我的代码部分：
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 2) {
if (resultCode == RESULT_OK) {
startnomos = data.getStringExtra("strnom1");
startcity = data.getStringExtra("strct1");
1 Log.d("startnomos", startnomos);
2 Log.d("startcity", startcity);
}
}
else if (requestCode == 3) {
if (resultCode == RESULT_OK) {
finalnomos = data.getStringExtra("fnlnom1");
finalcity = data.getStringExtra("fnlcity1");
3 Log.d("finalnomos", finalnomos);
4 Log.d("finalcity", finalcity);
}
}
}

非常奇怪的情况是第1,2,3,4行中的Log.d给出了正确的答案，第5,6行也是正确的但是第7,8行给出了空！是不是很奇怪？与finalnomos，finalcity相比，startnomos，startcity是类似的情况。 提前谢谢
