Can't populate textview from database

Question

You should try to replace your SimpleCursorAdapter with an ArrayAdapter. To do this we would need a few modifications to your code. We need a new class in your application, which I will call PresentItem, an ArrayAdapter for your list, an XML layout for each row in the list, and a method for converting SQLite rows to PresentItems. First out is the new model, PresentItem:

public class PresentItem  {
    private String name, present;
    private int id;

    public PresentItem(int id, String name, String present) {
         // Init 
    }

    // Getters, setters, etc.

}

So, when we now read from your database, we can convert each rows we get from our query to new PresentItems:

public List<PresentItem> getPresentItems(SQLiteDatabase db) {
    Cursor cursor = db.query("julegaveliste2", 
      new String[] {"_id", "person", "gave"}, null, null, null, null, null);

    List<PresentItem> result = new ArrayList<PresentItem>();
    PresentItem item;

    if (cursor != null && cursor.moveToFirst()) {
        int index = cursor.getColumnIndex("_id");
        int id = cursor.getInt(index));

        index = cursor.getColumnIndex("name");
        String name = cursor.getString(index));

        index = cursor.getColumnIndex("present");
        String present = cursor.getString(index);

        item = new PresentItem(id, name, present);
        result.add(item);
    }
    return result;
}

Once we have the PresentItems parsed from the database, we need a way to display them. To display the PresentItems in your app, we need our own ArrayAdapter, which would look something like this:

public class PresentListAdapter extends ArrayAdapter<PresentItem> {
  private Context ctx;
  private List<PresentItem> presentItems;
  public PresentListAdapter(Context ctx, int layoutResourceId, List<PresentItem> presentItems) { 
    super(context, layoutResourceId, presentItems);
    this.ctx = ctx;
    this.presentItems = presentItems;
}

  public View getView(int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
      LayoutInflater inflater = ((Activity) ctx).getLayoutInflater();
      convertView = inflater.inflate(mLayoutResourceId, parent, false);
    }
  PresentItem item = presentItems.get(position);
  ((TextView) convertView.findViewById(R.id.row_id)).setText("" + item.getId());
  ((TextView) convertView.findViewById(R.id.name)).setText(item.getName());
  ((TextView) convertView.findViewById(R.id.present)).setText(item.getPresent());
  return convertView;
}

To use the adapter in your app, do something like this:

public void visListe(SQLiteDatabase db){   
  List<PresentItem> items = getPresentItems(db);
  PresentItemAdapter adapter = new PresentItemAdapter(this, R.layout.presentListItem, items);
  ListView listView = (ListView) findViewById(R.id.listView1);
  listView.setAdapter(adapter);
  listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}

And, as you might notice, our adapter uses presentListItem as its layout, which we define in res/layout/presentListItem.xml as:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="horizontal"
              android:layout_width="match_parent"
              android:layout_height="wrap_content">

    <TextView android:layout_height="wrap_content"
              android:layout_width="wrap_content"
              android:id="@+id/row_id"
            />
    <TextView android:layout_height="wrap_content"
              android:layout_width="wrap_content"
              android:id="@+id/name"
            />    
     <TextView android:layout_height="wrap_content"
              android:layout_width="wrap_content"
              android:id="@+id/present"
            />
</LinearLayout>

I hope I made it clear and beware bugs in the code - I wrote most of it from memory with a few quick Google searches to help me :) Ask if you need anymore help ^^
