How to get gridview multiple positions and store into array variable

Now I am displaying images in grid-view, it working fine. In that grid-view i am going to select few images, i want store selected multiple images position in array variable (example: if i select position 1, 4 ,10. i want that particular position id and i want to store it array like 1,4,10,15,). I will put my activity and adapter code below. Thank you in advance.

It's simple. You can use SparseBooleanArray for this purpose. Just add the following methods as is in your adapter:
public void toggleSelection(int item) {
if (selectedItems.get(item, false)) {
selectedItems.delete(item);
} else {
selectedItems.put(item, true);
}
notifyDataSetChanged();
}
public void setSelectedItems(List<Object> objects) {
if (objects != null) {
for (Object object : objects) {
toggleSelection(object.getId());
}
notifyDataSetChanged();
}
}
public void clearSelections() {
selectedItems.clear();
notifyDataSetChanged();
}
public int getSelectedItemCount() {
return selectedItems.size();
}
public List<Integer> getSelectedItems() {
List<Integer> items =
new ArrayList<Integer>(selectedItems.size());
for (int i = 0; i < selectedItems.size(); i++) {
items.add(selectedItems.keyAt(i));
}
return items;
}
Use the set selection method to store the selected status of your item.
Don't forget to initialize SparseBooleanArray in your constructor.
SparseBooleanArray SparseBooleanArray = new SparseBooleanArray();
After that, use toggleSelection(position); to change the selected status of an item, then after performing selections, call getSelectedItem() to get the selected items in an array.

// create an Arraylist and add the selected position in a list
List <int> selectedArray = new ArrayList<>();
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int click = (int) parent.getItemAtPosition(position);
selectedArray.add(click);
}

How to send checked multiple contacts from list view to another layout in android studio

You should move data manipulation to the adapter, and design-wise it would make sense and might also fix the problem you're telling us.
Write this method in your ProductAdapter:
public void removeSelected() {
for(int i = mProductList.size()-1; i >= 0; i--) {
if(mProductList.get(i).selected) {
mProductList.remove(i);
}
}
notifyDataSetChanged();
}
Update your OnClickListener (in your ShoppingCartActiity of course):
removeButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mProductAdapter.removeSelected();
}
});
Edit
I noticed that you aren't applying OOP's concept of encapsulation here. That is, ShoppingCartActiity shouldn't be making changes to the data which belongs to your adapter.
So, just create public methods inside the ProductAdapter for item for selection, etc and call them from ShoppingCartActiity as needed.
Copy this method in your ProductAdapter:
public void toggleSelection(int position) {
Product selectedProduct = (Product) getItem(position);
if(selectedProduct.selected) { // no need to check " == true"
selectedProduct.selected = false;
}
else {
selectedProduct.selected = true;
}
notifyDataSetInvalidated();
}
mProductAdapter.toggleSelection(position); will replace following code ShoppingCartActiity:
Product selectedProduct = mCartList.get(position);
if(selectedProduct.selected == true)
selectedProduct.selected = false;
else
selectedProduct.selected = true;
mProductAdapter.notifyDataSetInvalidated();
Edit2
The problem is that the ShoppingCartActiity takes items from ShoppingCartEntry on starting up, but it never writes back the changes to it when you remove items.
update your removeButton's onClick() to:
mProductAdapter.removeSelected();
if (product.selected) {
// set products which are remaining in the adapter
ShoppingCartHelper.setProducts(mProductAdapter.getProducts());
}
ShoppingCartHelper.setProducts() would replace the old data with the passed one:
public static void setProducts(ArrayList<Product> products) {
catalog = new Vector<Product>();
for (Product product : products) {
catalog.add(product);
}
}
mProductAdapter.getProducts() will just return the list of Products, like:
public List<Product> getProducts() {
return mProductList;
}

you just have to remove selected item from list, and after adapter.notifiyDataSetChanged() it will refresh the adapter.
removeButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Loop through and remove all the products that are selected
// Loop backwards so that the remove works correctly
for(int i=mCartList.size()-1; i>=0; i--) {
if(mCartList.get(i).selected) {
mCartList.remove(i);
//mProductAdapter.removeSelected();
}
}
if(mProductAdapter!=null)
mProductAdapter.notifyDataSetChanged();
}
});

Adding and removing the item into wish list like flipkart

I want to add / remove the item into wishlist.

Change this line
holder.wish_list.setImageResource(R.drawable.wishlist);
to this
Resources resources = getResources();
holder.wish_list.setImageDrawable(resources.getDrawable(R.drawable.wishlist));
and do the same in else part and check the output..
Note :
getResources().getDrawable is deprecated.
You can try ContextCompat.getDrawable:
holder.wish_list.setImageDrawable(ContextCompat.getDrawable(context,
R.drawable.wishlist));
UpDate :
check this way.
if(state == true){
// here is default icon and set api value and send it
}else{
// here is click wishlist icon and set api value and send it
}

use getListview() in list Activity to get List..........
in Oncreate
ListView lv = getListView();
http://www.mkyong.com/android/android-listview-example/
this link has both ways
1- overriding onListItemClick(
2- Setting you listener..

Try this way..
ListView lv = getListView();
lv. storelist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
}
this are help you.
Thanks

Override the function onlistitemclick() for this. Here the integer position represents the postion of item that you had pressed
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
.......
}

Try this one
getListView().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
}
});
