我试图从Parse Class中删除对象，其中requesterUsername等于当前用户名。我在Parse数据库中有超过7行数据，但是当我执行下面的方法时， public void requestGride(View view){
if(requestActive == false) {
Log.i("MyApp", "Gride requested");
ParseObject request = new ParseObject("Requests");
request.put("requesterUsername", ParseUser.getCurrentUser().getUsername());
ParseACL parseACL = new ParseACL();
parseACL.setPublicWriteAccess(true);
request.setACL(parseACL);
request.saveInBackground(new SaveCallback() {
@Override
public void done(ParseException e) {
if (e == null) {
infoTextView.setText("Finding Gride..");
grideX.setText("Cancel GrideX");
requestActive = true;
}
}
});
}else{
infoTextView.setText("GrideX Cancelled");
grideX.setText("GrideX");
requestActive = false;
ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("Requests");
query.whereEqualTo("requesterUsername",ParseUser.getCurrentUser().getUsername());
query.findInBackground(new FindCallback<ParseObject>() {
@Override
public void done(List<ParseObject> objects, ParseException e) {
if(e == null){
if(objects.size() > 0){
for (ParseObject adds : objects){
adds.deleteInBackground();
}
}
}
}
});
}
}
返回0，这不是我的预期，它不会删除数据库中的任何行。
我在这里一无所知。任何帮助将不胜感激。提前谢谢。
