我有一个小部件,它会在点击时打开默认的语音识别器活动。现在我希望来自此活动的数据进入我的服务,该服务进行一些处理。我可以使用以下代码启动语音识别器活动
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
ComponentName thisWidget = new ComponentName(context,
MicWidgetProvider.class);
int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
for (int widgetId : allWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.mic_widget_layout);
// this intent points to activity that should handle results
Intent serviceIntent = new Intent(context,
SpeechWidgetService.class);
// this intent wraps results activity intent
PendingIntent resultsPendingIntent = PendingIntent.getService(
context, REQUEST_CODE, serviceIntent, 0);
// this intent calls the speech recognition
Intent voiceIntent = new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
voiceIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Jarvis");
voiceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT,
resultsPendingIntent);
// this intent wraps voice recognition intent
PendingIntent pendingIntent = PendingIntent.getActivity(context,
REQUEST_CODE, voiceIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.arc_widget, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
Log.d(TAG, "clicking..");
}
当我单击小部件时,一切正常,我可以说话,当我停止说话时它会关闭。问题是根本没有调用该服务。我究竟做错了什么?现在我只有一个虚拟服务来检查数据是否进入。
public class SpeechWidgetService extends Service {
private static final String TAG = "SpeechWidgetService";
@Override
public IBinder onBind(Intent intent) {
ArrayList<String> voiceResults = intent.getExtras().getStringArrayList(RecognizerIntent.EXTRA_RESULTS);
Log.d(TAG, voiceResults.get(0));
Toast.makeText(getBaseContext(), voiceResults.get(0), Toast.LENGTH_SHORT).show();
return null;
}
@Override
public void onCreate() {
Log.d(TAG, "onCreate");
super.onCreate();
}
@Override
public void onStart(Intent intent, int startId) {
Log.d(TAG, "onStart");
}
}
