我尝试cancel transaction Realm RealmRecyclerView Snackbar内undo，{@ 1}}项目被删除后，会出现asynchronous transactions ，使track请求成为可能。当我发出多个删除请求时，会抛出异常。我正在阅读public void deleteItem(View view, int position) {
if (getData() != null && getData().getPosition(position).isValid()) {
MyObjectRealm item = getData().getPosition(position);
realm.beginTransaction();
item.deleteFromRealm();
notifyItemRemoved(position);
showSnackbar(view, position);
}
}
private void showSnackbar(View view, int position) {
Snackbar snackbar = Snackbar.make(view, context.getString(R.string.removed), Snackbar.LENGHT_SHORT);
snackbar.setAction(context.getString(R.string.undo), new View.OnClickListener() {
@Override
public void onClick(View view) {
if (realm.isInTransaction()) {
realm.cancelTransaction();
notifyItemRangeChanged(position, getItemCount());
}
}
});
snackbar.addCallback(new Snackbar.Callback() {
@Override
public void onDismissed(Snackbar transientBottomBar, int event) {
if(realm.isInTransaction()) {
realm.commitTransaction();
}
}
});
snackbar.show();
}
