使用这样的代码，

public class MyService extends Service {
String msg="Toast message show";
Thread t = new Thread(){
public void run(){
Message myMessage=new Message();
Bundle resBundle = new Bundle();
resBundle.putString("status", "SUCCESS");
myMessage.obj=resBundle;
handler.sendMessage(myMessage);
}
};
}
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
Toast.makeText(getApplicationContext(), "msg", Toast.LENGTH_LONG).show();
}
}
