如何显示微调器类型的数据对话框片段？

Question

我正在尝试创建一个旋转器类型的数据对话框。像这样：

这是到目前为止的代码：DatePickerFragment：

public class DatePickerFragment extends DialogFragment {
    DatePickerDialog.OnDateSetListener ondateSet;
    private int year, month, day;

    public DatePickerFragment() {
    }

    public void setCallBack(DatePickerDialog.OnDateSetListener ondate) {
        ondateSet = ondate;
    }

    @SuppressLint("NewApi")
    @Override
    public void setArguments(Bundle args) {
        super.setArguments(args);
        year = args.getInt("year");
        month = args.getInt("month");
        day = args.getInt("day");
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), ondateSet, year, month, day);
        return datePickerDialog;
    }
}

和部分主要代码：

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showDatePicker();
            }
        });



...



    private void showDatePicker() {
        DatePickerFragment date = new DatePickerFragment();
        Calendar calender = Calendar.getInstance();
        Bundle args = new Bundle();
        args.putInt("year", calender.get(Calendar.YEAR));
        args.putInt("month", calender.get(Calendar.MONTH));
        args.putInt("day", calender.get(Calendar.DAY_OF_MONTH));
        date.setArguments(args);
        date.setCallBack(new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                editText.setText(String.valueOf(dayOfMonth) + "/" + String.valueOf(month + 1)
                        + "/" + String.valueOf(year));
            }
        });
        date.show(getFragmentManager(), "Date Picker");
    }

在这种情况下，我可以将datePickerMode设置为微调器吗？供您参考，我正在使用片段。

提前感谢！

Answer 1

是的，您可以如下设置android:datePickerMode至spinner，您将获得此输出。

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:datePickerMode="spinner"/>

您还可以在这两页上找到有关如何自定义此内容的更多信息。

1. Datepicker 1
2. Datepicker 2

Answer 2

好，我找到了答案。

我刚刚更改了AppTheme样式：

<style name="AppTheme"  parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="colorControlActivated">@color/colorPrimary</item>
    <item name="android:timePickerDialogTheme">@style/PickerDialogCustom</item>
    <item name="android:datePickerDialogTheme">@style/PickerDialogCustom</item>
    <item name="alertDialogTheme">@style/AlertDialogCustom</item>
</style>

<style name="PickerDialogCustom" parent="AlertDialogCustom">
    <item name="android:textColor">@color/colorPrimary</item>
    <item name="android:textColorPrimary">@color/colorPrimaryDark</item>
    <item name="colorControlNormal">@color/greyLight500</item>
    <item name="android:layout_margin">2dp</item>
    <item name="android:datePickerMode">spinner</item>
</style>

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorAccent">@color/colorPrimary</item>
    <item name="android:positiveButtonText">@color/colorPrimary</item>
    <item name="android:negativeButtonText">@color/greyDark200</item>
    <item name="buttonBarNegativeButtonStyle">@style/negativeButton</item>
    <item name="android:datePickerStyle">@style/PickerDialogCustom</item>
</style>
