私は次のコードに取り組んでいます：

import android.widget.Toast;
public class BlueInterface extends Service implements TextToSpeech.OnInitListener{
static VoiceStuff carpart;
Context context;
private TextToSpeech tts;
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate(){
super.onCreate();
Log.d("interface","interface onStart called");
carpart = new VoiceStuff(context);
tts = new TextToSpeech(this, this);
PackageManager pm = getPackageManager();
List <ResolveInfo> activities = pm.queryIntentActivities(new Intent (RecognizerIntent.ACTION_RECOGNIZE_SPEECH),0);
if (activities.size()!=0){
Log.d("interface","Speach stuff ready to go");
}
else{
Log.d("interface","Speach stuff not present");
}
}
public static void startListening(Context context){
Log.d("interface","Start Listening called");
carpart.startVoiceRecognitionActivity(context);
}
private class VoiceStuff extends Activity implements TextToSpeech.OnInitListener{
List<ResolveInfo> systemActivities=null;
private VoiceStuff(Context context){
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d("interface","onCreate in voice stuff class called");
}
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;
public void startVoiceRecognitionActivity(Context context){
//super.startVoiceRecognitionActivity(context);
Log.d("Main","method called");
Intent myCrap = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
myCrap.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
myCrap.putExtra(RecognizerIntent.EXTRA_PROMPT,"Speak your command now");
startActivityForResult(myCrap,VOICE_RECOGNITION_REQUEST_CODE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
// Fill the list view with the strings the recognizer thought it could have heard
ArrayList<String> matches = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
String stupid = matches.get(0);
//Toast.makeText(MainRemote.this,"" + stupid, Toast.LENGTH_SHORT).show();
if (stupid.equals("home")) {
//getSpeech(1);
}
if (stupid.equals("map")) {
//getSpeech(2);
}
//mList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,matches));
super.onActivityResult(requestCode, resultCode, data);
}
}
//super.onActivityResult(requestCode, resultCode, context);
public void myStuff(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
// Fill the list view with the strings the recognizer thought it could have heard
ArrayList<String> matches = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
String stupid = matches.get(0);
//Toast.makeText(MainRemote.this,"" + stupid, Toast.LENGTH_SHORT).show();
//mList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,matches));
}
} //closes VoiceStuff
public void speakOut(String speakPlz) {
Log.d("interface","speak has been called");
//String text = txtText.getText().toString();
tts.speak(speakPlz, TextToSpeech.QUEUE_FLUSH, null);
}
public void onInit(int status) {
// TODO Auto-generated method stub
}
}
public void onInit(int status) {
// TODO Auto-generated method stub
}
}
startActivityForResult(i,VOICE_RECOGNITION_REQUEST_CODE);コードをデバッグしようとすると、行が実行されてiいるときVOICE_RECOGNITION_REQUEST_CODEに変数に解決できないことがデバッガーから通知されます。これらの 2 つの変数をいじる内部クラスを使用しているという事実はありますか?
ここで編集はLogCatです：
