我目前有登录/注册设置，用户必须先登记才能登录。在我的register.xml我有4个EditText＆＃39; s rusername，{{ 1}}，remail，rpassword）和提交按钮rconfirmPassword。

registerb

这是java：

问题：

当用户输入虚假电子邮件时，Firebase会显示，只有当我输入电子邮件时，例如public class Register extends AppCompatActivity { EditText musername; EditText memail; EditText mpassword; EditText mconfirmpass; Button mregister; private FirebaseAuth mAuth; private ProgressDialog mProgress; private DatabaseReference mDatabse; int minL; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_register); musername = (EditText) findViewById(R.id.rusername); memail = (EditText) findViewById(R.id.remail); mpassword = (EditText) findViewById(R.id.rpassword); mconfirmpass = (EditText) findViewById(R.id.rpasswordconfirm); mregister = (Button) findViewById(R.id.registerb); minL = 5; mDatabse = FirebaseDatabase.getInstance().getReference().child("Users"); mProgress = new ProgressDialog(this); mAuth = FirebaseAuth.getInstance(); mregister.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { startRegister(); } }); } private void startRegister() { String character = "@"; final String name = musername.getText().toString().trim(); String mail = memail.getText().toString().trim(); String pass = mpassword.getText().toString().trim(); String passconf = mconfirmpass.getText().toString().trim(); if (!TextUtils.isEmpty(name) && !TextUtils.isEmpty(mail) && !TextUtils.isEmpty(pass) && !TextUtils.isEmpty(passconf) && pass.equals(passconf) && pass.length() > 5) { mProgress.setMessage("Signing up..."); mProgress.show(); mAuth.createUserWithEmailAndPassword(mail, pass).addOnCompleteListener(new OnCompleteListener<AuthResult>() { @Override public void onComplete(@NonNull Task<AuthResult> task) { if (task.isSuccessful()) { String user_id = mAuth.getCurrentUser().getUid(); DatabaseReference current_user_db = mDatabse.child(user_id); current_user_db.child("username").setValue(name); current_user_db.child("image").setValue("default"); mProgress.dismiss(); Intent intent = new Intent(Register.this, Home.class); // Clear other activities intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY); startActivity(intent); finish(); } } }); }else { if (!TextUtils.isEmpty(name) && !TextUtils.isEmpty(mail) && !TextUtils.isEmpty(pass) && !TextUtils.isEmpty(passconf) && pass.equals(passconf) && pass.length() < 6){ Toast.makeText(Register.this, "Password should be 6 or more", Toast.LENGTH_SHORT).show(); } if (TextUtils.isEmpty(name) && !TextUtils.isEmpty(mail) && !TextUtils.isEmpty(pass) && !TextUtils.isEmpty(passconf)){ Toast.makeText(Register.this, "Please enter Username", Toast.LENGTH_SHORT).show(); }if (TextUtils.isEmpty(name) && TextUtils.isEmpty(mail) && TextUtils.isEmpty(pass) && TextUtils.isEmpty(passconf)){ Toast.makeText(Register.this, "Please enter your information", Toast.LENGTH_SHORT).show(); }if (!TextUtils.isEmpty(name) && TextUtils.isEmpty(mail) && TextUtils.isEmpty(pass) && TextUtils.isEmpty(passconf)){ Toast.makeText(Register.this, "Please enter your email", Toast.LENGTH_SHORT).show(); }if (!TextUtils.isEmpty(name) && !TextUtils.isEmpty(mail) && TextUtils.isEmpty(pass) && TextUtils.isEmpty(passconf)){ Toast.makeText(Register.this, "Please enter your password", Toast.LENGTH_SHORT).show(); }if (!TextUtils.isEmpty(name) && !TextUtils.isEmpty(mail) && !TextUtils.isEmpty(pass) && TextUtils.isEmpty(passconf)){ Toast.makeText(Register.this, "Please confirm your password", Toast.LENGTH_SHORT).show(); }if (!TextUtils.isEmpty(name) && TextUtils.isEmpty(mail) && !TextUtils.isEmpty(pass) && !TextUtils.isEmpty(passconf)){ Toast.makeText(Register.this, "Please enter Email", Toast.LENGTH_SHORT).show(); }if (!TextUtils.isEmpty(name) && !TextUtils.isEmpty(mail) && TextUtils.isEmpty(pass) && !TextUtils.isEmpty(passconf)){ Toast.makeText(Register.this, "Please enter Password", Toast.LENGTH_SHORT).show(); } if (!pass.equals(passconf)){ Toast.makeText(Register.this, "Please check password combination", Toast.LENGTH_SHORT).show(); } }} }才会注册成功。如果电子邮件不正确，我的###@###.com将继续加载。

问题：

如何在几秒钟后解除progressDialog并显示progressDialog，告诉用户输入有效的电子邮件？

我只是检查你检查的代码

if (task.isSuccessful()) {
//your code
}
else{
mProgress.dismiss();
}

试试这个。
