hi,
the favicon field returned by the browser bookmark provider is a
sqlite blob.
I want to display the bookmarks in a listview with the favicon but
couldn't find a way to do it.
I tried using a SimpleCursorAdapter.ViewBinder but I get an exception.
this is what my code looks like :
Cursor bookmarks;
String[] proj = new String[] {
android.provider.Browser.BookmarkColumns.URL,
android.provider.Browser.BookmarkColumns.TITLE,
android.provider.Browser.BookmarkColumns.FAVICON
};
bookmarks = managedQuery(android.provider.Browser.BOOKMARKS_URI,
proj, null, null, android.provider.Browser.BookmarkColumns.URL + "
ASC");
SimpleCursorAdapter adapter = new SimpleCursorAdapter(
this,
R.layout.bookmark_element,
bookmarks,
new String[]
{android.provider.Browser.BookmarkColumns.URL,
android.provider.Browser.BookmarkColumns.TITLE,
android.provider.Browser.BookmarkColumns.FAVICON},
new int[] { R.id.url,R.id.titre, R.id.icon});
adapter.setViewBinder(new BookmarkDataViewBinder());
setListAdapter(adapter);
and this is my viewbinder class :
class BookmarkDataViewBinder implements SimpleCursorAdapter.ViewBinder
{
@Override
public boolean setViewValue(View view, Cursor cursor, int
columnIndex) {
if(view.getClass().getName().equals("android.widget.ImageView")) {
byte[] b = cursor.getBlob(columnIndex);
if(b != null) {
Bitmap bitmap =
BitmapFactory.decodeByteArray(b, 0, b.length);
((ImageView)view).setImageBitmap(bitmap);
}
else {
((ImageView)view).setImageResource(R.drawable.icon);
}
return true;
}
return false;
}
}
if the favicon blob field is null, the viewbinder does its job and it
displays the default icon. but if it is not null, this is the
exception I get :
E/AndroidRuntime( 1365): Uncaught handler: thread main exiting due to

according to my logs, the exception occurs before my viewbinder is
called.
can somebody help?
thanks
