My problem is to populate the gridview. I already saw through the debugger that my code is reading the data correctly from the table, but when the activity is started, the gridview do not display nothing. My getView() method is: public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub TextView label = (TextView)convertView; if (convertView == null) { convertView = new TextView(this.context); label = (TextView) convertView; } label.setText((getDataFromTable().get(position)).toString()); //the geDataFromTable() returns a list with the data from the table (tested observing the debugger) return(convertView); } In my activity I have: ... ColetaDatabaseAdapter adapter = new ColetaDatabaseAdapter(this, R.layout.data_display); GridView g = (GridView) findViewById(R.id.grid); g.setAdapter(adapter); ... But I can not see the gridview on the display...
