class adapter:
public class ChildrenAdapter extends ArrayAdapter<Child> {

private final ArrayList<Child> childrenArrayList;
public ChildrenAdapter(Context context, ArrayList<Child> childrenArrayList) {
super(context, R.layout.row_child, childrenArrayList);
this.context = context;
this.childrenArrayList = childrenArrayList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// 1. Create inflater
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// 2. Get rowView from inflater
View rowChildView = inflater.inflate(R.layout.row_child, parent, false);
// 3. Get the two text view from the rowView
TextView nameView = (TextView) rowChildView.findViewById(R.id.name);
TextView dateView = (TextView) rowChildView.findViewById(R.id.date);
TextView scoreView = (TextView) rowChildView.findViewById(R.id.score);
// 4. Set the text for textView
//String text = childrenArrayList.get(position).getNomEnfant())+" "+childrenArrayList.get(position).getNomEnfant();
nameView.setText(childrenArrayList.get(position).getNomEnfant()+" "+childrenArrayList.get(position).getPrenomEnfant());
dateView.setText("22/12/2012");
scoreView.setText(String.valueOf(childrenArrayList.get(position).getIdEnfant()));
scoreView.setBackgroundResource(R.drawable.circular_textview);
// 5. retrn rowView
return rowChildView;
}
}
Whene i click to the row of listview i get the "id" but how i can pass it to the popupMenu.
The solution: it just add settag(position) to imageview in getview, then :
public void showMenu(View v) {
PopupMenu popup = new PopupMenu(this, v);
popup.setOnMenuItemClickListener(this);
popup.inflate(R.menu.poupup_menu);
popup.show();
listView.performItemClick(v, (Integer) v.getTag(),listView.getItemIdAtPosition((Integer) v.getTag()));
}

You can use interface to communicate between them
In your adapter class, initialize
private OnItemSelectedListener mListener;
and add these methods
public void setOnItemClickLister(OnItemSelectedListener mListener) {
this.mListener = mListener;
}
//Creating an interface
public interface OnItemSelectedListener {
public void onItemSelected(String s);
}
in onClick function in adapter
use this
mListener.onItemSelected(id);
//id is your string
you can call it in MainActivity,
adapter.setOnItemClickLister(new OnItemSelectedListener() {
#Override
public void onItemSelected(String s) {
//you will get the string here, you can pass it as an argument in popup menu
}
});

On the adapter Side:
view.findViewById(R.id.menu_btn).setTag(id);
On the ListActivity Side:
public void showPopUp(View v){
currentId = v.getTag().toString();
PopupMenu popupMenu=new PopupMenu(this,v);
popupMenu.setOnMenuItemClickListener(ListActivity.this);
MenuInflater inflater=popupMenu.getMenuInflater();
inflater.inflate(R.menu.my_pop_up,popupMenu.getMenu());
popupMenu.show();
}
On XML side:
<ImageButton android:id="#+id/menu_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_overflow"
android:layout_marginStart="10dp"
android:layout_marginEnd="20dp"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:onClick="showPopUp"/>
Note: onClick="showPopUp" is very critical here.
This should be helpful. Thank you.

How to call every object in adapter?

I have a list of array adapters that have the following layout which contains checkbox, textview increase, textview count, and textview decrease :
layout product adapter.
what the problem is how to call or implement clicklistener from ProdukActivity.java on each object that appears on the adapter. I just want to know how does it work with object in adapter so i can count the product price in every checkbox is checked.
Here is my adapter code :
public class ProductAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;

Add listener for every object like below, inside getView of adapter. And inside the listener, do your handling
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_produk, null);
final CheckBox namaProduk = (CheckBox) convertView.findViewById(R.id.checkBox_productName);
TextView kurangProduk = (TextView) convertView.findViewById(R.id.decrease_product);
TextView hitungProduk = (TextView) convertView.findViewById(R.id.count_product);
TextView tambahProduk = (TextView) convertView.findViewById(R.id.increase_product);
TextView hargaProduk = (TextView) convertView.findViewById(R.id.product_price);
ProductModel produk = productItems.get(position);
namaProduk.setText(produk.getProduct_name());
hargaProduk.setText(produk.getProduct_price());
namaProduk.setOnCheckedChangeListener(
new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
//check here
}
}
}
);
kurangProduk.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
//do your task here

In your code listtache in initialization but it is empty list .you cannot remove item if it is empty.if you want remove item from listview than you should be use item which are use in adapter.
In below example listtache replace to mListItem.
For example:
String listviewid;
List<Item> mListItem;
HashMap<String,String> hashMap = new HashMap<>();
List<String> idlist = new ArrayList<>();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

