how to get radibutton Postion from listview On Button click in android

This is my screenshot:
This is my adapter class:
public class ListofAddressesAdapter extends ArrayAdapter<ListofAddressesDataModel> {
private Context context;
private int layoutResourceId;
HashMap<Integer, Integer> hashMap;
private List<ListofAddressesDataModel> data;
int selectedPosition = 0;
String name, phone, address;
String customeraddressid;
public ListofAddressesAdapter(Context context, int layoutResourceId,
List<ListofAddressesDataModel> data) {
super(context, R.layout.listofaddresses, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
hashMap = new HashMap<Integer, Integer>();
}
#Override
public View getView(final int position, final View convertView, ViewGroup parent) {
View row = convertView;
final ViewHolder holder;
if (row == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.name = (TextView) row.findViewById(R.id.tvsubservices);
holder.description = (TextView) row.findViewById(R.id.tvdesc);
holder.fulladd = (TextView) row.findViewById(R.id.tvfulladdr);
holder.r = (RadioButton) row.findViewById(R.id.radioButton);
holder.delet = (ImageView) row.findViewById(R.id.ivdelete);
row.setTag(holder);
} else {
holder = (ViewHolder) row.getTag();
}
final ListofAddressesDataModel item = data.get(position);
holder.name.setText(item.getName());
holder.description.setText(item.getPhone());
holder.fulladd.setText(item.getFulladdress());
holder.r.setChecked(position == selectedPosition);
holder.r.setTag(position);
holder.r.setOnClickListener(new View.OnClickListener() {
#Override

customeraddressid = data.get(selectedPosition).getCustaddid();
notifyDataSetChanged();
}
});
return row;
}
static class ViewHolder {
TextView name;
TextView description;
TextView fulladd;
RadioButton r;
ImageView delet;
}
public Object getItemAtPosition(int position) {
// TODO Auto-generated method stub
return null;
}
}
This is my activity class:

lstDataModel.add(datamodel);
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
#Override

ListofAddressesAdapter adapter = new ListofAddressesAdapter(testclass.this, R.layout.listofaddresses, lstDataModel);
add.setAdapter(adapter);
adapter.notifyDataSetChanged();
super.onPostExecute(result);
}

I want to get selected radio button position or value and id so that on button click I tried with but it always take first position. Can any one suggest me where am I doing wrong? I have to get selected radio button position so that I can get value from list of Objects. I have to send into next activity.

In adapter create a method which returns the object of selected position. Like :
public ListofAddressesDataModel getSelectedItem() {
return data.get(selectedPosition);
}
In activity, on click of the button call this method. Like :
#Override
public void onClick(View v) {
if(v.getId() == R.id.button) {
//Here you will get the selected item of which the radio button is checked
ListofAddressesDataModel selectedItem = ((ListofAddressesAdapter) add.getAdapter()).getSelectedItem();
}
}
EDIT :
Instead of below lines in getView() in adapter
holder.r.setTag(position);
holder.r.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectedPosition = (Integer) view.getTag();
name = data.get(selectedPosition).getName();
phone = data.get(selectedPosition).getPhone();
address = data.get(selectedPosition).getFulladdress();
customeraddressid = data.get(selectedPosition).getCustaddid();
notifyDataSetChanged();
}
});
just replace it with below line
holder.r.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectedPosition = position;
}
});

Thanks in Advance if some one implement Searching Via Police No (In code policy no)

I have used this as my code for search filter . i hope this helps .
yourEditText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
String Police No=yourEditText.getText().toString();
ArrayList<YouDataModel> Filter=new ArrayList<YouDataModel>();
for (DataModel data: leaveDatas) {
if (data.getUserName().toLowerCase().contains(nameToSearch.toLowerCase()) || data.getUserName().toLowerCase().equalsIgnoreCase(nameToSearch.toLowerCase()) )
{
filteredLeaves.add(data);
}
}
leaves_adapter = new Leaves_Adapter(filteredLeaves, Activity.this);
listView.setAdapter(leaves_adapter);
}
#Override
public void afterTextChanged(Editable s) {
}
});

I think I've provided sufficient information to understand the problem. GeneralHelper is a web service class to get JSON data from server.
Here I want to get order details by the user. But I am facing some problems as following...
List Items are not clickable, and when I put event handling code, it is not working
How to handle onClick event of ImageButton(imgPlus and (imgMinus) which is placed in ListView item. I tried with the code written in comment in SwipeTabFragment.java, But it is also not working.
Last problem is, Tabs are switching very well when we swipe left or right, but if we click on tabs, then not able to switch.
Please help me to solve above problems or any one of them. Thank You!

