我正在DetectedActivity上工作，目前在此方面取得了成功的结果。现在我想获取我的应用程序被杀死时用户检测到的活动（日志或吐司）。我已经阅读了ActivityRecognization和"IntentService"的api的Google文档。因此，即使我的应用程序被杀死，我也不知道如何在烤面包中获取detectedActivity的“信心”值。有人可以帮我吗？我的代码如下。
ActivityIntentService
"PendingIntent"我在活动班级中使用此public class ActivityIntentService extends IntentService {
protected static final String TAG = "Activity";
static int confidence;
static int activityType;
static String test;
//Call the super IntentService constructor with the name for the worker thread//
public ActivityIntentService() {
super(TAG);
}
@Override
public void onCreate() {
super.onCreate();
}
//Define an onHandleIntent() method, which will be called whenever an activity detection update is available//
@Override
protected void onHandleIntent(Intent intent) {
//Check whether the Intent contains activity recognition data//
if (ActivityRecognitionResult.hasResult(intent)) {
//If data is available, then extract the ActivityRecognitionResult from the Intent//
ActivityRecognitionResult result = ActivityRecognitionResult.extractResult(intent);
//Get an array of DetectedActivity objects//
ArrayList<DetectedActivity> detectedActivities = (ArrayList) result.getProbableActivities();
PreferenceManager.getDefaultSharedPreferences(this)
.edit()
.putString(MainActivity.DETECTED_ACTIVITY,
detectedActivitiesToJson(detectedActivities))
.apply();
DetectedActivity mostProbableActivity;
mostProbableActivity = result.getMostProbableActivity();
confidence = mostProbableActivity.getConfidence();
activityType = mostProbableActivity.getType();
Toast.makeText(this,"DETECTION IS RUNNING",Toast.LENGTH_LONG).show();
if (mostProbableActivity.equals("STILL") &&confidence > 80)
{
Toast.makeText(this,"STILL",Toast.LENGTH_LONG).show();
}
}
}
//Convert the code for the detected activity type, into the corresponding string//
@SuppressLint("StringFormatInvalid")
static String getActivityString(Context context, int detectedActivityType) {
Resources resources = context.getResources();
switch(detectedActivityType) {
case DetectedActivity.ON_BICYCLE:
return resources.getString(R.string.bicycle);
case DetectedActivity.ON_FOOT:
return resources.getString(R.string.foot);
case DetectedActivity.RUNNING:
return resources.getString(R.string.running);
case DetectedActivity.STILL:
return resources.getString(R.string.still);
case DetectedActivity.TILTING:
return resources.getString(R.string.tilting);
case DetectedActivity.WALKING:
return resources.getString(R.string.walking);
case DetectedActivity.IN_VEHICLE:
return resources.getString(R.string.vehicle);
default:
return resources.getString(R.string.unknown_activity, detectedActivityType);
}
}
static final int[] POSSIBLE_ACTIVITIES = {
DetectedActivity.STILL,
DetectedActivity.ON_FOOT,
DetectedActivity.WALKING,
DetectedActivity.RUNNING,
DetectedActivity.IN_VEHICLE,
DetectedActivity.ON_BICYCLE,
DetectedActivity.TILTING,
DetectedActivity.UNKNOWN
};
static String detectedActivitiesToJson(ArrayList<DetectedActivity> detectedActivitiesList) {
Type type = new TypeToken<ArrayList<DetectedActivity>>() {}.getType();
return new Gson().toJson(detectedActivitiesList, type);
}
static ArrayList<DetectedActivity> detectedActivitiesFromJson(String jsonArray) {
Type listType = new TypeToken<ArrayList<DetectedActivity>>(){}.getType();
ArrayList<DetectedActivity> detectedActivities = new Gson().fromJson(jsonArray, listType);
if (detectedActivities == null) {
detectedActivities = new ArrayList<>();
}
return detectedActivities;
}
}
，如下所示：
service请有人帮我。预先谢谢你
