android学习
android新手求助我在做显示数据库表信息的列表时出错了
simpleadapter adapter = new simpleadapter(this, data, r.layout.item,
new string[]{"name","phone","amount"}, new int[]{r.id.name,r.id.phone,r.id.amount});
log.i(tag, data.get(9).tostring());
listview.setadapter(adapter);
到最后一行 listview.setadapter(adapter);时报错，空指针
目前不知原因何在，求解答
