问题描述
嗨！
我需要帮助.我尝试扩展按钮类.一切正常，但是如果我添加匿名类型，则在设计模式下会出现错误！下面的代码段:
Hi!
I need help. I try to extend button class. Everything is ok, but if I add anonymous type I have an error in design mode! Code snippet below:
public class ExtDatePicker extends Button {
private int mYear;
private int mMonth;
private int mDay;
private View view = new View(getContext());
private DatePickerDialog.OnDateSetListener mDateSetListener;
public ExtDatePicker(Context context, AttributeSet attrs) {
super(context, attrs);
Init();
}
private void Init(){
// add a click listener to the button
this.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog();
}
});
// the callback received when the user "sets" the date in the dialog
if(!view.isInEditMode()){
//ERROR!!!
/********************** THIS CODE PROVOKE ERROR *****************************/
mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay();
}
};
/****************************************************************************/
}
GetCurrentDate();
updateDisplay();
}
// get the current date
private void GetCurrentDate(){
Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
}
// updates the date in the TextView
private void updateDisplay() {
String day = String.valueOf(mDay);
String month = String.valueOf(mMonth+1);
if(day.length()==1) day="0"+day;
if(month.length()==1) month="0"+month;
this.setText(
new StringBuilder()
// Month is 0 based so add 1
.append(day).append(".")
.append(month).append(".")
.append(mYear));
}
private void showDialog() {
DatePickerDialog dialog = new DatePickerDialog(SharedClass.currentContext,
mDateSetListener, mYear, mMonth, mDay);
dialog.show();
}
}
在运行时模式下效果很好！
错误:
In run-time mode it works great!
