The method OnActivityResult(int, int, Intent) of type MainActivity must override

Question

OnActivityResult

Answer 1

实现这个方法需要调用父类方法   加上 super.OnActivityResult(...);
…… 英文不至于这么差吧

Answer 2

找到原因了，不过还是要谢谢给位。这里要重写的是onActivityResult()方法，而不是OnActivityResult();
大小写搞错了。 @Override
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if(requestCode==0&&resultCode==0)
{
Bundle data=intent.getExtras();
String resultCity=data.getString("city");
city.setText(resultCity);
}
}
