Make ArrayList<ArrayList<Integer>> parcelable

Make ArrayList<ArrayList<Integer>> parcelable - android

I am trying to make the following Class parcelable. Usually, I do this by using the parcelabler website. But the website seems to have problems with the ArrayList> part. Does anybody know how to do it properly?
Thanks in advance!
package com.example.stoos.data;
import java.util.ArrayList;
import android.os.Parcel;
import android.os.Parcelable;
public class DataModelDiagrammDaten implements Parcelable {
ArrayList<String> Antworten = new ArrayList<String>();
ArrayList<ArrayList<Integer>> AntwortIDs = new ArrayList<ArrayList<Integer>>();
public ArrayList<String> getAntworten() {
return Antworten;
}
public ArrayList<ArrayList<Integer>> getAntwortIDs() {
return AntwortIDs;
}
public void setAntworten(ArrayList<String> antworten) {
Antworten = antworten;
}
public void setAntwortIDs(ArrayList<ArrayList<Integer>> antwortIDs) {
AntwortIDs = antwortIDs;
}
public DataModelDiagrammDaten(ArrayList<String> antworten,
ArrayList<ArrayList<Integer>> antwortIDs) {
super();
Antworten = antworten;
AntwortIDs = antwortIDs;
}
protected DataModelDiagrammDaten(Parcel in) {
if (in.readByte() == 0x01) {
Antworten = new ArrayList<String>();
in.readList(Antworten, String.class.getClassLoader());
} else {
Antworten = null;
}
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
if (Antworten == null) {
dest.writeByte((byte) (0x00));
} else {
dest.writeByte((byte) (0x01));
dest.writeList(Antworten);
}
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<DataModelDiagrammDaten> CREATOR = new Parcelable.Creator<DataModelDiagrammDaten>() {
#Override
public DataModelDiagrammDaten createFromParcel(Parcel in) {
return new DataModelDiagrammDaten(in);
}
#Override
public DataModelDiagrammDaten[] newArray(int size) {
return new DataModelDiagrammDaten[size];
}
};
}

I think it is a little late, but hope it's still useful for others.
I tried to write a two dimensional Array to Parcel like this:
public class Avatar implements Parcelable {
ArrayList<Integer> arrayList;
ArrayList<ArrayList<Integer>> arrayLists;
public Avatar() {
arrayLists = new ArrayList<>();
for (int i = 0; i < 10; i++) {
ArrayList<Integer> temp = new ArrayList<>();
for (int j = 0; j < 10; j++) {
temp.add(j);
}
arrayLists.add(temp);
}
arrayList = new ArrayList<>();
for (int i = 100; i < 104; i++) {
arrayList.add(i);
}
}
protected Avatar(Parcel in) {
arrayList = new ArrayList<>();
in.readList(arrayList, Integer.class.getClassLoader());
arrayLists = new ArrayList<>();
in.readList(arrayLists, ArrayList.class.getClassLoader());
}
public static final Creator<Avatar> CREATOR = new Creator<Avatar>() {
#Override
public Avatar createFromParcel(Parcel in) {
return new Avatar(in);
}
#Override
public Avatar[] newArray(int size) {
return new Avatar[size];
}
};
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeList(arrayList);
dest.writeList(arrayLists);
}
#Override
public String toString() {
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < arrayList.size(); i++) {
stringBuilder.append(arrayList.get(i) + " ");
}
for (int i = 0; i < arrayLists.size(); i++) {
for (int j = 0; j < arrayLists.get(i).size(); j++) {
stringBuilder.append(arrayLists.get(i).get(j) + " ");
}
}
return stringBuilder.toString();
}
}
And send the class to another Activity:
avatar = new Avatar();
Intent intent = new Intent();
intent.setClass(ParcelActivity.this, Parcel2Activity.class);
intent.putExtra("avatar", avatar);
startActivity(intent);
Receive in another Activity:
textView.setText(getIntent().getParcelableExtra("avatar") + "");
It works correctly:
test
What should be careful is that writing and reading for the field objects in Parcel must be in the same sequence.

