Question

我试图在单击按钮时打开下一页，同时存储已输入的值。但是每次我单击按钮时，我都会从else语句中得到消息。我哪里出问题了？

这是我的课程代码：

package com.example.wirespeed_systems.k_mart;

import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.design.widget.TextInputEditText;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.AuthResult;
import com.google.firebase.auth.FirebaseAuth;

public class RegisterActivity extends AppCompatActivity {
    private TextInputEditText mDisplayName;
    private TextInputEditText mEmail;
    private TextInputEditText mPassword;
    private Button mCreateBtn;
    private FirebaseAuth mAuth;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);

        mAuth = FirebaseAuth.getInstance();

        mDisplayName = (TextInputEditText)findViewById(R.id.reg_disName);
        mEmail = (TextInputEditText)findViewById(R.id.reg_email);
        mPassword = (TextInputEditText)findViewById(R.id.reg_password);
        mCreateBtn = (Button)findViewById(R.id.reg_create);

        mCreateBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String display_name = mDisplayName.getText().toString();
                String email = mEmail.getText().toString();
                String password = mPassword.getText().toString();

               registerUser(display_name,email,password);
            }
        });
    }

    private void registerUser(String display_name, String email, String password) {
        mAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            Intent mainIntent = new Intent(RegisterActivity.this, MainActivity.class);
                            startActivity(mainIntent);
                            finish();
                        } else {
                            Toast.makeText(RegisterActivity.this, "Authentication failed.",
                                    Toast.LENGTH_SHORT).show();
                        }
                    }
                });
    }
}

这是我的活动课程代码：

运行此代码时，它应该存储信息并打开MainActivity。

Answer 1

可能有4种可能性：

第一个：

将此添加到依赖项中，

implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-auth:16.0.3'

第二个：

更改：

mAuth.createUserWithEmailAndPassword(email, password)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                ......

收件人：

mAuth.createUserWithEmailAndPassword(email, password)
            .addOnCompleteListener(RegisterActivity.this, new OnCompleteListener<AuthResult>() {
                @Override
                ......

第三名：

尝试提供一个强密码，例如“ JohnDoe @ 12345”，因为您必须满足Google的密码复杂性标准。

第四名：

检查是否已添加Internet权限：

<uses-permission ....... INTERNET>

在您的清单中。

希望有些事情能奏效。尝试让我知道..：）

单击按钮后无法继续进行下一个活动
