Checkbox for gridview inside listview in Android

I have a problem statement in my booking app such that user can delete all the booking of the particular date or all the dates, see this image:
I have tried to add data to the grid view using multiple adapters for listview and the inner gridview, but it's taking data replication. How can I solve this problem?
Each date represents the listview with checkbox,and the UH,U1 etc represents the item of gridview. I want to pass the selected venue id ie. UH,U! etc in a listview and its corresponding dates

Try the sample below :)
MainActivity.java:
public class MainActivity extends Activity {
Button clearChecks;
ExpandableListView expandableListView;
ExpandableListGridAdapter expandableListAdapter;
int lastExpandedPosition = -1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
expandableListView = findViewById(R.id.expandedListView);
clearChecks = findViewById(R.id.btnClearChecks);
List<String> listTitle = genGroupList();
expandableListAdapter = new ExpandableListGridAdapter(this, listTitle, genChildList(listTitle));
expandableListView.setAdapter(expandableListAdapter);
expandableListView.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {
#Override
public void onGroupExpand(int groupPosition) {
if(lastExpandedPosition != -1 && (lastExpandedPosition != groupPosition)){
expandableListView.collapseGroup(lastExpandedPosition);
}
lastExpandedPosition = groupPosition;
}
});
clearChecks.setOnClickListener(new View.OnClickListener() {
#Override

expandableListAdapter.clearChecks();
}
});

Filter several ListViews via SearchView

I have implemented precisely ONE ListView (with header attached) filtering according to SearchView input. Now I'm planning to make SearchView filter several ListViews and I wonder how to do it. I'm stuck and have no ideas. The main principle of filtering is such:
We have several categories(i.e. accomodation, places of interest), which serve as headers (basically, the picture of category) displayed with ListViews attached for each of the category. When user enters the search query, the application needs to have all the ListViews filtered at once. The structure of the window is this:
->Header of the current category
ListView #1
When user enters input, all the available categories are displayed and the filter is applied for them:
->Header of the current category
Filtered ListView #1
->Header #2
Filtered ListView #2
...
->Header #8
Filtered ListView #8
I seek for the clearest/most genious way for performing this. Worth to mention, we know the exact count of categories.
I'm posting my code snippets(ONE ListView (with header attached) filtering according to SearchView input). Moreover, I print the message if search returns no results so that the user can contact us, if he desires.

Create adapter for different list views.
Then in the edittext aftertextchange listener apply the text filter for all the adapters. Have a look at:
http://www.androidbegin.com/tutorial/android-search-listview-using-filter/
adapter1 = new ListViewAdapter(this, arraylist1);
list1.setAdapter(adapter1);
adapter2 = new ListViewAdapter(this, arraylist2);
list2.setAdapter(adapter2);
editsearch.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
//TODO Auto-generated method stub
String text = editsearch.getText().toString().toLowerCase(Locale.getDefault());
adapter1.filter(text);
adapter2.filter(text);
....
}

#Riasat's answer inspired me and I think it could be possible to do it without any code repetition: of course for each list view, you'd have a adapter with will be more or less the same. But it could be great to create a notifier, which will say to all the adapter to refresh. Something like:
An interface to go a bit further as your only requirements:
/**
* Created by laurentmeyer on 03/03/15.
*/
public interface RefreshInterface {
void refresh();
void searchForText(String searchedText);
void searchWithSomethingElse(Object SomethingElse);
}
Then modify a bit the adapter:
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Filter;
import android.widget.Filterable;
/**
* Created by laurentmeyer on 03/03/15.
*/
public class CustomListAdapter extends BaseAdapter implements RefreshInterface{
private Context context;
private List<Item> items;
private LayoutInflater inflater;
private ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public CustomListAdapter(Context context, List<Item> items) {
this.context = context;
this.items = items;
}
#Override

return items.size();

