I have a SimpleAdapter that I use in a listview to show data that comes from the database. Follow the code below

Map<String, String> map;
for(int i = 0;i < buscaCombustivel.getCount();i++) {
    map = new HashMap<String, String>();
    map.put("idItem", buscaCombustivel.getString(buscaCombustivel.getColumnIndex("id")));
    map.put("text1", buscaCombustivel.getString(buscaCombustivel.getColumnIndex("dataEntrada")));
    map.put("desc","Litros: " + buscaCombustivel.getString(buscaCombustivel.getColumnIndex("litrosEntrada")) + " | Valor unitário: " +
            buscaCombustivel.getString(buscaCombustivel.getColumnIndex("valorUnitarioEntrada")) + " | Valor total: " +
            buscaCombustivel.getString(buscaCombustivel.getColumnIndex("valorTotalEntrada")) + "\n");
    list.add(map);
    buscaCombustivel.moveToNext();
}
SimpleAdapter adapterDropDown = new SimpleAdapter(getApplicationContext(), list, R.layout.custom_list, new String[] { "text1", desc", "idItem" }, new int[] { R.id.text1, R.id.desc, R.id.idItem });
listDados.setAdapter(adapterDropDown);

R.id.text1, used in SimpleAdapter, has a property called DrawableLeft in its xml. I needed to change this property depending on a certain value that comes from the database. Is it possible to do that?

You can use the getView method on your SimpleAdapter and the setCompoundDrawablesWithIntrinsicBounds setting in the first argument the specific drawable , which in your case would be R.drawable.tic14 . This will ensure that the drawable will be inserted to the left of your TextView . Here's an example:

SimpleAdapter adapterDropDown = new SimpleAdapter(getApplicationContext(), list,
    R.layout.custom_list, new String[] {
        "text1",
        desc,
        idItem
    }, new int[] {
        R.id.text1, R.id.desc, R.id.idItem
    }) {

    public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        TextView text1 = (TextView) view.findViewById(android.R.id.text1);

        int imgResource = R.drawable.tic14;
        text1.setCompoundDrawablesWithIntrinsicBounds(imgResource, 0, 0, 0);

        return view;
    };
};
