I have a listview with a checkbox in a dialog. Now I need to get only the updated checkbox item from the dialog's 'ok click'. For example if the user checks only one checkbox in the row I need to get only that status, but if the user checks and unchecks the checkbox I don't want that status. I tried using a hash table to get and remove statuses when checked, but on listview scroll the checkbox event gets executed and hash table filled with the wrong values.
public class SelectGroupAdaptor extends BaseAdapter {
Activity activity;
ArrayList<SelectGroupItems> data = new ArrayList<>();
Hashtable<Integer,Boolean> status;
public SelectGroupAdaptor(Activity activity) {
this.activity = activity;
}
public void add(SelectGroupItems selectGroupItems) {
this.data.add(selectGroupItems);
notifyDataSetChanged();
status=new Hashtable<>();
}
public ArrayList<SelectGroupItems> getCheckedData () {
return data;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
TextView textView;
CheckBox checkBox;
if (convertView == null) {
convertView = LayoutInflater.from(activity).inflate(R.layout.layout_select_group_row, null);
}
textView = (TextView) convertView.findViewById(R.id.label);
textView.setTypeface(Util.setCustomFont(activity));
checkBox = (CheckBox) convertView.findViewById(R.id.checkbox);
textView.setText(data.get(position).getGroupName());
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
data.get(position).setChecked(isChecked);
if(status!=null)
{
if(status.get(position)!=null)
{
status.remove(position);
}else
{
status.put(position,isChecked);
}
}
}
});
checkBox.setChecked((data.get(position).isChecked()));
return convertView;
}
public Hashtable<Integer,Boolean> getStatus()
{
return status;
}
}
Can anyone help me
You don't need HashMap, a simple item holder class with a status property would help you. See your modified code:
Edit: If I understood you correctly, you want to get the SelectGroupItems object when its check status changed? If so see edited code below:
public class SelectGroupAdaptor extends BaseAdapter {
Activity activity;
ArrayList<SelectGroupItemHolder> data = new ArrayList<SelectGroupItemHolder>();
OnItemCheckStatusChangedListener onItemCheckStatusChangedListener;
// a item holder class, not a view holder
private static class SelectGroupItemHolder {
SelectGroupItems selectGroupItems;
boolean status;
}
public interface OnItemCheckStatusChangedListener {
public void onItemCheckStatusChanged(SelectGroupItems selectGroupItems, boolean checkStatus, int position);
}
public void setOnItemCheckStatusChangedListener(OnItemCheckStatusChangedListener onItemCheckStatusChangedListener) {
this.onItemCheckStatusChangedListener = onItemCheckStatusChangedListener;
}
public SelectGroupAdaptor(Activity activity) {
this.activity = activity;
}
public void add(SelectGroupItems selectGroupItems) {
SelectGroupItemHolder selectGroupItemHolder = new SelectGroupItemHolder();
selectGroupItemHolder.selectGroupItems = selectGroupItems;
this.data.add(selectGroupItemHolder);
notifyDataSetChanged();
}
public ArrayList<SelectGroupItems> getCheckedData() {
ArrayList<SelectGroupItems> checkedItemList = new ArrayList<SelectGroupItems>();
for (SelectGroupItemHolder selectGroupItemHolder : data) {
if (selectGroupItemHolder.status) {
checkedItemList.add(selectGroupItemHolder.selectGroupItems);
}
}
return checkedItemList;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
TextView textView;
CheckBox checkBox;
if (convertView == null) {
convertView = LayoutInflater.from(activity).inflate(R.layout.layout_select_group_row, null);
}
textView = (TextView) convertView.findViewById(R.id.label);
textView.setTypeface(Util.setCustomFont(activity));
checkBox = (CheckBox) convertView.findViewById(R.id.checkbox);
textView.setText(data.get(position).selectGroupItems.getGroupName());
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
data.get(position).status = isChecked;
if(onItemCheckStatusChangedListener != null) {
onItemCheckStatusChangedListener.onItemCheckStatusChanged(data.get(position).selectGroupItems, data.get(position).status, position);
}
}
});
checkBox.setChecked((data.get(position).status));
return convertView;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
}
Set the check status change listener of your selectGroupAdapter instance. ie:
selectGroupAdaptor.setOnItemCheckStatusChangedListener(new SelectGroupAdaptor.OnItemCheckStatusChangedListener() {
#Override
public void onItemCheckStatusChanged(SelectGroupItems selectGroupItems, boolean checkStatus, int position) {
// handle check status change
}
});

I have a recycler view, which consists of edittext and buttons for each view. I would like to have functionality in such a way that if I enter some text or attach an image for a view, then some of the buttons' functionality needs to be disabled in that view as soon as I click the button.
With the below code, I can attach images when ProofClick function is called via the interface, and then I set the button as disabled for the same position, but the button is not disabled, and I can attach images to the same view twice, which I do not want.
Adapter class:
// Check if the button is clicked and disable
private boolean clicked = false;
public InsStepsContentAdapter(List<InspectonScroll> scrollList,
ClickOnRecycle clickOnRecycle, String[] options) {
this.scrollList = scrollList;
this.clickOnRecycle = clickOnRecycle;
this.options = options;

