Passing arraylist of custom object to another activity

When a cell is clicked the object is added to an array. This array needs to be passed into another activity. For testing purposes I have passed the array that has only one object, the DoctorObject. Then in the next activity I get the name as a string using .getName() and display that in a toast. However the toast is empty. Here is some snippets of the code Object: public class DoctorObject implements Parcelable { private List<Object> mChildrenList; public DoctorObject(String name) { Docname = name; } public DoctorObject (Parcel in){ this.DocPic = in.readInt(); this.Docname= in.readString();

问题 I recently came across a very stupid (at least from my point of view) implementation inside Androids Parcel class. Suppose I have a simple class like this class Foo implements Parcelable{ private String[] bars; //other members public in describeContents(){ return 0; } public void writeToParcel(Parcel dest, int flags){ dest.writeStringArray(bars); //parcel others } private Foo(Parcel source){ source.readStringArray(bars); //unparcel other members } public static final Parcelable.Creator<Foo>

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . Can you tell me how to solve this? It throws a bad array length exception and after debugging, I found this method throws the Exception: --------------------------My Code----------------------------------- public class SingleModels implements Parcelable{ public String name; public String[] names ; @Override

Using an ArrayList<String> with a class that extends Parcelable

由 我与影子孤独终老i 提交于 2019-12-08 08:32:47
问题 I'm having trouble with reading an ArrayList of Strings with a class that implements Parcelable. I want to send 3 ArrayLists of Strings to a Fragment. Another thing I don't understand is how I'd use this class to actually send this data to a Fragment (I read somewhere else that you can use your own parcelable class to do this, but I don't know exactly how). Here is the relevant code, I'll put comments in the places I think I need help. package com.tsjd.HotMeals; import java.util.ArrayList;

Android - Problem with the Serializable interface

由 吃可爱长大的小学妹 提交于 2019-12-07 18:29:58

I know that I should
