我有一个关于parcelable类（android）的问题。Android：getParcelableArrayList错误（内存不足）
到现在为止，我已经通过了的doubleArray 2意图之间的任何内部消除问题：
new double[] latLong = new double[]{loc.getLatitude(),loc.getLongitude()};
...
intent.putExtra(Site.LATTITUDE, latLong);
...
startActivityForResult(intent, this.ACCESS_GOOGLE);
今天，我试图使用parcelable类相同的活动添加新数据。 我parcelable类：
package common;
import android.os.Parcel;
import android.os.Parcelable;
public class Site implements Parcelable {
private int id;
private String site_name;
private int category ;
private double latitude;
private double longitude;
/**
*
* @param id
* @param site_name
* @param category
*/
public Site(int id, String site_name, int category,double latitude, double lonngitude){
this.id=id;
this.site_name=site_name;
this.category=category;
this.latitude=latitude;
this.longitude=longitude;
}
public Site(Parcel in){
readFromParcel(in);
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(this.id);
dest.writeString(this.site_name);
dest.writeInt(this.category);
dest.writeDouble(this.latitude);
dest.writeDouble(this.longitude);
}
/**
*
* @param in
*/
private void readFromParcel(Parcel in) {
this.id = in.readInt();
this.site_name = in.readString();
this.category = in.readInt();
this.latitude = in.readInt();
this.longitude = in.readInt();
}
public static final Parcelable.Creator CREATOR =
new Parcelable.Creator() {
public SiteGoogle createFromParcel(Parcel in) {
return new Site(in);
}
public SiteGoogle[] newArray(int size) {
return new Site[size];
}
};
/* GETTER/SETTER */
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getSite_name() {
return site_name;
}
public void setSite_name(String site_name) {
this.site_name = site_name;
}
public int getCategory() {
return category;
}
public void setCategory(int category) {
this.category = category;
}
public double getLatitude() {
return latitude;
}
public void setLatitude(double latitude) {
this.latitude = latitude;
}
public double getLongitude() {
return longitude;
}
public void setLongitude(double longitude) {
this.longitude = longitude;
}
}
我把一些站点对象（上面的类）在Java的ArrayList，而这个列表传递给我的第二个活动与下面的代码：
ArrayList<Site> sitesForMap = new ArrayList<Site>();
for(int i=0; i<sites.size();i++){
SiteGoogle site = new SiteGoogle(
sites.get(i).getId(),
sites.get(i).getSite_name(),
sites.get(i).getCat(),
sites.get(i).getLatitude(),
sites.get(i).getLongitude());
sitesForGoogle.add(site);
}
//put data in the intent
intent.putExtra(Site.LATTITUDE, latLong); //first data that worked well until now
intent.putParcelableArrayListExtra(Site.JSON_ARRAY, sitesForMap); //my new data
startActivityForResult(intent, this.ACCESS_GOOGLE);
执行该代码完美（sitesForMap和latLong不为null），但在第二个Activity中，当我尝试实例化第一个Double []参数时，发生错误。
Bundle bundle = getIntent().getExtras();
double[] adresse = (double[]) bundle.getDoubleArray(Site.LATTITUDE); //worked well until today
List<Site> sitesList = bundle.getParcelableArrayList(Site.JSON_ARRAY);
错误：

有人知道这是什么问题？
谢谢你阅读我的留言！
你救了我一命Yuku！谢谢你们的快速响应。我将“readint”更改为“readDouble”，现在它运行良好。 – johann
感谢yuku指出这个地方，在我的情况下，我忘了添加行writeToParcel（）... – MartinC
