Question

android spinner问题，在其他类中如何获取spinner选中的值？附代码，每次运行到这里就卡死了~求大神~

public void onClick(View v) {
// TODO Auto-generated method stub

result.setText(" ");
String busline = key.getText().toString();
Spinner spinner = null;

Bus bus = new Bus();
StringBuffer lines = new StringBuffer();
Cursor cursor = null;

if (busline != null && !busline.equals("")) {

System.out.println(spinner.getSelectedItem().toString());
if(spinner.getSelectedItem().toString().equals ("长沙"))
cursor = database.rawQuery(
"select id,line,time,station,opposite from bus_line where city='长沙' 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 '%"
+ busline + "%'", null);
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 '%"
+ busline + "%'", null);

Answer 1

speed.setOnItemSelectedListener(new OnItemSelectedListener() {

public void onItemSelected(AdapterView<?> adapter, View view,
int position, long id) {
sendBroadcast(new Intent("ACTION").putExtra("position", position));//通过广布把选中的位置发过去，如果你要发送这个位置的数据，那么你可以通过position获取。
}
在接收的类，写个广播接收器就可以了。

如果我使用intent+bundle来实现spinner选中值的传递的话，要怎么实现呢？

追答

都说了发广播了，试试不就知道行不行了？反正我是这样做的

就是刚刚试过了，值传不过来才追问的嘞，嘿嘿~~可能我代码没弄好啦~

追答

你把代码发过来我看看你是怎么写的咯
