How to get custom dialog activity while clicking on a button in listview in android?

here is my code for ArrayAdapter. When i click on LinearLayout "cat" it gives error on dialog.show(). I don't know how to create custom dialog within ArrayAdapter class.
Everything work fine when i remove creating dialog part.
Thanks in advance
CategoryAdapter.java
public class CategoryAdapter extends ArrayAdapter<String> {
private final Context context;
String[] menu = new String[25] ;
String[] menu2 = new String[25];
String[] menu3 = new String[25];
private LayoutInflater inflater;
viewholder vh;
public CategoryAdapter(Context context, String [] menu,String [] menu2,String [] menu3) {
super(context, R.layout.categoryadapter, menu);
this.context = context;
this.menu = menu;
this.menu2=menu2;
this.menu3=menu3;
}
public View getView(final int position, View convertView, ViewGroup parent) {
{
vh=new viewholder();
if (inflater == null)
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.categoryadapter, parent, false);
vh.cat=(LinearLayout) convertView.findViewById(R.id.category);
convertView.setTag(vh);
}
vh.cat.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(getContext());
dialog.setContentView(R.layout.update_categore_dialog);
dialog.setTitle("Update Your Category");
dialog.show();
Toast.makeText(getContext(), "Clicked", Toast.LENGTH_LONG).show();
}
});
return convertView;
}
public class viewholder
{
LinearLayout cat;
}
}

Use context instead getContext()
final Dialog dialog = new Dialog(context);
Finally, Just pass context
vh.cat.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.update_categore_dialog);
dialog.setTitle("Update Your Category");
dialog.show();
Toast.makeText(getContext(), "Clicked", Toast.LENGTH_LONG).show();
}
});

Try-
Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.update_categore_dialog);
dialog.setTitle("Update Your Category");
dialog.show();

try this below link, hope you like it.
OrderDetailListAdatper adapter = new OrderDetailListAdatper(Yourclass.this,Resource,
listorderlistInfo);
//set your adapter..
in your adapter getview, paste that code and it works fine for me.
holder.btnDelete.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
AlertDialog.Builder alert = new AlertDialog.Builder((Activity)_context);
alert.setMessage("Do you want to delete?");
alert.setNegativeButton("CANCEL",
new DialogInterface.OnClickListener() {
#Override
public void onClick(
DialogInterface dialog,
int whichButton) {
dialog.cancel();
}
});
alert.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
#Override
public void onClick(
DialogInterface dialog,
int whichButton) {
OrderDetailListAdatper.this._listOrderListInfoAdapter
.remove(position); OrderDetailListAdatper.thisnotifyDataSetChanged();
}
});
alert.create().show(); // btw show() creates and shows it..
}
});

In your getView() method, Replace getContext() with your context variable.
vh.cat.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(context);
//remaining code...
}
});
And in your initialization of CateogoryAdapter don't pass getApplicationContext(), instead pass in the context (Activity.this) like this.
CategoryAdapter adapter = CategoryAdapter(YourActivity.this, menu, menu2, menu3)

Unable to refresh the ListView with customAdapter

I have been working and messing with my code from last two days.
I have a List View in a Fragment and a Button .
On clicking a button i add the data to List View entered through Dialog
What I am unable to do is refresh the ListView after clicking Ok Button.
Here is my Code
However it loads when i exit the app and resume again
Any Help will be appreciated
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
int title = getArguments().getInt("title");
final EditText input = new EditText(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
return new AlertDialog.Builder(getActivity())
.setView(input)
.setIcon(R.drawable.ic_launcher)
.setTitle(title)
.setPositiveButton(R.string.alert_dialog_ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
String Value = input.getText().toString();
String normalizednumber = NormalizePhoneUtilities
.normalizePhoneNumber(Value);
ContactModel contactModel = new ContactModel(
"Hitesh", normalizednumber, String
.valueOf(3));
ContactsDatabaseWorker sm = new ContactsDatabaseWorker(
getActivity());
sm.AddSmartContact(contactModel);
databaseWorker = new ContactsDatabaseWorker(
getActivity());
// LinkedList<Cursor> list = new
// LinkedList<Cursor>();
// list=databaseWorker.getAllData();
run = new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
customAdapter = new CustomCursorAdapter(
getActivity(), databaseWorker
.getAllData());
customAdapter.notifyDataSetChanged();
listview.invalidateViews();
listview.refreshDrawableState();
listview.setAdapter(customAdapter);
}
};
getActivity().runOnUiThread(run);
isModal = false;
}
})
.setNegativeButton(R.string.alert_dialog_cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
}
}).create();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (isModal) // AVOID REQUEST FEATURE CRASH
{
View view = inflater.inflate(R.layout.smartalert_fragment,
container, false);
listview = (ListView) view.findViewById(R.id.lvSmartAlert);
return super.onCreateView(inflater, container, savedInstanceState);
}
View view = inflater.inflate(R.layout.smartalert_fragment, container,
false);
Button bAdd = (Button) view.findViewById(R.id.bAddContact);
bAdd.setOnClickListener(this);
listview = (ListView) view.findViewById(R.id.lvSmartAlert);
new Handler().post(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
customAdapter = new CustomCursorAdapter(getActivity(),
databaseWorker.getAllData());
listview.setAdapter(customAdapter);
}
});
return view;
}

Call notifyDataSetChanged (); in adapter.