#Override

}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_item, null);
if (imageLoader == null)
imageLoader = AppController.getInstance().getImageLoader();
NetworkImageView image = (NetworkImageView) convertView.findViewById(R.id.image);
TextView name = (TextView) convertView.findViewById(R.id.name);
TextView type = (TextView) convertView.findViewById(R.id.type);
Item i = items.get(position);
image.setImageUrl(i.getIcon(), imageLoader);
if(items.get(0).getName().contains("taksi"))
image.setDefaultImageResId(R.drawable.telefonas);
else
image.setDefaultImageResId(R.drawable.be_fono);
name.setText(i.getRealName());
type.setText(i.getType());
return convertView;
}
public List<Item> getItems(){
return items;
}
public Filter getFilter(final List<Item> all_items, final boolean deleted) {
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence charSequence) {
FilterResults results = new FilterResults();
if (charSequence == null || charSequence.length() == 0) {
results.values = items;
results.count = items.size();
} else {
List<Item> filtered_items = new ArrayList<Item>();
if(deleted)
items = all_items;
for (int i = 0; i < items.size(); i++) {
String modifiedName = items.get(i).getRealName().toLowerCase();
String modifiedQuery = charSequence.toString().toLowerCase();
modifiedName = encode_lithuanian(modifiedName);

}

}
return results;
}
#Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
items = (List<Item>) filterResults.values;
notifyDataSetChanged();
}
public int show_size(){
return items.size();
}
};
}
// What you'll do when you'll want to refresh (why not?)
#Override
public void refresh() {
}
// What you'll do when you'll want to search from SearchView
#Override
public void searchForText(String searchedText) {
}
// What you'll do when you'll want to have a look with another cool Object like a LatLong or some other stuff (optional, of course)
#Override
public void searchWithSomethingElse(Object SomethingElse) {

}
And then your Fragment will also change a bit but not as much as in the other solution:

Android displaying list using expandableListView

I have followed this example tutorial and developed a sample application http://www.androidhive.info/2013/07/android-expandable-list-view-tutorial/
If i click on Core i want to load one more list in the same Screen under Core,How Could i do this?using my below code i am able to load the child list in another Screen,help?
My Code for ChildClickListener goes here:
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
// TODO Auto-generated method stub
Log.d("onChildClick", "onChildClick");
String position = (String) parentItems.get(groupPosition);
Log.d("position", position);
String child = listDataChild.get(position).get(childPosition);
Log.d("child", child);
if (child.equalsIgnoreCase("Core")) {
ArrayList<String> parentItems = new ArrayList<String>();
HashMap<String, List<String>> listDataChild = new HashMap<String, List<String>>();
ArrayList<String> childItems = new ArrayList<String>();
childItems.add("corejava");
childItems.add("corejava");
childItems.add("corejava");
childItems.add("corejava");
parentItems.add(position);
listDataChild.put(parentItems.get(0), childItems);
expandableList = (ExpandableListView) findViewById(R.id.lvExp);
CoreAdapter adapter = new CoreAdapter(parentItems,
listDataChild);
CustExpListview SecondLevelexplv = new CustExpListview(
MainActivity.this);
adapter.setInflater(
(LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE),
MainActivity.this);
SecondLevelexplv.setAdapter(adapter);
SecondLevelexplv.setGroupIndicator(null);
expandableList.setAdapter(adapter);
}