}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.setIsRecyclable(false);
holder.progressbar.setMax(scrollList.size());
holder.title.setText(scrollList.get(position).getSteps().get(position).getTitle());
holder.btnAttach.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(clicked){
clicked = true;
clickOnRecycle.ProofClick(holder.getAdapterPosition());
holder.btnAttach.setEnabled(true);
} else{

}
}
});

one thing can be done here is maintaining the state of the button in the model as shown in the example and by using that state we can enable or disable the button in the onBindViewHolder method .
I want to highlight the selected items in recyclerview. I can count the number of items selected.

if (btn.getBackground().getConstantState().equals(itemView.getResources().getDrawable(R.drawable.understand_clicked).getConstantState())) {

} else {
btn.setBackground(itemView.getResources().getDrawable(R.drawable.understand_clicked));
}
Do this code in a custom recyclerviewadapter, in View holder class. Use getConstantState for current state of image. You can also change color of selected raw.
you can use use below code
public void onBindViewHolder(final ViewHolder holder, final int position) {
holder.textView.setText(array[position]);
holder.row_linearlayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
index=position;
notifyDataSetChanged();
}
});
if(index==position){
holder.layout.setBackgroundColor(Color.parseColor("#ff8569"));
holder.textView.setTextColor(Color.parseColor("#ffffff"));
}
else
{
holder.layout.setBackgroundColor(Color.parseColor("#ffffff"));
holder.textView.setTextColor(Color.parseColor("#000000"));
}
}

I'm making NLevel expandable list using listview. I've added checkbox only last level data in list view. I have stuck in below scenario.
If I check checkbox then when I expand listview means checkbox gets automatically unchecked.I don't want it to be like that. If I checked checkbox it should stay checked until I uncheck manually.

Thanks in advance!!
i think you need to store the checkbox state in a boolean (is checked), and reflect that on the view, when getView() is called.
1- Add boolean checked to NLevelItem :
private boolean checked = false;
//add setter: setChecked(boolean)
//add getter isChecked()
2- Use that boolean in getView() (last one where checkbox is added)
#Override
public View getView(final NLevelItem item) {
// .......
final CheckBox checkBox = (CheckBox)view.findViewById(R.id.check);
checkBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//store checkbox state, note that NLevelItem item might need to be defined with 'final'
item.setChecked(checkBox.isChecked());
if(checkBox.isChecked()){
tempList.add((String) ((SomeObject)childs.getWrappedObject()).getName()+"+"+name);
}
else {
tempList.remove((String) ((SomeObject)childs.getWrappedObject()).getName()+"+"+name);
}
}//onClick()
}//setOnClickListener()
//update checkbox state from the corresponding NLevelItem
checkBox.setChecked(item.isChecked());
//.......
}//getView()
-EDIT:
to select 1 item, you need to iterate all items, set checked = false, but 1
i am not sure if you have to do it on:
List<NLevelItem> list;
or
List<NLevelListItem> filtered;
in the adapter class
private void selectOnly(int position){
for(int a=0;a<list.size();a++){
if(a == position){
list.get(a).setChecked(true);
continue;
}
list.get(a).setChecked(false);
}//for loop
notifyDataSetChanged(); // to update views (checkbox state)
}
Usage: selectOnly(15);
Use ViewHolder class to set and get Tag like this:
public class ListAdapter extends BaseAdapter {
private Context con;
private List<String> dataLt;
private static LayoutInflater inflater = null;
public ListAdapter(Context context, List<String> dataList){
con = context;
dataLt = dataList;
inflater = (LayoutInflater)con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return dataLt.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
ViewHolder holder;
if(convertView==null){
/****** Inflate tabitem.xml file for each row ( Defined below ) *******/
vi = inflater.inflate(R.layout.list_item_search, null);
/****** View Holder Object to contain tabitem.xml file elements ******/
holder = new ViewHolder();
holder.textView = (TextView) vi.findViewById(R.id.textView);
/************ Set holder with LayoutInflater ************/
vi.setTag( holder );
}
else
holder=(ViewHolder)vi.getTag();
return vi;
}
public static class ViewHolder{
TextView textView;
}
}
Hope this may help.

I'm using a custom adapter to load 20 items from a JSON string as well as implement ads in the 4th and 14th position. What I'm encountering is that when I scroll to view item #19, it crashes with the error in the title.
I know that the error is saying that it's trying to access an index that is not in the array but I think it's because it's included the adViews in the index (which it shouldn't). I feel like this is something simple that I am missing but please help. Here are my 2 adapters:
public class ListViewAdapter extends BaseAdapter implements AdListener {
private final Activity activity;
private final BaseAdapter delegate;
public ListViewAdapter(Activity activity, BaseAdapter delegate) {
this.activity = activity;
this.delegate = delegate;
}
#Override
public int getCount() {
// Total count includes list items and ads.
return delegate.getCount() + 2;
}
#Override
public Object getItem(int position) {
// Return null if an item is an ad. Otherwise return the delegate item.
if (isItemAnAd(position)) {
return null;
}
return delegate.getItem(position - 1);

// Total count includes list items and ads.
return delegate.getCount() + 2;
}
you should return the size of the dataset without changing it. If you need to show more items, add those to the dataset. Changing it with
#Override
public int getCount() {
// Total count includes list items and ads.
return delegate.getCount() ;
}
Should fix your exception.
Edit, in getView you should avoid tampering the position android is providing you:
position+1
