Edittext inside listview losing focus

Question

I have some TextViews and edittexts in a listview item.

What i want is to show some items, quantity,rate and total price...

Whenever quantity or rate is changed, total price also should be changed... Listitem should seen as selected when edittext is focussed.

public class MainActivity extends Activity {

private MySimpleArrayAdapterNew sampleListAdapter;
private ArrayList<HashMap<String, String>> sampleArrayList;
private ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    listView=(ListView)findViewById(R.id.listView1);
    sampleArrayList = new ArrayList<HashMap<String, String>>();
    for(int i=0;i<100;i++)
    {
    HashMap<String, String> sampleObjectMap = new HashMap<String, String>();
    sampleObjectMap.put("value1", "aaa"+i);

    sampleObjectMap.put("value2", "666");
    sampleObjectMap.put("value3", "1");
    sampleObjectMap.put("value4", "777");
    sampleObjectMap.put("value5", "444"+i);
    sampleObjectMap.put("value6", "444"+i);
    sampleArrayList.add(sampleObjectMap);
    }

    sampleListAdapter = new MySimpleArrayAdapterNew(MainActivity.this,
            R.layout.cartitem, sampleArrayList);
    listView.setAdapter(sampleListAdapter);
}

public class MySimpleArrayAdapterNew extends
        ArrayAdapter<HashMap<String, String>> {
    private Context context;
    private int layoutResourceId;
    private ArrayList<HashMap<String, String>> sampleArrayLists;

    public MySimpleArrayAdapterNew(Context context, int layoutResourceId,
            ArrayList<HashMap<String, String>> sampleArrayList) {

This changes may help.

First, change to listview:

<ListView
    android:id="@android:id/list" 
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent"
    android:descendantFocusability="beforeDescendants"
    />

Then, add this in your Manifest.xml:

<activity android:name= ".yourActivity" android:windowSoftInputMode="adjustPan"/>
