所以我不断收到此错误“由：java.io.NotSerializableException异常：android.net.Uri $ StringUri”当我按下按钮实现以下方法：

public void shareItems() { 

    StringBuilder dataString = new StringBuilder(); 

    String name = itemName.getText().toString(); 
    String price = itemPrice.getText().toString(); 
    String description = itemDescription.getText().toString(); 
    String location = itemLocation.getText().toString(); 


    dataString.append(" product: " + name + "\n"); 
    dataString.append(" price: " + price + "\n"); 
    dataString.append(" pick up location: " + location + "\n"); 
    dataString.append(" description: " + description); 

    Intent i = new Intent(Intent.ACTION_SEND); 

    i.setType("text/plain"); 
    i.putExtra(Intent.EXTRA_SUBJECT, "product for sale"); 
    i.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"}); 
    i.putExtra(Intent.EXTRA_TEXT, dataString.toString()); 

    try { 

     startActivity(Intent.createChooser(i, "share")); 

    } catch (ActivityNotFoundException e) { 
     Toast.makeText(getActivity(), "Please install a messaging app", 
       Toast.LENGTH_LONG).show(); 
    } 
} 

public void sendWhatsapp() { 

    StringBuilder dataString = new StringBuilder(); 

    String name = itemName.getText().toString(); 
    String price = itemPrice.getText().toString(); 
    String description = itemDescription.getText().toString(); 
    String location = itemLocation.getText().toString(); 


    dataString.append(" product: " + name + "\n"); 
    dataString.append(" price: " + price + "\n"); 
    dataString.append(" pick up location: " + location + "\n"); 
    dataString.append(" description: " + description); 

    Items item = new Items(); 
    item.setMobile(adapter.getMobile()); 
    mobile = item.getMobile(); 
    System.out.println(mobile); 


    Uri uri = Uri.parse("smsto:" + "0542001117"); 

    Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri); 
    sendIntent.putExtra(Intent.EXTRA_TEXT, dataString.toString()); 
    sendIntent.setPackage("com.whatsapp"); 



    try { 

     startActivity(Intent.createChooser(sendIntent, "Contact seller")); 

    } catch (ActivityNotFoundException e) { 
     Toast.makeText(getActivity(), "Please install WhatsApp", 
       Toast.LENGTH_LONG).show(); 
    } 


}

根本不使用任何Uri。它说这个错误在这个类中，它实现了serialiazable，但我不明白它是如何导致问题的，或者它是如何被这些按钮触发的。

public class Items implements Serializable{ 

private static final long serialVersionUID = 10L; 
private String itemDescription; 
private String itemLocation; 
private Uri itemImage; 
private String itemName; 
private int itemPrice; 
private int itemID; 
private String mobile; 


public String getMobile() { 
    return mobile; 
} 

public void setMobile(String mobile) { 
    this.mobile = mobile; 
} 



public static long getSerialVersionUID() { 
    return serialVersionUID; 
} 



public String getItemName() { 
    return itemName; 
} 

public void setItemName(String itemName) { 
    this.itemName = itemName; 
} 



public int getItemPrice() { 
    return itemPrice; 
} 

public void setItemPrice(int itemPrice) { 
    this.itemPrice = itemPrice; 
} 



public int getItemID() { 
    return itemID; 
} 

public void setItemID(int itemID) { 
    this.itemID = itemID; 
} 



public String getItemDescription() { 
    return itemDescription; 
} 

public void setItemDescription(String itemDescription) { 
    this.itemDescription = itemDescription; 
} 

public String getItemLocation() { 
    return itemLocation; 
} 

public void setItemLocation(String itemLocation) { 
    this.itemLocation = itemLocation; 
} 

public Uri getItemImage() { 
    return itemImage; 
} 

public void setItemImage(Uri itemImage) { 
    this.itemImage = itemImage; 
} 



public Items(String item, int price, int id, String description, String location, Uri image, String phone){ 

    itemName = item; 
    itemPrice = price; 
    itemID = id; 
    itemDescription = description; 
    itemLocation = location; 
    itemImage = image; 
    mobile = phone; 
} 

public Items(){ 

}

}

编辑：这是我使用的序列化：

public class CustomListviewAdapter extends ArrayAdapter<Items> { 

private int layoutResource; 
private Activity activity; 
static FragmentManager fragmentManager; 
private Context context; 

private ArrayList<Items> itemList = new ArrayList<>(); 

public CustomListviewAdapter(Activity act, int resource, ArrayList<Items> data) { 
    super(act, resource, data); 
    layoutResource = resource; 
    activity = act; 
    itemList = data; 
    notifyDataSetChanged(); 


} 

@Override 
public int getCount() { 
    return itemList.size(); 
} 

@Override 
public Items getItem(int position) { 
    return itemList.get(position); 
} 

@Override 
public int getPosition(Items item) { 
    return super.getPosition(item); 
} 

@Override 
public long getItemId(int position) { 
    return super.getItemId(position); 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 

    View row = convertView; 
    ViewHolder holder = null; 


    if (row == null || (row.getTag() == null)) { 

     LayoutInflater inflater = LayoutInflater.from(activity); 
     row = inflater.inflate(layoutResource, null); 

     holder = new ViewHolder(); 

     holder.itemName = (TextView) row.findViewById(R.id.name); 
     holder.itemPrice = (TextView) row.findViewById(R.id.calories); 
     holder.itemImage = (ImageView) row.findViewById(R.id.thumbnail); 

     row.setTag(holder); 

