Question

我想使用数字日期选择器对话框和时间戳对话框，我已经写了代码，我的选择器对话框正在运行，但我希望它们采用其他格式。

目前，我的时间选择器和日期选择器对话框采用以下格式：

我希望他们这样：

这是我的代码：

    public void onClick(View v) {
            int id = v.getId();
            switch(id){

                case R.id.linearDate: {

                    DatePickerDialog dp = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
                        @Override
                        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                            mDatetext.setText(dayOfMonth+"-"+monthOfYear+"-"+year);

                        }
                    },year,month,day);
                    dp.show();
                }break;

                case R.id.linearTime: {

                    TimePickerDialog Tp = new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                            mTimetext.setText(hourOfDay+ ":" +minute);

                        }
                    },hour,min,false);
                    Tp.show();
                }break;
                case R.id.linearPlace:{ startActivityForResult(new Intent(this,Location.class),CITY);

                }break;
            }
        }

Answer 1

非常简单，我的代码工作正常，我需要添加主题及其完成

case R.id.linearDate: {

                DatePickerDialog dp = new DatePickerDialog(this,android.R.style.Theme_Holo_Light_Dialog,new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                        mDatetext.setText(dayOfMonth+"-"+monthOfYear+"-"+year);

                    }
                },year,month,day);
                dp.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
                dp.show();
            }break;

            case R.id.linearTime: {

                TimePickerDialog Tp = new TimePickerDialog(this,android.R.style.Theme_Holo_Light_Dialog, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                        mTimetext.setText(hourOfDay+ ":" +minute);

                    }
                },hour,min,false);
                Tp.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
                Tp.show();
            }break;

Answer 2

虽然这是一个迟到的答案，但 Nougat 设备中存在 TimePickerDialog 主题的错误。在找到此修复程序之前我无法找到解决方案，这可能有助于搜索相同的人。

创建扩展 TimePickerDialog

的自定义 TimePickerDialogFixedNougatSpinner 类

并按以下方式自定义： -

 public TimePickerDialogFixedNougatSpinner(Context context, int themeResId, OnTimeSetListener listener, int hourOfDay, int minute, boolean is24HourView) {

    super(context, themeResId, listener, hourOfDay, minute, is24HourView);
    fixSpinner(context, hourOfDay, minute, is24HourView);
}

private void fixSpinner(Context context, int hourOfDay, int minute, boolean is24HourView) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { // android:timePickerMode spinner and clock began in Lollipop
        try {
            // Get the theme's android:timePickerMode
            final int MODE_SPINNER = 2;
            Class<?> styleableClass = Class.forName("com.android.internal.R$styleable");
            Field timePickerStyleableField = styleableClass.getField("TimePicker");
            int[] timePickerStyleable = (int[]) timePickerStyleableField.get(null);
            final TypedArray a = context.obtainStyledAttributes(null, timePickerStyleable, android.R.attr.timePickerStyle, 0);
            Field timePickerModeStyleableField = styleableClass.getField("TimePicker_timePickerMode");
            int timePickerModeStyleable = timePickerModeStyleableField.getInt(null);
            final int mode = a.getInt(timePickerModeStyleable, MODE_SPINNER);
            a.recycle();
            if (mode == MODE_SPINNER) {
                TimePicker timePicker = (TimePicker) findField(TimePickerDialog.class, TimePicker.class, "mTimePicker").get(this);
                Class<?> delegateClass = Class.forName("android.widget.TimePicker$TimePickerDelegate");
                Field delegateField = findField(TimePicker.class, delegateClass, "mDelegate");
                Object delegate = delegateField.get(timePicker);
                Class<?> spinnerDelegateClass;
                if (Build.VERSION.SDK_INT != Build.VERSION_CODES.LOLLIPOP) {
                    spinnerDelegateClass = Class.forName("android.widget.TimePickerSpinnerDelegate");
                } else {
                    // TimePickerSpinnerDelegate was initially misnamed TimePickerClockDelegate in API 21!
                    spinnerDelegateClass = Class.forName("android.widget.TimePickerClockDelegate");
                }
                // In 7.0 Nougat for some reason the timePickerMode is ignored and the delegate is TimePickerClockDelegate
                if (delegate.getClass() != spinnerDelegateClass) {
                    delegateField.set(timePicker, null); // throw out the TimePickerClockDelegate!
                    timePicker.removeAllViews(); // remove the TimePickerClockDelegate views
                    Constructor spinnerDelegateConstructor = spinnerDelegateClass.getConstructor(TimePicker.class, Context.class, AttributeSet.class, int.class, int.class);
                    spinnerDelegateConstructor.setAccessible(true);
                    // Instantiate a TimePickerSpinnerDelegate
                    delegate = spinnerDelegateConstructor.newInstance(timePicker, context, null, android.R.attr.timePickerStyle, 0);
                    delegateField.set(timePicker, delegate); // set the TimePicker.mDelegate to the spinner delegate
                    // Set up the TimePicker again, with the TimePickerSpinnerDelegate
                    timePicker.setIs24HourView(is24HourView);
                    timePicker.setCurrentHour(hourOfDay);
                    timePicker.setCurrentMinute(minute);
                    timePicker.setOnTimeChangedListener(this);
                }
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}

确保在fixSpinner函数中传递MODE_SPINNER = 2

Answer 3

通过扩展android.support.v4.app.DialogFragment的对话框实现此目的。

public class DatePickerFragment extends DialogFragment
      implements DatePickerDialog.OnDateSetListener {

    @Override public Dialog onCreateDialog(Bundle savedInstanceState) {
      // Use the current date as the default date in the picker
      final Calendar c = Calendar.getInstance();
      int year = c.get(Calendar.YEAR);
      int month = c.get(Calendar.MONTH);
      int day = c.get(Calendar.DAY_OF_MONTH);

      // Create a new instance of DatePickerDialog and return it
      return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
     //action on date selection
    }
  }

同样适用于TimePicker

Answer 4

可能有帮助

int mHour,mMinute;
TimePickerDialog Tp = new TimePickerDialog(getContext(),R.style.abirStyle, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                        //mTimetext.setText(hourOfDay+ ":" +minute);

                    }
                },mHour,mMinute,false);
                Tp.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
                Tp.show();

样式

中的

<style name="abirStyle" parent="@android:style/Theme.Holo.Light.Dialog.NoActionBar">
    <item name="android:textColor">@color/colorPrimary</item>
    <item name="android:background">@null</item>
    <item name="android:textColorPrimary">@color/colorPrimary</item>
</style>

Answer 5

我想出了如何在不使用Dialog的情况下使用数字TimePicker。他们实现了一项功能，您只需将布局资源文件中TimePicker的timePickerMode属性设置为spinner或clock。
