I started building an android app (btw I'm totally new to android and not that experienced with Java). I want it to do a GET-Request to a server, get back a json and then do something with that json.

The code below works fine but it's very long and I can imagine that after implementing a few buttons in this activity it's gonna be a real mess

public class secondActivity extends Activity implements OnClickListener 
@Override
public void onCreate(final Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 this.setContentView(R.layout.login_formular);
 View v = findViewById(R.id.button2);
 v.setOnClickListener(this);



@Override
public void onClick(View v) 
 if(v.getId() == R.id.button2) 
 OkHttpClient client = new OkHttpClient();
 String url="https://example.com/json";
 Request request= new Request.Builder()
 .url(url)
 .build();
 client.newCall(request).enqueue(new Callback() 
 @Override
 public void onFailure(Call call, IOException e) 
 e.printStackTrace();
 

 @Override
 public void onResponse(Call call, Response response) throws IOException 
 if(response.isSuccessful())
 final String res= response.body().string();
 final Gson gson= new Gson();
 final Employee employee=gson.fromJson(res, Employee.class);
 secondActivity.this.runOnUiThread(new Runnable() 
 @Override
 public void run() 
 TextView txt= findViewById(R.id.txt3);
 txt.setText("employee: " + employee.name);
 
 );
 
 
 );
 

My idea was to outsource the code for the http and inside the onclick event calling this function to a new class but it doesn't work.

The Request is working fine but my employee only exists inside onResponse and I have no ide how to return it.

getEmployeeName.java

public class getEmployeeName 
public static String reqName()
 OkHttpClient client = new OkHttpClient();
 String url="https://example.com/json";
 Request request= new Request.Builder()
 .url(url)
 .build();
 client.newCall(request).enqueue(new Callback() 
 @Override
 public void onFailure(Call call, IOException e) 
 e.printStackTrace();
 
 @Override
 public void onResponse(Call call, Response response) throws IOException 

 if(response.isSuccessful())
 String res= response.body().string();
 Gson gson= new Gson();
 Employee employee=gson.fromJson(res, Employee.class);
 
 
 );
 return employee;

secondActivity.java

public void onClick(View v) 
 if(v.getId() == R.id.button2) 
 String name = getEmployeeName.reqName();
 secondActivity.this.runOnUiThread(new Runnable() 
 @Override
 public void run() 
 TextView txt= findViewById(R.id.txt3);
 txt.setText("employee: " + name);
 
 );
 

What I am doing wrong?
Thanks
