Hi, I've encountered same problem. Solution is:
Define your resource like this: <?xml version="1.0" encoding="utf-8"?> <view class="your.owner.view" xmlns:android="http://schemas.android.com/apk/res/android"; android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <CheckBox android:focusable="false" android:clickable="false" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_marginRight="5dip" android:id="android:id/checkbox" android:layout_marginLeft="5dip"/> <TextView android:id="@+id/person_name" android:text="test" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:textSize="18dip" android:layout_marginLeft="5dip"/> </view> Define your view class public class your.owner.view extends LinearLayout implements Checkable { // Add your constructors @Override public boolean isChecked() { // TODO Auto-generated method stub return this.checked; } @Override public void setChecked(boolean checked) { // TODO Auto-generated method stub getCheckBox().setChecked(checked); this.checked = checked; refreshDrawableState(); // Append your event handler here } @Override public void toggle() { // TODO Auto-generated method stub //getCheckBox().setChecked(!checked); setChecked(!checked); } private CheckBox getCheckBox() { if (checkbox == null) { checkbox = (CheckBox) findViewById(android.R.id.checkbox); // checkbox.setFocusable(false); // checkbox.setClickable(false); // The check box should decline the click event, hence the list item could be clicked. } return checkbox; } private CheckBox checkbox; private boolean checked; } zealot On 5月28日, 下午7时58分, praneet pandit <[email protected]> wrote: > and the romain guy video you looking > forhttp://code.google.com/events/io/2009/sessions/TurboChargeUiAndroidFa... > > regards, > Ravi - The PPite > PathPartner Tech > > On May 25, 9:15 am, Paul <[email protected]> wrote: > > > > > This has to do with the fact that ListView recycles views.
