Android 无法从一个活动检索到另一个活动的包实现类

我有一个名为Weekly Result的类，它实现了Parcel接口。将地块对象传递给其他活动时，检索该地块对象时遇到问题

这是我每周的课程：

这里是我发送目标的地方，目的是：

public void GoToWeeklyTopic(View v) {
    Intent intent = new Intent();
    intent.setClass(HomeActivity.this, Topic_of_the_week.class);

    Bundle b = new Bundle();
    WeeklyTopicResult w = weeks;

    // Puts the weeklyresult parcel class into bundle
    b.putParcelable("WeeklyContent", w);

    intent.putExtras(b);
    startActivity(intent);
}

下面是我尝试接收包裹对象的活动类：

ImageView weekImg;
TextView title;
TextView ContentText;
WeeklyTopicResult week= new WeeklyTopicResult();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_topic_of_the_week);

    Bundle extras = getIntent().getExtras();
            //Here I am receiving an error
    week =extras.getParcelable("WeeklyContent");


    weekImg = (ImageView) findViewById(R.id.imageView1);
    title = (TextView) findViewById(R.id.txt_MainTitle);
    ContentText = (TextView) findViewById(R.id.txt_page_content_topicweek);

    title.setText(week.Title.EnglishValue);
    ContentText.setText(week.Text.EnglishValue);
    weekImg.setImageBitmap(week.ImageSource);
    // String FullPath = RetrieveData_Preference("WeeklyTopicUrl") + Url;
    // getImage(FullPath);

}

我甚至试着把这个物体扔回去，但仍然有一个错误。Logcat错误向我显示了这个错误，但我已经为weeklyresult实现了一个creater类

LogCat错误：

我在这里做错了什么？

来自文档：

实现Parcelable接口的类还必须具有名为CREATOR的静态字段，该字段是实现Parcelable.CREATOR接口的对象

因此，将此字段添加到您的多语言类：

你必须始终按照你写的顺序阅读：

@Override
public void writeToParcel(Parcel dest, int flags) {
    // TODO Auto-generated method stub
    Log.v("WeekData", "WriteToParcel..." + flags);
    dest.writeString(ID);
    dest.writeString(ImageUrl);
    dest.writeString(PublishOn);
    dest.writeParcelable(Title, flags);
    dest.writeParcelable(Text, flags);
    dest.writeParcelable(ImageSource, flags);

}

public void ReadFromParcel(Parcel obj) {
    Log.v("WeeklyClaas",
            "ParcelData(Parcel source): time to put back parcel data");
    ID = obj.readString();
    //these were lower
    ImageUrl = obj.readString();
    PublishOn = obj.readString();
    Title = (MultiLingual) obj.readParcelable(MultiLingual.class
            .getClassLoader());
    Text = (MultiLingual) obj.readParcelable(MultiLingual.class
            .getClassLoader());
    ImageSource = (Bitmap) obj
            .readParcelable(Bitmap.class.getClassLoader());
}

... 通过查看堆栈跟踪可以很容易地找到：android.os.BadParcelableException:parcelableprotocol需要一个名为Creator的Parcelable.Creator对象……这同样适用于WeeklyTopicResult类。它还必须有一个初始化为new WeeklyTopicResultParcelCreateRhy的静态创建者字段。你能给我一些示例吗？因为我在两个类中都创建了一个静态变量。它一直给我错误。我按照你的建议重新排列了代码。我仍然无法检索包裹对象。

ImageView weekImg;
TextView title;
TextView ContentText;
WeeklyTopicResult week= new WeeklyTopicResult();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_topic_of_the_week);

    Bundle extras = getIntent().getExtras();
            //Here I am receiving an error
    week =extras.getParcelable("WeeklyContent");


    weekImg = (ImageView) findViewById(R.id.imageView1);
    title = (TextView) findViewById(R.id.txt_MainTitle);
    ContentText = (TextView) findViewById(R.id.txt_page_content_topicweek);

    title.setText(week.Title.EnglishValue);
    ContentText.setText(week.Text.EnglishValue);
    weekImg.setImageBitmap(week.ImageSource);
    // String FullPath = RetrieveData_Preference("WeeklyTopicUrl") + Url;
    // getImage(FullPath);

}

public static final MyMultiLingualParcelCreator CREATOR = new MyMultiLingualParcelCreator();

@Override
public void writeToParcel(Parcel dest, int flags) {
    // TODO Auto-generated method stub
    Log.v("WeekData", "WriteToParcel..." + flags);
    dest.writeString(ID);
    dest.writeString(ImageUrl);
    dest.writeString(PublishOn);
    dest.writeParcelable(Title, flags);
    dest.writeParcelable(Text, flags);
    dest.writeParcelable(ImageSource, flags);

}

public void ReadFromParcel(Parcel obj) {
    Log.v("WeeklyClaas",
            "ParcelData(Parcel source): time to put back parcel data");
    ID = obj.readString();
    //these were lower
    ImageUrl = obj.readString();
    PublishOn = obj.readString();
    Title = (MultiLingual) obj.readParcelable(MultiLingual.class
            .getClassLoader());
    Text = (MultiLingual) obj.readParcelable(MultiLingual.class
            .getClassLoader());
    ImageSource = (Bitmap) obj
            .readParcelable(Bitmap.class.getClassLoader());
}
