我的LoginActivity包含EditText，供用户输入其电子邮件和密码。在我看来，所有代码都可以。
但是，单击登录按钮后，用户不会登录。事实证明，该电子邮件无效，其中EditText电子邮件包含以下内容：
android.support.v7.widget.AppCompatEditText{b014ce3 VFED..CL. .F...... 56,646-1384,804 #7f0d0096 app:id/etEmailLogin}
请帮助我找出问题所在。

这两个Toast的显示内容相同：

另外，请让我知道为什么会这样：

最佳答案
首先，请确保在Firebase控制台中一切看起来都不错（有帐户等）。
现在似乎没有任何代码可以处理登录失败的情况。我刚刚在我的应用中使用Firebase实施了登录，因此这是用户按下登录按钮时使用的代码。 （注意：我刚刚注意到一个错误，该错误在于在return语句之前按钮没有再次设置为可单击，但除此之外一切都很好）
// authenticates user, and starts main activity if successful
@OnClick(R.id.login_button)
public void login(View view) {
// prevents the user launching the main activity multiple times if their login is valid
loginButton.setClickable(false);
String email = null;
String pass = null;
// prevents null entries for email
if (usernameInput.getText().length() != 0) {
email = usernameInput.getText().toString();
} else {
Toast.makeText(LoginScreen.this, "Please enter your email",
Toast.LENGTH_SHORT).show();
return;
}
// prevents null entries for pass
if (passwordInput.getText().length() != 0) {
pass = passwordInput.getText().toString();
} else {
Toast.makeText(LoginScreen.this, "Please enter your password",
Toast.LENGTH_SHORT).show();
return;
}
// signs in with the entered email and pass
AuthManager.firebaseAuth.signInWithEmailAndPassword(email,pass)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
// sign in success
Log.v(TAG, "signIn:onComplete:" + task.isSuccessful());
// if sign in is successful, pass auth info to global variables, and launch intent and start the main activity
if (task.isSuccessful()){
AuthManager.user = AuthManager.firebaseAuth.getCurrentUser();
AuthManager.userUID = AuthManager.user.getUid();
AuthManager.loggedIn = true;
// creates the DB manager to make initial and future DB calls
new DBManager();
Toast.makeText(LoginScreen.this, "Signed in",
Toast.LENGTH_SHORT).show();
startMainActivity();
} else {
// if sign in fails
Log.w(TAG, "signIn", task.getException());
Toast.makeText(LoginScreen.this, "Incorrect username or password",
Toast.LENGTH_SHORT).show();
// makes the button clickable again
loginButton.setClickable(true);
}
}
});
}
我还在实现中使用了自定义AuthManager类，但是设置FirebaseAuth对象的方式非常适合它工作。
