I have displayed all the contacts within the phone along with a check box in a list view. Now when the user checks say A and B and clicks on "ok" button, then what I want is to display the list again when making all the check box checked value to false. For that, I have created a method but when I call this method the value of the selected contacts is set to unchecked only when the list is scrolled, else it remains unchecked.
Whats the problem with my code???
Code
public void getContactSync(Context context, ArrayList<ContactModel> data) {
setListAdapter(null);
contactListAdapter = new ContactListAdapter(context, data);
setListAdapter(contactListAdapter);
// contactListAdapter.notifyDataSetChanged();
}
On OK button click
Arrays.fill(ContactListAdapter.contacts, 0);
contactListFragment.getContactSync(getActivity(), dbHandler.getAlGetContacts());
Custom Adapter
public class ContactListAdapter extends BaseAdapter {
private Context context;
private ArrayList<ContactModel> data;

public static int[] contacts;

public static ArrayList<String> contactsId;
public ContactListAdapter(Context context, ArrayList<ContactModel> data) {
this.context = context;

private class ViewHolder {

on click of checkbox inside adapter just call notifydatasetchanged() it will solve your problem
holder.checkBox
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton,
boolean b) {
if (compoundButton == holder.checkBox) {
if (b) {
contacts[i] = 1;
// dbHandler.updateContactList(data.get(i).getUserID(),
// 1);
//
notifyDataSetChanged();
} else {
contacts[i] = 0;
notifyDataSetChanged();
}
}
}
}
);
if you want to refresh adapter on ok button click add this to ok button click
adapter.notifydatasetchagned()
Try to call setListAdapter(contactListAdapter); again inside your onClick()

I have a fragment with a listView.
The view is populated from a remote received JSON array as follows:
private void callVolley(){
SharedPreferences prefs3 =
getActivity().getSharedPreferences(MIEXAMEN, Context.MODE_PRIVATE);
final String id_materia= "42";
final String num_examen= "787878";
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage("Cargando temas de la materia seleccionada...");
showDialog();
JsonArrayRequest jArr = new JsonArrayRequest(url+"?id="+id_materia, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hideDialog();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Data item = new Data();
item.setMenu(obj.getString(TAG_NOMBRE));
item.setId(obj.getString(TAG_ID));
itemList.add(item);
} catch (JSONException e) {
e.printStackTrace();
}
}
// list.invalidateViews();
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hideDialog();
}
});
AppController.getInstance().addToRequestQueue(jArr);
}
Then I add programmatically a checkbox to each list item.
This is the adapter:
public class Adapter extends BaseAdapter {
private Context activity;
private ArrayList<Data> data;
private static LayoutInflater inflater = null;
private View vi;
private ViewHolder viewHolder;
public Adapter(Context context, ArrayList<Data> items) {
this.activity = context;
this.data = items;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int i) {
return i;
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int position, View view, ViewGroup viewGroup) {
vi = view;
final int pos = position;
Data items = data.get(pos);
if(view == null) {
vi = inflater.inflate(R.layout.list_row, null);
viewHolder = new ViewHolder();
viewHolder.checkBox = (CheckBox) vi.findViewById(R.id.cb);
viewHolder.menu = (TextView) vi.findViewById(R.id.nama_menu);
vi.setTag(viewHolder);
}else {
viewHolder = (ViewHolder) view.getTag();
}
viewHolder.menu.setText(items.getMenu());
if(items.isCheckbox()){
viewHolder.checkBox.setChecked(true);
} else {
viewHolder.checkBox.setChecked(false);
}
return vi;
}
public ArrayList<Data> getAllData(){
return data;
}
public void setCheckBox(int position){
Data items = data.get(position);
items.setCheckbox(!items.isCheckbox());
notifyDataSetChanged();
}
public class ViewHolder{
TextView menu;
CheckBox checkBox;
}
}
At start I need all checkboxes to be checked.
Then the user can check/uncheck the desired items.
On the fragment there is a button that reads all items checkbox states.
What should I implement to put all items in status checked so that on button clicked all items are recognized as checked?
This is a screenshot at start with all items unchecked:
EDIT
Code for the button onClickListener in the fragment:
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
checkbox = "";
checkbox_id = "";
for (Data hold : adapter.getAllData()) {
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getMenu();
checkbox_id += hold.getId()+",";
}
}
if (!checkbox.isEmpty()) {
dipilih = checkbox;
String preguntas = checkbox_id;
mPref = getActivity().getSharedPreferences(MIEXAMEN, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = mPref.edit();
editor.putString("preguntas_numero_string",preguntas);
editor.putString("preguntas_string",dipilih);
Log.d("seleccion","seleccion preguntas "+preguntas);
Log.d("seleccion","seleccion dipilih "+dipilih);
editor.apply();
} else {
dipilih = "No has seleccionado ningún tema.";
}
formSubmit(dipilih);
}
});
Do the following changes:
When you are adding Data to the list of Data.
Data item = new Data();
item.setMenu(obj.getString(TAG_NOMBRE));
item.setId(obj.getString(TAG_ID));
item.setCheckbox(true)
itemList.add(item);
This will initially make the checkbox checked.
Edit:
Update your xml layout. in your CheckBox put this attribute.
android:clickable="false"
Update your list setOnItemClickListener
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
adapter.setCheckBox(position);
}
});
Try replacing with the below code
viewHolder.checkBox.setChecked(true);
instead of
if(items.isCheckbox()){
viewHolder.checkBox.setChecked(true);
} else {
viewHolder.checkBox.setChecked(false);
}
Use this. It should work. -
Initially this -
viewHolder.checkBox.setChecked(true);
Then
viewHolder.checkBox.setOnCheckedChangeListener(new
CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton
buttonView,boolean isChecked) {
if(isChecked){
viewHolder.checkBox.setChecked(true);
} else {
viewHolder.checkBox.setChecked(false);
}
}
}
);
I'm fetching phone contacts using listview with checkboxes. I used the instrucstions given in this link. The code is working perfectly if I want to select some of the contacts. Now I want to add a "Select All" checkbox in the activity

