我有一个CheckBox对话框，每当我在对话框中选择一些值/项目然后关闭对话框，然后重新打开对话框时，我之前选择的所有值/项目都消失了。
我已经用Google搜索并查看了我能找到的每个帖子，从我看到的，使用SharePreferences将是最好的解决方案。我已经设置了每次选中checkBox时，它会在sharepreferences中存储一个值。现在，我仍然试图根据这些值来检查复选框。
任何指导都将不胜感激，谢谢。
这就是我已经拥有的，谢谢你看：
AlertDialog dialog;
final CharSequence[] items = { "All listings", "Buy it now",
"Auction", "Nearest first" };
// arraylist to keep the selected items
final ArrayList<Integer> seletedItems = new ArrayList<Integer>();
final SharedPreferences shfObject = getActivity()
.getSharedPreferences("NAME", Context.MODE_PRIVATE);
final SharedPreferences.Editor shfEditorObject = shfObject.edit();
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Filter");
builder.setMultiChoiceItems(items,
new boolean[] { true, false, false, false, false },
new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog,
final int indexSelected, boolean isChecked) {
if (isChecked) {
if (indexSelected == 0) {
seletedItems.add(indexSelected);
shfEditorObject.putString("checkbox1Ticked", "Ticked1");
shfEditorObject.commit();
}
if (indexSelected == 1) {
seletedItems.add(indexSelected);
shfEditorObject.putString("checkbox2Ticked", "Ticked2");
shfEditorObject.commit();
}
if (indexSelected == 2) {
seletedItems.add(indexSelected);
shfEditorObject.putString("checkbox3Ticked", "Ticked3");
shfEditorObject.commit();
}
if (indexSelected == 3) {
seletedItems.add(indexSelected);
shfEditorObject.putString("checkbox4Ticked", "Ticked4");
shfEditorObject.commit();
}
else if (seletedItems.contains(indexSelected)) {
// Else, if the item is already in the
// array, remove it
// write your code when user Uchecked the
// checkbox
}
}
}
})
// Set the action buttons
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int id) {
// Your code when user clicked on OK
// You can write the code to save the
// selected item here
FILTER1 = shfObject.getString("FILTER",
null);
FILTER2 = shfObject.getString("FILTER2",
null);
Postcode = shfObject.getString("POSTCODE",
null);
findItemsAdvanced(1,
DEFAULT_ENTRIES_PER_PAGE, true,
Postcode, "Citroen c1", FILTER1,
FILTER2);
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int id) {
// Your code when user clicked on Cancel
}
});
dialog = builder.create();// AlertDialog dialog; create like this
// outside onClick
dialog.show();
