉，上述提议的解决方案有点误导.因此，我对此有一个更好的解决方案，它的101％可行！
i have been solving this problem for a week. I'm sorry to say the solution proposed above is kinda misleading. Thus, i have a better solution for this, and its 101% workable !
首先，这是我在Firebase中的实时数据库: 我为创建的每种用户类型创建了一个子类型. 然后，在类型"子项的值内，我将卖方帐户设置为1，将买方帐户设置为2.
First, this is my real-time database in Firebase: I created a child "type" for each type of users created. Then, i set seller's account as 1 and buyer's account as 2 inside the "type" child's value.
第二，在我成功验证了登录详细信息之后. 在那一刻，我使用firebase实时数据快照根据当前用户的身份提取类型值. UID，然后验证值等于1还是2.最后，我能够根据用户类型启动活动.
Second, after i successfully verified the login details. At that particular moment, i use the firebase real-time datasnapshot to pull the type value based on the current user's UID, then i verified whether is the value is equal to 1 or 2. Finally i able to start the activity based on the type of user.
帐户创建代码:
private void registerUser() {
progressDialog = new ProgressDialog(this);
String email = editTextEmail.getText().toString().trim();
String password = editTextPassword.getText().toString().trim();
if (TextUtils.isEmpty(email)) {
Toast.makeText(this, "Please Enter Emailsss", Toast.LENGTH_SHORT).show();
return;
}
if (TextUtils.isEmpty(password)) {
Toast.makeText(this, "Please Enter Your PASSWORDS", Toast.LENGTH_SHORT).show();
return;
}
progressDialog.setMessage("Registering User Statement..");
progressDialog.show();
//Firebase authentication (account save)
firebaseAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
//user already logged in
//start the activity
finish();
onAuthSuccess(task.getResult().getUser());
// startActivity(new Intent(getApplicationContext(), MainActivity.class));
} else {
Toast.makeText(signupActivity.this, "Could not registered , bullcraps", Toast.LENGTH_SHORT).show();
}
progressDialog.dismiss();
}
});
}
private void onAuthSuccess(FirebaseUser user) {
//String username = usernameFromEmail(user.getEmail());
// Write new user
writeNewUser(user.getUid(), toggle_val, user.getEmail());
// Go to MainActivity
startActivity(new Intent(signupActivity.this, MainActivity.class));
finish();
}
private void writeNewUser(String userId, int type, String email) {
User user = new User(Integer.toString(type), email);
if (type == 1){
mDatabase.child("users").child(userId).setValue(user);
}
else {
mDatabase.child("users").child(userId).setValue(user);
}
}
if (toggleBut.isChecked()){
toggle_val = 2;
//Toast.makeText(signupActivity.this, "You're Buyer", Toast.LENGTH_SHORT).show();
}
else{
toggle_val = 1;
//Toast.makeText(signupActivity.this, "You're Seller", Toast.LENGTH_SHORT).show();
}
登录帐户代码:
private void userLogin () {
String email = editTextEmail.getText().toString().trim();
String password = editTextPassword.getText().toString().trim();
if(TextUtils.isEmpty(email)){
Toast.makeText(this, "Please Enter Emailsss", Toast.LENGTH_SHORT).show();
return;
}
if(TextUtils.isEmpty(password)){
Toast.makeText(this, "Please Enter Your PASSWORDS", Toast.LENGTH_SHORT).show();
return;
}
progressDialog.setMessage("Login....");
progressDialog.show();
firebaseAuth.signInWithEmailAndPassword(email,password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
progressDialog.dismiss();
if(task.isSuccessful()){
onAuthSuccess(task.getResult().getUser());
//Toast.makeText(signinActivity.this, "Successfully Signed In", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(signinActivity.this, "Could not login, password or email wrong , bullcraps", Toast.LENGTH_SHORT).show();
}
}
});
}
private void onAuthSuccess(FirebaseUser user) {
//String username = usernameFromEmail(user.getEmail())
if (user != null) {
//Toast.makeText(signinActivity.this, user.getUid(), Toast.LENGTH_SHORT).show();
ref = FirebaseDatabase.getInstance().getReference().child("users").child(user.getUid()).child("type");
ref.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
String value = dataSnapshot.getValue(String.class);
//for(DataSnapshot snapshot : dataSnapshot.getChildren()){
// Toast.makeText(signinActivity.this, value, Toast.LENGTH_SHORT).show();
if(Integer.parseInt(value) == 1) {
//String jason = (String) snapshot.getValue();
//Toast.makeText(signinActivity.this, jason, Toast.LENGTH_SHORT).show();
startActivity(new Intent(signinActivity.this, MainActivity.class));
Toast.makeText(signinActivity.this, "You're Logged in as Seller", Toast.LENGTH_SHORT).show();
finish();
} else {
startActivity(new Intent(signinActivity.this, BuyerActivity.class));
Toast.makeText(signinActivity.this, "You're Logged in as Buyer", Toast.LENGTH_SHORT).show();
finish();
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
}
