fragment OnItemClick:-

 listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                                long id) {

            Bundle bundle = new Bundle();
            ProdModel mProdModel = prodList.get(position);
            bundle.putSerializable("object", mProdModel);
            Intent intent = new Intent(getActivity(), DetailActivity.class);
            intent.putExtra("bundle", bundle);
            startActivityForResult(intent, 1);

        }

    });

详细 Activity ，

Bundle bundle = getIntent().getBundleExtra("bundle");
    if (bundle != null) {
        ProdModel model = (ProdModel) bundle.getSerializable("object");
    }

详细 Activity list ，

  <activity
        android:name="com.mass.mysample.DetailActivity"
        android:screenOrientation="portrait" />

使用 Picasso 加载图像，

 Picasso.with(this).load(model.getImage())
             .placeholder(R.drawable.logo_without)
             .fit().into(productimage);

模型类

public class ProdModel implements Serializable {
private String seller_id;
String name;
private String image;
private float price;
private float specialprice;
private String entity_id;
private String productNumQuantity;
private String storetitle;
private String description;
private String discount;
private String max_price;
private String store_name;
private String StoreUrl;

public String getProductNumQuantity() {
    return productNumQuantity;
}

public void setProductNumQuantity(String productNumQuantity) {
    this.productNumQuantity = productNumQuantity;
}

public String getDiscount() {
    return discount;
}

public void setDiscount(String discount) {
    this.discount = discount;
}

public String getMax_price() {
    return max_price;
}

public void setMax_price(String max_price) {
    this.max_price = max_price;
}

public String getStore_name() {
    return store_name;
}

public void setStore_name(String store_name) {
    this.store_name = store_name;
}

public String getStoreUrl() {
    return StoreUrl;
}

public void setStoreUrl(String storeUrl) {
    StoreUrl = storeUrl;
}

public String getStoretitle() {
    return storetitle;
}

public void setStoretitle(String storetitle) {
    this.storetitle = storetitle;
}

public String getSeller_id() {
    return seller_id;
}

public void setSeller_id(String seller_id) {
    this.seller_id = seller_id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getImage() {
    return image;
}

public void setImage(String image) {
    this.image = image;
}

public String getEntity_id() {
    return entity_id;
}

public void setEntity_id(String entity_id) {
    this.entity_id = entity_id;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public float getPrice() {
    return price;
}

public void setPrice(float price) {
    this.price = price;
}

public float getSpecialPrice() {
    return specialprice;
}

public void setSpecialPrice(float specialprice) {
    this.specialprice = specialprice;
}

}

从TabActivity到fragment的数据流，

1.I have a TabActivity with ViewPager and Fragment. 
2.In Fragment, I have a ListView.
3.The Data to fragment is passed from view pager adapter by set arguments.

我尝试过的解决方案

1.A POJO class that implements Serialization. 
2.I use Picasso to load the image from image URL. 
3.This exception is thrown when OnItemClick on ListView in fragment passes data to DetailActivity to show all passed data.
4.I get this exception after the DetailActivity load's image and other data then app suddenly crashes.
5.I pass data in Intent was all POJO Object with Id, Name, Image URL, Price etc.,

注意:-应用程序崩溃仅在NOUGAT

最后，我实现的修复

将 targetSdkVersion 从 25 更改为 23

更改后，我的应用程序在 Nougat 中也没有崩溃。

我所需要知道的是这个正确的解决方案或者是否有任何解决方法。

请指导正确的方法。

提前致谢。

您在 setArguments() 中向 Fragment 传递了太多数据。您的 Fragment 可以工作，但是当它尝试保存其实例状态时，它会溢出事务缓冲区。如果您的目标平台是 Android 7.0(API 24 或更高版本)，这会引发 RuntimeException 。为了保持向后兼容性并且不破坏现有应用程序，仅当您以 API 24 或更高版本为目标时才会使用新行为。如果您的目标 API < 24，则会捕获事务缓冲区溢出异常并静默忽略。这意味着您的数据不会被持久保存，您可能会(也可能不会)注意到这一点。

您的代码已损坏。您不应将大量数据传递给 setArguments() 中的 Fragment。您可以将数据保存在Activity中。当 Fragment 想要访问数据时，它总是可以这样:

// Get the owning Activity
MyActivity activity = (MyActivity)getActivity();
// Get the data from the Activity
List<Data> data = activity.getData();

在您的 Activity 中，编写一个 getData() 方法，该方法返回对 Fragment 所需的任何数据的引用。

通过这种方式，数据保存在Activity中，并且Fragment可以在需要时访问它。
