这系统自带的日历 多多少少 会有弊端 ！

手机版本不一样 操作不一样 所以我们在判断隐藏某一部分之前 还要判断api的版本

这是我要达成的效果图 .png

1.首先继承一下系统自带的日历dialog

public class YearPickerDialog extends DatePickerDialog {

public YearPickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {

super(context, callBack, year, monthOfYear, dayOfMonth);

}

@Override

public void onDateChanged(DatePicker view, int year, int month, int day) {

super.onDateChanged(view, year, month, day);

this.setTitle(year + "年" );

}

}

2.写一个遍历方法

private DatePicker findDatePicker(ViewGroup group) {

if (group != null) {

for (int i = 0, j = group.getChildCount(); i < j; i++) {

View child = group.getChildAt(i);

if (child instanceof DatePicker) {

return (DatePicker) child;

} else if (child instanceof ViewGroup) {

DatePicker result = findDatePicker((ViewGroup) child);

if (result != null)

return result;

}

}

}

return null;

}

3.调用

final Calendar calendar = Calendar.getInstance();

YearPickerDialog dialog= new YearPickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {

@Override

public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

calendar.set(Calendar.YEAR, year);

calendar.set(Calendar.MONTH, monthOfYear);

LogUtils.d(DateUtil.clanderTodatetime(calendar, "yyyy-MM"));

}

},calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DATE));

dialog.show();

DatePicker dp = findDatePicker((ViewGroup) dialog.getWindow().getDecorView());

if (dp != null) {

((ViewGroup)((ViewGroup) dp.getChildAt(0)).getChildAt(0)).getChildAt(1).setVisibility(View.GONE);

}

4.其中的DateUtil 类方法

public static String clanderTodatetime(Calendar calendar, String style) {

SimpleDateFormat formatter = new SimpleDateFormat(style);

return formatter.format(calendar.getTime());

}
