if I am correct you code will crash still with the else if statement when you are trying to unclick an object. Int position is not the index of the integer array list but the index of your item in the dialog list. if you switch it from: else if (chMovieTags.contains(which)) { chMovieTags.remove(which); } to this: else if (chMovieTags.contains(which)) { chMovieTags.remove(chMovieTags.indexOf(which)); } This is far better approach especially with user decisions unless you order the arrayList. I could be wrong though, but I would double check that. I'm still new to the development side trying to have fun. This approach is far better than trying to do an inflated menu list Great job! Saved me time and messy code
Thanks for the awesome tutorials. Just one note: You clear the list mUserItems (line 77) and set the text of mItemSelected to "" (line 88) inside a loop ( doing the same thing multiple times which is unnecessary )
Good tutorial, but there is a flaw in your code. You have to remove the item by their index position in mUserItems, NOT by the integer value of the item in the list. Otherwise you'll get array error. So, when removing an item, the code should be like this: if (isChecked) { if (!mUserItems.contains(position)) { mUserItems.add(position); } } else { if (mUserItems.contains(position)) { mUserItems.remove(mUserItems.indexOf(position)); } }
I would like to display the checkboxes immediately the app opens, and only show the 'MAKE AN ORDER' button on the second screen that displays the selected items. Even better, I'd like the 'Clear All' button to deselect all the check boxes while remaining in the same screen. Any suggestions, gentlemen?
Coding Demos, How can I add Selected itens in various TextView? example: Food TextView: (Selected Item) TextView of cookies: (selected item) IS possible??
Hi. I did this tutorial and it works, but I need to put a value on each checkboxes whenever I checked it and send it to String and add every value I checked. How can I do that? I really need your help. Thanks.
Hi, i'm sorry but what you are asking is already shown in the video. Is it possible if you explain in detail and you are welcome to send me your code (codingdemos@gmail.com) and i'll do my best to help you :)
hi .. how can we limit the selection count like max 4 item can be selected can it be down by keep track the lent of added item in the array list and if it exceed we do on onclick of multiple choice method Checkeditems [Position] = false ;
Hi, sorry for the late reply. Yeah that can work and you also need to check whether the list have exceeded the maximum items that can be added or not like this: if(isChecked){ if(mUserItems.size() < 4) { mUserItems.add(position); }else{ checkedItems[position] = false; } }else{ mUserItems.remove((Integer.valueOf(position))); }
Hi! Coding Demons! I have created a listview by sqlite database.. Instead of making custom list in the dialog box, I want to have the list that I created by sqlite db.. So, How to load that list to dialog?
Removing Items Error Explanation: The parameter "int position" represents the checked item's position in the list: "listItems" (e.g. Onion = 0, Sausage = 1, Milk = 2) If Onion and Milk is checked Array: mUserItems shows [0, 2] Later, if we unchecked "Milk" the position passed to the onClick function is 2. But the size of Array: mUserItems is just 2, therefore no item with position 2 can be removed, and crash happened. Solution: To search the item position in Array: mUserItems with value 2, with a for loop. In the above case (Array: mUserItems shows [0, 2]), to remove "Milk (position index: 2), we need to remove the item of position 1 from Array: mUserItems. Amended Code for removing items from the checked list: public void onClick(DialogInterface dialog, int position, boolean isChecked) { if (isChecked) { if (!mUserItems.contains(position)) { mUserItems.add(position); } } else { for (int i = 0; i < mUserItems.size(); i++) if (mUserItems.get(i) == position) { // mUserItems.remove(i); break; } } }
What could be the best way to display toast when deselect checked item? For example- I select milk and then uncheck, when I do so, it display toast- "You just deselect Milk".
Hmm... What if I used a checkbox as my button? How would I code it so that if an item on the array is checked, the checkbox which I used as my button would also be checked?
I mean in this video, you used a Button to make the AlertDialog appear right? I want to replace that button with a checkbox that is checked when at least 1 item inside the AlertDialog is Selected, and not checked if non are selected This is what I did mAllergies = Checkbox mBuilder.setCancelable(false); mBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { String item = ""; for (int i = 0; i < mUserItems.size(); i++){ item = item + listItems[mUserItems.get(i)]; if(i != mUserItems.size() -1){ item = item + ", "; } } mItemSelected.setText(item); if(mItemSelected.getText() == ""){ mAllergies.setChecked(false); }else{ mAllergies.setChecked(true); } } });

Hi, assuming I saved the checked items to my Firebase, how can I call the checked items from the database to the dialog and get them checked already? Thank you!
selecting all item your shown code below works and selects all the items but when i select "select all" button the dialog box doesn't stay...it vanishes.Basically i am wanting to do click select all-->click ok-->selected item shown in the textView..plz ans
Hi, I made a video tutorial that will show you how to prevent the alertdialog from vanish: th-cam.com/video/9bzxSwqBf74/w-d-xo.html After you follow that tutorial and you get it working, here is the code for the select all option: ListView list = ((AlertDialog) mDialog).getListView(); --> write this after dialog.show(); Inside alertdialog button onClick method you add the following code: mUserItems.clear(); for(int m = 0; m < list.getCount(); m++) { checkedItems[m] = true; list.setItemChecked(m, true); mUserItems.add(m); }
Those that have an error removing the position is that the position is being deleted and not the object, that is, mUserItem.remove(int) is executed and not mUserItem.remove(Object o); to resolve to declare an Integert integer - position; mUserItem.remove(integer);
@@CodingDemos it doesn't work with it please share the code ! i want to save it whenever user click on button does changes to check list it save it for small time when again user click on that button but whenever user come on that activity it shows all checked items but i can do changes according to functionalty of check n uncheck but again if user click on button it shows all checked

