【问题描述】：
这是我的登录活动，当我单击登录按钮时，它不会启动 MainActivity，但是当我关闭并重新打开应用程序时它可以工作，为什么请帮忙
公共类 Auth1Activity 扩展 AppCompatActivity {
String string_1;
String string_2;
private static final Boolean CHECK_EMAIL_VERIFIED = false;
private static final String TAG = "LoginActivity";
private FirebaseAuth firebaseAuth;
private FirebaseAuth.AuthStateListener authStateListener;
private FirebaseUser firebaseUser;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_auth_1);
firebaseAuth = FirebaseAuth.getInstance();
authStateListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
}
};
firebaseUser = firebaseAuth.getCurrentUser();
if (firebaseUser != null) {
Intent intent = new Intent(Auth1Activity.this, MainActivity.class);
startActivity(intent);
finish();
}
final EditText auth_layout_1_edit_text_1 = findViewById(R.id.auth_layout_1_edit_text_1);
final EditText auth_layout_1_edit_text_2 = findViewById(R.id.auth_layout_1_edit_text_2);
Button auth_layout_1_button = findViewById(R.id.auth_layout_1_button);
auth_layout_1_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
string_1 = auth_layout_1_edit_text_1.getText().toString();
string_2 = auth_layout_1_edit_text_2.getText().toString();
if (string_1.matches("") && string_2.matches("")) {
auth_layout_1_edit_text_1.setError("Enter Email Address");
auth_layout_1_edit_text_2.setError("Enter Password");
} else if (!string_1.matches("") && !string_2.matches("")) {
firebaseAuth.signInWithEmailAndPassword(string_1, string_2).addOnCompleteListener(Auth1Activity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
try {
if (firebaseUser.isEmailVerified()) {
Intent intent = new Intent(Auth1Activity.this, MainActivity.class);
startActivity(intent);
finish();
} else if (!firebaseUser.isEmailVerified()) {
Toast.makeText(Auth1Activity.this, "Sign Up Error Please Try Again.", Toast.LENGTH_SHORT).show();
}
} catch (NullPointerException ignored) {
}
}
});
}
}
});
}
@Override
public void onStart() {
super.onStart();
firebaseAuth.addAuthStateListener(authStateListener);
}
@Override
public void onStop() {
super.onStop();
if (authStateListener != null) {
firebaseAuth.removeAuthStateListener(authStateListener);
}
}
}