Your CursorAdapter has a swapCursor() method, which you can use each time you get an updated cursor.

OnItemClickListener and OnItemLongClickListener didn't function at all. Anyone help me out here.. I did diagnose the problem but it still doesn't have function

OnItemClickListener itemListener = new OnItemClickListener() {
OnItemLongClickListener itemLongListener = new OnItemLongClickListener() {
You just define those variables but you don't assign them to your ListView.
You should call these lines somewhere:
lvMain.setOnItemClickListener(itemListener);
lvMain.setOnItemLongClickListener(itemLongListener);
UPDATE:
You also miss to register the list for context menu.
registerForContextMenu(lvMain);

implement View.OnItemClickListener and AdapterView.OnItemLongClickListener and their corresponding methods in your class.
initialize your views correctly (findViewById...)
set click listeners to your views (button.setOnClickListener(this) / button.setOnLongClickListener(this)
react to the push events in the implemented methods like:
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button:
this.doSomething();
}
}
and
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
//react to the view or react to the position
switch (view.getId()) {
case R.id.button:
this.doSomething();
}
return true;
}

You need to register listeners. Add following lines to the end of your onCreate() method.
lvMain.setOnItemClickListener(itemListener);
lvMain.setOnItemLongClickListener(itemLongListener);

I had the exact same problem. When onclick or onlongclick are enabled in the Layout; onitemclickListener wont work. Just remove the tags android:clickable and android:longclickable from your Layout XML resource and it will all work.

how to set a custom list view into a dialog box

I am developing a application which fetches some data from a web service and displays in a list view. I have implemented a custom adapter which is extended by BaseAdapter. In the getView() method I inflate the raw also.. Those are working perfectly.
My problem is I have implemented code to show a dialog box when user click on an list item, but now I want to show another dialog box which has a custom list inside it (when Yes button clicked). I also want to show some data in that listview. [I have a ArrayList filled with the data that I wanted] . I'm writing the code inside my adapter class. Can anyone give me some idea how to do it ?
This is my code:
public class NewsRowAdapter extends BaseAdapter {
private Context mContext;
private Activity activity;
private static LayoutInflater inflater=null;
private ArrayList<HashMap<String, String>> data;
int resource;
//String response;
//Context context;
//Initialize adapter
public NewsRowAdapter(Context ctx,Activity act, int resource,ArrayList<HashMap<String, String>> d) {
super();
this.resource=resource;
this.data = d;
this.activity = act;
this.mContext = ctx;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void dialogshow(final String Date,final String Start,final String End){
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(activity);
alertDialogBuilder.setTitle("Confirm your Action!");
// set dialog message
alertDialogBuilder
.setMessage("Click yes to exit!")
.setCancelable(false)
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, close
// current activity
//MainActivity.this.finish();
// Toast.makeText(mContext, "Yes clicked", Toast.LENGTH_LONG).show();
//check similer records
// ShortList sh = new ShortList();
// ArrayList<HashMap<String, String>> duplicateList;
// duplicateList=sh.getDuplicated(Date, Start, End);
//if duplicates > 1 then show the popup list
// if(duplicateList.size()>1){
AlertDialog.Builder alertDialogBuilder2 = new AlertDialog.Builder(activity);
LayoutInflater infl = activity.getLayoutInflater();
//View vi = infl.inflate(id, root)
alertDialogBuilder2.setView(infl.inflate(R.layout.dialog_row, null))
.setPositiveButton("Accept", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "Accepted", Toast.LENGTH_LONG).show();
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
alertDialogBuilder2.show();
// }
}
})
.setNegativeButton("No",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
alertDialogBuilder.show();
}
#Override
public View getView(final int position, View convertView, final ViewGroup parent) {
View vi = convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.row,null);
final TextView firstname = (TextView) vi.findViewById(R.id.fname);
final TextView lastname = (TextView) vi.findViewById(R.id.lname);
final TextView startTime = (TextView) vi.findViewById(R.id.stime);
final TextView endTime = (TextView) vi.findViewById(R.id.etime);
final TextView date = (TextView) vi.findViewById(R.id.blank);
final ImageView img = (ImageView) vi.findViewById(R.id.list_image);
HashMap<String, String> song = new HashMap<String, String>();
song =data.get(position);
firstname.setText(song.get(MainActivity.TAG_PROP_FNAME));
lastname.setText(song.get(MainActivity.TAG_PROP_LNAME));
startTime.setText(song.get(MainActivity.TAG_STIME));
endTime.setText(song.get(MainActivity.TAG_ETIME));
date.setText(song.get(MainActivity.TAG_DATE));
//imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL), img);
Button accept = (Button) vi.findViewById(R.id.button1);
accept.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
final int x = (int) getItemId(position);
/*Intent zoom=new Intent(mContext, Profile.class);
zoom.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
zoom.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(zoom);*/
// get the intent from the hashmap check if there is similar date and time.
//then store them in a list or array.
String getDate = (String) date.getText();
String getStartTime = startTime.getText().toString();
String getEndTime = endTime.getText().toString();
dialogshow(getDate,getStartTime,getEndTime);
}
});
vi.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String getFname = firstname.getText().toString();
Toast.makeText(parent.getContext(), "view clicked: "+getFname , Toast.LENGTH_SHORT).show();
//get the id of the view
//check the id of the request
//call the web service acording to the id
Intent zoom=new Intent(parent.getContext(), Profile.class);
parent.getContext().startActivity(zoom);
}
});
return vi;
}

