Android存储多个数据

Question

I am currently using Android Network Service Discovery. With the function below, each time it runs, it returns one host name. However, I want to store all data somewhere to pass to the next activity, how will I be able to that?

public void onServiceFound(NsdServiceInfo service) {

            Log.d(TAG, "Service discovery success" + service.getServiceName());
            if (!service.getServiceType().equals(SERVICE_TYPE)) {
                Log.d(TAG, "Unknown Service Type: " + service.getServiceType());
            } else if (service.getServiceName().equals(mServiceName)) {
                Log.d(TAG, "Same machine: " + mServiceName);
            } else if (service.getServiceName().contains(mServiceName)){
                mNsdManager.resolveService(service, mResolveListener);
            }
        }

Example I have 3 names to store, how would I be able to do that?

Answer 1

Every time you get a name just add it into a list, eg myListOfNames.

just before spawning a new activity, add that list into your intent as an extra.

you can do something like this

Intent i = new Intent()
i.putExtra("my_names", TextUtils.join(",", myListOfNames));
startActivity(i);

where TextUtils.join will collapse your list into a single comma separated string.
