ListView Android crashes with Runtime exception

Question

My List view seems to be crashing no matter what I do. Here is the code that passes a Bundle to a List handling activity NotificationList

Bundle extras= new Bundle();
Intent  intent= new Intent(Locations.this, NotificationList.class);
extras.putString("name0", "Robowars");
extras.putString("name1", "Robowa");

extras.putString("time0", "1:40");
extras.putString("time1", "1:30");

extras.putString("place0", "ekm");
extras.putString("place1", "ekm2");

extras.putString("id0","my id");
extras.putString("id1", "new id");

extras.putString("type0", "tech");
extras.putString("type1", "cult");

extras.putString("count", "1");
intent.putExtras(extras);
startActivity(intent);

And here is the code for my NotificationList:

public class NotificationList extends ActionBarActivity {

String listName[],listPlace[],listTime[],listId[],listType[];
ListView listview;
String count;


Intent intent;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub

    super.onCreate(savedInstanceState);
    setContentView(R.layout.culturallist);

    intent= getIntent();

      //  TypedArray listThumbnail;
        listview = (ListView) findViewById(R.id.list);


    count=intent.getExtras().getString("count");
    int n=Integer.parseInt(count);
    for (int  i=0;i<=n;++i)
    {
        listName[i]= intent.getExtras().getString("name"+String.valueOf(i));
        listPlace[i]=intent.getExtras().getString("place"+String.valueOf(i));
        listTime[i]=intent.getExtras().getString("time"+String.valueOf(i));    
        listId[i]=intent.getExtras().getString("id"+i);
        listType[i]=intent.getExtras().getString("type"+String.valueOf(i));

    //    Toast.makeText(NotificationList.this, listName[i], Toast.LENGTH_LONG).show();
    }

    listview.setAdapter(new NotifListAdapter(NotificationList.this,listName,listPlace,listTime,listType,listId));


    /*AsyncList list= new AsyncList();
    list.execute();*/

      listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int j, long l) {


            Intent intent= new Intent(NotificationList.this,CardActivity.class);
                Bundle extras= new Bundle();

                String id = ((TextView)findViewById(R.id.id)).toString();
                String type = ((TextView) findViewById(R.id.eventtype)).toString();

                extras.putString("key", id);
        extras.putString("eventtype", type);

                intent.putExtras(extras);
                startActivity(intent);
            }
        });
    }

}

And here is the custom adapter:

    class NotifFonts{
    private static Typeface typeFace;

    public static Typeface getTypeFace(Context mContext){

            if(typeFace==null)
            {
                typeFace = Typeface.createFromAsset(mContext.getAssets(), "fonts/robotolight.ttf");
            }

        return typeFace;
    }
}

class NotifListAdapter extends BaseAdapter {

    static class ViewHolder{
        TextView title,place,time,id,type;

    }

    private String[] listName,listId,listType,listPlace,listTime;

    private  Context context;

    private static LayoutInflater inflater = null;

    public NotifListAdapter(Context context,
            String[] listName, String[] listPlace, String[] listTime,
            String[] listType, String[] listId) {


        this.listId=listId;
        this.listName=listName;
        this.listPlace=listPlace;
        this.listTime=listTime;
        this.listType=listType;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return listName.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return listName[position];
    }


    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View vi, ViewGroup parent) {

        ViewHolder holder;
        if (vi == null) 

        {
            holder=new ViewHolder();
            vi = inflater.inflate(R.layout.list_row_notif,null);
         holder.title = (TextView) vi.findViewById(R.id.name); 
         holder.place=(TextView) vi.findViewById(R.id.place); 
         holder.time=(TextView) vi.findViewById(R.id.time); 
         holder.id=(TextView) vi.findViewById(R.id.id);
         holder.type=(TextView) vi.findViewById(R.id.eventtype);
    //     holder.thumbnail=(ImageView) vi.findViewById(R.id.list_image);  
            vi.setTag(holder);
        }
        else
        {
            holder=(ViewHolder) vi.getTag();
        }


