I am trying to populate a list list with an ImageView
, and three TextViews from an SQLite database. The data in the TextView
s is what i expect it to be, but the ImageView
never changes.
The ImageView
is supposed to swap between two icons depending on the value of the Cursor at x row in y column. The column is populated with an Integer
of 1
or 0
. If column y @ row x is 1 the red image should populate the ImageView
. If 0 then the green image should.
That never seems to happen. It is always the red image, and the logcat always says the the value of cursor is 1.

Here is a snippet of the SQLite database.
_id, weight, height, body_mass_index, icon, date
"1","45.359233334609435","1778.003556007112","14.348300215310468","0","2015-04-14"
"2","47.627195001339906","1778.003556007112","15.06571522607599","1","2015-04-14"
"3","45.359233334609435","1778.003556007112","14.348300215310468","0","2015-04-14"
As you can see the icon should have been green then red and then green, but it was just red all three times. I really would appreciate some help with figuring out why my code doesn't work. Here is my bindView
.
@Override
public void bindView(View view, Context context, Cursor cursor) {
ImageView iconView = (ImageView) view.findViewById(R.id.richListIcon);
TextView weightInfo = (TextView) view.findViewById(R.id.personal_item1);
TextView bmiInfo = (TextView) view.findViewById(R.id.personal_item2);
TextView dateInfo = (TextView) view.findViewById(R.id.timestamp_item);
int indexWeight;
int indexBmi;
int indexDate;
String weightHolder = null;
String weightModified = null;
String bmiHolder = null;
String bmiModified = null;
String dateHolder = null;
String upDateHolder = null;
int iconHolder = 3;
int iconSet;
if (cursor != null) {
Log.wtf(String.valueOf(getActivity()), "not null");
iconHolder = (cursor.getColumnIndex
(DatabaseAdapter.DataManager.publicIconSetter));
Log.d("cursor@iconHolder", String.valueOf(cursor.getColumnIndexOrThrow
(DatabaseAdapter.DataManager.publicIconSetter)));
weightHolder = (String.valueOf
(cursor.getDouble(cursor.getColumnIndex
(DatabaseAdapter.DataManager.publicWeight))));
bmiHolder = (String.valueOf
(cursor.getDouble(cursor.getColumnIndex
(DatabaseAdapter.DataManager.publicBMI))));
dateHolder = (String.valueOf
(cursor.getString(cursor.getColumnIndex
(DatabaseAdapter.DataManager.publicDate))));
}
switch (iconHolder){
case 0:
iconSet = R.mipmap.green_icon;
Log.d("icon", "false " + iconHolder);
break;
case 1:
Log.d("icon", "true " + iconHolder);
iconSet = R.mipmap.red_icon;
break;
default: iconSet = R.mipmap.ic_launcher;
Log.wtf("IVF_IconSetter", "Error, value from table is " + iconHolder);
}
iconView.setImageResource(iconSet);
...
}
And my Crusor
public Cursor getAllData(){
SQLiteDatabase database = dataManager.getReadableDatabase();
String[] columns = {DataManager.UID,
DataManager.Icon_Gained_Weight,
DataManager.Weight,
DataManager.BMI,
DataManager.Date
};
String orderBy = DataManager.UID + " DESC";
Cursor cursor = null;
try {
cursor = database.query(DataManager.TABLE_NAME, columns, null, null, null, null, orderBy);
if(cursor != null){
cursor.moveToFirst();
}
} catch (IllegalArgumentException e) {
e.printStackTrace();
}
return cursor;
}
This problem has been solved by Playmaker420. I'll write out the answer if Playmaker420 chooses not to do so.
System.out.println(cursor.getString(cursor.getColumnIndex("icon"));
This should print the value of the column "icon"