EDIT:
Try to put the second ArrayList in another class like this:
public class IdsObject implements Parcelable {
ArrayList<Integer> ids;
public IdsObject(ArrayList<Integer> ids) {
this.ids = ids;
}
protected IdsObject(Parcel in) {
if (in.readByte() == 0x01) {
ids = new ArrayList<Integer>();
in.readList(ids, Integer.class.getClassLoader());
} else {
ids = null;
}
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
if (ids == null) {
dest.writeByte((byte) (0x00));
} else {
dest.writeByte((byte) (0x01));
dest.writeList(ids);
}
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<IdsObject> CREATOR = new Parcelable.Creator<IdsObject>() {
#Override
public IdsObject createFromParcel(Parcel in) {
return new IdsObject(in);
}
#Override
public IdsObject[] newArray(int size) {
return new IdsObject[size];
}
};
}
Then, use this class on your class like this:
public class DataModelDiagrammDaten implements Parcelable, Parcelable {
ArrayList<String> Antworten = new ArrayList<String>();
ArrayList<IdsObject> AntwortIDs = new ArrayList<IdsObject>();
protected DataModelDiagrammDaten(Parcel in) {
if (in.readByte() == 0x01) {
Antworten = new ArrayList<String>();
in.readList(Antworten, String.class.getClassLoader());
} else {
Antworten = null;
}
if (in.readByte() == 0x01) {
AntwortIDs = new ArrayList<IdsObject>();
in.readList(AntwortIDs, IdsObject.class.getClassLoader());
} else {
AntwortIDs = null;
}
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
if (Antworten == null) {
dest.writeByte((byte) (0x00));
} else {
dest.writeByte((byte) (0x01));
dest.writeList(Antworten);
}
if (AntwortIDs == null) {
dest.writeByte((byte) (0x00));
} else {
dest.writeByte((byte) (0x01));
dest.writeList(AntwortIDs);
}
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<DataModelDiagrammDaten> CREATOR = new Parcelable.Creator<DataModelDiagrammDaten>() {
#Override
public DataModelDiagrammDaten createFromParcel(Parcel in) {
return new DataModelDiagrammDaten(in);
}
#Override
public DataModelDiagrammDaten[] newArray(int size) {
return new DataModelDiagrammDaten[size];
}
};
}

Ok, I solved it. Here is the solution in case anybody else faces the same problem:
You can first make your class with an normal ArrayList (instead of ArrayList> ) parcelable with the website. Then take the following snippet an write it into the Constructor with the Parcel argument at the place, were the ArrayList was. Now change your ArrayList back to your ArrayList> and it should work.
if (in.readByte() == 0x01) {
IDs = new ArrayList<ArrayList<Integer>>();
Type collectionType = new TypeToken<ArrayList<Integer>>(){}.getType();
in.readList(IDs, collectionType.getClass().getClassLoader());
} else {
IDs = null;
}

Recycler view swaps items when i scroll them

I am developing the chatbot app. I am using the RecycleView to render the chat of user and bot. I have to show the user listview or text response depend upon his query. All is working until my RecyclerView get's scroll. Whenever my RecyclerView gets scroll it changes the item position. I search a lot and applied every solution but not able to solve my issue.

How to access the ArrayList present in Adapter in Activity

I have a listview in which in each row I have a checkbox along with details o persons. Now on clicking checkboxes, I want to store the id of those persons in arrayList which I am able to store but the arrayList id in adapter. I want to access the arrayList in activity because I want to take a button in activity on clicking which I want to send ids of all the selected persons to another activity. How do I do that.
My code is below:
SendWorkList.java
public class SendWorkList extends AppCompatActivity {
List<SendWorkRow> send_work_array_list;
ListView send_work_list;
JSONArray send_work_jsonArray1,send_work_result_jsonArray2;
JSONObject send_work_jsonObject1,send_work_result_jsonArray2_i;
String[] send_work_id,send_work_name,send_work_bankaccount,send_work_ifsc,send_work_contacts,send_work_department,send_work_cardnumber,send_work_cardexpiry,send_work_cardcvv;

Create one method in adapter like
public class SendWorkAdapter extends BaseAdapter {
public List<SendWorkRow> getAllWorkRows() {
return send_work_array_list;
}
}
and access this method using adapter instance in activity.
Another way is you can write a method in Adapter where you will find all selected ids in a List and return. So whenever you will require list of selected ids, call this method from Activity and do your task. like
public class SendWorkAdapter extends BaseAdapter {
public List<SendWorkRow> getAllSelectedWorkRows() {
// write your logic to find selected rows
return result;
}
}

Recyclerview Inconsistency detected. Invalid view holder adapter positionViewHolder

In my app right now I am working with two lists. One is a List of an Object and the other the a List of Lists of the same object. I have a method in my Activity that transforms a list of Object into a List of Lists of object. And to my adapter I am passing the list of lists through this call:
mAdapter.swap(transformList(pipe.mList));
The method swap is responsible for passing the transformed list to my Adapter:
public void swap(List<List<Feed>> feedList) {
if (finallist == null) {
finallist = new ArrayList<>();
}
finallist.clear();
finallist.addAll(feedList);
}
The transformation checks if there are images in a row and puts all of them inside a single list (I am trying to implement something similar to WhatsApp image grouping). So I have a bunch of messages, they can be text messages, files, images, etc. In case of the last one, I group them in a single list.
Let me give a scenario as an example:
I have four images and 1 text message in my original array. The transformation puts all the four images into a single List of objects and de text message in another list of objects (both of them are inserted in my list of lists).
I thought about two ways to handle this transformation: 1 - do it inside the Adapter and 2 - do it in my Activity and pass the modified list to the Adapter. Each one of this solutions generated a different problem.
By following the steps in 1, I was able to display all of the content almost in the way I wanted. The grouping was working just fine! The problem is that if the original array had a length equals to 30, and the transformed array's length was decreased to 12. The RecyclerView would show all of the remaining 18 items as empty states (so after the transformation it wasn't handling the removing items properly).
By following the steps in 2, I was not able to display all of the content. Just the first element of my array. And I would get a IndexOutOfBoundsException in RecyclerView happens java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder error message. But I was not able to identify the problem. I checked many questions here and none of them helped me.

