Button btn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn=(Button)findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Builder builder=new AlertDialog.Builder(SingleCIDemoActivity.this);
builder.setTitle("单选框");
builder.setIcon(android.R.drawable.ic_dialog_info);
builder.setSingleChoiceItems(new String[]{"Item1","Item2","Item3"}, 0, null);
