protected static Context Context = null;
int i;
public String editnewmainmenu, menuname,edittext;

Bitmap bmp, resizedbitmap;
Bitmap[] bmps;
Activity activity = null;
private LayoutInflater inflater;

private ImageView[] mImages;
String[] itemimage;
TextView[] tv;
String itemname, itemcode;
public String[] itemnames, itemcodes;
HashMap<String, String> map = new HashMap<String, String>();

public EditMainMenulistview(Context context, JSONArray imageArrayJson) {
    Context = context;
    // inflater =
    // (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    // imageLoader=new ImageLoader(activity);
    inflater = LayoutInflater.from(context);
    this.mImages = new ImageView[imageArrayJson.length()];
    this.bmps = new Bitmap[imageArrayJson.length()];
    this.itemnames = new String[imageArrayJson.length()];
    this.itemcodes = new String[imageArrayJson.length()];

    try {

        for (i = 0; i < imageArrayJson.length(); i++) {
            JSONObject image = imageArrayJson.getJSONObject(i);
            qrimage = image.getString("menuimage");
            itemname = image.getString("menuname");
            itemcode = image.getString("menucode");
            itemnames[i] = itemname;
            itemcodes[i] = itemcode;

            byte[] qrimageBytes = Base64.decode(qrimage.getBytes());

            bmp = BitmapFactory.decodeByteArray(qrimageBytes, 0,
                    qrimageBytes.length);
            int width = 100;
            int height = 100;
            resizedbitmap = Bitmap.createScaledBitmap(bmp, width, height,
                    true);
            bmps[i] = bmp;

            mImages[i] = new ImageView(context);
            mImages[i].setImageBitmap(resizedbitmap);

            mImages[i].setScaleType(ImageView.ScaleType.FIT_START);

            // tv[i].setText(itemname);

Answer 1

Please use the following code

public View getView(final int position, View convertView, ViewGroup parent) {
    View vi = convertView;
    if(vi == null) {

         vi = inflater.inflate(R.layout.editmainmenulist, null);
    }

    EditText text = (EditText) vi.findViewById(R.id.editmaimenu);
    ImageView image = (ImageView) vi.findViewById(R.id.menuimage);
    TextView tv = (TextView) vi.findViewById(R.id.<textViewId>); //replace with  
                                                                  //textView ID

    image.setImageBitmap(bmps[position]);

    text.append(itemnames[position]);
     edittext = text.getText().toString();
text.addTextChangedListener(new TextWatcher() {

    public void afterTextChanged(Editable s) {
         Log.v("LOG","After text change value "+s.toString());
    }

    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        // TODO Auto-generated method stub

    }

    public void onTextChanged(CharSequence s, int start, int before,
            int count) {
        // TODO Auto-generated method stub

    }

});
     System.out.println(edittext);
        //Toast.makeText(Context, edittext, Toast.LENGTH_LONG).show();
     tv.setText(edittext);
   return vi;
}

You can get the value in afterTextChange method
