Android - ListView - performItemClick

Question

I\'m facing some difficults when I try to use the performItemClick funcion of the ListView.

All I want to do is to perform a click programatically i

Answer 1

myListView.getChildAt(0) returns null because used this very soon.

use a delay for it.

or use below code:

private class MyAdapter extends BaseAdapter
{
private final Context context;
private HashMap views;

public MyAdapter(Context context)
{
    this.context = context;
    views = new HashMap<>();
}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    if(convertView == null)
    {
        if(views.get(position) == null)
        {
            final LayoutInflater layoutInflater = LayoutInflater.from(context);
            convertView = layoutInflater.inflate(R.layout.my_grid, null, false);

            views.put(position, convertView);
        }
        else
            convertView = views.get(position);
    }

    TextView tv = convertView.findViewById(R.id.langView);
    tv.setText(languageList.get(position));

    return convertView;
}
}

and

adapter = new MyAdapter(getActivity());
myListView.setAdapter(adapter);

Runnable r = new Runnable()
{
    @Override
    public void run()
    {
        myListView.performItemClick(adapter.getView(position, null, myListView), position, 0);
    }
};

myListView.postDelayed(r, 100);
