private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
if (msg.what == 01234) {
Bundle bundle = msg.getData();
String MalformedURLException = bundle.getString("e1");
System.out.println(MalformedURLException);
Toast.makeText(MainActivity.mactivity, MalformedURLException, Toast.LENGTH_SHORT).show();
}
在handler里面的String 参数 怎么传出来呀
