我无法以编程方式为v11及更高版本更改机器人动作栏标题颜色.我可以在xml中完成它,但需要在代码中动态更改它.我该怎么办呢？提前致谢.

我正在使用DialogFragment在onCreateDialog()中返回DatePickerDialog.我已将dateSetListener设置为DialogFragment(下面的示例中为"this"),除了在屏幕旋转发生时调用onDateSet()时,一切正常,这是不可取的.如何在旋转屏幕时让onDateSet不被调用？

我的DialogFragment

public static class DateDialogFragment extends DialogFragment implements
DatePickerDialog.OnDateSetListener{

    public static DateDialogFragment newInstance() {
        return new DateDialogFragment();
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new DatePickerDialog(getActivity(), this, 2012, 11, 19);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
        int dayOfMonth) {
        //This is called when screen rotated, which I dont want
        Toast.makeText(getActivity(), "Year: "+year+" Month: "+monthOfYear+" Day: "+dayOfMonth, Toast.LENGTH_SHORT).show();
    }

}

这就是我所说的

if(getActivity()!=null){
    FragmentManager fm = getActivity().getSupportFragmentManager();
    DialogFragment newFragment = DateDialogFragment.newInstance();
    newFragment.show(fm, "dialog");
}
