基于安卓的云同步记事本使用Bmob遇到的空指针问题
protected void inni(){
BmobQuery<Note> bmobQuery = new BmobQuery<Note>();
bmobQuery.addQueryKeys("id");
bmobQuery.findObjects(new FindListener<Note>() {
String s1 = null;
String s2 = null;
long id1 = 0;
int in1 = 0;
@Override
public void done(List<Note> object, BmobException e) {
Log.d("tess","1111");
if(e==null){
Log.d("tess","2222");
int n = Objects.requireNonNull(object.size());
for(int i = 0; i < n; i++){
id1 = Objects.requireNonNull(object.get(i).getId());
s1 = Objects.requireNonNull(object.get(i).getContent());
s2 = Objects.requireNonNull(object.get(i).getTime());
in1 = Objects.requireNonNull(object.get(i).getTag());
Note newNote = new Note(s1, s2, in1, id1);
CRUD op = new CRUD(context);
op.open();
op.addNote(newNote);
op.close();
}
}else{
Log.d("bmob1","失败："+e.getMessage()+","+e.getErrorCode());
}
}
});
refreshListView();
}
