Android Fragment with viewbinder

Question

What i found was that i needed a ViewBinder not a custom cursor addapter However the issue i'm having is that on each row it doesn't re-determine if it needs to be hidden or not. Its just always keeping it hidden

Edit: We've gotting it to show the images and hide them when needed but they are disheartening when i scroll.

public class HistoryFragment extends Fragment { 

  ListView listTimeline;
  SimpleCursorAdapter adapter;
  TextView txtCreatedAt, txtFertile, txtTemp, txtCervix;
  ImageView imgIntercorse, imgEnergy, imgPregancy, imgMood, imgHeadache, imgPeriod;
  IntentFilter filter;

  static final String[] FROM = { StatusData.KEY_CHARTING_DATE, StatusData.KEY_CHARTING_NOTES, StatusData.KEY_CHARTING_FERTILE, 
                                 StatusData.KEY_CHARTING_TEMPERATURE, StatusData.KEY_CHARTING_PERIOD, StatusData.KEY_CHARTING_INTERCORSE,
                                 StatusData.KEY_CHARTING_MOOD, StatusData.KEY_CHARTING_HEADACHE, StatusData.KEY_CHARTING_TEST, 
                                 StatusData.KEY_CHARTING_ENERGY };
    static final int[] TO = { R.id.txtCreatedAt, R.id.txtNote, R.id.txtFertile, 
                              R.id.txtTemp, R.id.imgPeriod, R.id.imgIntercorse,
                              R.id.imgMood, R.id.imgHeadache, R.id.imgPregancy,

You've got some null variables. If this is an acceptable value, then just check for null values in your if conditions. If it is not, then you need to change the SQLite table that you're pulling this data from. Something like:

CREATE TABLE some_table(_id INTEGER PRIMARY KEY AUTOINCREMENT, some_column TEXT NOT NULL) etc.

With this structure, if an insertion doesn't include a value for this column, then it will fail.
