How to pass data collected in arraylist from json asset file in one activity having recyclerview to another activity again having recycler view?

I have an activity named Cardview Activity which has a recycler view associated with it and i am fetching data from a JSON asset file in that. But now when i click on an item of Cardview Activity, I want to send data related to that item only to another activity i.e. People_List_Activity which is again having a recyclerView.

how can i send the Person_Id, Name and Designation to the People_List_Activity ? Please help as i am stuck in the code.

You can send using Intent , by passing your data in Bundle and then pass Bundle into Intent Extras.When you go form one Activity to another .
Intent intent=new Intent(CardViewActivity.this,PeopleListActivity.class);
Bundle bundle = new Bundle();
bundle.putString("key1",value1);
bundle.putString("key2",value2);
bundle.putString("key3",value3);
intent.putExtras(bundle)
startActvity(intent);
And You can retrieve Data in next Activity OnCreate():
Bundle bundle = getIntent().getExtras();
String value1 = bundle.getString("key1");
String value2 = bundle.getString("key2");
String value3 = bundle.getString("key3");

Using a class (DatePicker) insider a fragment on Android

I am trying to fetch the value of a Datepicker inside one of my fragments . I've read the documentation about Fragments in the Android Developer Guide.
Here is my Fragment layout :
<ir.smartlab.persindatepicker.PersianDatePicker
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:id="#+id/btnCheckFal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/relativeLayout1"
android:layout_centerHorizontal="true"
android:layout_marginTop="19dp"
android:text="#string/CheckFal" />
</RelativeLayout>
This is my java class for the fragment :
import ir.smartlab.persindatepicker.util.PersianCalendar;
public class HomeFragment extends Fragment {

private PersianDatePicker persianDatePicker;

btnCheckFalAction = (Button) rootView.findViewById(R.id.btnCheckFal);
PersianCalendar pCal = persianDatePicker.getDisplayPersianDate();
btnCheckFalAction.setOnClickListener(new OnClickListener() {
#Override

{
Toast.makeText(getActivity(), "Date is : " + pCal , Toast.LENGTH_LONG).show();

It's simple.
Make pCal final, if you don't have to change its value during execution.
OR
Make pCal a class variable if you don't have any problems with a wider scope.

Declare pCal variable as final and initialise persianDatePicker view using findViewById().
You can change the code like this,
btnCheckFalAction = (Button) rootView.findViewById(R.id.btnCheckFal);
persianDatePicker = (PersianDatePicker) rootView.findViewById(R.id.persianDatePicker);
PersianCalendar pCal = persianDatePicker.getDisplayPersianDate();
and also edit your xml like this,
<ir.smartlab.persindatepicker.PersianDatePicker
android:id="#+id/persianDatePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

How to solve error loading KeypressDelete.ogg, KeypressReturn.ogg?

I am learning Android from one of the examples in a book (Android Programming - The Big Nerd Ranch Guide) and I am following their code verbatim. Very simple code, well at least I thought...Below is the image of my emulator and most, if not all the code, with the exception of the layout files.
My emulator is using API Level 18 android 4.3.1 cpu ARM. When I click on a crime from the list, I am suppose to see a log stating I clicked on crime #x but I don't see it. Instead I see SoundPool tag with error loading /system/media/audio/ui/KeypressDelete.ogg and 4 other similar errors like error loading KeypressReturn.ogg.
I scoured the internet and on stack overflow for a solution for hours. All I can find is "ignore it" or "turn off the settings", which I don't know how but I don't want to turn it off. I want to solve it and move on with this example so I can learn. Would anyone know of this error and can help me solve it, please? I appreciate it.
Here are part of the code:
public class Crime
{
private UUID mId;
private String mTitle;
private Date mDate;
private boolean mSolved;
public Crime()
{
// Generate unique identifier
mId = UUID.randomUUID();
mDate = new Date();
}
public String getTitle()
{
return mTitle;
}
public void setTitle(String title)
{
mTitle = title;
}
public UUID getId()
{
return mId;
}
public Date getDate()
{
return mDate;
}
public void setDate(Date date)
{
mDate = date;
}
public boolean isSolved()
{
return mSolved;
}
public void setSolved(boolean solved)
{
mSolved = solved;
}
#Override
public String toString()
{
return mTitle;
}
}
public class CrimeLab
{
private ArrayList<Crime> mCrimes;
private static CrimeLab sCrimeLab;

mCrimes = new ArrayList<Crime>();
// Mock Crime objects
for (int i = 0; i < 100; i++)
{
Crime c = new Crime();
c.setTitle("Crime #" + i);
c.setSolved(i % 2 == 0); // Every other one
mCrimes.add(c);
}
}
public static CrimeLab get(Context c)
{
if (sCrimeLab == null)
{
sCrimeLab = new CrimeLab(c.getApplicationContext());
}
return sCrimeLab;
}
public ArrayList<Crime> getCrimes()
{
return mCrimes;
}
public Crime getCrime(UUID id)
{
for (Crime c : mCrimes)
{
if (c.getId().equals(id))
return c;
}
return null;
}

What's wrong? How can I fix it? I'm using IntelliJ IDEA 12 CE. Thanks a lot for any help!

This can be resolved by recreating the R.java file.
1. Re-build OR
2. Change the 'android:id' in XML file to a new id and re-build. Make sure you manually change all references to this id.

Sometimes this does´t work even recreating the R.java file, cleaning and rebuilding the project.
for me it works until i delete \gen and \bin folders, then automatically were recreated with the new relationship between resources and their id´s.

I think the problem is just that the inflater cast your item to RelativeLayout and you can't cast a relativeLayout in your item (Maybe this post is more precise : ClassCastException). Perhaps you have to give up and retrieve your object using your id with findViewById.
