仅显示android

Question

仅在Android中的棒棒糖5.0上显示月份和年份的日期选择器，它可以在较低版本中完成，但我怎样才能在android 5.0中完成。

Answer 1

这可以通过将DatePicker设置为微调模式并获取来完成 Spinner for Day并以编程方式隐藏它。

这是XML（dialog_date_picker.xml）：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:padding="8dp"
    android:layout_height="match_parent">

    <DatePicker
        android:id="@+id/date_picker"
        android:layout_width="match_parent"
        android:calendarViewShown="false"
        android:datePickerMode="spinner"
        android:layout_weight="4"
        android:layout_height="0dp"
        />

    <Button
        android:id="@+id/date_time_set"
        android:layout_weight="1"
        android:layout_width="match_parent"
        android:text="Set"
        android:layout_height="0dp" />

</LinearLayout>

这是执行此操作的代码。

private Calendar mCalendar;
...

mCalendar = Calendar.getInstance();

final View dialogView = View.inflate(this, R.layout.dialog_date_picker, null);
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();

DatePicker datePicker = (DatePicker) dialogView.findViewById(R.id.date_picker);

datePicker.init(mCalendar.get(Calendar.YEAR),mCalendar.get(Calendar.MONTH),mCalendar.get(Calendar.DAY_OF_MONTH),null);


LinearLayout ll = (LinearLayout)datePicker.getChildAt(0);
LinearLayout ll2 = (LinearLayout)ll.getChildAt(0);
ll2.getChildAt(0).setVisibility(View.INVISIBLE);

dialogView.findViewById(R.id.date_time_set).setOnClickListener(new View.OnClickListener()
{
  @Override
  public void onClick(View view)
  {    
    DatePicker datePicker = (DatePicker) dialogView.findViewById(R.id.date_picker);

    mCalendar = new GregorianCalendar(datePicker.getYear(),
    datePicker.getMonth(),
    datePicker.getDayOfMonth());

    alertDialog.dismiss();
    }
});

这适用于所有Android版本（api> 11）

datePicker.findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE);

我写了一个简单的，希望它可以帮助你

final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    DatePickerDialog dpd = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                    txtDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);
                }
            }, mYear, mMonth, mDay);
    dpd.show();
