IndexOutOfBoundsException when making one Arraylist equal to another

I am trying to filter my RecyclerView using SearchView by following this guide: https://www.geeksforgeeks.org/searchview-in-android-with-recyclerview/
However, I am getting an IndexOutOfBoundsException when making one Arraylist equal to another, which I believe is happening at this portion of the code here:
public void filterList(ArrayList filteredlist) {
// below line is to add our filtered
// list in our course array list.
book_title = filteredlist;
// below line is to notify our adapter
// as change in recycler view data.
notifyDataSetChanged();
}
Here is the full code for my adapter class:

Use onActivityResult in RecyclerViewAdapter

I am trying to use onActivityResult in my RecyclerViewAdapter. But I get the error that the 'The method does not override from its superclass'. I tried implementing the interface but onActivityResult never gets called. I have already searched enough on the StackOverflow questions like this one but couldn't find anything helpful.

myImageAdapter.add(file.getAbsolutePath());
}
}
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String result = imagePaths.get(position);
Intent returnIntent = new Intent();
returnIntent.putExtra("result", result);
setResult(showImages.RESULT_OK, returnIntent);
finish();
}
});
}
}

The RecyclerView.ViewHolder class does not contain a definition of an onActivityResult method that it can override.
onActivityResult, as far as I understand, only appears as a method of the Activity & Fragment classes.
Move the code
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Bitmap bitmap;
if (requestCode == 1) {
if (resultCode == showImages.RESULT_OK) {
String result = data.getStringExtra("result");
Toast.makeText(this.context, "Clicked item is " + result, Toast.LENGTH_SHORT).show();
bitmap = BitmapFactory.decodeFile(result);
RecyclerViewHolder.img_profile.setImageBitmap(bitmap);
}
if (resultCode == showImages.RESULT_CANCELED) {
//Write your code if there's no result
}
}
}
to the class that initiated the call to showImages. I noticed that showImages closes when item is clicked.
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String result = imagePaths.get(position);
Intent returnIntent = new Intent();
returnIntent.putExtra("result", result);
setResult(showImages.RESULT_OK, returnIntent);
finish();
}
});

You have to override onActivityResult in your activity wich contains the recyclerview not in viewholder class

You must implement onActivityResult in your activity class not in RecyclerViewAdapter. This method is used from your activity to retrieve data from other intents/activities that have started from your activity and normally
it has no place inside RecyclerViewAdapter.

you should use onActivityForResult in activity ,and create interface to handle action ,logic - adapter only display view.

favorite Recycler view updates only on relaunching app

I developed a word app that contains English vocabularies and users can add their favorite word by clicking on a floating button. Every time my favorite list has at list one item it is updated but when it's empty it doesn't show anything but when I run app again list updates.
if you need any code let me know to send it .
UPDATE:
Inner page :
selectDb();
if(selectFavoriteState()){
favorite.setImageResource(R.drawable.ic_favorite_like);
}else {
favorite.setImageResource(R.drawable.ic_favorite_maylike);
}
favorite.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (selectFavoriteState()){
favorite.setImageResource(R.drawable.ic_favorite_maylike);
updateUnfavorited();
}else {
favorite.setImageResource(R.drawable.ic_favorite_like);
updateFavorited();
}
}
});
private void selectDb(){
destpath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/ielts/";
database = SQLiteDatabase.openOrCreateDatabase(destpath + "/md_book.db", null);
}
private boolean selectFavoriteState(){
#SuppressLint("Recycle") Cursor cursor = database.rawQuery("SELECT * FROM main WHERE id = " + id, null);
while (cursor.moveToNext()){
favoriteState = cursor.getString(cursor.getColumnIndex("fav"));
}
return favoriteState.equals("1");
}

In your FloatingActionButton onClick method after you save the new item in your database, insert your new item into your recyclerview datasource list and call notifyDatasetChanged() on the adapter.

