我使用下面显示的简单电子邮件密码进行注册活动以在Firebase上创建新用户
公共类CreateAccountActivity扩展了AppCompatActivity {
private ProgressDialog mprogress;
private RelativeLayout signUpactivity;
FirebaseUser user;
private Button msignUp;
public EditText mName,mEmail,mPassword,mCon_Password,mschl_name;
Spinner gender;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_creat_acc);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
mAuth = FirebaseAuth.getInstance();
mprogress = new ProgressDialog(this);
msignUp = (Button) findViewById(R.id.signUp);
signUpactivity = (RelativeLayout) findViewById(R.id.activity_signUp);
mName = (EditText) findViewById(R.id.namefield);
mEmail = (EditText) findViewById(R.id.emailField);
mPassword = (EditText) findViewById(R.id.passwordField);
mschl_name = (EditText) findViewById(R.id.sname);
String[] option = new String[]{
"Male", "Female"
};
gender = (Spinner) findViewById(R.id.gender);
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, option);
arrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
gender.setAdapter(arrayAdapter);
msignUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(isNetworkAvailable()){
mprogress.setMessage("Creating Account...");
mprogress.show();
mprogress.setCanceledOnTouchOutside(false);
mprogress.setCancelable(false);
createAccount();
}else{
Snackbar.make(signUpactivity, "Network UnAvailable", Snackbar.LENGTH_SHORT).show();
}
}
});
}
private boolean isNetworkAvailable() {
ConnectivityManager manager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = manager.getActiveNetworkInfo();
return networkInfo != null && networkInfo.isConnected();
}
View focusview = null;
boolean cancel = false;
private void createAccount(){
final String name = mName.getText().toString();
String email = mEmail.getText().toString();
String password = mPassword.getText().toString();
final String gendertxt = gender.getSelectedItem().toString();
final String schl_name = mschl_name.getText().toString();
String edu_email = email+"@edutree.com";
if (isNetworkAvailable()){
mAuth.createUserWithEmailAndPassword(edu_email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(Task<AuthResult> task) {
if(task.isSuccessful()){
user = FirebaseAuth.getInstance().getCurrentUser();
String user_email = user.getEmail();
String gendertxt = gender.getSelectedItem().toString();
UserProfileChangeRequest profileChangeRequest = new UserProfileChangeRequest.Builder().setDisplayName(name).build();
user.updateProfile(profileChangeRequest).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(Task<Void> task) {
if(task.isSuccessful()){
Log.d("Profile", "User Profile Updated successfully");
FirebaseCrash.log("Profile Updated");
}else {
Log.d("Error","error while updating profile");
FirebaseCrash.log("Error while updating profile");
}
}
});
mprogress.dismiss();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent intent = new Intent(CreateAccountActivity.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
Toast.makeText(CreateAccountActivity.this, "Welcome "+ FirebaseAuth.getInstance().getCurrentUser().getEmail(), Toast.LENGTH_LONG).show();
}
},500);
}else{
Snackbar.make(signUpactivity, "Error occurred" , Snackbar.LENGTH_SHORT).show();
mprogress.dismiss();
}
}
});
}else {
Snackbar.make(signUpactivity, "Network UnAvailable", Snackbar.LENGTH_SHORT).show();
mprogress.dismiss();
}
}
}
当用户输入信息时，它启动方法CreateAccount（），然后当任务成功时，它更新用户配置文件并设置显示名称并启动MainActivity。但它启动MainActivty它没有显示用户名。
任何人都可以帮我修复此问题，当用户退出并重新登录时，它会显示该名称，否则在注册后无法显示。
非常感谢任何答案

您需要将启动MainActivity的代码移动到onComplete（）方法内以进行配置文件更改。现在，您的代码启动Firebase用户配置文件更改以存储显示名称，但在完成用户配置文件更改之前显示MainActivity。
您可以更新这部分代码，查看我在onComplete（）方法末尾添加的内容：
user.updateProfile(profileChangeRequest).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(Task<Void> task) {
if(task.isSuccessful()){
Log.d("Profile", "User Profile Updated successfully");
FirebaseCrash.log("Profile Updated");
}else {
Log.d("Error","error while updating profile");
FirebaseCrash.log("Error while updating profile");
}
mprogress.dismiss();
Intent intent = new Intent(CreateAccountActivity.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
Toast.makeText(CreateAccountActivity.this, "Welcome "+ FirebaseAuth.getInstance().getCurrentUser().getEmail(), Toast.LENGTH_LONG).show();
}
});
然后，您可以稍后在函数中删除此代码：
mprogress.dismiss();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent intent = new Intent(CreateAccountActivity.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
Toast.makeText(CreateAccountActivity.this, "Welcome "+ FirebaseAuth.getInstance().getCurrentUser().getEmail(), Toast.LENGTH_LONG).show();
}
},500);
