Multi selection spinner in android without AlertDialog

Multi selection spinner in android without AlertDialog - android

i want the same as this link https://www.gorecess.com/ first spinner . multi selection spinner in android with checkbox .Show the spinner in dropdown. anyone know answer...

multi select spinner :
1- create a spinner in your own xml ,like this
<Spinner
android:id="#+id/mySpinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginTop="1dp"/>
2-create a custom dapter for spinner like this :
public class AdapterTagSpinnerItem extends ArrayAdapter<TagListSimpleSearch>
{
private LayoutInflater mInflater;
private List<TagListSimpleSearch> listState;
public Spinner mySpinner = null;
public AdapterTagSpinnerItem(Context context, int resource, List<TagListSimpleSearch> objects, Spinner mySpinner)
{
super(context, resource, objects);
this.listState = objects;
this.mySpinner = mySpinner;
mInflater = LayoutInflater.from(context);
}
#Override
public View getDropDownView(int position, View convertView, ViewGroup parent)
{
return getCustomView(position, convertView, parent);
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
return getCustomView(position, convertView, parent);
}
public View getCustomView(final int position, View convertView, ViewGroup parent)
{
String text = "";
final ViewHolder holder;
if (convertView == null)
{
holder = new ViewHolder();
mInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.spinner_item, null, false);
holder.mTextView = convertView.findViewById(R.id.tvSpinnerItem);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
/**
* check position , if position is zero we put space on top of list of spinner
*/
if ((position == 0))
text = oneSpace;
/**
* check position , if position is one we put cross mark before text to show that position used to be for clear all selected items on spinner
*/
else if ((position == 1))
text = " " + String.valueOf((char) crossMarkAroundBox) + " " + listState.get(position).getTagText();
/**
* check position , if position is two we put check mark before text to show that position used to be for select all items on spinner
*/
else if ((position == 2))
text = " " + String.valueOf((char) tikMarkAroundBox) + " " + listState.get(position).getTagText();
/**
* check position , if position is bigger than two we have to check that position is selected before or not and put check mark or dash before text
*/
else
{
if (listState.get(position).isSelected())
{
text = " " + String.valueOf((char) tikMark) + " " + listState.get(position).getTagText();
}
else
{
text = " " + String.valueOf(dash) + " " + listState.get(position).getTagText();
}
}
holder.mTextView.setText(text);
holder.mTextView.setTag(position);
holder.mTextView.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
/**
* if you want open spinner after click on text for first time we have to open spinner programmatically
*/
mySpinner.performClick();
int getPosition = (Integer) v.getTag();
listState.get(getPosition).setSelected(!listState.get(getPosition).isSelected());
notifyDataSetChanged();
/**
* if clicked position is one
* that means you want clear all select item in list
*/
if (getPosition == 1)
{
clearList();
}
/**
* if clicked position is two
* that means you want select all item in list
*/
else if (getPosition == 2)
{
fillList();
}
}
});
return convertView;
}
/**
* clear all items in list
*/
public void clearList()
{
for (TagListSimpleSearch items : listState)
{
items.setSelected(false);
}
notifyDataSetChanged();
}
/**
* select all items in list
*/
public void fillList()
{
for (TagListSimpleSearch items : listState)
{
items.setSelected(true);
}
notifyDataSetChanged();
}
/**
* view holder
*/
private class ViewHolder
{
private TextView mTextView;
}
}
3- now you have to create object for adapter
public class TagListSimpleSearch {
private String TagId;
private String TagText;
private boolean selected;
public String getTagId() {
return TagId;
}
public void setTagId(String TagId) {
this.TagId = TagId;
}
public String getTagText() {
return TagText;
}
public void setTagText(String tagText) {
TagText = tagText;
}
public boolean isSelected()
{
return selected;
}
public void setSelected(boolean selected)
{
this.selected = selected;
}
}
4-fill spinner adapter in your activity
public static String oneSpace =" ";
public static int tikMark =0X2714;
public static int crossMark =0X2715;
public static int tikMarkAroundBox =0X2611;
public static int crossMarkAroundBox =0X274E;
public static String dash ="-";
private Spinner mySpinner;
mySpinner= (Spinner) findViewById(R.id.mySpinner);
List<TagListSimpleSearch> tagsNames = new ArrayList<>();
TagListSimpleSearch tagSpecific=new TagListSimpleSearch();
tagSpecific.setTagId("0");
tagSpecific.setTagText(oneSpace);
tagsNames.add(tagSpecific);
tagSpecific=new TagListSimpleSearch();
tagSpecific.setTagId("1");
tagSpecific.setTagText("select All Items");
tagsNames.add(tagSpecific);
tagSpecific=new TagListSimpleSearch();
tagSpecific.setTagId("2");
tagSpecific.setTagText("remove All Items");
tagsNames.add(tagSpecific);
tagSpecific=new TagListSimpleSearch();
tagSpecific.setTagId("0");
tagSpecific.setTagText("Item 0");
tagsNames.add(tagSpecific);
tagSpecific=new TagListSimpleSearch();
tagSpecific.setTagId("1");
tagSpecific.setTagText("Item 1");
tagsNames.add(tagSpecific);
tagSpecific=new TagListSimpleSearch();
tagSpecific.setTagId("2");
tagSpecific.setTagText("Item 2");
tagsNames.add(tagSpecific);
tagSpecific=new TagListSimpleSearch();
tagSpecific.setTagId("3");
tagSpecific.setTagText("Item 3");
tagsNames.add(tagSpecific);
final AdapterTagSpinnerItem adapterTagSpinnerItem = new AdapterTagSpinnerItem(this, 0, tagsNames,mySpinner);
mySpinner.setAdapter(adapterTagSpinnerItem);