txtmen = (TextView) rootView.findViewById(R.id.textmenu);
img = (ImageView) rootView.findViewById(R.id.imgmenu);
progressBar = (ProgressBar) rootView.findViewById(R.id.ProgressBar1);
listview = (ListView) rootView.findViewById(R.id.listtask);
type = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Montserrat-Light.otf");
txtmen.setTypeface(type);
listview.setOnItemClickListener(this);
mListItem = new ArrayList<Item>();
ht= new Httppars();
new ParseJSonDataClass(container.getContext()).execute();
return rootView;
}
private class ParseJSonDataClass extends AsyncTask<Void, Void, Void> {
public Context context;
String FinalJSonResult;
public ParseJSonDataClass(Context context) {
this.context = context;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected Void doInBackground(Void... voids) {
httpwebservice htp = new httpwebservice(Link.affichertache);
try {
htp.ExecutePostRequest();
if (htp.getResponseCode() == 200) {
FinalJSonResult = htp.getResponse();
if (FinalJSonResult != null) {
JSONArray jsonArray = null;
try {
jsonArray = new JSONArray(FinalJSonResult);
JSONObject jsonObject;
Item itm;
for (int i = 0; i < jsonArray.length(); i++) {
itm = new Item();
jsonObject = jsonArray.getJSONObject(i);
idlist.add(jsonObject.getString("idt").toString());
itm.setNomt(jsonObject.getString("nomt"));
itm.setDatet(jsonObject.getString("datet"));
itm.setHeuredebut(jsonObject.getString("heuredebut"));
itm.setTempstotal(jsonObject.getString("tempstotal"));
itm.setDescription(jsonObject.getString("description"));
mListItem.add(itm);
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Toast.makeText(context, htp.getErrorMessage(), Toast.LENGTH_SHORT).show();
}
}
} catch (Exception e) {

}
return null;

How to set listview row clickable only one time in android?

Explanation:
I have a listview in my fragment. When I click one of the row of the listview it goes to another activity.In listview,I got the data from the adapter.
Inside the adapter view,I set the setOnClick().
Problem is when I click one of the row multiple time it is opening multiple activity.I want to restrict only one time click on the particular row over the listview item.
Here is my fragment where I get the listview and set the adapter-
public class HomeFragment extends Fragment{
public HomeFragment() {

This adapter set the listrow item into listview.
In ScheduleAdapter.java i set the onclick() on the convertView in which i called a GetValue class which is only implement a Asynctask to get the data and called and intent then it goes to an activity.
Means HomeFragment->ScheduleAdapter->GetValue->Scorecard
Here,
HomeFragment is fragment which have listview
ScheduleAdpter is an adapter which set data to listview which reside in homefragment
GetValue is class which implement some important task and it passed an intent and goes to an activity(It's work as a background)
ScoreCard is my activity which called after click on the row of the listview which reside in HomeFragment.
Please, help me to solve out this problem.

You can use a flag in Listview click - isListClicked, and set flag value as false in onPostexecute method of Aysnc task class -GetValue
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!isListClicked){
match_key = arr_matchKey.get(position);
MainActivity activity = (MainActivity) context;
GetValue gv = new GetValue(context);
gv.setFullUrl(match_key);
gv.setAccessToken(activity.getMyData());
gv.execute();
isListClicked = true;
}
}
});

If you want to prevent multiple activities being opened when the user spams with touches, add into your onClick event the removal of that onClickListener so that the listener won't exist after the first press.

Easy way is you can create a model class of your json object with those field you taken in holder class. And add one more boolean field isClickable with by default with true value.Now when user press a row for the first time you can set your model class field isClickable to false. Now second time when user press a row,you will get a position of row and you can check for isClickable. it will return false this time.
Model Class :
public class CountryInfoModel {
//other fields to parse json object
private boolean isClickable; //<- add one more extra field
public boolean isClickable() {
return isClickable;
}
public void setIsClickable(boolean isClickable) {
this.isClickable = isClickable;
}
}
listview click perform :
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//country_list is your list of model class List<CountryInfo>
if(country_list.get(position).isClickable())
{
//Perform your logic
country_list.get(position).setIsClickable(false);
}else{
//Do nothing : 2nd time click
}
}
});

Try creating your custom click listener for your listview and use it. In this way
public abstract class OnListItemClickListener implements OnItemClickListener {
private static final long MIN_CLICK_INTERVAL=600;
private long mLastClickTime;
public abstract void onListItemSingleClick(View parent, View view, int position, long id);
public OnListItemClickListener() {
// TODO Auto-generated constructor stub
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
long currentClickTime=SystemClock.uptimeMillis();
long elapsedTime=currentClickTime-mLastClickTime;
mLastClickTime=currentClickTime;
if(elapsedTime<=MIN_CLICK_INTERVAL)
return;
onListItemSingleClick(parent, view, position, id);
}
}

pass data from fragment inside view pager to another activity

i hope you guys can help me. it`s drivin me crazy find the solution...
i already read some question that similar with my problems, but none solved mine.
here`s the problems
1 have 2 activity...
first --> i have activity that contain a view pager which hold 3 tab fragment.
in this first activity i extends with fragmentActivity
and here the code

Very old question, but no answer. I'm sure you have found a fix by now, but anyway.
You're changing the songs list object in background, and if Android decides to redraw your list (user scrolls your list), effectively accessing the songs list object, it may have changed and cause this exception to be thrown.
You need to use a temporary songs list and create a new adapter with it to update your list, thus not changing the current adapter list until you set a new adapter from the main UI thread.
