我有這樣的問題,它在寫入包裹後重新創建自定義數據類型的數組。在Android中從包中打開自定義數據類型的錯誤
playerwear被聲明爲這樣:
private Wearable playerWear[] = new Wearable[5];
這是把它寫入在父類包裹的行。 它是類型可穿戴的陣列具有5個元素
parcel.writeArray(playerWear);
這是從包裹讀取它(溫度是父的一個空的數據元素,並具有填充在相同的方式波紋管的所有元素的行。所有其他人共同)
temp.playerWear = (Wearable[])source.readArray(Wearable.class.getClassLoader());
這是在可穿戴數據類型中定義的的包裹界面的代碼:
@Override
public int describeContents()
{
return 0;
}
/**
* This is the main method of the Parcelable Interface. This packs everything
* up into the parcel that will be used in the next activity
* @param parcel the parcel that will be passed to the next activity
* @param i used to keep track of the size...I think
*/
@Override
public void writeToParcel(Parcel parcel, int i)
{
parcel.writeString(slotName);
parcel.writeParcelable(heldItem, i);
if (holdingItem)
parcel.writeString("True");
else
parcel.writeString("False");
}
/**
* This is the method that takes the passed parcel and rebuilds it so that it can be used
* @param source the passed parcel
* @return the reconstructed data type
*/
public static Wearable recreateParcel(Parcel source)
{
Wearable temp = new Wearable();
temp.slotName = source.readString();
temp.heldItem = (Item) source.readParcelable(Item.class.getClassLoader());
String bool = source.readString();
if(bool.equals("True"))
temp.holdingItem = true;
else
temp.holdingItem = false;
return temp;
}
/**
* Not truly sure what this is but I think this is similar to the classLoader
*/
public static final Parcelable.Creator CREATOR = new Parcelable.Creator()
{
/**
* Calls the method that I created to recreate the Data type
* @param in the passed parcel
* @return s the return of the recreateParcel method
*/
public Wearable createFromParcel(Parcel in)
{
return recreateParcel(in);
}
/**
* Called if the custom data type is in an array
* @param size the size of the array. Used to figure out how many elements are needed
* @return an Array of the Data type
*/
public Wearable[] newArray(int size)
{
return new Wearable[size];
}
};
最後這錯誤,這是給我,
造成的:java.lang.ClassCastException:java.lang.Object繼承[]不能被轉換爲com.rtbd.storytime.Wearable []
請如果我忘記了解決此問題所需的任何重要信息,請發帖。
謝謝!
