setOnItemClickListener not working in Fragment

I am trying to change the text and check box response of the clicked list item but I am not able to do so. As I not able to get the clicked list item.
The fragment is a part of view pager.
Here is my code,
public class ParticipantsFragment extends Fragment {
private ParticipantAdapter mAdapter;
SwipeRefreshLayout refreshLayout;
private String mParticipantId, mEventId, mGender;
ParticipantsAsyncTask task;
public ParticipantsFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mEventId = getArguments().getString(Config.BUNDLE_KEY_EVENT_ID);
mParticipantId = getArguments().getString(Config.BUNDLE_KEY_PARTICIPANT_ID);
mGender = getArguments().getString(Config.BUNDLE_KEY_GENDER);
Log.v("fragh", mEventId + " " + mParticipantId);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.participant_list, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.no_participant);
task = new ParticipantsAsyncTask();
task.execute();
ListView participantListView = (ListView) rootView.findViewById(R.id.participant_list);
refreshLayout = (SwipeRefreshLayout) rootView.findViewById(R.id.swipe_refresh_layout_participant_list);
participantListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.v("Clicked Participant",mAdapter.getItem(position).getParticipantName());
EditText notes = (EditText) rootView.findViewById(R.id.participant_list_item_notes);
String text = notes.getText().toString();
Log.v("Participant Text",text);
CheckBox checkBox = (CheckBox) rootView.findViewById(R.id.participant_list_item_checkbox);
String check;
if(checkBox.isChecked())
{
check = "1";
}
else
{
check = "0";
}
}
});

submit.setOnClickListener(new View.OnClickListener() {

}
});

participantListView.setAdapter(mAdapter);
participantListView.setEmptyView(textView);
refreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override

task = new ParticipantsAsyncTask();
task.execute();
refreshLayout.setRefreshing(false);
}
});
return rootView;

progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);

}
#Override

// Clear the adapter of previous participant data
mAdapter.clear();
// If there is a valid list of {#link Event}s, then add them to the adapter's
// data set. This will trigger the ListView to update.
if (data != null && !data.isEmpty()) {
mAdapter.addAll(data);
}
}
#Override

List<Participant> result;
if (!mGender.isEmpty()) {
HashMap<String, String> map = new HashMap<String, String>();
map.put(Config.KEY_EVENT_ID, mEventId);
map.put(Config.KEY_PARTICIPANT_ID, mParticipantId);
map.put(Config.KEY_GENDER, mGender);
result = QueryUtils.extractParticipantData(map, Config.FEVER_GENDER_FILTER_PARTICIPANT_URL);
} else {

map.put(Config.KEY_EVENT_ID, mEventId);
map.put(Config.KEY_PARTICIPANT_ID, mParticipantId);
Log.v("law", mEventId + ", " + mParticipantId);
result = QueryUtils.extractParticipantData(map, Config.FEVER_ALL_PARTICIPANT_URL);

Found the answer atlast.
Don't use setOnItemClickListener for item click. Use item view click inside adapter method by using setOnClickListener(). Do things in onClick()
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View listItemView = convertView;
if (listItemView == null)
{
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.participant_list_item, parent, false);
}
listItemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
Toast.makeText(mContext, "click item",Toast.LENGTH_LONG).show();
}
});
Participant currentParticipant = getItem(position);
if(currentParticipant.getParticipantGender().equals("F"))
{
TextView idView = (TextView) listItemView.findViewById(R.id.participant_list_item_id);
idView.setTextColor(getColor(mContext, R.color.colorPrimary));
idView.setText(currentParticipant.getParticipantId());
}
else if(currentParticipant.getParticipantGender().equals("M"))
{
TextView idView = (TextView) listItemView.findViewById(R.id.participant_list_item_id);
idView.setTextColor(getColor(mContext, R.color.colorAccent));
idView.setText(currentParticipant.getParticipantId());
}
TextView nameView = (TextView) listItemView.findViewById(R.id.participant_list_item_name);
nameView.setText(currentParticipant.getParticipantName());
final EditText notesView = (EditText) listItemView.findViewById(R.id.participant_list_item_notes);
notesView.setText(currentParticipant.getParticipantNotes());
CheckBox checkedView = (CheckBox) listItemView.findViewById(R.id.participant_list_item_checkbox);
if (currentParticipant.getParticipantCheck().equals("1"))
{
checkedView.setChecked(true);
}
else
{
checkedView.setChecked(false);
}
return listItemView;
}
Remove this from participant_list_item.xml
android:descendantFocusability="blocksDescendants"
Thank you every one for the help.

