How to highlight ListView-Items

@Override        public void onItemClick(AdapterView<?> parent, View view, int position, long arg3)        {            for(int a = 0; a < parent.getChildCount(); a++)            {                parent.getChildAt(a).setBackgroundColor(Color.BLACK);            }            view.setBackgroundColor(Color.RED);        }

You should use a Selector.

This question and its answer might help....

In your Activity:

listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {        @Override        public void onItemClick(AdapterView<?> parent, View view, int position, long itemid) {            itemOnclickList(position, view);        }    });    public void itemOnclickList(int position, View view) {          if (listview.isItemChecked(position)) {                                  view.setBackgroundDrawable(getResources().getDrawable(R.drawable.image_checked));                } else {        view.setBackgroundDrawable(getResources().getDrawable(R.drawable.image_uncheck));               }    adapter.notifyDataSetChanged();}

In your Adapter:

  public View getView(int position, View view, ViewGroup parent) {    View convertView = inflater.inflate(R.layout.listdocument_item, null);              ListView lvDocument = (ListView) parent;        if (lvDocument.isItemChecked(position)) {            convertView.setBackgroundDrawable(activity.getResources().getDrawable(R.drawable.image_checked));                       } else {            convertView.setBackgroundDrawable(activity.getResources().getDrawable(R.drawable.image_uncheck));                       }    return convertView;}

Good luck!
