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在于,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);
}

}

在您的片段管理器中添加 .addNumberPickerDialogHandler(yourclassname.this) 检查下面的代码...它对我有用

FragmentManager fragManager = getFragmentManager();
NumberPickerBuilder npb = new NumberPickerBuilder()
    .addNumberPickerDialogHandler(CashTransaction.this)
    .setFragmentManager(fragManager)
    .setStyleResId(R.style.BetterPickersDialogFragment_Light);

  npb.show();

enter code here

在调用 NumberPickerBuilder 时,您必须设置setTargetFragment

thisfragment.this-> 当前片段。

  NumberPickerBuilder npb = new NumberPickerBuilder()
                        .setFragmentManager(activity.getSupportFragmentManager())
                        .setStyleResId(R.style.BetterPickersDialogFragment)
                        .setTargetFragment(this) // or .setTargetFragment(fragment.this)
                        .setLabelText(getString(R.string.day_c));