     try {
        holder.title.setTypeface(NotifFonts.getTypeFace(context));
         holder.place.setTypeface(NotifFonts.getTypeFace(context));

     holder.title.setText(listName[position]);    
          //  holder.thumbnail.setImageResource(listThumbnail.getResourceId(position, -1));
     holder.time.setText(listTime[position]);
     holder.place.setText(listPlace[position]);
     holder.id.setText(listId[position]);
     holder.type.setText(listType[position]);
    } catch (Exception e) {

        e.printStackTrace();
    }

        return vi;
    }
}

It's crashing due to NPE and the logcat should tell you the specific line in the file. — Robby Pond, Sep 23 '13 at 17:35
Try to debug it, I'm pretty sure it is in your loop where you do the "intent.getExtras().getString("name"+String.valueOf(i));" thing. Post the full logcat output though, nobody wants to wildly guess what it could be when we can just look at the exact line instead. — bgse, Sep 23 '13 at 17:48
`String id = ((TextView)findViewById(R.id.id)).toString();` getting NPE here? post Line no 48 `NotificationList.java`? — Raghunandan, Sep 23 '13 at 17:54
No, I tried disabling the list onItemClick, still doesn't work. Also tried using "name0", "place0" etc. directly instead of using the for-loop to get the bundle strings — user2808187, Sep 23 '13 at 17:56
int i=0; listName[i]= intent.getExtras().getString("name0"); listPlace[i]=intent.getExtras().getString("place0"); listTime[i]=intent.getExtras().getString("time0"); listId[i]=intent.getExtras().getString("id0"); listType[i]=intent.getExtras().getString("type0"); — user2808187, Sep 23 '13 at 17:57
You got NPE at `NotificationList.java:48` try checking that line. — Ariel Magbanua, Sep 23 '13 at 17:58
This is line 48 : listName[i]= intent.getExtras().getString("name0") — user2808187, Sep 23 '13 at 17:59
@user2808187 then check how you use putExtras and getExtras. keys must match. try using "name0". — Raghunandan, Sep 23 '13 at 18:00
Oh did you passed data from the previous activity of NotificationList activity? — Ariel Magbanua, Sep 23 '13 at 18:04
yes, check the first block of code I pasted above, it is the Bundle passing code — user2808187, Sep 23 '13 at 18:05
This means that you didn't put any extras in your previous activity that started the notification list, and String with the key "name0" is definitely a null. — Ariel Magbanua, Sep 23 '13 at 18:06
Arman, please refer to my first block of code in the question — user2808187, Sep 23 '13 at 18:07
@user2808187 - verify that the Intent *has* extras before you try to use them. Making sure you put them in the intent you create is important, but consider that your Activity might eventually receive an Intent from some other source and add the checking / graceful failure. — Chris Stratton, Sep 23 '13 at 18:09
I posted an answer, one is intent way of passing data and the other using Bundles. — Ariel Magbanua, Sep 23 '13 at 18:13

if i am not wrong then you have not initialize your string arrays

please initialize your string[] as

int n=Integer.parseInt(count);
listname=new String[n];
listplace=new String[n];

and so on for all arrays

for (int  i=0;i<=n;++i)
{
....

Your activity cannot be started/initialised, that is what your Logcat is saying. Therefore, I would make sure that every single Activity is defined in the Manifest.xml as that could be your root cause.

What about changing protected void onCreate() to public void onCreate()

Try this one,

Intent  intent= new Intent(Locations.this, NotificationList.class);
intent.putString("name0", "Robowars");
intent.putString("name1", "Robowa");

intent.putString("time0", "1:40");
intent.putString("time1", "1:30");

intent.putString("place0", "ekm");
intent.putString("place1", "ekm2");

intent.putString("id0","my id");
intent.putString("id1", "new id");

intent.putString("type0", "tech");
intent.putString("type1", "cult");

intent.putString("count", "1");

startActivity(intent);

If you really want to use Bundle to pass data. Read the thread below it will help you.

Passing a Bundle on startActivity()?
