Update your code as below. Set choice mode to CHOICE_MODE_SINGLE when you crate listview and before set adapter. Remove CHOICE_MODE_SINGLE from button click.
listview = (ListView) findViewById(R.id.listview1);
listview.setChoiceMode(AbsListView.CHOICE_MODE_SINGLE);
listview.setAdapter(adapter);
Also, You need to setItemChecked in onItemClick of listview.
Check below example code.
public class MainActivity extends Activity {
private ListView mListView;
private String[] mData = new String[] { "xxx", "yyy", "zzz", "aaa" };
private BaseAdapter mAdapter;
private int mLastCorrectPosition = -1;
private int mButtonPosition = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mListView = (ListView) findViewById(R.id.list_view);
mListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
mAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_activated_1, mData);
mListView.setAdapter(mAdapter);
mListView.setSelector(new ColorDrawable(0));
mListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if (position == mButtonPosition) {
if (mLastCorrectPosition != -1) {
mListView.setItemChecked(mLastCorrectPosition, true);
}
else {
mListView.setItemChecked(mButtonPosition, false);
}
// here show dialog
}
else {
mLastCorrectPosition = position;
// here refresh fragment
}
}
});
}
}

As I could not find any perfect solution i tried it in a different manner alough its a bit diffenrt from what i wanted i.e on click i used my displayListView() funtion and got the work done
ischeckboxVisible = true;
Runnable run = new Runnable() {
#Override
public void run() {
displayListView();
}
};
getActivity().runOnUiThread(run);
and coming to getView i have used:
if (!ischeckboxVisible)
{
holder.name.setVisibility(View.GONE);
}
if (ischeckboxVisible)
{
holder.name.setVisibility(View.VISIBLE);
}
so every time i do the click it changes the ischeckboxVisible to either true or false and initializes the displatListview() and it works.
I have had help from here Android hide and show checkboxes in custome listview on button click
Hope this might come in handy for some one out there.
Please check below code if it helps you,
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Database_Contact contact = (Database_Contact) contactlist.get(position);
contact.setSelected(!contact.isSelected());
if(contact.isSelected())
{
((CheckBox) view.findViewById(R.id.checkbox_all)).setVisibility(View.VISIBLE);
}
else
{
((CheckBox) view.findViewById(R.id.checkbox_all)).setVisibility(View.GONE);
}
}
});

i have tried all thing to send all the data of list view to another activty please suggest me how can i do it ??
Make the list static and u can then access it in any activity. Make sure u initialise the list
milk class extends serializable firstly
then u do
make object of milk class in mainactivity class
Milk milk=new Milk(this);
Intent i=new Intent(getApplicationContext(),Update.class);
i.putExtra("emnumber",(Serializable)milk);
startActivity(i);
then u can pick the value in update class
if(getIntent().getSerializableExtra("emnumber")!=null) {
con = (ArrayList<Contact>) getIntent().getSerializableExtra("emnumber");
email_mobile = contactList.get(0).nsme;
pass__word = contactList.get(0).amount;
you can implement as:
public class Milk implements Parcelable{
......
}
Send arraylist as:
intent.putExtra("files", "your arraylist");
obtain arraylist as:
Intent inIntent = getIntent();
list=inIntent.getParcelableArrayListExtra("files");
Try this. May be it help.
Send arraylist to activity through extras.
intent.putStringArrayListExtra("ARRAY_LIST", arrayList);
Retrieve arraylist in activity.
arrayList= i.getStringArrayListExtra("ARRAY_LIST");
If u have to send arraylist other than string then.
intent.putParcelableArrayListExtra("ARRAY_LIST", (ArrayList<Milk>) milkArrayList);
Milk class must be parcellable

change your reject button and showDialog code to

showdilog(position);
holder.statustextview.setText("Rejected");
holder.relatvie1.setBackgroundResource(R.color.rejectcolor);

