Android和CheckBox中的线程处理程序问题

Question

我想问一下android线程处理程序问题。

在此代码中有两个“CheckBox”，当我选择它时，必须更改下一个Activity

但是当我将代码添加到线程处理程序中时，无法更改下一个Activity。

我已添加AndroidMainfeat.xml

我想问一下“CheckBox”是否能带来价值。

bundle.putString（ “男孩”，的getText（0）的ToString（）修剪（））;是正确的吗？

感谢。

public class PersonalInformation extends Activity{


    private Button setbutton ;
    private CheckBox boy,girl;

    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_personal_information);
            setTitle("PersonalInformation");

            buildViews();  //user define
        } 

     private void buildViews(){ 

          boy = (CheckBox)findViewById(R.id.boy);
          girl = (CheckBox)findViewById(R.id.girl);         
          setbutton = (Button)findViewById(R.id.setbutton);
          setbutton.setOnClickListener(btsetListener);   
        }
            private OnClickListener btsetListener = new OnClickListener() {     

                public void onClick(View v) {

                    final Handler handler = new Handler();
                    final Runnable callback = new Runnable() {
