これは、BaseAdapter を拡張したカスタム リストビューです。選択したラジオボタンの値を取得する必要がありますが、方法がわかりません。だから私を助けてください。以下は、カスタム アダプター クラスです。

public class CustomArrayAdapter extends BaseAdapter implements OnCheckedChangeListener {
private Context context;
private String[] q,o1,o2,o3,o4;
private int count=0;
private ArrayList<HashMap<String, String>> data ;

public CustomArrayAdapter(Context context, ArrayList<HashMap<String, String>> d) {
    super();
    this.context = context;
    data = d;
    count++;
    System.out.println("adhe padhe nuna chate");
}



public View getView(int position, View convertView, ViewGroup parent){
    LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.custom_questions, parent, false);

     TextView tv = (TextView)rowView.findViewById(R.id.textView1);


    RadioGroup rg = (RadioGroup)rowView.findViewById(R.id.radioGroup1);
    final RadioButton rb1 = (RadioButton)rowView.findViewById(R.id.radio0);
    final RadioButton rb2 = (RadioButton)rowView.findViewById(R.id.radio1);
    final RadioButton rb3 = (RadioButton)rowView.findViewById(R.id.radio2);
    final RadioButton rb4 = (RadioButton)rowView.findViewById(R.id.radio3);

    HashMap<String, String> hMap = new HashMap<String,String>();
    hMap = data.get(position);
    tv.setText(hMap.get("questions"));
    rb1.setText(hMap.get("op1"));
    rb2.setText(hMap.get("op2"));
    rb3.setText(hMap.get("op3"));
    rb4.setText(hMap.get("op4"));



    rg.setOnCheckedChangeListener(this);


    rb1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {


        }
    });

    return rowView;
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return data.size();
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return 0;
}



@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {

}

}

以下は、別のクラスからカスタムアダプターに値を入れる方法です。

    String questions[] = { "what is your name", "why are you here" };
    String op1[] = { "Anil", "Play" };
    String op2[] = { "John", "Sick" };
    String op3[] = { "David", "Write" };
    String op4[] = { "Akshay", "Act" };



    for (int i = 0; i < questions.length; i++) {
        HashMap<String, String> hMap1 = new HashMap<String, String>();
        hMap1.put("questions", questions[i]);
        hMap1.put("op1", op1[i]);
        hMap1.put("op2", op2[i]);
        hMap1.put("op3", op3[i]);
        hMap1.put("op4", op4[i]);

        radioData.add(hMap1);
    }


    /*ListAdapter adapter = new SimpleAdapter(getActivity(), radioData,
            R.layout.custom_questions, new String[] { "questions", "op1",
                    "op2", "op3", "op4" }, new int[] { R.id.textView1,
                    R.id.radio0, R.id.radio1, R.id.radio2, R.id.radio3 });*/

    CustomArrayAdapter adap = new CustomArrayAdapter(getActivity(), radioData);

    lv.setAdapter(adap);

これを試して ：

  rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {

                @Override
                public void onCheckedChanged(RadioGroup group, int checkedId) {
                    // TODO Auto-generated method stub
                    int childCount = group.getChildCount();
                    for (int x = 0; x < childCount; x++) {
                        RadioButton btn = (RadioButton) group.getChildAt(x);

                        if (btn.getId() == checkedId) {

                            System.out.println(btn.getText().toString());


                    }

                }
            });

次のコードを使用します。

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
string item = hMap1.get(checkedId);  //for single item
int count= group.getChildCount();
                    for (int x = 0; x < count; x++) {
                        RadioButton btn = (RadioButton) group.getChildAt(x);

                        if (btn.getId() == checkedId) {

                           array.add(btn.gettext().tostring);    //adding values to array list
}
}
