Hi,
Actually, dialog remembers previous state is good but it always does even
though you press OK button or CANCEL button.
When creating a dialog, i use an array to store checkbutton's states. So
when user presses CANCEL, i do not update this state array.
Ex: At first time, when i create dialog, i initial new_state_array
={true,true,true}.
After that user unchecked first and second checkbox item, then pressing
CANCEL.
It is great if dialog still displays 3 checkbox item in checked state on
next time but it only display third checkbox item in checked state.
Please see my code below and give me advices to solve that problem.
**********************************************************************************
.setMultiChoiceItems(R.array.select_map_mod,
new_state_array,* /*<--- So when recreate Dialog,it
must update state but it seems to me that it doesnot work except the first
time**/
new DialogInterface.OnMultiChoiceClickListener()
{
public void onClick(DialogInterface dialog, int
whichButton,
boolean isChecked)
{
new_state_array[whichButton] = isChecked;
/* User clicked on a check box do some stuff
*/
}
})
.setPositiveButton(R.string.alert_dialog_ok, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton)
{
/* User clicked Yes so do some stuff */
for(int i=0;i<3;i++) old_state_array[i] =
new_state_array[i];
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton)
{
/* User clicked No so do some stuff */
for(int i=0;i<3;i++) new_state_array[i] =
old_state_array[i];
}
})
