public void onClick(View v) {

Cursor cursor = null;
if (busline != null && !busline.equals("")) {
System.out.println(spinner.getSelectedItem().toString());
if(spinner.getSelectedItem().toString().equals ("北京"))
cursor = database.rawQuery(
"select id,line,time,station,opposite from bus_line where city='北京' and line like '%"
+ busline + "%'", null);
if(spinner.getSelectedItem().toString().equals("深圳"))
cursor = database.rawQuery(
"select id,line,time,station,opposite from bus_line where city='深圳' and line like '%"

if(spinner.getSelectedItem().toString().equals("广州"))
cursor = database.rawQuery(
"select id,line,time,station,opposite from bus_line where city='广州' and line like '%"

哪位大神帮我看看，哪里错了啊？每次运行这里就强退，spinner的值获取错了吗？

强退应该能具体看到是哪一行啊

学会使用logcat 是android 开发的第一步 目测是数据库语言写的有问题， 找个sqlite测试一下语言
