在onTimeSet方法中的赋值语句会被执行两次，后发现这个方法会被执行那个两次
monthEnd = monthEnd+1;
Log.e("month==value", "month:"+monthEnd);
本来系统的月份比实际少一个月，加1就可以了，点一次执行两次就相当于，我选的7月，而实际却变成了9月。
onDateSet方法把month的值赋值给了成员monthMember即monthMember = month，在onTimeSet中把month+1设置给了textview，即textview.setText(month+1),这个时候就会自动加2，所以避免这种执行两次的情况。
网上一搜，说这是android4.1和4.2存在的一个bug，点击确定和取消按钮时，会出发onTimeSet；在dialog的onStop（比如dialog dismiss时）中，也调用了onTimeSet方法。需要修改framework里的TimePickerDialog.java源文件
所以说复写对话框注掉onStop就行了，
@Override
protected void onStop() {
// TODO Auto-generated method stub
//super.onStop();
}
protected void onStop() {
// TODO Auto-generated method stub
//super.onStop();
}
我的解决办法是
1：在onDateSet方法中monthMember = month+1;来完成赋值，然后再把monthMember设置给textview，onTimeSet中只是完成了textview.settext(monthMember);并没有加1的操作，即使是onTimeSet执行两次也无所谓，不会受到影响。

2：第二种解决办法：
//复写对话框注掉onStop就行了，
@Override
protected void onStop() {
// TODO Auto-generated method stub
//super.onStop();
}