My problem was caused by the BaseSkeletonAdapter<Feed> that my FeedAdapter was extending. BaseSkeletonAdapter was using the original list and not the List of Lists I had to use. So I created a new class SkeletonAdapterFeed that is basically equal to the previous one, but the new one is receiving a List of Lists instead of just the List.
I know that it sounds a little confusing. I don't have full understanding of the project I am working right now so that's why I don't know everything about the classes, etc.

notifyDataSetChanged does not update the listView of custom objects after sorting

I am trying to sort the collection in custom arrayadapter and making a call to update the view . However, the view does not gets updated.
There are two values over which I want to sort (date and amount) and have a custom comparators for them.
I can see that the data itself has changed (i.e if a list item has gone outside of view after sorting and when it gets the view, the data it show is the correct data that should exist after sorting).
The second question is about the filter. The way the filter is implemented right now, it does not update the views either.
Here is code
public class SearchActivity extends BListActivity {
private Bundle sessionInfo;
private TransactionDetailsHandler transactionDetailsHandler = new TransactionDetailsHandler();
private static boolean ascDate = false;
private static boolean ascAmount = false;

}
adapter.notifyDataSetChanged();
}
});

Passing vector of Class<?> objects to other activity - in Android

I'd like to ask what I'm doing wrong if I want to pass such data to other class:
String [] codes = {"code"};
Class<?> [] classes = { TestActivity.class };
Intent i = new Intent();
Pack p = new Pack();
p.eat(classes,codes);
i.putExtra("com.mbar", p);
i.setClass(this, CaptureActivity.class);
startActivity(i);
}
}
Later in other activity I try it to unpack like that:
Bundle b = getIntent().getExtras();
Pack p = (Pack)b.getParcelable("com.mbar");
if(p!=null){
classes = p.getClasses();
codes = p.getNames();
The Pack class which is Parcelable looks like:
package com.mbar;
import android.os.Parcel;
import android.os.Parcelable;
public class Pack implements Parcelable {
Class<?>[] classes;
String [] codes;
public void eat(Class<?>[] classes,String [] codes){
this.classes = classes;
this.codes = codes;
}
public Class<?>[] getClasses(){
return this.classes;
}
public String [] getNames(){
return this.codes;
}
#Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
}
}

String [] codes = {"code"};
Class<?> [] classes = { TestActivity.class };
Intent i = new Intent();
Pack p = new Pack(classes,codes);
i.putExtra("com.mbar", p);
i.setClass(this, CaptureActivity.class);
startActivity(i)
Pack p = (Pack)getIntent().getParcelableExtra("com.mbar");
if(p!=null){
classes = p.getClasses();
codes = p.getNames();
public static class Pack implements Parcelable {
Class<?>[] classes;
String[] codes;
public Pack(Class<?>[] classes, String[] codes) {
this.classes = classes;
this.codes = codes;
}
public Pack(Parcel in) {
int len = in.readInt();
String[] classnames = new String[len];
in.readStringArray(classnames);
classes = new Class<?>[classnames.length];
for (int i = 0; i < classnames.length; i++) {
try {
classes[i] = Class.forName(classnames[i]);
} catch (ClassNotFoundException e) {
}
}
len = in.readInt();
codes = new String[len];
in.readStringArray(codes);
}
public Class<?>[] getClasses() {
return this.classes;
}
public String[] getNames() {
return this.codes;
}
#Override
public int describeContents() {
return 0;
}
public static final Parcelable.Creator<Pack> CREATOR = new Parcelable.Creator<Pack>() {
public Pack createFromParcel(Parcel in) {
return new Pack(in);
}
public Pack[] newArray(int size) {
return new Pack[size];
}
};
#Override
public void writeToParcel(Parcel dest, int flags) {
String[] classnames = new String[classes.length];
for (int i = 0; i < classes.length; i++) {
classnames[i] = classes[i].getName();
}
dest.writeInt(classnames.length);
dest.writeStringArray(classnames);
dest.writeInt(codes.length);
dest.writeStringArray(codes);
}
}
