我正在使用自定义 DatePicker，但在 Month 字段中遇到问题。当我在 DatePicker 中选择 May 月份时，它看起来不太好。并且仅在 320 X 480 Xpheria 设备中显示。
我得到了如图所示的视图
其余所有值均正确显示。
我正在使用下面的 xml 代码。
<DatePicker
android:id="@+id/dpResult"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/tvDate"
android:layout_marginTop="5dp" />

setCurrentDateOnView();
//addListenerOnButton();
_setButton = (Button)findViewById(R.id.set_button);
_setButton.setOnClickListener(this);
_cancelButton = (Button)findViewById(R.id.cancel_button);
_cancelButton.setOnClickListener(this);
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
//showDialog(DATE_DIALOG_ID);
_datePicker = (DatePicker)findViewById(R.id.dpResult);
System.out.print(_datePicker.getDayOfMonth());
try{
java.lang.reflect.Field[] f = _datePicker.getClass().getDeclaredFields();
for (java.lang.reflect.Field field : f) {
if (field.getName().equals("mDaySpinner") ||field.getName().equals("mDayPicker")) {
field.setAccessible(true);
Object yearPicker = new Object();
yearPicker = field.get(_datePicker);
((View) yearPicker).setVisibility(View.GONE);
}
}
}catch(Exception e){
e.printStackTrace();
}
}
// display current date
public void setCurrentDateOnView() {
tvDisplayDate = (TextView) findViewById(R.id.tvDate);
dpResult = (DatePicker) findViewById(R.id.dpResult);
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
currentYear = year;
month = c.get(Calendar.MONTH);
currentMonth = month;
day = c.get(Calendar.DAY_OF_MONTH);
// set current date into textview
// Month is 0 based, just add 1
/* tvDisplayDate.setText(new StringBuilder()
.append(month + 1).append("-").append(day).append("-")
.append(year).append(" "));*/
// set current date into datepicker
if(Constant.SELECTED_YEAR!=0 && Constant.SELECTED_MONTH_INTEGER!=0)
dpResult.init(Constant.SELECTED_YEAR, Constant.SELECTED_MONTH_INTEGER, day, null);
