Views disappears after a time from Listview

Question

Hi in my project i am using an custom adapter. When the activity which contains listview opened, image views and text views appears at first and after a time views dissappears.I couldnt find a solution do u have any idea? edit: Also it works on emulator but dont work on normal device?

The class where i set adapter:

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_person_deatil);
    Intent detailIntent = getIntent();
    Gson gson = new Gson();
    String obj = detailIntent.getStringExtra("obj");
    PeopleListItem people = gson.fromJson(obj, PeopleListItem.class);

    ListView lw = (ListView) findViewById(R.id.perdetLw);

    PeopleListItem[] list = new PeopleListItem[6];
        for(int i=0; i<6; i++){
            list[i] = people;
        }

    ActionBar ab = getActionBar();
    ab.setDisplayHomeAsUpEnabled(true);
    ab.setTitle(people.getName());
    ab.setIcon(R.drawable.ic_action_person);

    PeopleDetailArrayAdapter adp = new PeopleDetailArrayAdapter(this, R.layout.person_detail_item, list);
    lw.setAdapter(adp);

} 

The class of custom Adapter:

  public class PeopleDetailArrayAdapter extends ArrayAdapter<PeopleListItem> {

int resource;
Context context;
int count = 0;
public PeopleDetailArrayAdapter(Context context, int resource,
        PeopleListItem[] list) {
    super(context, resource, list);
    this.resource = resource; 
    this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub

    final PeopleListItem peopleObj = getItem(position);
    LayoutInflater layoutInflator = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View listViewItem = layoutInflator.inflate(resource, null);

    final TextView textView = (TextView) listViewItem.findViewById(R.id.detailTw);
    final TextView textView1 = (TextView) listViewItem.findViewById(R.id.detailTw1);
    final ImageView imageView = (ImageView) listViewItem.findViewById(R.id.detailIw);//img view kişinin resmine göre değişmeli
    final ImageView imageView1 = (ImageView) listViewItem.findViewById(R.id.detailIw1);

    switch (count) {
    case 0:
        textView.setText("Title:");
        String title = peopleObj.getTitle();
        textView1.setText(title);
        break;
    case 1:
        textView.setText("Department:");
        String dep = peopleObj.getDepart();
        textView1.setText(dep);
        break;  
    case 2:
        textView.setText("Work Phone:");
        String wp = peopleObj.getWorkPhone();
        textView1.setText(wp);
        imageView.setVisibility(ImageView.VISIBLE);
        break;
    case 3:
        textView.setText("Mobile Phone:");
        String mp = peopleObj.getMobilePhone();
        textView1.setText(mp);
        imageView.setVisibility(ImageView.VISIBLE);
        imageView1.setVisibility(ImageView.VISIBLE);
        break;
    case 4:
        textView.setText("Email:");
        String email = peopleObj.getEmail();
        textView1.setText(email);
        break;
    case 5:
        textView.setText("Manager:");
        String man = peopleObj.getManager();
        textView1.setText(man);
        break;
    default:
        break;
    }
    count++;
    return listViewItem;
}

}  

Answer 1

i solved problem by using position instead of using count

          public class PeopleDetailArrayAdapter extends ArrayAdapter<PeopleListItem> {

int resource;
Context context;

public PeopleDetailArrayAdapter(Context context, int resource,
        PeopleListItem[] list) {
    super(context, resource, list);
    this.resource = resource; 
    this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub

    final PeopleListItem peopleObj = getItem(position);
    LayoutInflater layoutInflator = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View listViewItem = layoutInflator.inflate(resource, null);

    final TextView textView = (TextView) listViewItem.findViewById(R.id.detailTw);
    final TextView textView1 = (TextView) listViewItem.findViewById(R.id.detailTw1);

    switch (position) {
    case 0:
        textView.setText("Title");
        String title = peopleObj.getTitle();
        textView1.setText(title);
        break;
    case 1:
        textView.setText("Department");
        String dep = peopleObj.getDepart();
        textView1.setText(dep);
        break;  
    case 2:
        textView.setText("Work");
        String wp = peopleObj.getWorkPhone();
        textView1.setText(wp);
        break;
    case 3:
        textView.setText("Mobile");
        String mp = peopleObj.getMobilePhone();
        textView1.setText(mp);
        break;
    case 4:
        textView.setText("Email");
        String email = peopleObj.getEmail();
        textView1.setText(email);
        break;
    case 5:
        textView.setText("Manager");
        String man = peopleObj.getManager();
        textView1.setText(man);
        break;
    }

    return listViewItem;
}

}