and showDualog to

I am a beginner to Android. Now I am working with ListView using custom adapter and custom view. Custom adapter is created as into a separate file. But inside my custom adapter, I set up a click listener for a button of the layout of the list view row. But my problem is how can I update items of the adapter inside event listener that is created inside the custom adapter.
This is my Listview Fragment:
public class TaskListFragment extends Fragment {
private DatabaseHelper dbHelper;
private TextView taskTitle;
private ListView taskListView;
private ArrayAdapter adapter;
private ArrayList<Task> items;
private int optionFocusedItemIndex;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
dbHelper = new DatabaseHelper(getActivity());
View view= inflater.inflate(R.layout.task_list, container, false);
taskTitle = (TextView)view.findViewById(R.id.task_textview);
taskListView = (ListView)view.findViewById(R.id.listViewTaskList);
int type = getArguments().getInt("type");
switch (type){
case R.integer.task_list_all:
items = dbHelper.getAllTasks();
adapter = new TaskListAdapter(getActivity(),items);
taskListView.setAdapter(adapter);
taskTitle.setText("All tasks");
break;
}
taskListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
int tagId = Integer.valueOf(view.getTag().toString());
optionFocusedItemIndex = position;
showOptionDialog(tagId);
return true;
}
});
return view;
}
public void showOptionDialog(final int id)
{
LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
View view = layoutInflater.inflate(R.layout.row_option_dialog, null);
final AlertDialog alertDialog = new AlertDialog.Builder(getActivity()).create();
Button doneBtn = (Button)view.findViewById(R.id.btn_row_option_done);
doneBtn.setOnClickListener(new View.OnClickListener() {

Inside the fragment, when I click the done button listView adapter is updated properly and it is working find. Done button is inside the AlertDialog box that appear when long click on one of the rows of list view.
The problem is here.
This is my custom adapter class:
public class TaskListAdapter extends ArrayAdapter<Task> {
private final Context context;
private final ArrayList<Task> values;
private final DatabaseHelper dbHelper;
public TaskListAdapter(Context context,ArrayList<Task> values)
{
super(context,-1,values);
this.context = context;
this.values = values;
this.dbHelper = new DatabaseHelper(context.getApplicationContext());
}
#Override
public View getView(final int position,View convertView,ViewGroup parent)
{
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.task_list_row,parent, false);
rowView.setTag(values.get(position).getId());
TextView rowDescription = (TextView)rowView.findViewById(R.id.task_row_description);
rowDescription.setText(values.get(position).getDescription());
ImageView rowStatusIcon = (ImageView)rowView.findViewById(R.id.task_row_status_icon);
Long currentDateMillSec= System.currentTimeMillis();
Long dateMillSec = CommonHelper.convertStrDateToMilSec(values.get(position).getDate());//(date==null)?0:date.getTime();
if(values.get(position).getDone()==Boolean.TRUE)
{
rowStatusIcon.setImageResource(R.drawable.done_icon);
}
else if(dateMillSec>0 && dateMillSec<currentDateMillSec)
{
rowStatusIcon.setImageResource(R.drawable.failed_icon);
}
else{
rowStatusIcon.setImageResource(R.drawable.todo_icon);
}
TextView dateTf = (TextView)rowView.findViewById(R.id.task_row_date);
dateTf.setText(values.get(position).getDate());
Button doneBtn = (Button)rowView.findViewById(R.id.task_row_done_btn);
doneBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dbHelper.markAsDone(values.get(position).getId());
//How can I update the listview items here ?
}
});
return rowView;
}
}
So how can I update the listview items and listview from the click event listener of done button that is inside custom adapter class.

I got the answer, actually it is too simple. What I need to do is just add this code inside the click listener of done button in the custom adapter.
This is the click listener of the doneBtn in custom adapter:
doneBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dbHelper.markAsDone(values.get(position).getId());
//How can I update the listview items here ?
if(values!=null)
{
Task oldTask = values.get(position);
oldTask.setDone(Boolean.TRUE);
values.set(position,oldTask);
notifyDataSetChanged();
}
}
});
I want to select all check boxes in a listview but I'm not able to get checkbox objects from the listview. I can select a single check box but not multiple check boxes.
Your suggestion are appreciable.

#Override

There is too much code to read, so I give you a sample how to do that:
int count = list.getCount();
for (int i = 0; i < count; i++) {
View child = list.getItemAtPosition(i);
//check that child..
}
or
int count = list.getChildCount();
for (int i = 0; i < count; i++) {
View child = list.getChildAt(i);
//check that child..
}
selectall.setOnClickListener(new onClickListener(){
#Override
public void onClick(View v) {
for (int i = 0; i < list.size(); i++) {
list.getItem(i).setChecked(true);
}
}
});
try doing soething like this
