Question

我正在尝试使用Google Firebase进行注册，但无法正常工作。在此期间，“对话”框不断加载，即使几分钟后也没有任何反应。
我在AndroidMenifests.xml中添加了互联网连接，并在Firebase控制台上启用了电子邮件/密码身份验证。

我应该怎么做才能使其正常工作？

这是我的MainActivity

 public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    private FirebaseAuth firebaseAuth;
    private EditText editTextEmail;
    private EditText editTextPassword;
    private ProgressDialog progressDialog;

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

        firebaseAuth = FirebaseAuth.getInstance();

        //initializing views
        editTextEmail = (EditText) findViewById(R.id.editTextEmail);
        editTextPassword = (EditText) findViewById(R.id.editTextPassword);

        Button buttonSignup = (Button) findViewById(R.id.buttonSignup);

        progressDialog = new ProgressDialog(this);

        //attaching listener to button
        buttonSignup.setOnClickListener(this);

    }

    private void registerUser(){

        //getting email and password from edit texts
        String email = editTextEmail.getText().toString().trim();
        String password  = editTextPassword.getText().toString().trim();

        //checking if email and passwords are empty
        if(TextUtils.isEmpty(email)){
            Toast.makeText(this,"Please enter email",Toast.LENGTH_LONG).show();
            return;
        }

        if(TextUtils.isEmpty(password)){
            Toast.makeText(this,"Please enter password",Toast.LENGTH_LONG).show();
            return;
        }

        //if the email and password are not empty
        //displaying a progress dialog

        progressDialog.setMessage("Registering Please Wait...");
        progressDialog.show();

        //creating a new user
        firebaseAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        //checking if success
                        if(task.isSuccessful()){
                            //display some message here
                            Toast.makeText(MainActivity.this,"Successfully registered",Toast.LENGTH_LONG).show();
                        }else{
                            //display some message here
                            Toast.makeText(MainActivity.this,"Registration Error",Toast.LENGTH_LONG).show();
                        }
                        progressDialog.dismiss();
                    }
                });

    }

    @Override
    public void onClick(View v) {
        registerUser();

    }
}

在这里，我在 app.gradle 文件
中设置了以下依赖项

    dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.google.firebase:firebase-auth:16.0.3'
    implementation 'com.google.firebase:firebase-database:16.0.2'
    implementation 'com.google.firebase:firebase-storage:16.0.2'
    implementation 'com.google.firebase:firebase-crash:16.2.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-core:16.0.3'
//cloud dep
    implementation 'com.firebase:firebase-client-android:2.3.1'


}
apply plugin: 'com.google.gms.google-services'

和 build.gradle 文件

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:4.0.1'
}

这是AndroidManifests.xml

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.irfan.reg">
    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

That's my Logcat image

Here's how you may want to change your code

你好，我的朋友。我注意到您的onclick方法存在一些问题。我将其删除，并将其放置在标准setOnClickListener中，一切正常。让我知道是否有帮助。

此外，如果您想保留onClick方法，只需删除重写标记并在xml中添加onClick方法即可。

这是您的按钮xml现在的外观。

    <Button
    android:id="@+id/buttonSignup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:text="@string/app_name"
    android:onClick="onClick"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/editTextPassword" />

请注意标签列表中现在的'android：onClick =“ onClick”'标签。希望这对我的朋友有帮助。