nice but in -> (mBuilder.setNeutralButton) Maybe type (mUserItems.clear();) and (mItemSelecter.settext("");) in outside if (For) Because this operation need just one time run! nice try :)
mBuilder.setNegativeButton("Dismiss", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); What does this do exactly? Does it close the the Dialog? The checkbox becomes unchecked when I dismiss it with checked values.
Hi, setNegativeButton is used to set a button on the AlertDialog, while dialog.dismiss() is use to close/dismiss the whole dialog from the user screen. The reason those checkbox becomes unchecked is because you are not saving the values of the checkbox. Its best if you save the checkbox values inside setPositiveButton onClick method
hey hiiii. your this code from in OnClick method give arrayBound error, when i selected or remove items randomly.. your code >>> if(isChecked){ if( ! mUserItems.contains(position)) { mUserItems.add(position); } }else if (mUserItems.contains(position)) { mUserItems.remove(position); } but i update the Onclick method.. my code>>> if(ischecked){ mUserItems.add(position); }else{ mUserItems.remove((Integer.valueOf(position))); } This works fine when selected or remove Items randomly..

suppose if I have multiple spinners with different values, based upon selected values I have to open the new activity So how can I do that?? Can anyone Help me!?
Hi, you can do it like this: mBuilder.setSingleChoiceItems(listItems, -1, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { } }); - listItems: Is the list that contain the data - checkedItem: If you want to specify which item you want it to be checked, here we are setting it to (-1) because we don't want any items to be checked. I hope that helps :)
Hi, you will need to create a listview to display those selected items and an adapter in order to hold those items for you like this: - Add a listview inside activity_main.xml file - Inside mBuilder.setPositiveButton onClick method you add the following code: List myList = new ArrayList(Arrays.asList(items.split(","))); ArrayAdapter mAdapter = new ArrayAdapter(MainActivity.this, android.R.layout.simple_list_item_1, myList); mList.setAdapter(mAdapter); I hope that helps :)
i tried n failed with spinner. I have create a spinner onitemselection n their i was able to get the recycle row position but the challenge i was facing was from there i couldnt update the row item value.
Hi, you can create a custom listview/recyclerview. You create an XML file where you will add a checkbox and a textview. Then you will use this file inside the adapter.

Hi! Coding Demons!
I have created a listview by sqlite database.. Instead of making custom list in the dialog box, I want to have the list that I created by sqlite db.. So, How to load that list to dialog?
Thank you very much sir, Guys refer github link for error.
Removing Items Error Explanation:
The parameter "int position" represents the checked item's position in the list: "listItems"
(e.g. Onion = 0, Sausage = 1, Milk = 2)
If Onion and Milk is checked
Array: mUserItems shows [0, 2]
Later, if we unchecked "Milk"
the position passed to the onClick function is 2.
But the size of Array: mUserItems is just 2, therefore no item with position 2 can be removed, and crash happened.
Solution:
To search the item position in Array: mUserItems with value 2, with a for loop.
In the above case (Array: mUserItems shows [0, 2]),
to remove "Milk (position index: 2),
we need to remove the item of position 1 from Array: mUserItems.
Amended Code for removing items from the checked list:
public void onClick(DialogInterface dialog, int position, boolean isChecked) {
if (isChecked) {
if (!mUserItems.contains(position)) {
mUserItems.add(position);
}
} else {
for (int i = 0; i < mUserItems.size(); i++)
if (mUserItems.get(i) == position) {
//
mUserItems.remove(i);
break;
}
}
}
simply write: mUserItems.remove(mUserItems.indexOf(position))
I really appreciate your help man, thanks alot!
Hey, can you help me with the logic of prepopulating the correct checkboxes based on the indexes i store in the database for the listitems.

ok
Your setMultipleChoiceItems(..) should look like

This will fix if you select an item, hit ok, then deselect same item and hit ok.
the "mIndicesSelected.remove((Integer)i);" needs to be casted or else it tries to remove at that position rather than remove that number at "some" position

i have error in isChecked
Hi, may I know what is the error message?
@@CodingDemos I have the error too, mine says 'error: cannot find symbol variable isChecked'
@@CodingDemos fixed it by making a public boolean isChecked above the onCreate function however now my text view will not display the text from the selected items.
@@CodingDemos fixed by just changing isChecked to checked.
Also is there a way to make the checkboxes say one thing but output different text?
The selected list is unable to copy
Do you get any error message in the logcat?
No but i am unable to copy the content what I have selected
Copying the content to a textview?
@@CodingDemos yes
to fix errors: mUserItems.remove(mUserItems.indexOf(position));
Wrong. All dialogs should be in a fragment.
If I want to display recycler view of only for those which I hv selected from dialogue box.Thn hw vl I do it?can u help me
