开始活动android.os.TransactionTooLargeException时发生异常:数据包裹大小 [英] Exception when starting activity android.os.TransactionTooLargeException: data parcel size
问题描述
使用大量额外数据创建意图
Creating intent with a large amount of data in extras
public static Intent createIntent(Context context, List<PhotoItem> gallery, int indexOf) {
Intent intent = new Intent(context, GalleryViewActivity.class);
intent.putExtra(EXTRA_PHOTO_INDEX, indexOf);
intent.putExtra(EXTRA_PHOTO_OBJECT, new Gson().toJson(gallery));
return intent;
}
然后运行活动:
startActivity(createIntent(...
使用错误崩溃应用程序:
crashes application with error:
Exception when starting activity android.os.TransactionTooLargeException: data parcel size...
当列表中的数据太大时,如何避免此类错误?
How to avoid such errors when data is too large in the list?
推荐答案
您正在通过Intent
将整个List<PhotoItem>
传递给您的GalleryViewActivity
.因此,您的List<PhotoItem>
列表可能包含许多数据.因此有时系统无法一次处理大量数据.
You are passing whole List<PhotoItem>
to your GalleryViewActivity
with Intent
. So it might possible that your list of List<PhotoItem>
can have many data. So sometime system can not handle much data to transfer at a time.
请避免使用Intent传递大量数据.
Please avoid to pass large amount of data with Intent.
您可以使用SharedPreferences
存储阵列列表,并在其他活动中检索该列表.
You can use SharedPreferences
to store your array list and retrieve the same on other activity.
使用以下方法初始化您的SharedPreferences:
Initialize your SharedPreferences using:
SharedPreferences prefrence = PreferenceManager.getDefaultSharedPreferences(context);
Editor editor = prefrence.edit();
您可以使用这种方式将列表存储在Preference变量中
You can use this way to store list in Preference variable
public static Intent createIntent(Context context, List<PhotoItem> gallery, int indexOf) {
Intent intent = new Intent(context, GalleryViewActivity.class);
intent.putExtra(EXTRA_PHOTO_INDEX, indexOf);
editor.putString("GallaryData", new Gson().toJson(gallery));
editor.commit();
return intent;
}
现在在您的GalleryViewActivity.java文件中
Now in your GalleryViewActivity.java file
SharedPreferences prefrence = PreferenceManager.getDefaultSharedPreferences(context);
Editor editor = prefrence.edit();
String galleryData = prefrence.getString("GallaryData", "");
List<PhotoItem> listGallery = new Gson().fromJson(galleryData, new TypeToken<List<PhotoItem>>() {}.getType());
您将在listGallery变量中拥有列表.您可以像现在使用的一样检索索引.
You will have your list in listGallery variable. You can retrieve your index as the same way you are using right now.
