我目前正在尝试实现Android BetterPickers库(https://github.com/derekbrameyer/android-betterpickers)。我已经能够显示要求用户选择时间的选择器,但是没有调用该界面提供的方法。方法是https://github.com/derekbrameyer/android-betterpickers/blob/master/sample/src/com/doomonafireball/betterpickers/sample/activity/hmspicker/SampleHmsDefault.java处的第43行。
这是我的代码的样子。我的代码与提供的示例之间的主要区别在于,我的代码是在Fragment中执行的,而不是在Activity中执行(github示例中的第35行)。我使用了getActivity()。getSupportFragmentManager()而不是getSupportFragmentManager()。为什么不调用onDialogHmsSet方法?

btnSetOff.setOnClickListener(this);
btnSetOn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_set_on:
HmsPickerBuilder hpb = new HmsPickerBuilder().
setStyleResId(R.style.BetterPickersDialogFragment)
.setFragmentManager(getActivity().getSupportFragmentManager();
hpb.show();
break;
case R.id.btn_set_off:

}
}
@Override
public void onDialogHmsSet(int reference, int hours, int minutes, int seconds) {
Assert.assertTrue(false);
}
}
