Microsoft Translator錯誤：檢索翻譯錯誤

我一直在嘗試創建一個翻譯器應用程序，並且我已經設置了相應的所有內容。但是，我仍然得到這個特定的錯誤，並試圖解決它一段時間。Microsoft Translator錯誤：檢索翻譯錯誤

應用程序不會崩潰，但會給出錯誤。我究竟做錯了什麼？

這條線在日誌中是最重要的一條：

Caused by: android.os.NetworkOnMainThreadException

所以每次使用函數調用Translate.execute時間，創建一個新的主題：

new Thread(){ 
    public void run() { 

     // ... 
     translate(...); 
     // ... 

    } 
}.start();

這不是一個完整的解決方案，因爲你忽略了'translate'方法的返回值。如果你得到它，你應該更新UI，這不能從後臺線程完成，但可以使用'runOnUiThread'來實現。 – nikis 2015-04-03 10:10:59

是的，你的答案更完整。我的回答只是爲了提示*指向正確的方向，我不想重寫他的代碼。無論如何，我upvoted你的答案:) – ByteHamster 2015-04-03 11:14:47

這裏的問題是從主線程禁止網絡調用API 11，否則主線程（UI線程）將被阻塞wai爲響應。如果你把你會發現堆棧跟蹤，一看就是當你調用下面一行在你的點擊處理程序：

textViewTranslatedText.setText(translate(textViewReceived.getText().toString(), spinner.getSelectedItem().toString()));

網絡呼叫將由API您使用在以下行來進行：

Translate.execute(text, send);

要避免此異常，您應該以異步方式調用Translate.execute。最簡單的方法是使用AsyncTask如果這個網絡的要求並不需要太多的時間：

private static class MyAsyncTask extends AsyncTask<Request, Void, String>{ 

    private WeakReference<TextView> translatedView; 

    public MyAsyncTask(TextView translatedView) { 
     this.translatedView = new WeakReference<TextView>(translatedView); 
    } 

    @Override 
    protected String doInBackground(Request... params) { 
     Request req = params[0]; 
     String translatedText = Translate.execute(req.getText(), req.getLanguage()); 
     return translatedText; 
    } 

    @Override 
    protected void onPostExecute(String s) { 
     TextView output = translatedView.get(); 
     if (output != null){ 
      output.setText(s); 
     } 
    } 
} 

private static class Request { 
    private String text; 
    private Language language; 

    public Request(Language language, String text) { 
     this.language = language; 
     this.text = text; 
    } 

    public Language getLanguage() { 
     return language; 
    } 

    public void setLanguage(Language language) { 
     this.language = language; 
    } 

    public String getText() { 
     return text; 
    } 

    public void setText(String text) { 
     this.text = text; 
    } 
}

不過，也有關於如何做異步操作，就像使用IntentService另一個方法，創建HandlerThread，等解決方案取決於你的需求和要求。你可以在這裏閱讀一些信息http://blog.nikitaog.me/2014/10/11/android-looper-handler-handlerthread-i/

謝謝大家！ :) – 2015-04-03 10:14:41

仍給出了相同的錯誤！：/ – 2015-04-03 11:02:41

顯示你做了什麼。你以前使用過'AsyncTask'嗎？ – nikis 2015-04-03 11:05:08
