I use the following function to check the username and password from the web service. I want to use this function in different activities. But before I get a response from the server, the function reaches the end and returns false. Please suggest me a way to solve this issue with sample code.

Thank you.

public boolean checkUserPass(String username, String password) {
    userExist = false;
    UserModel user = new UserModel();
    user.setUsername(username);
    user.setPassword(password);
    Assistant.assistant.client.userCheck(user).enqueue(new Callback<Boolean>() {
        @Override
        public void onResponse(@NonNull Call<Boolean> call, @NonNull Response<Boolean> response) {
            if (response.isSuccessful()) {
                userExist = response.body();
                Log.i("MyTag", response.body().toString());
            } else {
                Log.i("MyTag", "Not Success " + response);
            }
        }

        @Override
        public void onFailure(Call call, Throwable throwable) {
            Log.e("MyTag", "Fail");
        }
    });
    return userExist;
}

I searched all the posts but didn’t get a proper answer.
