Problems with Dialog, ListView and setOnItemClickListener

Question

I use a ListView with a custom adapter. Inside this adapter I want to use a HorizontalScrollView for displaying the full information in a row. I got long text so I have to scroll. Unfortunately my setOnItemClickListener does not recognize a click on it. It works if I delete the horizontalScrollView. I read a lot about this topic here the last few hours but nothing helps me out of this. So is it possible to receive events even if my ListView is scrollable in horizontal way too?

    public void show_alert() {

    final Dialog dia = new Dialog(this);

    dia.setContentView(R.layout.alert);

    dia.setTitle(String.format(res.getString(R.string.msg_11)));
    dia.setCancelable(true);

    list_alert = (ListView) dia.findViewById(R.id.alert_list);

    list_alert.setAdapter(new MainActivityArrayAdapter(this, GetProtokollFileNames()));                                            

    this.list_alert.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> arg0, View arg1, int pos,
                long arg3) {

            Toast.makeText(MainActivity.this,
                    "Item in position " + pos + " clicked", Toast.LENGTH_LONG).show();              
            dia.dismiss();
        }
    });               
    dia.show();
}

The class MainActivityArrayAdapter(...) uses the rowlayout.xml.

public class MainActivityArrayAdapter extends ArrayAdapter<String> {
  private final Context context;

  private String[] Values;

  public MainActivityArrayAdapter(Context context, String[] values) {
    super(context, R.layout.rowlayout, values);
    this.context = context;    
    Values = values;
  }

  @Override
  public View getView(int position, View convertView, ViewGroup parent) {

      LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

      View rowView = inflater.inflate(R.layout.rowlayout, parent, false);


    return rowView;
  }
}

but if you have a long text then display it as s singleline or you can set your horizontal scrollview's width match_parent.. — Piyush, Aug 27 '13 at 13:57
could you plz post the xml in which your are using horizontalScrollView. — Ritesh Gune, Aug 27 '13 at 14:03
I use a Dialog for showing it. This Dialog is not very wide on the Galaxy S3. — afkiwers, Aug 27 '13 at 14:04

You can implement custom views (horizontalScrollView) and override some methods:

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    boolean is_event = super.onInterceptTouchEvent(ev);
    if (is_event)
        getParent().requestDisallowInterceptTouchEvent(true);
    return ret;
}

@Override
public boolean onTouchEvent(MotionEvent ev) {
    boolean is_event = super.onTouchEvent(ev);
    if (is_event)
        getParent().requestDisallowInterceptTouchEvent(true);
    return ret;
}

This code is the solution for your problem, you just have to write list_alert.setOnItemClickListener(...) ane also setClickable(true) for listView

Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.dialog);
dialog.setTitle("Your Title");
dialog.setCancelable(true);
dialog.show();

list_alert = (ListView) dialog.findViewById(R.id.alert_list);
list_alert.setClickable(true);

list_alert.setAdapter(new MainActivityArrayAdapter(this, GetProtokollFileNames()));                                            

list_alert.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> arg0, View arg1, int pos,
            long arg3) {

        Toast.makeText(MainActivity.this,
                "Item in position " + pos + " clicked", Toast.LENGTH_LONG).show();              
        dialog.dismiss();
    }
});

What do you mean with "setOnClick(true) for listView"? The problem is that I got a horizontal bar in it. without it works great. – afkiwers Aug 28 '13 at 06:58
There is no error. Nothing is happend. It seems that the listener not watching it correctly. – afkiwers Aug 28 '13 at 07:25
hey dear it just display the toast... it will do nothing because u won't perform any action in listener – Dhrumil Aug 28 '13 at 07:29
my toast does not appear. did you test it in your app? are you able to scroll left and right? – afkiwers Aug 28 '13 at 07:32
ya i try this in my app that's why i mgive u thus solution – Dhrumil Aug 28 '13 at 13:12
How I said before. If I throw out the horizontal scrollview it works too. I don't understand what are the differences between this both options. – afkiwers Aug 29 '13 at 06:40
