Question

我需要在datepicker对话框中返回选中的值，请查看以下编码，

这是我的适配器类，我使用了datepicker对话框

if (holder.mClientNextvisit.isChecked() == true) {
    holder.SelectDateLayout.setVisibility(View.VISIBLE);

    holder.mClientSelectDate.setOnClickListener(new View.OnClickListener() {

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

            Calendar calender = Calendar.getInstance();
            year = calender.get(Calendar.YEAR);
            month = calender.get(Calendar.MONTH);
            day = calender.get(Calendar.DAY_OF_MONTH);

            Log.d("Selected date", "---->" + day);

            DatePickerDialog dialog = new DatePickerDialog(context, new DateListener(), year, month, day);
            dialog.show();

        }
    });

}

这是我的datesetlistener类

class DateListener implements DatePickerDialog.OnDateSetListener {

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
        int dayOfMonth) {
    // TODO Auto-generated method stub
    int mYear = year;
    int mMonth = monthOfYear;
    int mDay = dayOfMonth;
    StringBuilder date = new StringBuilder().append(mMonth + 1)
            .append("/").append(mDay).append("/").append(mYear)
            .append(" ");

    Log.d("date", "---->" + date);

}

现在我需要在适配器类中返回所选日期，请帮助我。

如何使用匿名类？

DatePickerDialog dialog = new DatePickerDialog(context,
    new OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker arg0, int arg1, int arg2,
            int arg3) {
            int mYear = year;
            int mMonth = monthOfYear;
            int mDay = dayOfMonth;
            StringBuilder date = new StringBuilder()
                .append(mMonth + 1).append("/").append(mDay)
                .append("/").append(mYear).append(" ");

            Log.d("date", "---->" + date);

        }
    }, year, month, day);

假设mHolder为TextView传递对您的侦听器的引用并直接使用它。

class DateListener implements DatePickerDialog.OnDateSetListener {
  private TextView mHolder;
  public DateListener(TextView mHolder) { this.mHolder = mHolder; }
  @Override
  public void onDateSet(DatePicker view, int year, int monthOfYear,
        int dayOfMonth) {
    // TODO Auto-generated method stub
    int mYear = year;
    int mMonth = monthOfYear;
    int mDay = dayOfMonth;
    StringBuilder date = new StringBuilder().append(mMonth + 1)
            .append("/").append(mDay).append("/").append(mYear)
            .append(" ");

    Log.d("date", "---->" + date);
    mHolder.setText(date);
}

DatePickerDialog dialog = new DatePickerDialog(
context, new DateListener(mHolder), year,month, day);
dialog.show();

需要在android中返回datepicker对话框值