<CheckBox
android:id="#+id/participant_list_item_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:focusable="false"
android:clickable="false"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp" />
Try to replace your CheckBox and add this two line
android:focusable="false"
android:clickable="false"

Try this should work in participant_list_item.xml and remove from listview
android:descendantFocusability="blocksDescendants"

you have to do it like this
private EditText notes;
private CheckBox checkBox;
and put these above onclick
notes = (EditText) rootView.findViewById(R.id.participant_list_item_notes);
String text = notes.getText().toString();
Log.v("Participant Text",text);
checkBox = (CheckBox) rootView.findViewById(R.id.participant_list_item_checkbox);
edittext and check box are the view in the listview
hope this will help you

android:clickable=true
Make sure that you have added clickable property to true.
In participantslist.xml file:
<ListView
android:id="#+id/participant_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#color/divider"
android:dividerHeight="1dp"
android:descendantFocusability="beforeDescendants"
android:drawSelectorOnTop="true"
android:headerDividersEnabled="true"
android:clickable=true/>
And let me know if this suggestion was wrong?

setOnItemClickListener() not working on ListView (select always first row)

I have created a custom ListView by extending LinearLayout for every row (Contact) and i need to select the item, but the method "setOnItemClickListener()" not working. I have just put a onItemSelectedListener under and now the method "setOnItemClickListener" select always the first item though i select other row
MainActivity:
public class MainActivity extends AppCompatActivity {
private ListView lvPhone;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

Replace your PhoneBook_row.xml with the one I am putting up here, I have tried this and it worked for me. I have changed all your android:clickable="true" to android:clickable="false". The reason for doing this is, all of your child views consume click and the result is your parent view i.e ListView not getting the click event. Hope this helps.

Looks like you are missing the override.
Add an #Override before the function as shown below.
lvPhone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
Also adding android:clickable = true in the layout file wouldn't be necessary.

You have changed your question , anyway i believe you can now get the item selected listener working. To get the item which is selected you can use the position as below
lvPhone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
PhoneBook phoneBook = listPhoneBook.get(position);
Toast.makeText(MainActivity.this, phoneBook.getName() , Toast.LENGTH_SHORT).show();
//where getName is a function to get the name in the phonebook class
}
});

How can I change the icon of a button in android gridView row?

I want to change the button of android grid view row item, when I click in the first row, I can change the button (play) to (pause), then when I go to another row, also I can change the play to pause, but I need to change the previous row automatically to pause, because it is now still play.
I have tried the code below but not effect.

StopPlayer and change previous icon
public void stopPlayer(Context c, int current, int previous) {
System.out.println("current : " + current);
System.out.println("previous : " + previous);
if (mp != null && mp.isPlaying()) {
mp.stop();
}
if (current!=previous){
View v= this.getView(previousPosition, null, null);
Button b = (Button) v.findViewById(R.id.buttonPlay);
b.setBackground(c.getResources().getDrawable(R.drawable.ic_action_play));
this.notifyDataSetChanged();
mGridview.refreshDrawableState();
}
}
see the attached image please;

Instead of doing this
View v= this.getView(previousPosition, null, null);
change your drawable on item click method
mGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Button b = (Button) view.findViewById(R.id.buttonPlay);
b.setBackground(c.getResources().getDrawable(R.drawable.ic_action_play));
your_adapter.notifyDataSetChanged();
}
});
I think , this will work for you :)

I think of you question as a partial refresh one. We all run into partial refresh problem when dealing with ListView or GridView. As for your case, partial refresh may be like this:
private void refreshPartially(int position){
int firstVisiblePosition = listview.getFirstVisiblePosition();
int lastVisiblePosition = listview.getLastVisiblePosition();
if(position>=firstVisiblePosition && position<=lastVisiblePosition){
View view = listview.getChildAt(position - firstVisiblePosition);
if(view.getTag() instanceof ViewHolder){
ViewHolder vh = (ViewHolder)view.getTag();
//holder.play.setBackgroundResource(resId);//Do something here.
...
}
}
}

ListView + ImageButton + descendantFocusability

This is my 'main' code.. i want detect the press here
ListView lv = (ListView)findViewById(R.id.listView);
Item_ListAdapter adapter = new Item_ListAdapter(ListActivity.this, items);
lv.setAdapter(adapter);
lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parnet, android.view.View view, int position, long id) {
// Que item ha sido pulsado
Toast.makeText(getApplicationContext(), String.valueOf(position), Toast.LENGTH_SHORT).show();
Log.d("aaa", String.valueOf(position) );
}
});

I believe in order to have BOTH the listView row and the ImageButton clickable, you'll need to set both of these on the ImageButton object:
android:focusable="false"
android:focusableInTouchMode="false"
Give that a shot. I'd also try using an onClickListener on your ImageButton instead of the touchListener.

