问题描述
我有一个ArrayList与Parcelable数据问题通过使用Android.Bundle两项活动发送
我有两个活动(A和B)。
在Aaaa.class:
的ArrayList<模型与GT; mModelList =新的ArrayList<模型与GT;
//填充的ArrayList与几个模型对象捆绑mBundle =新的捆绑;
意图mIntent =新意图(Aaaa.this,Bbbb.class);mBundle.putParcelableArrayList(模式,mModelList);
mIntent.putExtras(mBundle);startActivity(mIntent);
在Bbbb.class:
捆绑mBundle = getIntent()getExtras()。
ArrayList的<模型与GT; = mBundle.getParcelableArrayList(模式);
该Model.class正在实施Parcelable。
所以,现在的问题是。
当我填写的ArrayList(以Aaaa.class),并把它捆,我可以看到包包含从列表中全面开花的对象。
当我再尝试填写Bbbb.class一个抛出异常的列表。

Line52是
的ArrayList<模型与GT; = mBundle.getParcelableArrayList(模式);
我是绝对不知道哪里出了问题在这里,Model.class工作正常与其他捆绑 - 意图
更新:
模型类为其次。
公共类模型实现Parceleble { 私人字符串名称;
私人字符串的地址; 公共模型(邮包包裹){
}
公共模型(){
}
公共模型(字符串名称,地址字符串){
this.name =名称;
this.address =地址;
} // getter和setter //等于,哈希code,ToString(从理念自动生成) @覆盖
公共无效writeToParcel(包裹包裹,int i)以{
parcel.writeString(名);
parcel.writeString(地址);
} 公共无效readFromParcel(邮包包裹){
this.name = parcel.readString();
this.address = parcel.readString();
} 公共静态Parcelable.Creator<模型与GT; CREATOR =新Parcelable.Creator<模型与GT;(){
@覆盖
众模特createFromParcel(邮包包裹){
返回新模型(包裹);
} @覆盖
众模特[]新的Array(INT大小){
返回新模式[尺寸]
}
};
}
您Parceleble实现看起来不正确的我,的来看看需要什么样的方法/构造需要重写:
......// ==================== Parcelable ====================
公众诠释describeContents(){
返回0;
}公共无效writeToParcel(包裹包裹,诠释标志){
parcel.writeString(名);
parcel.writeString(地址);
}私人模型(包裹中){
名称= in.readString();
地址= in.readString();
}公共静态最终Parcelable.Creator<模型与GT; CREATOR =新Parcelable.Creator<模型与GT;(){
众模特createFromParcel(包裹中){
返回新模型();
} 众模特[] newArray(INT大小){
返回新型号【尺寸】;
}
};......
试试这个code和看看是否有帮助。
I have a Problem with Parcelable Data in an ArrayList sending via two Activities using Android.Bundle
I have two Activities (A and B).
In Aaaa.class:
ArrayList<Model> mModelList = new ArrayList<Model>
//Fill ArrayList with a few Model-Objects
Bundle mBundle = new Bundle;
Intent mIntent = new Intent(Aaaa.this, Bbbb.class);
mBundle.putParcelableArrayList("models", mModelList);
mIntent.putExtras(mBundle);
startActivity(mIntent);
In Bbbb.class:
Bundle mBundle = getIntent().getExtras();
ArrayList<Model> = mBundle.getParcelableArrayList("models");
The Model.class is implementing Parcelable.
So, the Problem is.When I fill the ArrayList (in Aaaa.class) and put it to the Bundle, I can see that the Bundle contains the varios Objects from the List.When I then try to fill the List in Bbbb.class a Exception is Thrown.

Line52 is
ArrayList<Model> = mBundle.getParcelableArrayList("models");
I have absolutly no Idea where is the Problem here, the Model.class is working fine with other Bundle - Intents.
Update:
The Model Class as followed.
public class Model implements Parceleble{
private String name;
private String address;
public Model(Parcel parcel){
}
public Model(){
}
public Model(String name, String address){
this.name = name;
this.address = address;
}
//Getter and Setter
//equals, HashCode, toString (autoGenerated from Idea)
@Override
public void writeToParcel(Parcel parcel, int i){
parcel.writeString(name);
parcel.writeString(address);
}
public void readFromParcel(Parcel parcel){
this.name = parcel.readString();
this.address = parcel.readString();
}
public static Parcelable.Creator<Model> CREATOR = new Parcelable.Creator<Model>(){
@Override
public Model createFromParcel(Parcel parcel){
return new Model(parcel);
}
@Override
public Model[] new Array(int size){
return new Model[size]
}
};
}
Your Parceleble implementation doesn't look quite correct to me, check out the sample code in API to see what are the required method/constructor that need to be overridden:
... ...
// ==================== Parcelable ====================
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel parcel, int flags) {
parcel.writeString(name);
parcel.writeString(address);
}
private Model(Parcel in) {
name = in.readString();
address = in.readString();
}
public static final Parcelable.Creator<Model> CREATOR = new Parcelable.Creator<Model>() {
public Model createFromParcel(Parcel in) {
return new Model(in);
}
public Model[] newArray(int size) {
return new Model[size];
}
};
... ...
Try this code and see if it helps.