You are on the right track, Here is what i used to dynamically display a Dialog with a list of items in it.
For reference a similar Question was asked here : Android custom list dialog
//String[] list_data; Preloaded with a String array
final CharSequence[] items = new CharSequence[list_data.length];
for (int i = 0; i < list_data.length; i++) {
items[i] = list_data[i];
}
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select the data you want");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//Get the id of the item
diag_callback();
}
});
AlertDialog alert = builder.create();
alert.show();
}
public void diag_callback() {
//Do someting when the user has made his selection
}
Hope this sorts out your problem.

For your concern I hope that you know creating customized list view.
Fallow undermentioned code that contains customized dialog with customized list view. I hope you can perform Adapter and model part by your's
final Dialog new_dialog = new Dialog(getParent());
new_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
new_dialog.setContentView(R.layout.customize_dialog_list_view);
new_dialog.setCancelable(false);

String services = sp.getString("services","");
Log.i("Servicesss",bAllServices);
TextView service = (TextView) new_dialog.findViewById(R.id.cdlv_service_provider);
TextView hour = (TextView) new_dialog.findViewById(R.id.cdlv_working_hours);
TextView appointment_time = (TextView) new_dialog.findViewById(R.id.cdlv_appoint_time);
TextView appointment_date = (TextView) new_dialog.findViewById(R.id.cdlv_appoint_date);
String[] ampm = myTiming[which].split(":");
Log.d("xxxooo", ampm[0]);
appointment_time.setText(Html.fromHtml("<b>Appointment time :</b>" + myTimingToShow[which].split("/")[0]));
appointment_date.setText(Html.fromHtml("<b>Appointment date :</b>" + selected));
service.setText(Html.fromHtml("<b>Service provider :</b>"+ cuc.toTheUpperCase(bsp_name)));
hour.setText(Html.fromHtml("<b>Working hours :</b>"+ cuc.toTheUpperCase(bsp_availability)));
lv = (ListView) new_dialog.findViewById(R.id.cdlv_list);
CustomDialogArrayAdapter cdaa = new CustomDialogArrayAdapter(getApplicationContext(),m_ArrayList);
lv.setAdapter(cdaa);
new_dialog.show();
ImageButton btn_cdlv_cancel = (ImageButton) new_dialog.findViewById(R.id.cdlv_cancel);
btn_cdlv_cancel.setOnClickListener(new View.OnClickListener() {

Take your Dialog inside your activity, where you have to do code for listiview click, inside click show your dialog,
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
//show dialog.
}
});
I can see, your dialog having two buttons and one editbox, and whatever values is to be input in editbox, you updating your list value with editbox value.
Grab editbox value and update your list array, which you are setting on adapter to fill your listview.
updateQuantityButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// here you have to fetch editbox value and update your arraylist and then notify your adapter.
}
});

I believe this is because onCreateDialog() and onPrepareDialog() should be overriden in an activity, not in the adapter.
Since you declared activity to be of type Activity, calling activity.showDialog() won't have any effect.
What you have to do, is to move those methods in the activity you want the dialogs to be displayed, then pass to the CardAdapter and instance of your activity and use it in the adapter.
new CardAdapter(MyActivity.this);
//...
public class CardAdapter .... {
public MyActivity activity;
//.......
activity.showDialog
}
Though, I would suggest to use DialogFragment instead.

you can use this way when click on item of the list view then open the dialog box and whatever changes or update in list then use setNotifyDataChanged() before set the adapter on list view
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
yourActivty.this.showDialog(DIALOG_QUANTITY);
}
});