<com.extra.MultiSelectionSpinner
android:id="#+id/input1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="2dp" />
MultiSelectionSpinner spinner=(MultiSelectionSpinner)findViewById(R.id.input1);
List<String> list = new ArrayList<String>();
list.add("List1");
list.add("List2");
spinner.setItems(list);

I have implemented a multiple selection spinner in android using AlertDialog
check the following code
public void classesSelect(){
regclassvalue.setText("");
AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);
builder.setTitle("Select Services");
final int array[] = new int[serarray.length];
check = new boolean[serarray.length];
for (int k = 0; k < serarray.length; k++) {
check[k] = false;
}
final List<String> classlist = Arrays.asList(serarray);
final List<Integer> classidlist = Arrays.asList(classidarray);
// this is the main part here we set the multichoice listener using serarray and check
builder.setMultiChoiceItems(serarray, check, new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
check[which] = isChecked;
}
});
builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
regclassvalue.setText("");
classids = "";
int io = 0;
for (int ii = 0; ii < check.length; ii++) {
boolean checked = check[ii];
if (checked) {
array[io] = ii;
io++;
}
}
for (int k = 0; k < io; k++) {
if (io == 1) {
classids = classids + classidlist.get(array[k]);
regclassvalue.setText(regclassvalue.getText() + classlist.get(array[k]));
} else if (k == io - 1) {
classids = classids + classidlist.get(array[k]);
regclassvalue.setText(regclassvalue.getText() + classlist.get(array[k]));
} else {
classids = classids + classidlist.get(array[k]) + ",";
regclassvalue.setText(regclassvalue.getText() + classlist.get(array[k]) + " ,");
}
}
//Toast.makeText(RegisterActivity.this,classids,Toast.LENGTH_LONG).show();
}
});
builder.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}

You need to follow viewholder pattern. It will resolve your issue. You can check it here https://developer.android.com/training/improving-layouts/smooth-scrolling.html

The only place you're keeping count is in the view. You should make your count a field in the list item ShowProducts and create a getter & setter. For example, in the plus onClickListener, instead of
int a = Integer.parseInt(tvQunatitySetOfSelectedItem.getText().toString());
a++;
You'll have
// for example, in the `plus` listener
int a = showProducts.getCount();
a++;
showProducts.setCount(a);
And don't forget
notifyDataSetChanged();

How to use getPosition() to get the ListView value?

