我在MainActivity上有这个代码,但是当我在我的HomeFragment片段中尝试它时,我在Public void onActivityResult的RESULT_OK上遇到了错误。
我不知道这有什么不对,有人知道吗? 无论如何这里是我的代码:

try

resultTEXT.setText("");
resultTEXT2.setText("");

String what = what1[r.nextInt(4)];
if(toSpeak.equals("how are you") || toSpeak.equals("hi Ashley how are you")|| toSpeak.equals("hey Ashley how are you"))
{
t1.speak(wow, TextToSpeech.QUEUE_FLUSH, null);
resultTEXT2.setText(wow);
}
else if(toSpeak.equals("hey Ashley") || toSpeak.equals("hey")|| toSpeak.equals("Hey")|| toSpeak.equals("Ashley"))
{

}

答案 0 :(得分:2)
RESULT_OK
是Activity类的常量,你不能在片段中获得它的直接。使用以下:
if(result_code == Activity.RESULT_OK)
答案 1 :(得分:0)
由于您在[{1}},因此您需要致电Fragment
,或者您也可以使用Activity.RESULT_OK
,如下所示:
getActivity().RESULT_OK
但是在等待结果时忘记拨打if(result_code == Activity.RESULT_OK){
//stuff
}
,例如您的getActivity().startActivityForResult(intent);
应如下:
Intent
顺便看看这个:
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();
}
}
由于您传递 /** 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;
我不知道您是否也希望获得100
,所以也许这是另一个问题。
