Question

我有一个DatePicker，其中有一个按钮，可以让DialogBox选择日期，还有一个EditText txtDate来设置日期：

Layout：

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal" >

            <TextView
                android:id="@+id/date_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_weight="1.50"
                android:text="Pickup Date*"
                android:textStyle="bold" />

             <EditText
                 android:id="@+id/txtDatee"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:layout_weight="2.28" >

        </EditText>

              <Button
            android:id="@+id/btnCalendar"
            android:layout_width="30dp"
            android:layout_height="42dp"
            android:layout_marginRight="50dp"
            android:background="@drawable/date" >
        </Button>

        </LinearLayout>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="62dp"
            android:orientation="horizontal" >

            <TextView
                android:id="@+id/textView5"
                android:layout_width="126dp"
                android:layout_height="wrap_content"
                android:text="Pickup Time"
                android:textStyle="bold" />

            <Spinner
                android:id="@+id/hh"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_weight="1" />

            <Spinner
                android:id="@+id/mm"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_weight="1" />
        </LinearLayout>

的onClick [DatePicker]：

public void onClick(View v) {

    if (v == btnCalendar) {

        // Process to get Current Date
        final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);

        // Launch Date Picker Dialog
        DatePickerDialog dpd = new DatePickerDialog(this,
                new DatePickerDialog.OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker view, int year,
                            int monthOfYear, int dayOfMonth) {
                        // Display Selected date in textbox

                         if (year < mYear)
                                view.updateDate(mYear,mMonth,mDay);

                            if (monthOfYear < mMonth && year == mYear)
                                view.updateDate(mYear,mMonth,mDay);

                            if (dayOfMonth < mDay && year == mYear && monthOfYear == mMonth)
                                view.updateDate(mYear,mMonth,mDay);

                        txtDate.setText(dayOfMonth + "-"
                                + (monthOfYear + 1) + "-" + year);

                    }
                }, mYear, mMonth, mDay);
        Date newDate2 = c.getTime();
        dpd.getDatePicker().setMinDate(newDate2.getTime());
        dpd.show();
    }   }

还有两个id为hh和mm的微调器，用于具有静态数组值的小时和分钟。

String[] pickup_hour = { "HH", "00", "01", "02", "03", "04", "05", "06",
        "07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17",
        "18", "19", "20", "21", "22", "23" };

String[] pickup_min = { "MM", "00", "05", "10", "15", "20", "25", "30",
        "35", "40", "45", "50", "55" };



sp3 = (Spinner) findViewById(R.id.hh);

    sp3.setOnItemSelectedListener(new OnItemSelectedListener() {


        @Override
        public void onItemSelected(AdapterView<?> parent, View v,
                int position, long id) {

            edsp3.setText(pickup_hour[position]);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {

        }
    });
    ArrayAdapter b3 = new ArrayAdapter(this,
            android.R.layout.simple_spinner_item, pickup_hour);

    b3.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    sp3.setAdapter(b3);

sp4 = (Spinner) findViewById(R.id.mm);
    sp4.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View v,
                int position, long id) {

            edsp4.setText(pickup_min[position]);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {

        }
    });
    ArrayAdapter b4 = new ArrayAdapter(this,
            android.R.layout.simple_spinner_item, pickup_min);

    b4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    sp4.setAdapter(b4);

根据当前日期，以前的日期禁用DatePicker。那么如何根据DatePicker日期修复小时和分钟？

感谢您的帮助。

编辑：

这就是我在小时内所做的事情：

sp3 = (Spinner) findViewById(R.id.hh);

    sp3.setOnItemSelectedListener(new OnItemSelectedListener() {
        Calendar c1 = Calendar.getInstance(); 


        int hour = c1.get(Calendar.HOUR_OF_DAY);

        @Override
        public void onItemSelected(AdapterView<?> parent, View v,
                int position, long id) {
Log.d("aaa", ""+hour);
            edsp3.setText(pickup_hour[position]);


                         if(position<hour)
                         {
                             Toast.makeText(OnlineBooking.this, "Choose greater hour",
                                        Toast.LENGTH_LONG).show();

        }}

Answer 1

首先，始终建议您使用内置的 DatePicker 和 TimePicker 小部件。

如果您希望使用微调器，则以编程方式填充微调器

 System.currentTimeMillis();

将为您提供设备的当前时间然后检查当前的小时和分钟，并相应地填充微调器

其他方法是通过在提交按钮点击事件

中验证相同的方法

表示使用当前系统时间检查所选时间

Answer 2

根据时钟系统，24小时或12小时系统，获取

Calendar c = Calendar.getInstance(); 
int seconds = c.get(Calendar.SECOND);
int minutes = c.get(Calendar.MINUTE);
int hour = c.get(Calendar.HOUR); // or HOUR_OF_DAY

当调用spinenrs onItemSelected侦听器时，将这些值与您在秒，小时和分钟变量中的值进行比较，并相应地显示该消息。
