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＆LT;模型与GT; mModelList =新的ArrayList＆LT;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＆LT;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。

  ERROR / AndroidRuntime（11109）：致命异常：主要    了java.lang.RuntimeException：无法启动活动ComponentInfo {测试/ test.activities.Bbbb}了java.lang.RuntimeException：地块android.os.Parcel@405585d0：解组未知类型code 7667810偏移144    在android.app.ActivityThread.performLaunchActivity（ActivityThread.java:1651）    在android.app.ActivityThread.handleLaunchActivity（ActivityThread.java:1667）    在android.app.ActivityThread.access $ 1500（ActivityThread.java:117）    在android.app.ActivityThread $ H.handleMessage（ActivityThread.java:935）    在android.os.Handler.dispatchMessage（Handler.java:99）    在android.os.Looper.loop（Looper.java:123）    在android.app.ActivityThread.main（ActivityThread.java:3687）    在java.lang.reflect.Method.invokeNative（本机方法）    在java.lang.reflect.Method.invoke（Method.java:507）    在com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:842）    在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:600）    在dalvik.system.NativeStart.main（本机方法）    了java.lang.RuntimeException：地块android.os.Parcel@405585d0：由解组造成未知类型code 7667810偏移144    在android.os.Parcel.readValue（Parcel.java:1913）    在android.os.Parcel.readListInternal（Parcel.java:2092）    在android.os.Parcel.readArrayList（Parcel.java:1536）    在android.os.Parcel.readValue（Parcel.java:1867）    在android.os.Parcel.readMapInternal（Parcel.java:2083）    在android.os.Bundle.unparcel（Bundle.java:208）    在android.os.Bundle.getParcelableArrayList（Bundle.java:1144）    在test.activities.Bbbb.onCreate（Bbbb.java:52）    在android.app.Instrumentation.callActivityOnCreate（Instrumentation.java:1047）    在android.app.ActivityThread.performLaunchActivity（ActivityThread.java:1615）    ... 11更多 

Line52是

 的ArrayList＆LT;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＆LT;模型与GT; CREATOR =新Parcelable.Creator＆LT;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]  }};} 

解决方案

您Parceleble实现看起来不正确的我，的 API 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＆LT;模型与GT; CREATOR =新Parcelable.Creator＆LT;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.