In Activity WorkDetailsTable , it has a ListView as shown below. When it is clicked, it should display the value on the Add_Details_Information EditText
Assume the first list is clicked, and it intent to Add_Details_Information
Noted that the value on editText was actually get from the second list in Activity A. But what I want is get value accordingly to their position not the latest value.
WorkDetailsTable
int mClickedPosition;
MyCustomBaseAdapter objMyCustomBaseAdapter;
ArrayList<SearchResults> results=new ArrayList<SearchResults>();
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() { // if listView is clicked
#Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
mClickedPosition = position;
// how to getPosition???
Intent i = new Intent(getApplication(), Add_Details_Information.class);
i.putExtra("ReceiveProject", ReceiveProject);
i.putExtra("ReceiveDescription", ReceiveDescription);
i.putExtra("ReceiveProgress", ReceiveProgress);
i.putExtra("ReceiveTimeIn", ReceiveTimeIn);
i.putExtra("ReceiveTimeOut", ReceiveTimeOut);
i.putExtra("date",date);
i.putExtra("status", status);
startActivityForResult(i,PROJECT_REQUEST_CODE);
}
});
}
Add_Details_Information
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.add_details_information);
addItemsOnSpinner(); // Spinner for project/service/training
tp = new TimePick(); // call tmePick
description=(EditText)findViewById(R.id.editTextWorkDescription);
timeIn=(EditText)findViewById(R.id.TimeIn);
timeOut=(EditText)findViewById(R.id.TimeOut);
save=(Button)findViewById(R.id.saveButton);
seekBar=(SeekBar)findViewById(R.id.seekBarPercentage);
progressText=(TextView)findViewById(R.id.textProgress);
progressText.setText("Covered:" + "" + seekBar.getProgress() + "/" + seekBar.getMax());
if(getIntent().getExtras()!=null)
{
final String Project1=getIntent().getStringExtra("ReceiveProject");
final String Description1=getIntent().getStringExtra("ReceiveDescription");
final int Progress1=getIntent().getIntExtra("ReceiveProgress", 0);
final String TimeIn1=getIntent().getStringExtra("ReceiveTimeIn");
final String TimeOut1=getIntent().getStringExtra("ReceiveTimeOut");
// project.setText(Project1);
description.setText(Description1);
seekBar.setProgress(Progress1);
timeIn.setText(TimeIn1);
timeOut.setText(TimeOut1);
seekBar.setProgress(Progress1);
progressText.setText("Covered:" + "" + seekBar.getProgress() + "/" + seekBar.getMax());
}
MyCustomBaseAdapter
public class MyCustomBaseAdapter extends BaseAdapter{ // for ListView in WorkDetailsTable
private static ArrayList<SearchResults> searchArrayList;
private LayoutInflater mInflater;
public MyCustomBaseAdapter(Context context, ArrayList<SearchResults> results) {
searchArrayList = results;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return searchArrayList.size();
}
public Object getItem(int position) {
return searchArrayList.get(position);
}
public long getItemId(int position) {
return position;
}
public void addNewItem(String P,String D,int Per,String I,String O)
{
SearchResults obj=new SearchResults();
obj.setProject(" Project/Service/Training : "+P);
obj.setDescription(" Work Description : " + D);
obj.setProgress(" Progress : " + Per);
obj.setTimeIn(" Time In : " + I);
obj.setTimeOut(" Time Out : " + O);
searchArrayList.add(obj);
this. notifyDataSetChanged();
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.custom_row_view, null);
holder = new ViewHolder();
holder.txtProject= (TextView) convertView.findViewById(R.id.ListProject);
holder.txtDescription = (TextView) convertView.findViewById(R.id.ListDescription);
holder.txtProgress = (TextView) convertView.findViewById(R.id.ListProgress);
holder.txtIn=(TextView)convertView.findViewById(R.id.ListTimeIn);
holder.txtOut=(TextView)convertView.findViewById(R.id.ListTimeOut);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txtProject.setText(searchArrayList.get(position).getProject());
holder.txtDescription.setText(searchArrayList.get(position).getDescription());
holder.txtProgress.setText(searchArrayList.get(position).getProgress());
holder.txtIn.setText(searchArrayList.get(position).getTimeIn());
holder.txtOut.setText(searchArrayList.get(position).getTimeOut());
return convertView;
}
static class ViewHolder {
TextView txtProject;
TextView txtDescription;
TextView txtProgress;
TextView txtIn;
TextView txtOut;
}
}
Trying Code
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() { // if listView is clicked
#Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
Object o=listview.getItemAtPosition(position);
SearchResults fullObject=(SearchResults)o;
String ReceiveDescription=((SearchResults) o).getDescription();
Intent i = new Intent(getApplication(), Add_Details_Information.class);
i.putExtra("ReceiveDescription", ReceiveDescription);
startActivityForResult(i,PROJECT_REQUEST_CODE);
}
});
}

