如何檢索單選按鈕值的數據並從android中的sqlite中選擇單選按鈕？

Question

private void collect_data() { 
 

 
     //----- collection & validation for is_required 
 
     String the_choice = ""; 
 
     at_leaset_one_checked = false; 
 
     for (RadioButton rb : allRb) { 
 
      if (rb.isChecked()) { 
 
       at_leaset_one_checked = true; 
 
       the_choice = rb.getText().toString(); 
 
      } 
 
     } 
 

 
     if (the_choice.length() > 0) { 
 
      Answers.getInstance().put_answer(textview_q_title.getText().toString(), the_choice); 
 
      Toast.makeText(getActivity(),"Your ques and asn is:" +textview_q_title.getText() +the_choice, Toast.LENGTH_LONG).show(); 
 
     } 
 

 

 
     
 
     } 
 
     q_data = (Question) getArguments().getSerializable("data"); 
 
     ques_type = (q_data.getQuestionType()); 
 
     ques = textview_q_title.getText().toString(); 
 
     ans = the_choice; 
 
     DbHelper db = new DbHelper(getActivity()); 
 
     if(db.QuesdescExist(ques)) 
 
     { 
 

 
      db.updatedata(ques,ans); 
 
     } 
 
     else { 
 
      db.insertdata(,ques_type ,ques, ans, date, status); 
 
     } 
 

 

 
    } 
 

 

 
    @Override 
 
    public void onActivityCreated(Bundle savedInstanceState) { 
 
     super.onActivityCreated(savedInstanceState); 
 

 

 
     mContext = getActivity(); 
 
     q_data = (Question) getArguments().getSerializable("data"); 
 

 
     textview_q_title.setText(q_data.getQuestionTitle()); 
 

 

 
     List<String> qq_data = q_data.getChoices(); 
 
     if (q_data.getRandomChoices()) { 
 
      Collections.shuffle(qq_data); 
 
     } 
 

 
     for (String choice : qq_data) { 
 
      RadioButton rb = new RadioButton(mContext); 
 
      rb.setText(Html.fromHtml(choice)); 
 
      rb.setTextSize(TypedValue.COMPLEX_UNIT_SP, 16); 
 
      rb.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 
 
      radioGroup.addView(rb); 
 
      allRb.add(rb); 
 

 
      rb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
 
       @Override 
 
       public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
 
        collect_data(); 
 
       } 
 
      }); 
 
     } 
 

 
    

我存儲問題的數據在數據庫中的單選按鈕被點擊的答案，但是當我去到另一個活動我想要回去問這個問題應該有它的回答點擊。請任何人都可以幫助我。

預先感謝您