    }else { 

     holder = (ViewHolder) row.getTag(); 
    } 


    holder.item = getItem(position); 

    holder.itemName.setText(holder.item.getItemName()); 
    holder.itemImage.setImageURI(holder.item.getItemImage()); 
    holder.itemPrice.setText(String.valueOf(holder.item.getItemPrice())); 



    final ViewHolder finalHolder = holder; 
    row.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      android.support.v4.app.FragmentTransaction ft = 
        ((FragmentActivity)activity).getSupportFragmentManager().beginTransaction(); 
      ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN); 

      ItemDetails frag = new ItemDetails(); 

      Bundle mBundle = new Bundle(); 
      mBundle.putSerializable("userObj", finalHolder.item); 

      frag.setArguments(mBundle); 
      ft.replace(android.R.id.content, frag); 
      ft.addToBackStack(null); 
      ft.commit(); 



     } 
    }); 


    return row; 

} 

public class ViewHolder { 
    Items item; 
    TextView itemName; 
    TextView itemPrice; 
    ImageView itemImage; 

}

}

，并在所在班级导致崩溃的方法：

public class ItemDetails extends Fragment { 


private View view; 
private TextView itemName, itemLocation, itemPrice, itemDescription; 
private ImageView itemImage; 
private Button shareButton, sendWhatsapp; 
private int itemId;

    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

    itemName = (TextView) view.findViewById(R.id.detsItemName); 
    itemPrice = (TextView) view.findViewById(R.id.detsPrice); 
    itemLocation = (TextView) view.findViewById(R.id.detsItemLocation); 
    itemDescription = (TextView) view.findViewById(R.id.detsDescription); 
    itemImage = (ImageView) view.findViewById(R.id.itemImage); 
    shareButton = (Button) view.findViewById(R.id.detsShare); 
    sendWhatsapp = (Button) view.findViewById(R.id.sendWhatsappBtn); 

    Bundle mBundle = getArguments(); 

    Items item = (Items) mBundle.getSerializable("userObj"); 
    itemName.setText(item.getItemName()); 
    itemPrice.setText(valueOf(item.getItemPrice())); 
    itemLocation.setText(item.getItemLocation()); 
    itemDescription.setText(item.getItemDescription()); 
    itemImage.setImageURI(item.getItemImage()); 


    adapter = new DataBaseAdapter(getActivity()); 
    adapter.open(); 


    itemPrice.setTextSize(34.9f); 
    itemPrice.setTextColor(Color.BLUE); 

    shareButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      shareItems(); 
     } 
    }); 

    sendWhatsapp.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      sendWhatsapp(); 
     } 
    }); 


    return view; 

}

    Intent i = new Intent(Intent.ACTION_SEND); 

    i.setType("text/plain"); 
    i.putExtra(Intent.EXTRA_SUBJECT, "منتج للبيع"); 
    i.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"}); 
    i.putExtra(Intent.EXTRA_TEXT, dataString.toString()); 

    try { 

     startActivity(Intent.createChooser(i, "شارك")); 

    } catch (ActivityNotFoundException e) { 
     Toast.makeText(getActivity(), "المرجو تحميل برنامج ارسال", 
       Toast.LENGTH_LONG).show(); 
    } 
} 

public void sendWhatsapp() { 

    StringBuilder dataString = new StringBuilder(); 

    String name = itemName.getText().toString(); 
    String price = itemPrice.getText().toString(); 
    String description = itemDescription.getText().toString(); 
    String location = itemLocation.getText().toString(); 


    dataString.append(" المنتج: " + name + "\n"); 
    dataString.append(" السعر: " + price + "\n"); 
    dataString.append(" موقع الاستلام: " + location + "\n"); 
    dataString.append(" الوصف: " + description); 

    Items item = new Items(); 
    item.setMobile(adapter.getMobile()); 
    mobile = item.getMobile(); 
    System.out.println(mobile); 


    Uri uri = Uri.parse("smsto:" + "0542001117"); 

    Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri); 
    sendIntent.putExtra(Intent.EXTRA_TEXT, dataString.toString()); 
    sendIntent.setPackage("com.whatsapp"); 



    try { 

     startActivity(Intent.createChooser(sendIntent, "مراسلة البائع")); 

    } catch (ActivityNotFoundException e) { 
     Toast.makeText(getActivity(), "المرجو تحميل WhatsApp", 
       Toast.LENGTH_LONG).show(); 
    } 


}

}再次

编辑，logcat的：

在你的类Items您有：

private Uri itemImage;

如果一个类实现Serializable那么其所有成员变量的需要能够被序列化，其Uri不能。

您有几种选择：

声明itemImage瞬态

如果不要紧给你，如果itemImage仍设置，当你反序列化它，那么你可以将transient改性剂添加到它。这本讲述java忽略它，当它的序列化：

private transient Uri itemImage;

变化itemImage是一个字符串

取而代之的是开放的，你可以只使用一个String它代表了图像的路径。根据Uri的类型，以及如何使用它，你可能不会在所有

使用Parcelable需要它作为开放的，而不是串行化

这需要更多的工作，你必须手动创建的包裹，但它让您更好地控制对象如何“序列化”

瞬态的东西奏效！非常感谢！ – Yousef

它说的错误是在这个类实现serialiazable，但我不明白它是如何造成的问题

好，您正尝试序列化一个不支持的Uri。将其转换为字符串表示形式并从中转换或者，也许不要使用Serializable。