Try this:
public View getViewByPosition(int pos, ListView listView) {
final int firstListItemPosition = listView.getFirstVisiblePosition();
final int lastListItemPosition = firstListItemPosition + listView.getChildCount() - 1;
if (pos < firstListItemPosition || pos > lastListItemPosition ) {
return listView.getAdapter().getView(pos, null, listView);
} else {
final int childIndex = pos - firstListItemPosition;
return listView.getChildAt(childIndex);
}
}

OnClickListener in listview item always takes the last row

I download data from server and fill the listview with them. Every item in the listview has 3 buttons, on every button I would like to make an onclicklistener. When the user clicks one of the buttons, It should for example open the new activity. Every row (object) has some id, and when I click on some of these buttons, the id is always for example 15 (it is always the id of the last row in listview).
I have tried to declare the OnClickListeners with many different ways, the result was the same.

Example: I click on the btnMakeComment in first row, the new Activity opens and download from db comments of the object with id 15. Then I click on the btnMakeComment in the third row and the new Activity opens and download from db comments of the object with the same id, like last time (again 15).
But in the ListView are not the same rows/objects, they are differentm just on click it seems like they would be the same.

Your are getting last id/ last row position every time because last view reders at last
To get row position on button click you can set postion as tags to your buttons and check that tags in onclickListner
For example in your getview() method put position as tag in viewHolder.btnMakeComment button
viewHolder.btnMakeComment.setTag(position); and in OnClickListner Check tag
int position = (int)v.getTag();

Change your adapter:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.law_item, parent, false);
this.convertView = convertView;
viewHolder = new ViewHolder();
viewHolder.tvName = (TextView) convertView.findViewById(R.id.lawItemName);
viewHolder.tvDescription = (TextView) convertView.findViewById(R.id.lawItemDescription);
viewHolder.tvStatus = (TextView) convertView.findViewById(R.id.lawItemStatus);
viewHolder.btnDownvote = (Button) convertView.findViewById(R.id.lawItemDownvote);
viewHolder.btnUpvote = (Button) convertView.findViewById(R.id.lawItemUpvote);
viewHolder.btnMakeComment = (Button) convertView.findViewById(R.id.lawItemMakeComment);
convertView.setTag(viewHolder);
}
else {
viewHolder = (ViewHolder) convertView.getTag();
Log.d("View holder", "get tag");
}
viewHolder.currentLaw = getItem(position);
Log.d("View holder", "new one");
Log.d("LAW ID, ADAPTER", String.valueOf(viewHolder.currentLaw.getId()));
viewHolder.tvName.setText(viewHolder.currentLaw.getName());
viewHolder.tvDescription.setText(viewHolder.currentLaw.getDescription());
viewHolder.tvStatus.setText(viewHolder.currentLaw.getStateValue());
setSurfacesColors();
viewHolder.btnMakeComment.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//position -> get id
//action
}
})
viewHolder.btnDownvote.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//position -> get id
//action
}
});
viewHolder.btnUpvote.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//position -> get id
//action
}
});
disableIfVoted();
return convertView;
}

try this bt i am not sure:
ArrayList<String> Ex=new ArrayList<String>();
for (int i = 0 ; i<youriDvalue.length; i++)
{
Ex.add(currentVerse_speak.get(i));
//(or)
String []ex1;
ex1=currentVerse_speak.get(i)+"~";
exi[i]=currentVerse_speak.get(i).toString();
}
txtview.settext(Ex.toString());
txtview.settext(ex1.tosting());

