RESULT_OK上的錯誤public void onActivityResult

-3

我在我的MainActivity上有這段代碼，但是當我在HomeFragment的片段上嘗試它時，我在Public void onActivityResult的RESULT_OK處得到了一個錯誤。RESULT_OK上的錯誤public void onActivityResult

我不知道這是怎麼回事，有沒有人知道這件事？反正here`s我的代碼：

RESULT_OK是恆定的Activity類的，你不能在片段得到它的照片直接。使用下列內容：

if(result_code == Activity.RESULT_OK)

既然你是一個Fragment你必須調用Activity.RESULT_OK或者你也可以使用getActivity().RESULT_OK如下：

if(result_code == Activity.RESULT_OK){ 
    //stuff 
}

但不要忘記調用getActivity().startActivityForResult(intent);當你等待結果，例如您的Intent應該看起來像：

public void promptSpeechInput(){ 

Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault()); 
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say Something!"); 

try{ 

    getActivity().startActivityForResult(i, 100); //Here<---- Add getActivity(). 
    resultTEXT.setText(""); 
    resultTEXT2.setText(""); 
} 
catch(ActivityNotFoundException a){ 
    //Toast.makeText.(MainActivity.this, "Sorry your device does not support speech language! ", Toast.LENGTH_LONG).show(); 
} 
}

順便說拿這個來看看：

/** Standard activity result: operation canceled. */ 
public static final int RESULT_CANCELED = 0; 
/** Standard activity result: operation succeeded. */ 
public static final int RESULT_OK   = -1; 
/** Start of user-defined activity results. */ 
public static final int RESULT_FIRST_USER = 1;

既然你傳遞一個100你想要得到的是100了，所以也許這是另外一個問題，我不knowif。