Shortcuts for removing and editing in a listview in android

I have a listview that is a list of events. For each event, I want to have shortcut icons right next to its title for editing and removing. If I tab one of those, it should bring me to another Intent for editing/removing events. How do I achieve this?
My xml has a listview like this:
<ListView
android:id="#+id/listView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
</ListView>
and for each text view:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/rowTextView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp" >
</TextView>
Thank you!

What you need to do is to create a custom Adapter and override the getView method like so:
private class MySecondAdapter extends ArrayAdapter<MiniTask>
{
private ArrayList<MiniTask> list;
public MySecondAdapter(Context context, int textViewResourceId, ArrayList<MiniTask> miniTaskList)
{
super(context, textViewResourceId, miniTaskList);
this.list = new ArrayList<MiniTask>();
this.list.addAll(miniTaskList);
}
public View getView(final int position, View convertView, ViewGroup parent)
{
miniTask = miniTaskList.get(position);
ViewHolder holder = new ViewHolder();
{
LayoutInflater inflator = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflator.inflate(R.layout.check_list_item_new, null);
holder.title = (TextView) convertView.findViewById(R.id.tvItemTitle);
holder.commentsPicturesButton = (ImageView) convertView.findViewById(R.id.iAddCommetOrPicture);
holder.commentsPicturesButton.setTag(position);
holder.commentsPicturesButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
Intent intent = new Intent(getApplicationContext(), PicturesAndCommentsActivity.class);
intent.putExtra(TasksListActivity.KEY_ID, task.getId());
intent.putExtra("mini_task_text", miniTask.getTitle());
startActivity(intent);
}
});
holder.selected = (CheckBox) convertView.findViewById(R.id.cbCheckListItem);
holder.selected.setTag(position);
holder.selected.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
{
Log.d(TAG, "pressed the checkbox: " + v.getId() + " in position: " + position + " tag: " +v.getTag() +" and item from array: " + miniTaskList.get(position) );
CheckBox checkbox = (CheckBox) v;
miniTaskList.get(position).setSelected(checkbox.isChecked());
numOfCheckedMiniTasks = 0;
for(int i=0;i<miniTaskList.size();i++)
{
miniTask = miniTaskList.get(i);
if(miniTask.isSelected())
{
numOfCheckedMiniTasks ++;
}
}
int percent = (int)(numOfCheckedMiniTasks * 100.0f) / miniTaskList.size();
Log.d(TAG, "the percentage is: " +percent);
tasksRepository.get(tasksRepository.indexOf(task)).setMiniTasksPercentageComplete(percent);
}
}
});
}
holder.title.setText(miniTask.getTitle());
holder.selected.setChecked(miniTask.isSelected());
return convertView;
}
}
In this case I have a checkbox for every row as well, you can ignore it, and the holder is:
static class ViewHolder
{
TextView title;
CheckBox selected;
ImageView commentsPicturesButton;
}
While the XML layout for every row is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/try2"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<CheckBox
android:id="#+id/cbCheckListItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginBottom="10dp"
android:background="#drawable/checkbox_checklist_selector"
android:button="#drawable/checkbox_checklist_selector" />
<TextView
android:id="#+id/tvItemTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="5dp"
android:paddingRight="10dp"
android:paddingTop="13dp"
android:text="#string/checklist_item_string"
android:textColor="#color/my_darker_gray" />
</LinearLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:paddingTop="6.5dp" >
<ImageView
android:id="#+id/iAddCommetOrPicture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:contentDescription="#drawable/comment_or_photo_icon"
android:src="#drawable/comment_or_photo_icon" />
</RelativeLayout>
UPDATE:
holder.iParameterWidget.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
currentParameterPosition = position;
}
}

for this you have to create your custom row separately. There are plenty of example you can find. You can see following links to start