There are a two issues there:
You're iterating over the entire list of contacts, instead of over the list of selected contacts only:
(I've also changed your iterator from a for-loop, to an array-iterator, this makes the code more readable)
In the unselect block, you're calling addContact instead of removeContact
Array<Contact> selectedContactsArray = contactsListAdapter.selectedContactsList.contactArrayList;
for (Contact contact : selectedContactsArray) {
contactsListAdapter.selectedContactsList.removeContact(contact);
}
I am able to load data from database into my custom ListView, but not able to display the item(relevant, courseName to be precise) when the checkbox is checked(multiple checkboxes can be checked) on toast when I press button.

if (p.getCourseSelected()){
result += "\n" + p.getCourseName();
}
}
Toast.makeText(this, result+"\n",Toast.LENGTH_LONG).show();
}
}//end class
Please guide me through this.
First, add a setter method in CourseDisplay class
public boolean setCourseSelected(boolean value){
this.courseSelected = value;
}
In CourseSelectionAdapter class, when a checkbox is click, set the value of the checkbox with the method above
holder.courseSelectedCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked){
checkBoxCounter++;
courseDisplay.setCourseSelected(isChecked);
}else {
checkBoxCounter--;
}
System.out.println("Count is: "+ checkBoxCounter);
}
});
Finally, change showResult() like this
public void showResult() {
String result = "Selected Courses are :";
for (CourseDisplay p : courseDisplay_data) {
if (p.getCourseSelected()){
result += "\n" + p.getCourseName();
}
}
Toast.makeText(this, result+"\n",Toast.LENGTH_LONG).show();
}
In my app there is a Edit text and below there is a list with check box.When user selects a particular checkbox,that value is being displayed in the edittext.Now if user writes some values in the edittext and then selects the checkbox,then the value which user had typed is overridden by the selected value.I want both the values to be displayed in the edittext

holder.tvContact.setText(data.get(i).getEmail());
to
String s = holder.tvContact.gettext().toString();
holder.setText(s + ", " + data.get(i).getEmail());
My project contains listView(homelistView) that contains button(btnList).
When I click on button(btnList) it must go to another Activity. I tried a lot but I didn't find a good example.
Please suggest me a good example regarding this.
Below is my code:
Here is my listview contains button. When on click of button it must go to other activity
--------------------------------A--
text text button(btnList) B
--------------------------------C---
text text BUTTON(btnList) D
--------------------------------E--
homempleb.xml
Before i used this code in xml. buttonlist worked fine for me as per below code
<ListView
android:id="#+id/homelistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.04"
android:dividerHeight="0dip" >
</ListView>
EfficientAdapter.java
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
this.context=context;
}
In your ViewHolder class you need to add `Button btnList.`
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent next=new Intent(context, SeviceDetails.class);
context.startActivity(next);
}
});
homempleb.xml
Currently i added scroll index to my listview and changed the code as per below.. Listbutton is not working for me now.. Plz help me u can see code for quick reference in EfficientAdapter.JAVA-----> getview method--->holder.btnList.
<com.woozzu.android.widget.IndexableListView

The problem is in onInterceptTouchEvent method. You are using IndexableListView from woozzu, and this class overrides onInterceptTouchEvent to return true. This means that IndexableListView always steal touch events from your child's views so it can provide it to IndexScroller. You can change this behavior if instead of returning true you enter this condition:
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if (mScroller != null && mScroller.contains(ev.getX(), ev.getY()))
return true;
return super.onInterceptTouchEvent(ev);
}
This way only events meant to interact with IndexScroller will be consumed. Other events will be propagated to children's views, and your button will be clickable.
In your Efficient adapter class declare ViewHolder holder outside getView method
and do as MoshErsan said.
Also Change your
convertView = mInflater.inflate(R.layout.homemplebrowview, null);
to
convertView = mInflater.inflate(R.layout.homemplebrowview, parent,false);
in your adapter, just move
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "STAT", Toast.LENGTH_SHORT).show();
Intent next = new Intent(context, Home.class);
Log.i("next23", "next");
context.startActivity(next);
}
});
just before return convertView;
you need to set the listener every time the adapter returns a view.
