frag = DateDialogFragment.newInstance(getActivity(),
new DateDialogFragmentListener() {
public void updateChangedDate(int year, int month,
int day) {
button.setText(String.valueOf(day) + "-"
+ String.valueOf(month + 1) + "-"
+ String.valueOf(year));
now.set(year, month, day);
}
}, now);
frag.show(ft, "DateDialogFragment");
您应该使用android.support.v4.app.FragmentManager
而不是android.app.FragmentManager
像这样打电话会有帮助的
调用getSupportFragmentManager（）
但不调用getFragmentManager（）
参考此文档：我仍然在显示错误，您能给我显示ShowDialogUpdate的代码吗？请检查此确定，将错误从该错误切换到frag.show（ft，“DateDialogFragment”）而且它似乎已经是正确的了…..我在这里有点不知所措，忘了提到时间选择器仍然不起作用，它抛出了以下内容07-07 20:29:31.030:E/AndroidRuntime（664）：在com.deano.dfw.BookNowFragment$6.updateChangeTime（BookNowFragment.java:253）07-07 20:29:31.030:E/AndroidRuntime（664）：在com.deano.dfw.TimePickerFragment$1.onTimeSet（TimePickerFragment.java:55）
这是另一个问题，第一个问题解决了，对吗？然后接受它作为anser…在这里发布错误相关日志将有助于解决问题