Spinners selection changes on adding new items or scrolling listview android

This is because of view recycling. View are recycled with the last state. If your spinner had something selected, and if that view is reused it'll also pick the state of the spinner. You need to add logic to preserve state of your Spinners. You can maintain a dictionary with row position and selectedIndex.
//Class level field
Map<Integer, Integer> myMap = new HashMap<Integer, Integer>();
inside your getView() method check if we have a state saved for the spinner at this row psition
if (myMap.containsKey(position)) {
spinner.setSelection(myMap.get(position));
}
Saving state when an item is selected in spinner
#Override
public void onItemSelected(AdapterView<?> parentView, View v, int selectedIndex, long id) {
//...
myMap.put(position, selectedIndex);
//...
}

Automatically check the checkbox that corresponds to the value from the database

I am using a baseadapter for my customize spinner with checkbox that allow the user to choose multiple values. I have an update button in my application, and I need to set the values from the database as true in the checkbox. My problem is I don't know how to do it. For example I have ["A","B","C","D"] values in my spinner, in my database I got B and D. How will i automatically check that values when I open the activity.
Here is my code that populate my customize spinner
private void initializeCustomerSegment() {

selected += consumerSegments.get(i);
selected += ", ";
flag = 1;
}
}
if(flag == 1) {
tv_ConsumerSegment.setText(selected);
}
expandedConsumerSegment =true;
} else {
//display shortened representation of selected values
tv_ConsumerSegment.setText(BrandListAdapter.getSelected());
expandedConsumerSegment = false;
}
}
});

I think You need to manage another storage for selected / unselected items and move it to the adapter. E.g. it can be HashSet<String>. Then code would look the following (note, that I made it compilable, because it's impossible to compile one provided in the question):
public class S_10th_IReportMain extends Activity {
boolean expandedConsumerSegment;
ConsumerSegmentListAdapter mAdapter;
private static class DatabaseHandler {
List<String> setItemOnConsumerSeg() {
return Collections.emptyList();
}
}
private static class BrandListAdapter {
static String getSelected() {
return "string";
}
}
DatabaseHandler databaseHandler = new DatabaseHandler();
private void initializeCustomerSegment() {
final ArrayList<String> consumerSegments = new ArrayList<String>();
List<String> consumerSegment = databaseHandler.setItemOnConsumerSeg();
consumerSegments.addAll(consumerSegment);
final TextView tv_ConsumerSegment = (TextView) findViewById(R.id.tv_ConsumerSegment);
tv_ConsumerSegment.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!expandedConsumerSegment) {
// display all selected values
String selected = "";
int flag = 0;
for (String segment : consumerSegments) {
if (mAdapter.isChecked(segment)) {
selected += segment;
selected += ", ";
flag = 1;
}
}
if(flag == 1) {
tv_ConsumerSegment.setText(selected);
}
expandedConsumerSegment =true;
} else {
//display shortened representation of selected values
tv_ConsumerSegment.setText(BrandListAdapter.getSelected());
expandedConsumerSegment = false;
}
}
});
//onClickListener to initiate the dropDown list
TextView tv_customerSegment = (TextView)findViewById(R.id.tv_ConsumerSegment);
tv_customerSegment.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
initiatePopUpCustomerSegment(consumerSegments,tv_ConsumerSegment);
}
});
}
PopupWindow pwConsumerSegment;
private void initiatePopUpCustomerSegment(ArrayList<String> customerSegments, TextView tv_CustomerSegment) {
LayoutInflater inflater = (LayoutInflater)S_10th_IReportMain.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//get the pop-up window i.e. drop-down layout
LinearLayout layoutCustomerSegment = (LinearLayout)inflater.inflate(R.layout.pop_up_window_customersegment, (ViewGroup)findViewById(R.id.PopUpView1));
//get the view to which drop-down layout is to be anchored
RelativeLayout layout4 = (RelativeLayout)findViewById(R.id.relativeLayout4);
pwConsumerSegment = new PopupWindow(layoutCustomerSegment, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
//Pop-up window background cannot be null if we want the pop-up to listen touch events outside its window
pwConsumerSegment.setBackgroundDrawable(new BitmapDrawable());
pwConsumerSegment.setTouchable(true);
//let pop-up be informed about touch events outside its window. This should be done before setting the content of pop-up
pwConsumerSegment.setOutsideTouchable(true);
pwConsumerSegment.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
//dismiss the pop-up i.e. drop-down when touched anywhere outside the pop-up
pwConsumerSegment.setTouchInterceptor(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
pwConsumerSegment.dismiss();
return true;
}
return false;
}
});
//provide the source layout for drop-down
pwConsumerSegment.setContentView(layoutCustomerSegment);
//anchor the drop-down to bottom-left corner of 'layout1'
pwConsumerSegment.showAsDropDown(layout4);
//populate the drop-down list
final ListView listCustomerSegment = (ListView) layoutCustomerSegment.findViewById(R.id.dropDownCustomerSegment);
ConsumerSegmentListAdapter adapter = new ConsumerSegmentListAdapter(this, customerSegments, tv_CustomerSegment);
listCustomerSegment.setAdapter(adapter);
}
public static class ConsumerSegmentListAdapter extends BaseAdapter {
private ArrayList<String> mListCustomerSegment;
private LayoutInflater mInflater;
private TextView mSelectedItems;
private static int selectedCount = 0;
private static String firstSelected = "";
private ViewHolder holder;
private static String selected = ""; //shortened selected values representation
private HashSet<String> mCheckedItems;
public static String getSelected() {
return selected;
}
public void setSelected(String selected) {
ConsumerSegmentListAdapter.selected = selected;
}
public ConsumerSegmentListAdapter(Context context, ArrayList<String> customerSegment,
TextView tv) {
mListCustomerSegment = new ArrayList<String>();
mListCustomerSegment.addAll(customerSegment);
mInflater = LayoutInflater.from(context);
mSelectedItems = tv;
}
/**
* Should be called then new data obtained from DB
*
* #param checkedItems array of strings obtained from DB
*/
public void setCheckedItems(final String[] checkedItems) {
mCheckedItems.clear();
Collections.addAll(mCheckedItems, checkedItems);
notifyDataSetChanged();
}
#Override
public int getCount() {
return mListCustomerSegment.size();
}
#Override
public Object getItem(int arg0) {
return null;
}
#Override
public long getItemId(int arg0) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.drop_down_customersegment, null);
holder = new ViewHolder();
holder.tv = (TextView) convertView.findViewById(R.id.SelectOptionCustomerSegment);
holder.chkbox = (CheckBox) convertView.findViewById(R.id.checkboxCustomerSegment);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
final String text = mListCustomerSegment.get(position);
final boolean checked = isChecked(text);
holder.tv.setText(mListCustomerSegment.get(position));
//whenever the checkbox is clicked the selected values textview is updated with new selected values
holder.chkbox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setText(position, checked, text);
}
});
if(checked) {
holder.chkbox.setChecked(true);
} else {
holder.chkbox.setChecked(false);
}
return convertView;
}
/*

