Apps Chronometer in ListView Row ?

[zeldan]

Hi, I got a row xml for my ListView with chronometer

<LinearLayout android:layout_width="fill_parent"
android:id="@+id/layout_orders_list_row_ll_Timer" 
android:focusable="false"   
android:layout_height="wrap_content" 
android:gravity="center_horizontal|right"
android:layout_gravity="center">
<Chronometer android:text="@+id/Chronometer01"
    android:layout_height="wrap_content" android:layout_width="wrap_content"
    android:id="@+id/layout_orders_list_row_chr_Timer"
    android:focusable="false" android:focusableInTouchMode="false"
    android:layout_gravity="center" android:enabled="true">
</Chronometer>
<Button android:background="@drawable/check" android:layout_height="wrap_content" 
    android:id="@+id/layout_orders_list_row_bt_Done" 
    android:layout_width="wrap_content" android:focusable="false"                   android:onClick="OnRowButtonClick">
</Button>

and I want to start my chronometer for each row.I'm getting data from database and fill the adapter.After that I'm connecting to each chronometer and trying to calculate it.But it doesn't work.

listView.setAdapter(simpleAdapter);
 
       for (int i = 0; i < simpleAdapter.getCount(); i++) {
 
        LinearLayout vwParentRow = (LinearLayout) simpleAdapter.getView(i,
                null, null);
 
        LinearLayout ChildTop = (LinearLayout) vwParentRow.getChildAt(0);
        LinearLayout ChildTop2 = (LinearLayout) ChildTop.getChildAt(1);
        final Chronometer chrono = (Chronometer) ChildTop2.getChildAt(0);
        chrono.setText("00:00:00");
        chrono.setBase(SystemClock.elapsedRealtime());
        chrono.start();
 
        chrono.setOnChronometerTickListener(new OnChronometerTickListener() {
 
            public void onChronometerTick(Chronometer arg0) {
                // TODO Auto-generated method stub
 
                    long minutes = ((elapsedTime - chrono.getBase()) / 1000) / 60;
                    long seconds = ((elapsedTime - chrono.getBase()) / 1000) % 60;
                    currentTime = minutes + ":" + seconds;
                    arg0.setText(currentTime);
                    elapsedTime = elapsedTime + 1000;
 
            }
 
        });
 
    }
 
    listView.invalidate();

What I'm doing wrong? Maybe there is other solution how to start chronometer in each row?

I've done this stuff, with making a holder view.I made short tutorial how to use it
Jazz with Android: "View holder" in ListView

in example listview with checkboxes
