java - 无法将 Parcelable 放入 bundle 中

Question

我的问题很简单。我想通过包和 Parcelable 将对象列表从 Activity 传递到 Fragment。

基本上，我从 MainActivity 进行一个简单的改造调用，获取对象列表作为答案，然后将其传递给 fragment 。

我已经为我的对象类实现了 Parcelable，但它不起作用。

public class Result implements Parcelable {

// Variables
@SerializedName("geometry")
@Expose
private Geometry geometry;
@SerializedName("icon")
@Expose
private String icon;
@SerializedName("id")
@Expose
private String id;
@SerializedName("name")
@Expose
private String name;
@SerializedName("opening_hours")
@Expose
private OpeningHours openingHours;
@SerializedName("photos")
@Expose
private List<Photo> photos = new ArrayList<Photo>();
@SerializedName("place_id")
@Expose
private String placeId;
@SerializedName("rating")
@Expose
private Double rating;
@SerializedName("reference")
@Expose
private String reference;
@SerializedName("scope")
@Expose
private String scope;
@SerializedName("types")
@Expose
private List<String> types = new ArrayList<String>();
@SerializedName("vicinity")
@Expose
private String vicinity;
@SerializedName("price_level")
@Expose
private Integer priceLevel;

// Constructor
public Result(Geometry geometry, String icon, String id, String name, OpeningHours openingHours, List<Photo> photos, String placeId, Double rating, String reference, String scope, List<String> types, String vicinity, Integer priceLevel) {
    this.geometry = geometry;

// Parcelable

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

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeParcelable(this.geometry, flags);
    dest.writeString(this.icon);
    dest.writeString(this.id);
    dest.writeString(this.name);
    dest.writeParcelable(this.openingHours, flags);
    dest.writeTypedList(this.photos);
    dest.writeString(this.placeId);
    dest.writeValue(this.rating);
    dest.writeString(this.reference);
    dest.writeString(this.scope);
    dest.writeStringList(this.types);
    dest.writeString(this.vicinity);
    dest.writeValue(this.priceLevel);
}

protected Result(Parcel in) {
    this.geometry = in.readParcelable(Geometry.class.getClassLoader());
    this.icon = in.readString();
    this.id = in.readString();
    this.name = in.readString();
    this.openingHours = in.readParcelable(OpeningHours.class.getClassLoader());
    this.photos = in.createTypedArrayList(Photo.CREATOR);
    this.placeId = in.readString();
    this.rating = (Double) in.readValue(Double.class.getClassLoader());
    this.reference = in.readString();
    this.scope = in.readString();
    this.types = in.createStringArrayList();
    this.vicinity = in.readString();
    this.priceLevel = (Integer) in.readValue(Integer.class.getClassLoader());
}

public static final Parcelable.Creator<Result> CREATOR = new Parcelable.Creator<Result>() {
    @Override
    public Result createFromParcel(Parcel source) {
        return new Result(source);
    }

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

以及MainActivity方法调用(简化)

public void initRetrofitandCall(double latitude, double longitude, int PROXIMITY_RADIUS) {
GoogleApiInterface service = GoogleMapsClient.getClient().create(GoogleApiInterface.class);
Call<Example> call = service.getNearbyRestaurants("restaurant", latitude + "," + longitude, PROXIMITY_RADIUS);
call.enqueue(new Callback<Example>() {
        @Override
        public void onResponse(Call<Example> call, Response<Example> response) {
            // Response List (working as intended)
            List<Result> listTest = response.body().getResults();
            Log.w("Nearby Restaurants", new GsonBuilder().setPrettyPrinting().create().toJson(listTest));  

            // Create bundle and put listTest in it (not working)
            Bundle bundle = new Bundle();
            bundle.putParcelable("valuesArray", listTest);

            try {

            } catch (Exception e) {
                Log.d("onResponse", "There is an error");
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(Call<Example> call, Throwable t) {
            Log.d("onFailure", t.toString());
        }

    });

}

bundle.putParcelable("valuesArray", listTest);说“需要错误的第二个参数类型 android.os.Parcelable

我的所有模型类都实现了 Parcelable，我只显示 Result.class，以免帖子太长。我也尝试过使用可序列化的方式，并且遇到了同样的问题。好像 Parcelable 或 Serialized 没有在我的模型类中实现。

非常感谢您为我提供的任何帮助。

您需要使用ParcelableArrayList将列表放入包中

bundle.putParcelableArrayList("valuesArray", listTest);
