setSelection on Spinner based on rowId

Question

I have a Spinner View that\'s populated through a SimpleCursorAdapter.

Based on the selection I need to save the rowid in the entry database (posit

Answer 1

I agree with Erich Douglass's above answer but i found fastest loop syntax which will be useful while spinner.getCount() is greater than 50k to 100k.

/* 1 (fastest) */
for (int i = initializer; i >= 0; i--) { ... }

/* 2 */
int limit = calculateLoopLimit();
for (int i = 0; i < limit; i++) { ... }

/* 3 */
Type[] array = getMyArray();
for (Type obj : array) { ... }

/* 4 */
for (int i = 0; i < array.length; i++) { ... }

/* 5 */
for (int i = 0; i < this.var; i++) { ... }

/* 6 */
for (int i = 0; i < obj.size(); i++) { ... }

/* 7 (slowest) */
Iterable list = getMyList();
for (Type obj : list) { ... }

So i think we can use here second for better performance:

int spinnerCount = spinner.getCount();
for (int i = 0; i < spinnerCount; i++) {
    Cursor value = (Cursor) spinner.getItemAtPosition(i);
    long id = value.getLong(value.getColumnIndex("_id"));
    if (id == rowid) {
        spinner.setSelection(i);
    }
}