Choice 1: in onResume() stub of MainActivity, call selectList() and selectFavorite() and then load the PageFragment again so that the new list is loaded properly.
This is the shortest wayout but this approach is very much unoptimized and is not recommended.
Choice 2: You will have to insert the new item in database as well as add it to the List and then call notifyDatasetChanged
In MainActivity within methods selectList() and selectFavorite() after you perform list.add(struct) and favourite.add(struct) respectively, you will have to call notifyDatasetChanged() for the Adapter.
But the problem is your RecyclerView is in the PageFragment whereas you're populating the list in MainActivity.
So move your selectList() and selectFavorite() to PageFragment where you first initialize the RecylerView then, set the Adapter and then populate the list and finally call notifyDatasetChanged() on your adapters.

Failed Binder Transaction is Ruining Entire Widget

In my widget, I am constantly getting this error:
11-02 09:35:10.613: D/D&D(1557): onCreate called
11-02 09:35:10.933: E/JavaBinder(1557): !!! FAILED BINDER TRANSACTION !!!
11-02 09:35:10.933: D/AppInfoAdapter(1557): top
No matter what I seem to do (I've tried cutting down bitmap sizes, making bitmaps static, commenting out parts of my coding to see where the error was (which didn't help at all by the way)), I always get this error. What this error is causing is that it makes my listView of the users installed applications not show up at all (it's just white space) in a sliding drawer. All my links and other classes work just fine. (But my listView is the center piece and major function of my entire widget.)
I'm at a loss now so I am just going to post the three suspected classes that I've concluded this is steming from (because all the other classes work fine).
Please note that some code is commented out (such as coding for drag and drop functionality because my real device doesn't support honeycomb. I will implement that code when my listView starts working again however)

(Thanks for reading all of this too, I know it was a lot)
Here is my Utilities class:
package com.example.awesomefilebuilderwidget;
import java.util.List;
import android.content.Context;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
public class Utilities {
/*
* Get all installed application on mobile and return a list
* #param c Context of application
* #return list of installed applications
*/
public static List<PackageInfo> getInstalledApplications(Context c) {
return c.getPackageManager().getInstalledPackages(PackageManager.GET_ACTIVITIES);
}

PackageManager methods, like getInstalledPackages(), can result in a binder transaction error, if the sum total of information being returned is greater than 1MB.
One way to mitigate this is to pass in no flags (e.g., skip PackageManager.GET_ACTIVITIES) to reduce the amount of data in the first call. Then, for those packages where you need the additional detail, call getPackageInfo() to get the details for a specific package. While this does involve multiple IPC round-trips, and therefore is slower, it will help prevent you from blowing out the 1MB-per-transaction limit.

It turned out that I was recieving too much information from the packageManager when I was getting the list of installed applications i.e.
Utilities.getInstalledApplications(this)
In my Utilities class. So then I thought that instead of getting ALL of the installed applications, that I should just get the users installed applications (excluding the system ones that are pointless for my use anyways). Here is the updated class:
public class Utilities {
/*
* Get all installed application on mobile and return a list
* #param c Context of application
* #return list of installed applications
*/
public static List<ResolveInfo> getInstalledApplications(Context c) {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
return c.getPackageManager().queryIntentActivities(intent, PackageManager.GET_ACTIVITIES);
}
Then of course any list with
<PackageInfo>
had to be changed to
<ResolveInfo>
but it worked like a charm!

Retrieve item from Spinner and put Some conditions

i have 2 arrays first for Hours and second for minutes, this is my arrays declare it in string.xml
` <string-array name="feedbacktypelist">
<item>#string/hr0</item>

<item>#string/hr2</item>
</string-array>
<string-array name="array2">
<item>#string/min5</item>
<item>#string/min10</item>
<item>#string/min15</item>

i want:
1- retrieve the item in spinner that the user choose it, not the positon
2-if the user choose from spinner1 the item "hr02" then the spinner2 will disable
Thank you for help me, StackOverFlow members your my hero now! :")

use this
String str = parent.getSelectedItem().toString();
if(str.equals("hr2")
{
spinner2.setEnabled(false);
}

Try this:
String str = parent.getSelectedItem().toString();
if (str.equals("hr0")){
//retrieve the item as string
}
if (str.equals("hr1")){
//retrieve the item as string
}
if (str.equals("hr2")){
//retrieve the item as string
//make the 2nd spinner disable
}
