Okay, I found a workaround, using the following code: View c = listview.getChildAt(0); int scrolly = -c.getTop() + listview.getFirstVisiblePosition() * c.getHeight(); The way it works is it takes the actual offset of the first visible list item and calculates how far it is from the top of the view to determine how much we are … Read more
That behavior appears because the ListView recycles the row views as you scroll the list up and down, and because of this you get rows that were acted on by the user(the image was changed) in position were the image should be unmodified. To avoid this you’ll have to somehow hold the status of the … Read more
Use a SparseBooleanArray to get the checked items and then delete the same and refresh listview. public class MainActivity extends Activity { ListView lv; ArrayAdapter<String> adapter; Button delete; ArrayList<String> data = new ArrayList<String>(); SparseBooleanArray mCheckStates ; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.test); lv = (ListView)findViewById(R.id.listView1); lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); delete = (Button)findViewById(R.id.button1); data.add(“Windows”); data.add(“Android”); data.add(“Apple”); data.add(“Blackberry”); … Read more
This is because you are using CoordinatorLayout with ListView. You can change your implementation to RecyclerView to achieve correct scroll. or If you are tagetting above 5.0, you can use the following piece of code if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { listView.setNestedScrollingEnabled(true); } I think CoordinatorLayout only works with the children of NestedScrollingChild.
You could do the following with Otto event bus: public class UpdateListEvent { private int fragmentState; public UpdateListEvent(int fragmentState) { this.fragmentState = fragmentState; } } public class MainActivity extends ActionBarActivity { … public void updatelist() { SingletonBus.INSTANCE.getBus().post(new UpdateListEvent(fragmentState)); } } public class FragmentA extends Fragment { @Override public void onResume() { super.onResume(); SingletonBus.INSTANCE.getBus().register(this); } @Override … Read more
When extending a cursor adapter you should override the methods bindView and newView. The bindView method is used to bind all data to a given view such as setting the text on a TextView. The newView method is used to inflate a new view and return it, you don’t bind any data to the view … Read more
I got a solution. I don’t know if it is the best one. I use a custom adapter derived from ArrayAdapter for the list as described in this tutorial. In the adapter class I check if the position in the getView method is a normal row, then I inflate the row layout. If it is … Read more

The recommended solution here is to rely on built-in ListView’s selection support specifying single-choice mode for it: list.setChoiceMode(ListView.CHOICE_MODE_SINGLE); Then you should let your list item to implement to implement Checkable interface; that requires some customization of the root view of your layout. Assuming that it has LinearLayout as a root, an implementation may look like: … Read more
As explained by the programmers that did the listView in this video from GoogleIo never put a ListView inside a scroll View. If your list should not scroll use a ViewGroup like a linear Layout and add all the items to this ViewGroup in a loop in your code. If you want a whole row … Read more
