android - 为什么 java.lang.Integer 在 Android Studio 的自动 Parcelable 实现中被忽略？

Question

这是由 Android Studio 生成的自动 Parcelable 实现。它以某种方式总是忽略类型为 Integer

的 resultCode

public class TestParceable implements Parcelable {

        private String message;
        private Integer resultCode; //an Integer   

    protected TestParceable(Parcel in) {
        message = in.readString();
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(message);
    }

    @Override
    public int describeContents() {
        return 0;
    }

    public static final Creator<TestParceable> CREATOR = new Creator<TestParceable>() {
        @Override
        public TestParceable createFromParcel(Parcel in) {
            return new TestParceable(in);
        }

        @Override
        public TestParceable[] newArray(int size) {
            return new TestParceable[size];
        }
    };
}

另一方面，如果我将 resultCode 的类型更改为 int，自动 Parcelable 实现会考虑它。

public class TestParceable implements Parcelable {

        private String message;
        private int resultCode; //an int

protected TestParceable(Parcel in) {
    message = in.readString();
    resultCode = in.readInt();
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(message);
    dest.writeInt(resultCode);
}

@Override
public int describeContents() {
    return 0;
}

public static final Creator<TestParceable> CREATOR = new Creator<TestParceable>() {
    @Override
    public TestParceable createFromParcel(Parcel in) {
        return new TestParceable(in);
    }

    @Override
    public TestParceable[] newArray(int size) {
        return new TestParceable[size];
    }
};

我是不是遗漏了什么或者这是 Android Studio 的错误？

Answer 1

这是一个错误 ( https://code.google.com/p/android/issues/detail?id=233034 )，已针对 Studio 2.4 修复。
