先看代碼:
@Override
public void onClick(View v) {
final AlertDialog.Builder adb = new AlertDialog.Builder(getApplicationContext());
adb.setView(LayoutInflater.from(getApplicationContext()).inflate(R.layout.custom, null));
adb.setPositiveButton("Add",new android.content.DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int arg1) {
DatePicker datePicker = (DatePicker)findViewById(R.id.datePicker);
java.util.Date date = null;
Calendar cal = GregorianCalendar.getInstance();
cal.set(datePicker.getYear(),datePicker.getMonth(), datePicker.getDayOfMonth());
date = cal.getTime();
}
});
adb.show();
}
在這行裡出現異常:
cal.set(datePicker.getYear(),datePicker.getMonth(), datePicker.getDayOfMonth());
我嘗試了用adb.findViewById();
但是有錯誤:The method findViewById(int) is undefined for the type AlertDialog.Builder
幫忙看一下,謝謝
把DatePicker datePicker = (DatePicker)findViewById(R.id.datePicker);
這一行改成:
DatePicker datePicker = (DatePicker)adb.findViewById(R.id.datePicker);
試下這個:
final AlertDialog.Builder adb = new AlertDialog.Builder(this);
final View view = LayoutInflater.from(getApplicationContext()).inflate(R.layout.main1, null);
adb.setView(view);
final Dialog dialog;
adb.setPositiveButton("Add",new android.content.DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int arg1) {
DatePicker datePicker = (DatePicker)view.findViewById(R.id.datePicker1);
java.util.Date date = null;
Calendar cal = GregorianCalendar.getInstance();
cal.set(datePicker.getYear(),datePicker.getMonth(), datePicker.getDayOfMonth());
date = cal.getTime();
}
});
dialog = adb.create();
dialog.show();
