android - ListView short blink on OnItemClickListener

Question

In OnItemClick() method I load new Activity. My ListView item blinks on OnItemClick() (I mean, changes brightness a little or something - don't know how to say it correctly), but blinks just for a moment and then returns to its previous appearance before new Activity is loaded. I want that ListView item stayed blinked all the time before new Activity is loaded, not for just a little moment. How to do it?

Answer 1

You can use View.setOnClickListener for this..

when you are passing the intent to next page change the background color of listview item

    view.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                arg0.setBackgroundColor(Color.RED);
                Intent intent = new Intent(MainActivity.this, CheckinoutPage.class);
                startActivity(intent);
            }
        });

public class MainActivity extends Activity {

DataBaseAdapter dataBaseAdapter;
ListView listview;
MainListViewAdapter adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    dataBaseAdapter = new DataBaseAdapter(MainActivity.this);

    dataBaseAdapter.openDatabase();

    listview = (ListView) findViewById(R.id.listview1);

    adapter = new MainListViewAdapter(this, dataBaseAdapter.getAllMainDetails());
    listview.setAdapter(adapter);

}

}

Class ListView Adapter as

public class MainListViewAdapter extends BaseAdapter {

Context mContext;
LayoutInflater inflater;
private List<DetailsPOJO> details = null;
private ArrayList<DetailsPOJO> arraylist;

public MainListViewAdapter(Context context, List<DetailsPOJO> details) {
    mContext = context;
    this.details = details;
    inflater = LayoutInflater.from(mContext);
    this.arraylist = new ArrayList<DetailsPOJO>();
    this.arraylist.addAll(details);
}

public class ViewHolder {
    TextView checkindatetime, checkoutdatetime, latitudein, longitudein, addressin;

}

@Override
public int getCount() {
    return details.size();
}

@Override
public Object getItem(int position) {
    return details.get(position);
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}

@Override
public View getView(final int position, View view, ViewGroup parent) {
    final ViewHolder holder;

    if (view == null) {
        holder = new ViewHolder();
        view = inflater.inflate(R.layout.maincustomrow, null);
        // Locate the TextViews in listview_item.xml
        holder.checkindatetime = (TextView) view.findViewById(R.id.checkindatetime);
        holder.latitudein = (TextView) view.findViewById(R.id.latin);
        holder.longitudein = (TextView) view.findViewById(R.id.longin);
        holder.addressin = (TextView) view.findViewById(R.id.addin);
        holder.checkoutdatetime = (TextView) view.findViewById(R.id.checkoutdatetime);

        view.setTag(holder);
    } else {
        holder = (ViewHolder) view.getTag();
    }

    holder.checkindatetime.setText(details.get(position).getCheckindatetime());
    holder.latitudein.setText(details.get(position).getLatitudein());
    holder.longitudein.setText(details.get(position).getLongitudein());
    holder.addressin.setText(details.get(position).getAddressin());

    view.setOnClickListener(new OnClickListener() {


        @Override
        public void onClick(View arg0) {

           //This part gives color on click till the next page loads

            arg0.setBackgroundColor(Color.RED);



            String checkindate = details.get(position).getCheckindatetime();
            Intent intent = new Intent(getApplicationContext(), LatLongDeatils.class);
            intent.putExtra("checkindate", checkindate);
            startActivity(intent);
        }
    });
    return view;
}

}

Answer 3

The blink you are talking about is probably the items selector. For you what you want your best bet is probably to disable the default selector and implement it manually yourself.

So in the getView of your adapter I'd set an onClickListener to your convertView and when triggered, set the backgroundColour of it to blue or whatever colour and then perform the action. This way it will stay that colour until the next Activity is loaded. Thats the gist of the solution, if you need more help, let me know and I'll edit this answer.

Edit: In response to your 2nd comment below, try keeping track of the clicked list item using a public int in your adapter and reset it to something like -1 in the Activity/Fragments onResume. Then in the getView of your adapter check if this list item is the selected one, set the background colour, otherwise return it to white or whatever your default colour is.
