Question

I have a Layout which contains a textview and editText on the top, then after a listView and at the bottom i have 4 buttons.

I want my listview items to contain a imageView and 4 textViews.

I have the main layout with all the views in the 1st statement and a seperate list_item.xml (linear layout) which contains all the elements (imageview and 4 textviews) which each listview item must contain.

How can I populate the listview in my main layout with list_item.xml layout.

1. I have populated a listview using a list_item.xml which contains only TextView tag (not a linear or relative layout).

2. I also populated some other listview using a custom array adapter, but here the main layout contains only the list view item layout but not the top textview and edit view and bottom 4 buttons.

I think my problem is a combination of both point1 and point2. can anyone explain how to achieve this?

You need to implement a custom adapter like this…

  private class myAdapter extends ArrayAdapter<yourclass> {

    private ArrayList<yourclass> items;

    public myAdapter(Context context, int textViewResourceId, ArrayList<yourclass> items) {
            super(context, textViewResourceId, items);
            this.items = items;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
            View v = convertView;
            if (v == null) {
                LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                v = vi.inflate(R.layout.list_item, null);
            }
            yourclass o = items.get(position);
            if (o != null) {
                    TextView tt = (TextView) v.findViewById(R.id.txt1);
                    TextView bt = (TextView) v.findViewById(R.id.txt2);
        //similarly for 2 more textviews and a imageview
                    if (tt != null) {
                          tt.setText("Name: "+o.getitemName());                            }
                    if(bt != null){
                          bt.setText("Status: "+ o.getitemStatus());
             //similarly...and getitemName ,getitemStatus are functions of your class.. to get the values..
                    }
            }
            return v;
    }

}