private void setText(int position, boolean checked, String text){
if (!checked) {
mCheckedItems.add(text);
selectedCount++;
} else {
mCheckedItems.remove(text);
selectedCount--;
}
if (selectedCount == 0) {
mSelectedItems.setText(R.string.select_consumersegment);
} else if (selectedCount == 1) {
firstSelected = mCheckedItems.iterator().next();
mSelectedItems.setText(firstSelected);
setSelected(firstSelected);
} else if (selectedCount > 1) {
firstSelected = mCheckedItems.iterator().next();
mSelectedItems.setText(firstSelected + " & "+ (selectedCount - 1) + " more");
setSelected(firstSelected + " & "+ (selectedCount - 1) + " more");
}
}
/**
* #param segment to be checked
*
* #return true if the segment is checked
*/
public boolean isChecked(final String segment) {
return mCheckedItems.contains(segment);
}
private class ViewHolder {
TextView tv;
CheckBox chkbox;
}
}
}
So, then You obtain new data from database which should be checked You can just call mAdapter.setCheckedItems().

I already make it. By this:
for (int j=0; j<brands.size(); j++)
{
for(String chosenElement : Brands)
{
int index = brands.indexOf(chosenElement);
checkSelected[index] = true;
}
}
What I did is i look for the index of my chosen arraylist to my spinner's adapter and set the the checkbox index into true. That simple. Anyway thanks for the idea.
