为什么timepickerdialog对话框不显示

public class MainActivity extends Activity {
Calendar calendear=null;
TextView tv;
Button btn;
final int MYDIALOG=1;
@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
// TODO Auto-generated method stub
Dialog dialog=null;
switch (id) {
case MYDIALOG:
Builder builde=new AlertDialog.Builder(this);
calendear=Calendar.getInstance();
dialog=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {

@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
tv.setText("您设置的时间为："+hourOfDay+"点"+minute+"分");
}
}, calendear.get(Calendar.HOUR_OF_DAY), calendear.get(Calendar.MINUTE), true);
dialog=builde.create();
break;
default:
break;
}
return dialog;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
super.onCreate(savedInstanceState);
tv=(TextView)findViewById(R.id.textView1);
btn=(Button)findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {

@SuppressWarnings("deprecation")
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showDialog(MYDIALOG);
}
});
}
