我正在测试新的 BetterPickers 库（日期和时间选择器）。在我向我的 xml 文件添加多个按钮之前，一切都很好。通过选择器选择按钮文本后，停止在按钮文本上显示时间。这是我的布局 xml 文件：

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

这是我的代码：Reservation.java

package younga.ines.yourcar;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;

import com.actionbarsherlock.app.SherlockFragment;
import com.doomonafireball.betterpickers.datepicker.DatePickerBuilder;
import com.doomonafireball.betterpickers.datepicker.DatePickerDialogFragment;
import com.doomonafireball.betterpickers.timepicker.TimePickerBuilder;
import com.doomonafireball.betterpickers.timepicker.TimePickerDialogFragment;


public class Reservation extends SherlockFragment implements OnClickListener,
DatePickerDialogFragment.DatePickerDialogHandler,
TimePickerDialogFragment.TimePickerDialogHandler {

private Button ti_depart;
private Button da_depart;
private Button ti_arrive;
private Button da_arrive;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub

    View rootView = inflater.inflate(R.layout.fragment_reservation, container, false);


    //date_depart
    da_depart=(Button)rootView.findViewById(R.id.button2_date_depart);
    da_depart.setOnClickListener(this);

    //time_depart
    ti_depart = (Button) rootView.findViewById(R.id.time_depart5);
    ti_depart.setOnClickListener(this);

    //date_arrive
    da_arrive=(Button)rootView.findViewById(R.id.button5_date_arrive);
    da_arrive.setOnClickListener(this);

    //time_arrive
    ti_arrive=(Button)rootView.findViewById(R.id.button6_time_arrive);
    ti_arrive.setOnClickListener(this);


    return rootView;    }


private void calltoDatedepartPicker() {
    // TODO Auto-generated method stub
    DatePickerBuilder dpb = new DatePickerBuilder()
    .setFragmentManager(getChildFragmentManager())
     .setStyleResId(R.style.BetterPickersDialogFragment)
    .setTargetFragment(Reservation.this);
    dpb.show();   
}
private void calltoTimedepartPicker() {
    // TODO Auto-generated method stub

    TimePickerBuilder tpb = new TimePickerBuilder()
    .setFragmentManager(getChildFragmentManager())
    .setStyleResId(R.style.BetterPickersDialogFragment)
    .setTargetFragment(Reservation.this);
    tpb.show();

}

private void calltoTimearrivePicker() {
    // TODO Auto-generated method stub
    TimePickerBuilder tpb = new TimePickerBuilder()
    .setFragmentManager(getChildFragmentManager())
    .setStyleResId(R.style.BetterPickersDialogFragment)
    .setTargetFragment(Reservation.this);
    tpb.show();

}


private void calltoDatearrivePicker() {
    // TODO Auto-generated method stub
    DatePickerBuilder dpb = new DatePickerBuilder()
    .setFragmentManager(getChildFragmentManager())
     .setStyleResId(R.style.BetterPickersDialogFragment)
    .setTargetFragment(Reservation.this);
    dpb.show();
}




@Override
public void onDialogTimeSet(int reference, int hourOfDay, int minute) {
    // TODO Auto-generated method stub
    // reference argument show -1 as value
    Toast.makeText(getSherlockActivity(), ""+reference, Toast.LENGTH_SHORT).show();
    if(reference==R.id.time_depart5) ti_depart.setText("" + hourOfDay + ":" + minute);
    if(reference==R.id.button6_time_arrive) ti_arrive.setText("" + hourOfDay + ":" + minute);
    }


@Override
public void onDialogDateSet(int reference, int year, int monthOfYear,
        int dayOfMonth) {
    // TODO Auto-generated method stub
    if(reference==R.id.button2_date_depart) da_depart.setText("" + dayOfMonth + "" + monthOfYear + "" + year);
    if(reference==R.id.button5_date_arrive) da_arrive.setText("" + dayOfMonth + "" + monthOfYear + "" + year);

}


@Override
public void onClick(View v) {
    // TODO Auto-generated method stub

    if(v.getId()==R.id.button2_date_depart){
        calltoDatedepartPicker();

    }

    if(v.getId()==R.id.time_depart5){
        calltoTimedepartPicker();

    }

    if(v.getId()==R.id.button5_date_arrive){
        calltoDatearrivePicker();
    }

    if(v.getId()==R.id.button6_time_arrive){
        calltoTimearrivePicker();
    }




}

}

所以我的问题是如何使用 onDialogDataSet 和 onDialogTimeSet 方法 来显示在4 个按钮上选择的时间或日期？？？？

PS：我只用一个按钮就很好用！！提前致谢 。

通过使用标志修复它

@Override public void onDialogTimeSet ( int reference, int hourOfDay, int minute){
                if (flag_time_depart == true) {
                    ti_depart.setText("" + hourOfDay + ":" + minute);
                    flag_time_depart = false;
                }
                if (flag_time_arrive == true) {
                    ti_arrive.setText("" + hourOfDay + ":" + minute);
                    flag_time_arrive = false;
                }
            }
            and without forgetting the Flags declaration as globals vars:
            private boolean flag_time_depart = false;
            private boolean flag_time_arrive = false;

日期选择器示例

        DatePickerBuilder dpb = new DatePickerBuilder()
                .setFragmentManager(getChildFragmentManager())
                .setStyleResId(R.style.BetterPickersDialogFragment_Light)
                .setTargetFragment(Reserva.this);
        dpb.show();
