安卓BetterPickers

Question

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，但未调用界面提供的方法。该方法位于 https://github.com/derekbrameyer/android-betterpickers/blob/master/sample/src/com/doomonafireball/betterpickers/sample/activity/hmspicker/SampleHmsDefault.java 的第 43 行.

这是我的代码的样子。我的代码和提供的示例之间的主要区别是我的代码是在 fragment 中执行的，而不是在 Activity 中执行的(github 示例中的第 35 行)。我使用 getActivity().getSupportFragmentManager() 而不是 getSupportFragmentManager()。为什么不调用 onDialogHmsSet 方法？

import java.util.ArrayList;
import java.util.List;

import junit.framework.Assert;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;
import android.widget.TextView;

import com.doomonafireball.betterpickers.hmspicker.HmsPickerBuilder;
import com.doomonafireball.betterpickers.hmspicker.HmsPickerDialogFragment.HmsPickerDialogHandler;
import com.example.hiittimer.R;

public class NewWorkout extends Fragment implements OnClickListener, HmsPickerDialogHandler {
    private View view;
    private Button btnSetOn, btnSetOff;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.fragment_activity_new_workout, container, false);
    viewHolder = new ViewHolder();
    setViews();
    return view;
}

private void setViews(){
    btnSetOff = (Button) view.findViewById(R.id.btn_set_on);
    btnSetOn = (Button) view.findViewById(R.id.btn_set_off);
    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:
        break;

    default:
        break;
    }
}

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