    1. you need to create viewitem.xml like your requirements.
      means you just put margin in that .xml file and get space between two listdata.

  4. This is a plagiary!! You are a FRAUD and plagiarist because you copy it completely textually from https://github.com/dinocore1 and didn't give any credit. At least you should be creative and change the methods name.

    1. Maybe so. I saw the GitHub version first but because I couldn't load it into my Android Studio, I found this simple listing easier to handle. It's good either way. Thanks sandip.

    1. you need to create constructor of HorizontalListView class.

      because in your error code tell me that.
      12-18 05:45:44.007: E/AndroidRuntime(1324): Caused by: java.lang.InstantiationException: can't instantiate class com.example.hlv.HorizontalListView; no empty constructor

      so, please create one empty constructor first.

    1. Because Scroll View is a one Control and It also contain the scroll property like this one. so, no need to use Scroll View as parent of this view.

  32. Hello sandip. Thanks for this. It may well have had it origins elsewhere but your listing is the one that got me productively started on a problem I have had for some while. That was for a double row horizontal list view to place in the vertical centre of a protract screen on a Android. I managed to add the second row with little or no trouble and have added item locaters that place the desired item (eg the selected item) in the centre of the screen. Adjusting the size of my list presented to the horizontal list view proved to be trickier. In the end, I had to create a completely new Horizontal List View and make a few kludges in the onLayout(...) of the ViewGroup that holds the Horizontal List View. But, did I miss an easier way to resize my list and synchronize the Horizontal List View?

    ReplyDelete
  33. Oh no no no no. My last didn't work. I just ran out memory. So my question is how do I reset my HorizontalListView to a supplied array of different length and varied data in. The array is just and ArrayList with different selections from the same basic source. This is built into BaseAsapter mAdapater via its overrides getView and getCount. When I change the array contents, I issue a HorizontalListView instance.refresh(mApapter) call. I added refresh to the HorizontalListView class as
    public synchronized void refresh(BaseAdapter baseAdapter) {
    mScroller.forceFinished(true);
    mDataChanged = true;
    baseAdapter.notifyDataSetInvalidated();
    }
    This successfully makes the HorizontalListView display the new array correctly BUT the scroller and fling don't work. It appears its control variables are totally out of sync!! How do I remedy this.
