txtDescription.setText("");

But not worked. Any one know why it is not worked ? The Adapter class is attached

Please Help Me, Thanks in Advance!!

private class ListAdapters extends ArrayAdapter<ApplicationBean> {
    private ArrayList<ApplicationBean> items;
    private int position;

    public ListAdapters(Context context, int textViewResourceId,
            ArrayList<ApplicationBean> mTitleList) {
        super(context, textViewResourceId, mTitleList);
        this.items = mTitleList;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        this.position = position;
        if (v == null) {
            LayoutInflater inflater = (LayoutInflater) mContext
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = inflater.inflate(R.layout.applicationlistitem, null);
        }

        final ApplicationBean o = (ApplicationBean) items.get(position);

        if (o != null) {

            txtDescription = (EditText) v
                    .findViewById(R.id.description_text);



            submitButton = (Button) v.findViewById(R.id.submit_btn);
            submitButton.setTag(position);
            submitButton.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {

                        PostRequest p = new PostRequest(Integer.parseInt(v
                                .getTag().toString()));
                        p.execute();
                }

            });
        }
        return v;
    }

    @Override
    public int getItemViewType(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public int getViewTypeCount() {
        // TODO Auto-generated method stub
        return items.size();
    }

                .setMessage(result)
                .setPositiveButton("Ok",
                        new DialogInterface.OnClickListener() {
                            @Override

                                    int whichButton) {
                                dlgprogress.dismiss();
                                dlgprogress.cancel();
                                txtDescription.setText("");

You can also set any object as TAG to your button view.

So do it like this in your getView() method and I supppose it will work.

             //EDIT
         txtDescription.setTag(position); // set position to edittext

         submitButton = (Button) v.findViewById(R.id.submit_btn);
         submitButton.setTag(txtDescription); // set the current edittext object 

         submitButton.setOnClickListener(new OnClickListener() {        
                @Override
                public void onClick(View v) {
                       EditText tv = (EditText)v.getTag(); // get edittext object
                       tv.setText("");
                             //Edit
                       PostRequest p = new PostRequest(Integer.parseInt(tv
                                .getTag().toString())); // get position from edittext
                    }
                });

EDIT TO SEND Complete View

I have not tested this, but I suppose it will work if don’t work then also send the Checkbox to constructor as you send editext.

class PostTask extends AsyncTask<Void,Void,Void>
{
    CheckBox cb;
    EditText et;
    int pos;
    PostTask(int pos,View view)
    {
        cb = view.findViewById(R.id.cbox1);
        et = view.findViewById(R.id.et1);
        pos = Integer.parseInt(et.getTag().toString());
    }
}

//Now in getView change

submitButton.setOnClickListener(new OnClickListener() {     
            @Override
            public void onClick(View v) {
                   PostRequest p = new PostRequest((View)v.getParent()); // get position from edittext
            }
 });
