Question

I have an xml with one textveiw and one edittext in it .I used this xml to get different rows in the list view of another xml file to list the data in that page.

The xml file that is used to list data in listview is as given below

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="2dip"
    android:paddingBottom="0dip">

    <TextView 
    android:id="@+id/tv_Sort_Address"
    android:layout_width="0dip"
    style="@style/ListTextViewStyle"
    android:layout_height="wrap_content"
    android:text="No"
     android:layout_weight="2"/>

    <EditText 
    android:textColor="#000000" 
    android:layout_height="wrap_content" 
   android:layout_width="0dip"
    android:inputType="number" 
    style="@style/EditTextStyle"
    android:background="@android:drawable/editbox_background" 
    android:id="@+id/et_Sort_Order"
     android:layout_weight="1">

    </EditText>


      </LinearLayout>

I filled the Listview with data on another xml fils as given below

simpleAdapter = new SimpleAdapter(this, alist,
                R.layout.sort_order_list_row, new String[] { "Sort_Address",
                        "Sort_FKDeliveryStatus", "Sort_PKDelivery",
                        "Sort_DeliveryOrder" }, new int[] {
                        R.id.tv_Sort_Address, R.id.tv_Sort_FKDeliveryStatus,
                        R.id.tv_Sort_PKDelivery, R.id.et_Sort_Order });
        listSortOrder.setAdapter(simpleAdapter);

The problem with me is that if i have two row in the listview and when i
placed a value in one of edit text row and move on to the another rows edit text the value placed in the first row got disappered.

 <ListView android:id="@+id/lv_Sort_Order"
       style="@style/ListTextBackGround"
     android:layout_width="match_parent"  
     android:layout_height="match_parent"
     android:layout_weight="1" 
     android:layout_marginLeft="5dip"      
     android:descendantFocusability="afterDescendants"     
     android:layout_marginRight="5dip" >
     </ListView>

to solve this I placed android:descendantFocusability="afterDescendants" in the list view page to get focus on to the merged page. But it didn’t solve the problem. Will anyone help me please.

Is there any property I need to be placed in the list view or in the merged Page?

Use this code :   

public class ListViewDemo extends Activity {

    private ListView listViewScore = null;
    private ListViewAdapter listViewAdapter = null;
    private String[] usernameArr = null;
    private String[] scoreArr = null;
    //ArrayList<String>  usernameArrLst = null ,scoreArrLst = null;
    //private Helper helper = null;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        listViewScore=(ListView)findViewById(R.id.listViewScore);

        usernameArr = new String[]{"Alan","Bob","Carl","Doaniel","Evan","Fred","Gram"};
        scoreArr = new String[usernameArr.length];

        //usernameArrLst = new ArrayList<String>(Arrays.asList(usernameArr));
        //scoreArrLst = new ArrayList<String>(Arrays.asList(scoreArr));

        listViewAdapter = new ListViewAdapter();
        listViewScore.setAdapter(listViewAdapter);
    }

    class ListViewAdapter extends BaseAdapter{

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            if(usernameArr==null){
                return 0;
            }

            return usernameArr.length;
        }

        @Override
        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return usernameArr[position];
        }

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

        @Override
        public View getView(int position, View view, ViewGroup parent) {
            // TODO Auto-generated method stub
            final ViewHolder viewHolder ;
            View rowView=view;

            if(rowView==null){
                LayoutInflater layoutinflate =LayoutInflater.from(ListViewDemo.this);
                rowView=layoutinflate.inflate(R.layout.listviewnewtext, parent, false);

                viewHolder = new ViewHolder();

                viewHolder.tv_Sort_Address = (TextView)rowView.findViewById(R.id.tv_Sort_Address);
                viewHolder.et_Sort_Order = (EditText)rowView.findViewById(R.id.et_Sort_Order);

                viewHolder.et_Sort_Order.addTextChangedListener(new TextWatcher() {

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

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

                    @Override
                    public void afterTextChanged(Editable s) {
                        // TODO Auto-generated method stub
                        scoreArr[viewHolder.ref] = s.toString();

                    }
                });

                rowView.setTag(viewHolder);
            }else{
                viewHolder = (ViewHolder) rowView.getTag();
            }

            viewHolder.ref = position;

            viewHolder.tv_Sort_Address.setText(usernameArr[position]);
            viewHolder.et_Sort_Order.setText(scoreArr[position]);

            return rowView;
        }

    }//class ends

    class ViewHolder{
        TextView tv_Sort_Address;
        EditText et_Sort_Order;
        int ref;
    }
}
