android – 从单个对话片段获取日期和时间选择器值,并将其设置为EditText

@H_404_1@我正在处理用户可以设置日期和时间的应用程序.我想在单个对话片段中设置日期和时间,并将其设置为编辑文本.可以在1个对话片段中使用日期和时间选择器吗？如果是这样,你怎么做？
目前,我正在从对话片段中获取时间,然后将其设置为EditText.

我的代码是

LaterTextView=(TextView)findViewById(R.id.PickUp_later_TextView);



       LaterTextView.setOnClickListener(new View.OnClickListener() {

            @SuppressWarnings("deprecation")
            public void onClick(View v) {
                showDialog(TIME_DIALOG_ID);

                }
        });




}


protected Dialog onCreateDialog(int id) {
    switch (id) {
    case TIME_DIALOG_ID:

        // set time picker as current time
        return new TimePickerDialog(this,timePickerListener,hour,minute,false);

    }
    return null;
}

private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() {
    public void onTimeSet(TimePicker view,int selectedHour,int selectedMinute) {
        hour = selectedHour;
        minute = selectedMinute;

        // set current time into TextView
        setDate_time_EditTExt.setText(new StringBuilder().append(pad(hour))
                .append(":").append(pad(minute)));



    }
};
private static String pad(int c) {
    if (c >= 10)
        return String.valueOf(c);
    else
        return "0" + String.valueOf(c);
}

我想从相同的对话框片段设置日期和时间.

解决方法

日期选择器和时间选择器都在单个对话框中.检查这个代码.
