Twitter Android登錄錯誤使用twitter4j庫

我想使用Twitter4j庫登錄到我的Twitter應用程序。但是每當我點擊登錄按鈕時，我的應用程序就會崩潰。Twitter Android登錄錯誤使用twitter4j庫

這是我從我的類方法 -

btnLoginTwitter.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // Call login twitter function 
      loginToTwitter(); 
     } 
    }); 


/** 
* Function to login twitter 
* */ 
private void loginToTwitter() { 
    // Check if already logged in 
    if (!isTwitterLoggedInAlready()) { 
     ConfigurationBuilder builder = new ConfigurationBuilder(); 
     builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY); 
     builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET); 
     Configuration configuration = builder.build(); 

     TwitterFactory factory = new TwitterFactory(configuration); 
     twitter = factory.getInstance(); 

     try { 
      requestToken = twitter 
        .getOAuthRequestToken(TWITTER_CALLBACK_URL); 
      this.startActivity(new Intent(Intent.ACTION_VIEW, Uri 
        .parse(requestToken.getAuthenticationURL()))); 
     } catch (TwitterException e) { 
      e.printStackTrace(); 
     } 
    } else { 
     // user already logged into twitter 
     Toast.makeText(getApplicationContext(), 
       "Already Logged into twitter", Toast.LENGTH_LONG).show(); 
    } 
}

當我按下按鈕登錄它顯示了以下的logcat -

「android.os.NetworkOnMainThreadException」意味着你正在執行網絡相關功能像Http的帖子，得到等等在你的主GUI線程..你所要做的就是把這東西放在AsyncTask

做這樣的事情：

private void loginToTwitter() 
{ 
new AsyncTask<Void, Void, Boolean>() { 
@Override 
protected void onPreExecute() { 
       super.onPreExecute(); 
} 

@Override 
protected Boolean doInBackground(Void... params) { 
if (!isTwitterLoggedInAlready()) { 
ConfigurationBuilder builder = new ConfigurationBuilder(); 
builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY); 
builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET); 
Configuration configuration = builder.build(); 

TwitterFactory factory = new TwitterFactory(configuration); 
twitter = factory.getInstance(); 

try { 
requestToken = twitter 
      .getOAuthRequestToken(TWITTER_CALLBACK_URL); 
return true; 
} catch (TwitterException e) { 
e.printStackTrace(); 
} 
} else { 
return false; 
} 
} 

@Override 
protected void onPostExecute(Boolean result) { 
super.onPostExecute(result); 

if(result) 
{ 
this.startActivity(new Intent(Intent.ACTION_VIEW, Uri 
        .parse(requestToken.getAuthenticationURL()))); 
}else{ 
Toast.makeText(getApplicationContext(), 
       "Already Logged into twitter", Toast.LENGTH_LONG).show();} 
} 
}.execute(); 
}

注意：你不能從doInBackgroung()訪問GUI線程你可以從preExecute和postExecute方法

應我把整個登錄方法的AsyncTask：

嘗試通過如下實施AsyncTask把你的代碼doInBackground()方法？ – user3851588

@ user3851588，是的。 –

無法訪問this.startactivity方法！ :( – user3851588

您正在執行耗時的應用程序的主線程任務訪問GUI線程。這就是爲什麼它給android.os.NetworkOnMainThreadException錯誤。

private class WSCalling extends AsyncTask<Void, Void, Integer> { 
    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
    } 

    @Override 
    protected Integer doInBackground(Void... params) { 
     if (!isTwitterLoggedInAlready()) { 
    ConfigurationBuilder builder = new ConfigurationBuilder(); 
    builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY); 
    builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET); 
    Configuration configuration = builder.build(); 

    TwitterFactory factory = new TwitterFactory(configuration); 
    twitter = factory.getInstance(); 

    try { 
     requestToken = twitter 
       .getOAuthRequestToken(TWITTER_CALLBACK_URL); 

    } catch (TwitterException e) { 
     e.printStackTrace(); 
     } 
    } 
     return requestToken; 
    } 

    @Override 
    protected void onPostExecute(Integer args) { 
      if(args != null) 
     { 
     this.startActivity(new Intent(Intent.ACTION_VIEW, Uri 
       .parse(args.getAuthenticationURL()))); 
     }else { 
    // user already logged into twitter 
    Toast.makeText(getApplicationContext(), 
      "Already Logged into twitter", Toast.LENGTH_LONG).show(); 
    } 
    } 
}
