I'm using CommonsGuy's drag n drop example and I am basically trying to integrate it with the Android notepad example.
Out of the 2 different drag n drop examples i've seen they have all used a static string array where as i'm getting a list from a database and using simple cursor adapter.
So my question is how to get the results from simple cursor adapter into a string array, but still have it return the row id when the list item is clicked so I can pass it to the new activity that edits the note.
Here is my code:
Cursor notesCursor = mDbHelper.fetchAllNotes();
startManagingCursor(notesCursor);
// Create an array to specify the fields we want to display in the list (only NAME)
String[] from = new String[]{WeightsDatabase.KEY_NAME};
// and an array of the fields we want to bind those fields to (in this case just text1)
int[] to = new int[]{R.id.weightrows};
// Now create a simple cursor adapter and set it to display
SimpleCursorAdapter notes =
new SimpleCursorAdapter(this, R.layout.weights_row, notesCursor, from, to);
setListAdapter(notes);
And here is the code i'm trying to work that into.
public class TouchListViewDemo extends ListActivity {
private static String[] items={"lorem", "ipsum", "dolor", "sit", "amet",
"consectetuer", "adipiscing", "elit", "morbi", "vel",
"ligula", "vitae", "arcu", "aliquet", "mollis",
"etiam", "vel", "erat", "placerat", "ante",
"porttitor", "sodales", "pellentesque", "augue", "purus"};
private IconicAdapter adapter=null;
private ArrayList<String> array=new ArrayList<String>(Arrays.asList(items));
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
adapter=new IconicAdapter();
setListAdapter(adapter);
TouchListView tlv=(TouchListView)getListView();
tlv.setDropListener(onDrop);
tlv.setRemoveListener(onRemove);
}
private TouchListView.DropListener onDrop=new TouchListView.DropListener() {
@Override
public void drop(int from, int to) {
String item=adapter.getItem(from);
adapter.remove(item);
adapter.insert(item, to);
}
};
private TouchListView.RemoveListener onRemove=new TouchListView.RemoveListener() {
@Override
public void remove(int which) {
adapter.remove(adapter.getItem(which));
}
};
class IconicAdapter extends ArrayAdapter<String> {
IconicAdapter() {
super(TouchListViewDemo.this, R.layout.row2, array);
}
public View getView(int position, View convertView,
ViewGroup parent) {
View row=convertView;
if (row==null) {
LayoutInflater inflater=getLayoutInflater();
row=inflater.inflate(R.layout.row2, parent, false);
}
TextView label=(TextView)row.findViewById(R.id.label);
label.setText(array.get(position));
return(row);
}
}
}
I know i'm asking for a lot, but a point in the right direction would help quite a bit! Thanks
