遍历一组Android复选框Android

Question

我有一组android复选框。在我的Java代码中，我创建了checkbox数组，然后使用for循环遍历该数组，在循环之后，我随后切换了每个复选框值的值，在每种情况下，我都想向sqlite数据库插入一些值。当我选择多个复选框时，仅将数组中的最后一个复选框值插入数据库：

1. ArrayList<String> selectedSubjectsList = new ArrayList<String>();
   

2. CheckBox[] subjectBoxes = {A, B}
   

3. for (CheckBox cb : subjectBoxes) {
       if (cb.isChecked()) {
           selectedSubjectsList.add((String) cb.getText());
       }
   }
   Object[] subObj = selectedSubjectsList.toArray();
   String[] selectedSubjectsListArray = Arrays.copyOf(subObj, 
   subObj.length, String[].class);
   

4. for (String s : selectedSubjectsListArray) {
       switch (s) {
           case "A_valu":
               String table_name = "A_table";
               swich_Subject("path_downloding_A","Chemistry");
               break;
   
           case "B_value":
               String table_name = "B_table";
               swich_Subject("path_downloding_B", "Physics");
               break;   
           defult:
   } 
   

5. public void LoadQuestion_linkTodatabase(SQLiteDatabase db, ContentValues cv) {
       db.insert(table_name, null, cv);
   }
   

6. public void swich_Subject(final String pathFrom, final String DownlodOk) {
       final FirebaseDatabase database = FirebaseDatabase.getInstance();
       DatabaseReference myRef = database.getReference(pathFrom);
       myRef.addListenerForSingleValueEvent(new ValueEventListener() {
           @Override
           public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
               SQLiteDatabase db = con.getWritableDatabase();
               db.delete(table_name, "1", null);
               //String topic="";
               for (DataSnapshot dsp : dataSnapshot.getChildren()) {
                   String topic = dsp.getKey();
                   for (DataSnapshot dspinner : dsp.getChildren()) {
                       String A, B = "";
                       A =dspinner.child("A").getValue().toString();
                       B = dspinner.child("B").getValue().toString();
   
                       //Block of code that will insert data into my local database storage
   
                       ContentValues InsertUsersInfo = new ContentValues();
                       InsertUsersInfo.put("topics_A", A);
                       InsertUsersInfo.put("question_B", B);
                       LoadQuestion_linkTodatabase(mydb, InsertUsersInfo);
                   }
               }
           }
   
           @Override
           public void onCancelled(@NonNull DatabaseError databaseError) {
               Toast.makeText(ctx, databaseError.getMessage(), 
                              Toast.LENGTH_SHORT).show();
           }
       });
   }
