The exception is occurring on the line “rowTxt.setText” and I can’t, for the life of me, figure out why.<\/p>\n
Here’s my code<\/p>\n
@Override\npublic View getView(int position, View convertView, ViewGroup parent)\n{\n View rowView = convertView;\n\n if(rowView == null)\n {\n LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);\n rowView = inflater.inflate(mResourceId, null);\n }\n\n Friend friend = mFriendsList.get(position);\n TextView rowTxt = (TextView) rowView.findViewById(R.id.rowtext);\n Log.i(\"name\", friend.getmName());\n rowTxt.setText(friend.getmName());\n\n return rowView;\n}\n<\/code><\/pre>\nLogcat output:<\/p>\n

EDIT: I figured out the issue with the help of corlettk. In short, I was assigning my listadapter like so:<\/p>\n
FriendsArrayAdapter fAdapter = new FriendsArrayAdapter(FriendsActivity.this, android.R.simple_list_item_1, mFriendsList);\n<\/code><\/pre>\nI did this because initially I had a generic listadapter that did not accommodate my Friend object; never thought to change it.<\/p>\n
So when setAdapter went into my FriendsArrayAdapter it searched the id of simple_list_item_1 for R.id.rowtext, which it did’t find. The fix was to change the above call to<\/p>\n
FriendsArrayAdapter fAdapter = new FriendsArrayAdapter(FriendsActivity.this, R.layout.row_layout, mFriendsList);\n<\/code><\/pre>\n(row_layout is the name of my XML file)<\/p>\n
\n- \n
Fly,<\/p>\n
What’s the output of that Log.i(\"name\", friend.getmName());<\/code> statement? If friend<\/em> is NOT null, then I’d guess that rowTxt<\/em> is. Debug print it to find out…<\/p>\nFurther I’d guesse that you’ve got yourself a dodgy view-ID; or maybe that view just hasn’t been added to a collection. Are you missing some initialisation code earlier on?<\/p>\n
Cheers. Keith.<\/p>\n<\/li>\n<\/ol>\n