Just avoid the ImageLoader class. I expect that you can show a image from an URL. If you can do that then just use your method to show a image from an URL to the im ImageView...
Just create a new project with this files and you will understand this..

You have intentionally commented ListView's onItemclicklistener inside your onCreateView
Uncomment the code
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_items, container, false);
list = (ListView) rootView.findViewById(R.id.lstItems);
initializeFoodItems(category_id);
list.setAdapter(new ItemListAdapter(context, item_name, price_per_unit));
//ListView event handling
list.setOnItemClickListener(itemClickListener );
return rootView;
}
ImageVIew Click
Write this method anywhere
// Item Click Listener for the listview
OnItemClickListener itemClickListener = new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View container, int position, long id) {
// Getting the Container Layout of the ListView
RelativeLayout linearLayoutParent = (RelativeLayout ) container;
// Getting the inner Linear Layout
RelativeLayout linearLayoutChild = (RelativeLayout ) linearLayoutParent.getChildAt(1);
// Getting the Country TextView
ImageView iv = (ImageView) linearLayoutChild.getChildAt(0);
Toast.makeText(getBaseContext(), "Image CLicked", Toast.LENGTH_SHORT).show();
}
};

I got solution of two problems. That are...
How to handle onClick event of ImageButton(imgPlus and imgMinus) which is placed in ListView item. I tried with the code written in comment in SwipeTabFragment.java, But it is also not working.
Solution :
I am handling onclick event in ItemListAdapter.java that is working fine. Below is the code of this file. That may be helpful for others.

((TextView) row.findViewById(R.id.txtPrice)).setText(price[position] + " Rs. Each");

#Override
public void onClick(View v) {
TextView qty = (TextView) row.findViewById(R.id.txtQty);
qty.setText(String.valueOf((Integer.parseInt(qty.getText().toString()))+1));
if (Integer.parseInt(qty.getText().toString()) > 0) {
//Calculating Total Amount
int t = item_price * Integer.parseInt(qty.getText().toString());
((TextView) row.findViewById(R.id.txtTotal)).setText("Rs. " + String.valueOf(t));
}
}
});
//Decreasing Quantity
row.findViewById(R.id.imgMinus).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextView qty = (TextView) row.findViewById(R.id.txtQty);
if (Integer.parseInt(qty.getText().toString()) > 0) {

//Calculating Total Amount
int t = item_price * Integer.parseInt(qty.getText().toString());
((TextView) row.findViewById(R.id.txtTotal)).setText("Rs. " + String.valueOf(t));
}
}
});
return row;
}
}
Tabs are switching very well when we swipe left or right, but if we click on tabs, then not able to switch.
Solution : I simply put the following line in the onTabSelected() and make the tabs working. This was suggested by #AvishekDas. Again Thanks for this.
#Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction ft) {
viewPager.setCurrentItem(tab.getPosition());
}
But I'm still finding problem 1. My listView is not clickable. If any of you have solution then please post. Thank you!

May this solve your problem :
if (convertView == null)
{
LayoutInflater vi = (LayoutInflater)mContext.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.adapter_list, parent,false);
mCountryName = (TextView) convertView.findViewById(R.id.textOne);
}
mCountryName.setText(mCountry.get(position));//Write this after condition

One problem is that you're setting the text only when convertView is null. You should make sure that the line mCountryName.setText(mCountry.get(position)); is executed every single time, otherwise some items will not show up.

Atlast I solved it.............
The Problem is in my xml layout. That i have mentioned a weight for framelayout in TabHost

currentFilePath = new String[currentFiles.length];
int count = 0;
for (File f : currentFiles) {

Use custom adapter for your gridView. In the getView method you can inflate any layout you want for the cell

This the example of how i made a custom listview with Imageview and TextView. I did this because i also wanted to delete multiple items selected in the listview.