i write one treeView adapter for you, you can use this and put many level as you want, for that you need just copy following code:
MainActivity:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// add data for test on one list<AccountHierarchical>
AccountHierarchical obj = new AccountHierarchical();
obj.setLevelId(1);
obj.setTitle("level 1");
AccountHierarchical obj2 = new AccountHierarchical();
obj2.setLevelId(1);
obj2.setTitle("level 2");
AccountHierarchical obj3 = new AccountHierarchical();
obj3.setLevelId(1);
obj3.setTitle("level 3");
List<AccountHierarchical> emptyList = new ArrayList<AccountHierarchical>();
obj3.setList(emptyList);
List<AccountHierarchical> list2 = new ArrayList<AccountHierarchical>();
list2.add(obj3);list2.add(obj3);list2.add(obj3);list2.add(obj3);list2.add(obj3);
obj2.setList(list2);
List<AccountHierarchical> list = new ArrayList<AccountHierarchical>();
list.add(obj2);list.add(obj2);list.add(obj2);list.add(obj2);list.add(obj2);
obj.setList(list);
List<AccountHierarchical> result = new ArrayList<AccountHierarchical>();
result.add(obj);result.add(obj);result.add(obj);result.add(obj);
// create Adapter
TreeView adapter = new TreeView(result, this,
getLayoutInflater() , false, 0);
ExpandableListView expandList = (ExpandableListView)findViewById(R.id.expandableList_tree);
expandList.setGroupIndicator(null);
expandList.setAdapter(adapter);
}
CustExpListview:
public class CustExpListview extends ExpandableListView {
int intGroupPosition, intChildPosition, intGroupid;
public CustExpListview(Context context) {
super(context);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// widthMeasureSpec = MeasureSpec.makeMeasureSpec(400,
// MeasureSpec.AT_MOST);
heightMeasureSpec = MeasureSpec.makeMeasureSpec(600,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
AccountHierarchical:
public class AccountHierarchical {
List<AccountHierarchical> list;
private String Title;

You have to create a layout in the xml file (from where your core textview comes from) and display an image view below
onClick of that imageView you will just have to make your layout Gone and Visible
I have just given you direction rest relies on your skill :)
<RelativeLayout
android:id="#+id/option"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:gravity="center"
android:orientation="horizontal" >

In Jave File
linear.setVisibility(View.GONE);
option.setOnClickListener(new OnClickListener() {

You need to switch to Three-Level of Expandable ListView which contains the subchild inside child.

Snap :
This is what it should look like.False items are checked in the snap
Above shows the full code of my project.
These are my requirements:
It is all about event planner for Food. The invited guests can select and save the interested food items such as pizza, Caesar salad, Ameretocokies etc from the items list and mail to the inviter so that the inviter can view the saved items and arrange for the selected items.

I picked the solution from Romain Guy's solution #
https://groups.google.com/forum/?fromgroups#!topic/android-developers/No0LrgJ6q2M
I have used a ViewHolder pattern for smooth scrolling and performance. I have used a SparseBooleanArray to get checked items.
I assume you want the items whose corresponding check boxes are checked.

Now 1 and 2 are checked and when you click the button at the bottom you see the selected text. I checked 1 and 2 manually. However it depends on the response ie True or False. Right now all veg items are true.
Note: The list displays only veg items

If you are using list-view and you want to check list-view item then you can use below code.
int len = mListView.getCount();
SparseBooleanArray checked = mListView.getCheckedItemPositions();
for (int i = 0; i < len; i++)
if (checked.get(i)){
..... // Your code whatever you want to do with selected item..
}
else{
....
}

How to get checkbox state in a gridview

i need to get the check-box state from a grid-view when clicking on a button
i tried many things but the state is always "false"
here is my code
this is the adapter

public static String u_id, ut_ = "";
Button send, cancel;
List<Items_FriendsRequest> SuggestFriendsItems;

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.displayphoto_from_album);
initialise_View();
here i need to get the values but its always false!!!!
send.setOnClickListener(new OnClickListener() {
#Override

// add the id of the ones that been checked . . to string with
// (,)

gridView.getItemAtPosition(i);
}

Use a Sparse Boolean Array

Check Romain Guy Solution. Use GridView instead of Listview.
Similar to the one answered here. Instead of listview use gridview.
in gridview checkbox is unchecked while scrolling gridview up and down
Heres' another example. Same use gridview instead of Listview

Snap shot

There is a lot of unecessary code in you question in my opinion (way better than too little, though), try change:
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int getPosition = (Integer) buttonView.getTag(); // Here we get the position that we have set for the checkbox using setTag.
// -- buttonView.isChecked() changed to isChecked -- //
items.get(getPosition).setSelected(isChecked); // Set the value of checkbox to maintain its state.
Log.v("Changed",items.get(getPosition).getId_()+"");
}
If that does not work please show clearly where you read the false value and expect true.
