我的登录/注册类的代码是:
package com.example.joshpc.bluetoothattendee;
import android.app.ProgressDialog;
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
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 LoginActivity extends AppCompatActivity {
private EditText etEmail;
private EditText etPassword;
private EditText etRegPW;
private FirebaseAuth firebaseAuth;
private Button loginBut;
private Button regBut;
private ProgressDialog message;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
etEmail = (EditText) findViewById(R.id.etEmail);
etPassword = (EditText) findViewById(R.id.etPassword);
etRegPW = (EditText) findViewById(R.id.etRegPW);
firebaseAuth = FirebaseAuth.getInstance();
loginBut = (Button) findViewById(R.id.bLogin);
regBut = (Button) findViewById(R.id.bRegister);
message = new ProgressDialog(this);
regBut.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
userRegister();
}
});
loginBut.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
userLogin();
}
});
}
private void userRegister(){
String email = etEmail.getText().toString().trim();
String password = etPassword.getText().toString().trim();
String verify = etRegPW.getText().toString().trim();
if(TextUtils.isEmpty(email)){
Toast.makeText(this, "Please enter email", Toast.LENGTH_SHORT).show();
return;
}
if(TextUtils.isEmpty(password)){
Toast.makeText(this, "Please enter password", Toast.LENGTH_SHORT).show();
return;
}
Toast.makeText(this, email, Toast.LENGTH_SHORT).show();
if(TextUtils.equals(password, verify)){
message.setMessage("Registering User...");
message.show();
firebaseAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(task.isSuccessful()){
Toast.makeText(LoginActivity.this, "Successful Registration", Toast.LENGTH_SHORT).show();
message.hide();
sendData();
}
if(!task.isSuccessful()){
Toast.makeText(LoginActivity.this, "Failed Registration", Toast.LENGTH_SHORT).show();
message.hide();
return;
}
}
});
}
else {
Toast.makeText(this, "Passwords do not match", Toast.LENGTH_SHORT).show();
return;
}
}
每当我运行这部分代码时,它最终都会显示“注册失败”的 toast 消息,我不确定为什么。我已经测试了电子邮件、密码的值,并使用 toast 消息进行了验证,以确保它们被正确传递。我也检查了 firebase 建议的代码以对 android 上的用户进行身份验证。
我的 gradle 构建文件是:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
useLibrary 'org.apache.http.legacy'
packagingOptions {
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
exclude 'META-INF/NOTICE.txt'
}
defaultConfig {
applicationId "com.example.joshpc.bluetoothattendee"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled true
debug{debuggable = true}
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.google.android.gms:play-services-gcm:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-database:9.6.1'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'
我也在模拟器上运行它。
如果需要编辑任何内容以便更好地解决问题,请告诉我。
更新:我注册的用户帐户显示在我的 firebase 中,但该应用程序仍在向我发送错误消息。
最佳答案
如果您想知道为什么创建用户失败,您应该显示 Firebase 身份验证给您的原因:
if(!task.isSuccessful()){
FirebaseAuthException e = (FirebaseAuthException )task.getException();
Toast.makeText(LoginActivity.this, "Failed Registration: "+e.getMessage(), Toast.LENGTH_SHORT).show();
message.hide();
return;
}
我强烈建议不要使用 toasts 来显示此类信息,而是(或另外)将其记录下来,以便您在开发时拥有永久记录:
Log.e("LoginActivity", "Failed Registration", e);
