E-Mail-Taste in derselben Aktivität OnClickListener mit

Question

Ich versuche, einen Login-Bildschirm für die Nutzer zu bauen, die in der gleichen Aktivität Bildschirm Facebook- und Twitter-Login-Option hat

ich die Facebook-Taste implementiert und Twitter-Button in separaten Aktivitäten, und es hat funktioniert, aber wenn ich die beiden Tasten in der gleichen Aktivität hinzufüge, stürzt es ab.

Dies sind die Fehler:

Das ist mein Quellcode:

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    { 

     setContentView(R.layout.activity_login); 
     info = (TextView) findViewById(R.id.info); 
     FbloginButton = (LoginButton) findViewById(R.id.login_button); 
     TloginButton = (TwitterLoginButton) findViewById(R.id.twitter_login_button); 
     status = (TextView) findViewById(R.id.status); 
     status.setText("Status: Ready"); 


     FbloginButton.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       //initialize facebook sdk 
       FacebookSdk.sdkInitialize(getApplicationContext()); 
       callbackManager = CallbackManager.Factory.create(); 

       FbloginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() { 
        @Override 
        public void onSuccess(LoginResult loginResult) { 
         info.setText(
           "User ID: " 
             + loginResult.getAccessToken().getUserId() 
             + "\n" + 
             "Auth Token: " 
             + loginResult.getAccessToken().getToken() 
         ); 
        } 

        @Override 
        public void onCancel() { 
         info.setText("Login attempt canceled."); 
        } 

        @Override 
        public void onError(FacebookException e) { 
         info.setText("Login attempt failed."); 
        } 
       }); 
      } 
     }); 

     TloginButton.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       //intialize twitter sdk with fabric 
       TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET); 
       Fabric.with(getApplicationContext(), new Twitter(authConfig)); 


       TloginButton.setCallback(new Callback<TwitterSession>() { 
        @Override 
        public void success(Result<TwitterSession> twitterSessionResult) { 
         String output = "Status: " + 
           "Your login was successful " + 
           twitterSessionResult.data.getUserName() + 
           "\nAuth Token Received: " + 
           twitterSessionResult.data.getAuthToken().token; 

         status.setText(output); 
        } 

        @Override 
        public void failure(TwitterException e) { 
         status.setText("Status: Login Failed"); 
        } 
       }); 

      } 
     }); 




@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    callbackManager.onActivityResult(requestCode, resultCode, data); 
    TloginButton.onActivityResult(requestCode, resultCode, data); 

} 

Ich bin verwirrt, ob dies der richtige Weg ist oder nicht.

ist dies die XML-Datei:

  <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:id="@+id/info" 
      android:layout_alignParentLeft="true" 
      android:layout_alignParentTop="true" 
      android:textSize="18sp" 
      /> 

     <com.facebook.login.widget.LoginButton 
      android:id="@+id/login_button" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_centerInParent="true" 
      /> 
     <com.twitter.sdk.android.core.identity.TwitterLoginButton 
      android:id="@+id/twitter_login_button" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_centerInParent="true"/> 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:id="@+id/status" 
      android:layout_alignParentTop="true" 
      android:layout_alignParentLeft="true" 
      android:textSize="20sp" 
      /> 

Answer 1

Facebook SDK, bevor Sie eine ihrer Methoden initialisiert werden muss. Sie können dies tun, indem Sie sdkInitialize aufrufen und den Kontext der Anwendung an ihn übergeben. Fügen Sie den folgenden Code in die onCreate Methode Ihrer Activity vor Onclicklistener:

FacebookSdk.sdkInitialize(getApplicationContext()); 

für twitter auch vor setContentView add:

TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET); 
Fabric.with(this, new Twitter(authConfig));
