Question

我想在同一个活动中实现两个波斯语DateTimePickers，但是两个名为“onTimeSet”的方法＆amp; “onDateSet定义一次......

我如何在每个TimePickers和DatePickers的一个活动中两次使用这些方法？

另外我使用这个库：https://github.com/mohamad-amin/PersianMaterialDateTimePicker

import android.os.Bundle;
import android.support.annotation.Nullable;

public class TimeActivity extends AppCompatActivity implements
        TimePickerDialog.OnTimeSetListener,
        DatePickerDialog.OnDateSetListener,
        View.OnClickListener {


    //VARIABLE DEFINITION
    Button btn_start_time = (Button) findViewById(R.id.start_time_button);
    Button btn_start_date = (Button) findViewById(R.id.start_date_button);
    TextView txt_start_time = (TextView) findViewById(R.id.start_time_textview);
    TextView txt_start_date = (TextView) findViewById(R.id.start_date_textview);
    PersianCalendar persianCalendar1 = new PersianCalendar();
    PersianCalendar persianCalendar2 = new PersianCalendar();
    private boolean mode24Hours;


    TimePickerDialog timePickerDialog1;
    DatePickerDialog datePickerDialog1;
    TimePickerDialog timePickerDialog2;
    DatePickerDialog datePickerDialog2;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


    }

    @Override

        switch (v.getId()) {

            case R.id.start_time_button: {

                timePickerDialog1.setThemeDark(false);
                timePickerDialog1.show(getFragmentManager(), "TimePickerDialog");

                /*timePickerDialog1.setOnCancelListener(new DialogInterface.OnCancelListener() {

                        Log.d( "TimePickerDialog", "Dialog was cancelled");
                    }
                });*/
                break;
            }
            case R.id.start_date_button: {
                datePickerDialog1 = DatePickerDialog.newInstance(
                        TimeActivity.this,

                        persianCalendar1.getPersianDay()

                datePickerDialog1.setThemeDark(false);
                datePickerDialog1.show(getFragmentManager(), "TimePickerDialog");
                break;
            }
            case R.id.end_time_button: {

                timePickerDialog2 = TimePickerDialog.newInstance(
                        TimeActivity.this,
                        persianCalendar2.get(PersianCalendar.HOUR_OF_DAY),
                        persianCalendar2.get(PersianCalendar.MINUTE),

                        persianCalendar2.getPersianDay()

                datePickerDialog2.show(getFragmentManager(), "TimePickerDialog");
                break;
            }
            default:
                break;
        }
    }


    @Override
    public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute) {
        String time = "You picked the following time: " + hourOfDay + "h" + minute;
        txt_start_time.setText(time);
    }

    @Override
    public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
        String date = "You picked the following date: " + dayOfMonth + "/" + (monthOfYear + 1) + "/" + year;
        txt_start_date.setText(date);
    }


}

你需要有两个听众

DatePickerDialog.OnDateSetListener one_dateListener,two_dateListener;

监听器实现如下：

one_dateListener= new OnDateSetListener(){

            public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {

                          ...

                }
            }

        };
        two_dateListener= new OnDateSetListener(){
            public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
                .....
            }
        };

在对话框中使用这些侦听器：

int DATE_PICKER_TO = 0;
int DATE_PICKER_FROM = 1;

@Override
protected Dialog onCreateDialog(int id) {

    switch(id){
        case DATE_PICKER_ONE:
                return new DatePickerDialog(this, one_dateListener, from_year, from_month, from_day); 
            case DATE_PICKER_TWO:
                return new DatePickerDialog(this, two_dateListener, to_year, to_month, to_day);
    }
        return null;
}
