如何在片段

Question

如何在Fragment中保存动态生成的radiobutton的状态？当我从一个视图移动到另一个视图时，我将丢失在先前视图中选择的值。提前致谢

以下是我的工作代码：

LayoutFragment.java

public class LayoutFragment extends Fragment {
    int fragVal;
    private String[] application = { "Country1", "Country2", "Country3", "Country4", "Country5", "Country6", "Country7", "Country8" };                     
    private String[] device = { "Country9", "Country10", "Country11", "Country12", "Country13", "Country14", "Country15", "Country16" }; 
    private RadioGroup radioGroup1;
    private RadioGroup radioGroup2;
    private RadioButton btn;
    private RadioButton btn2;
    private String text1;
    private String text2;
    RadioButton button1;
    RadioButton button2;
    Button selectall;
    Context thiscontext;

    static LayoutFragment init(int val) {
        LayoutFragment truitonFrag = new LayoutFragment();
        // Supply val input as an argument.
        Bundle args = new Bundle();
        args.putInt("val", val);
        truitonFrag.setArguments(args);
        return truitonFrag;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRetainInstance(true);
        fragVal = getArguments() != null ? getArguments().getInt("val") : 1;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        thiscontext = container.getContext();
        View layoutView = inflater.inflate(R.layout.activity_main, container, false);

        Button myButton = (Button) layoutView.findViewById(R.id.findSelected);
        myButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                StringBuffer responseText = new StringBuffer();
                responseText.append("");

                // Get selected radiobuttons
                if (radioGroup1.getCheckedRadioButtonId() != -1) {
                    text1 = btn.getText().toString();
                    Log.d("Button", "Text 1 : " + text1);
                }

                if (radioGroup2.getCheckedRadioButtonId() != -1) {
                    text2 = btn2.getText().toString();
                    Log.d("Button", "Text 2 : " + text2);
                }


                Toast.makeText(
                        thiscontext,
                        "Data Posting : APPLICATION : "
                                + text1 + " \nDEVICE : " + text2,
                        Toast.LENGTH_LONG).show();
