[android-developers] Re: Simple Cursor Adapter - List View
Hi,
You might find useful to set a ViewBinder for the adapter.
Have a look at this interface for the SimpleCursorAdapter
http://developer.android.com/reference/android/widget/SimpleCursorAdapter.ViewBinder.html
There's only one method which is invoked for each column-to-view bind
and it gives you the cursor and the column index so you can easily
retrieve the value of a column and based on that evaluate if you want
to make the view visible or not by setting the visibility invoking the
method setVisibility().
Cheers,

I have table with 3 columns which is binded to an XML document with

String[] from = new String[]{A,B,C};
int [] to = new int[] {R.id.a,R.id.b,R.id.c};
Where R.id.a, R.id.b, R.id.c - TextView
Depending on the value store in the third column, I have to decide
whether i should display this row or not
How should, I go about with this.
This is what I have so far :
SimpleCursorAdapterentry = newSimpleCursorAdapter(this,
R.layout.addrow, vCursor , from , to);
setListAdapter(entry);
If you can provide me an example, that would be really helpful.

[android-developers] Re: Simple Cursor Adapter - List View
You should create your own adapter (probably derived from
SimpleCursorAdapter) that does this in its bindView method.

[android-developers] Re: Simple Cursor Adapter - List View
Here is an example of the the simplest way I have found to do this
type of thing.
public class IconCursorAdapter extends SimpleCursorAdapter {
IconCursorAdapter(Context context, int layout, Cursor cursor,String[]
from, int[] to) {
super(context, layout, cursor, from, to);
this.setViewBinder(new IconViewBinder());
}
}
public class IconViewBinder implements SimpleCursorAdapter.ViewBinder
{
public boolean setViewValue(View view, Cursor cursor, int
columnIndex) {
if (view instanceof TextView) {
((TextView)
view).setText(cursor.getString(columnIndex));
return true;
}
if (view instanceof ImageView) {
String listType = cursor.getString(columnIndex);
if (listType.equals(wish_list)) {
((ImageView)
view).setImageResource(R.drawable.lander_plain);
return true;
}
if (listType.equals(todo_list)) {
((ImageView)
view).setImageResource(R.drawable.lander_firing);
} else {
((ImageView)
view).setImageResource(R.drawable.lander_crashed);
}
return true;
}
return false;
}
}
