POAndroid: Custom Cursor Adapter Trouble
text
Body
copied!<p>I am wondering if someone may be able to point me in the right direction or lend a pair of eyes and see where I am going wrong with my custom cursor adapter class for a listview.</p> <p>Basically, I had it "working", in the sense that it would populate the listview with the firstname from the database, and not move to the next row.Now however, it will throw up an error and not enter into list, so any help is appreciated.</p> <p>Basically what I am having trouble in achieving is reading a name and image path from database and apply it to a row.xml with my custom adapter.Here is my code:</p> <pre><code>public class CustomAdapter extends SimpleCursorAdapter { private LayoutInflater mInflater; private Context context; private int layout; //private Cursor c; String animal_name; String img_path; public CustomAdapter(Context context,int layout, Cursor c, String[] from, int[] to){ super(context, layout, c, from, to); //this.c = c; this.context = context; this.layout = layout; } @Override public View getView(int position, View convertView, ViewGroup parent){ View row = convertView; ViewWrapper wrapper = null; Cursor c = getCursor(); animal_name = c.getString((c.getColumnIndexOrThrow(MyDBManager.KEY_ANIMALNAME))); img_path = c.getString((c.getColumnIndexOrThrow(MyDBManager.KEY_IMGPATH))); if(row == null){ LayoutInflater inflater = LayoutInflater.from(context); row = inflater.inflate(R.layout.row, null); // row is passed in as "base" variable in ViewWrapper class. wrapper = new ViewWrapper(row); row.setTag(row); } else{ wrapper=(ViewWrapper)row.getTag(); } wrapper.getLabel().setText(animal_name); wrapper.getIcon().setImageResource(R.id.icon); return (row); } </code></pre> <p>}</p> <pre><code>class ViewWrapper{ View base; TextView label = null; ImageView icon = null; ViewWrapper(View base){ this.base = base; } TextView getLabel(){ if(label== null){ label=(TextView)base.findViewById(R.id.author); } return (label); } ImageView getIcon(){ if(icon == null){ icon=(ImageView)base.findViewById(R.id.icon); } return (icon); } </code></pre> <p>}</p> <p>and have been setting the adapter as follows</p> <pre><code>CustomAdapter mAdapter = new CustomAdapter(this, R.layout.row, myCursor, new String[]{"animal_name"}, new int[]{R.id.animal}); this.setListAdapter(mAdapter); </code></pre> <p>Any help is greatly appreciated.</p>
