问题 I\'m trying to make an ArrayList Parcelable in order to pass to an activity a list of custom object. I start writing a myObjectList class which extends ArrayList<myObject> and implement Parcelable . Some attributes of MyObject are boolean but Parcel don\'t have any method read/writeBoolean . What is the best way to handle this? 回答1: Here's how I'd do it... writeToParcel: dest.writeByte((byte) (myBoolean ? 1 : 0)); //if myBoolean == true, byte == 1 readFromParcel: myBoolean = in.readByte() !=

Android Class Parcelable with ArrayList

由 こ雲淡風輕ζ 提交于 2019-11-26 10:36:02
问题 I have an android project where I have a class. In that class is an ArrayList<Choices> . I will be getting some XML, parsing it out, then making objects out of it which I will be passing to another activity. I\'m choosing Parcelable for this. Is Parcelable a good choice? Am I doing everything correctly? I\'m not familiar really with Parcelable. My ArrayList is of another class that I made within this class. Will it properly pass that ArrayList of objects to the Parcel with it not extending

Parcelable and inheritance in Android

由 心已入冬 提交于 2019-11-26 10:26:02
问题 I got an implementation of Parcelable working for a single class that involves no inheritance. I have problems figuring out the best way to implement the interface when it come to inheritance. Let\'s say I got this : public abstract class A { private int a; protected A(int a) { this.a = a; } } public class B extends A { private int b; public B(int a, int b) { super(a); this.b = b; } } Question is, which is the recommended way to implement the Parcelable interface for B (in A? in both of them?

Problem unmarshalling parcelables

问题 I\'ve got a few classes that implement Parcelable and some of these classes contain each other as properties. I\'m marshalling the classes into a Parcel to pass them between activities. Marshalling them TO the Parcel works fine, but when I try to unmarshall them I get the following error: ... AndroidRuntime E Caused by: android.os.BadParcelableException: ClassNotFoundException when unmarshalling: schemas.Arrivals.LocationType AndroidRuntime E at android.os.Parcel.readParcelable(Parcel.java

Is using Serializable in Android bad?

由 老子叫甜甜 提交于 2019-11-26 06:20:51
问题 I\'ve been reading a lot of posts and articles extolling the speed of Parcelable over Serializable. I\'ve been using both for a while to pass data between Activities through Intents, and have yet to notice any speed difference when switching between the two. The typical amount of data I have to transfer is 5 to 15 nested objects with 2 to 5 fields each. Since I have about 30 classes which must be transferable, implementing Parcelable requires a lot of boilerplate code that adds maintenance
