android - android Activity Recognition Parcelable 协议需要 Parcelable.Creator

Question

我遇到活动识别问题，并且收到以下错误：

05-07 22:32:03.553: E/AndroidRuntime(5546): FATAL EXCEPTION: IntentService[dk.finne.minrute.service.ActivityRecognitionIntentService]
05-07 22:32:03.553: E/AndroidRuntime(5546): Process: dk.finne.minrute, PID: 5546
05-07 22:32:03.553: E/AndroidRuntime(5546): android.os.BadParcelableException: Parcelable protocol requires a Parcelable.Creator object called  CREATOR on class com.google.android.gms.location.ActivityRecognitionResult
05-07 22:32:03.553: E/AndroidRuntime(5546):     at android.os.Parcel.readParcelableCreator(Parcel.java:2156)

该ActivityRecognitionResult课程来自 Google Play 服务，那么我该如何解决此错误？

这是一个工作示例，除了传递活动（仍然没有弄清楚）。基本上你没有创造者的东西。下次如果您包含代码示例，它会有所帮助。

import android.app.Activity;

import android.os.Parcel;
import android.os.Parcelable;

public class QueryParcible implements Parcelable{
private long fromBtn,toBtn;
private Boolean gpsB, picB;
Activity activity;

public QueryParcible() {}
public QueryParcible(Parcel parcel) {}

    public static final Parcelable.Creator<QueryParcible> CREATOR =
               new Parcelable.Creator<QueryParcible>(){

                @Override
      public QueryParcible createFromParcel(Parcel source)     {
                 return new QueryParcible(source);
                }

                @Override
                public QueryParcible[] newArray(int size) {
                 return new QueryParcible[size];
                }
             };
             @Override
             public int describeContents() {
              return 0;
             }

             @Override
             public void writeToParcel(Parcel dest, int flags) {
                 dest.writeSerializable(fromBtn);
                 dest.writeSerializable(toBtn);              
                 dest.writeInt(gpsB?1:0);
                 dest.writeInt(picB?1:0);   
                 dest.writeValue(activity);
             }  
            public void readFromParcel(Parcel source){
                 fromBtn= source.readLong();
                 toBtn= source.readLong();               
                 gpsB=source.readInt()==1;
                 picB=source.readInt()==1;
                // activity=source.readValue(activity);
             }

             public Boolean getGpsB() {
                return gpsB;
            }
            public void setGpsB(Boolean gpsB) {
                this.gpsB = gpsB;
            }
            public Boolean getPicB() {
                return picB;
            }
            public void setPicB(Boolean picB) {
                this.picB = picB;
                }
public long getFromBtn() {
    return fromBtn;
}
public void setFromBtn(long fromBtn) {
    this.fromBtn = fromBtn;
}
public long getToBtn() {
    return toBtn;
}
public void setToBtn(long toBtn) {
    this.toBtn = toBtn;
}   
public Activity getActivity() {
return activity;
}
public void setActivity(Activity activity) {
this.activity = activity;
}       }
