I have TextView and would like instead of filling with a Arraylist , with all items in its setText , that it be created several times on the screen, with the respective items of this array, in each setText of each TextView .

Follow the code:

public class RideRequestActivity extends AppCompatActivity implements CommunityRequestView {

    private SessionManager user;
    private String departure;
    private String arrival;



    @BindView(R.id.request_email)
    TextView email;


    @BindView(R.id.request_name)
    TextView name;


    @BindView(R.id.request_photo)
    ImageView photo;


    @BindView(R.id.textView_first)
    TextView first;

    @BindView(R.id.textView_second)
    TextView second;

    @BindView(R.id.textView_third)
    TextView third;

    @BindView(R.id.button0)
    CheckBox button0;

    @BindView(R.id.button1)
    CheckBox button1;

    @BindView(R.id.button2)
    CheckBox button2;

    @BindView(R.id.button3)
    CheckBox button3;

    @BindView(R.id.button4)
    CheckBox button4;

    @BindView(R.id.button5)
    CheckBox button5;

    @BindView(R.id.send_offer_request)
    Button send_offer_request;

    @BindView(R.id.send_ask_request)
    Button send_ask_request;

    @BindView(R.id.txtInterests)
    TextView mListView;

    @BindView(R.id.img_favorite)
    ImageView imgFavorite;

    CommunityPresenter presenter;
    UserCommunity selectedUser;
    UsersMySQLiteHelper serviceDB;
    private List<UserCommunity> userInterest = new ArrayList<UserCommunity>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            getWindow().setEnterTransition(new Fade());
        }
        setContentView(R.layout.activity_ride_request);
        serviceDB = new UsersMySQLiteHelper(AppController.getInstance().getApplicationContext());

        ButterKnife.bind(this);
        presenter = new CommunityPresenter(this);


        first.setText(presenter.getDay(0));
        second.setText(presenter.getDay(1));
        third.setText(presenter.getDay(2));

        user = new SessionManager();

        selectedUser = CommunityService.i(getContext()).selectedUser;
        reloadView();

        send_offer_request.setOnClickListener(presenter.sendRequestOnClickListener(0));
        send_ask_request.setOnClickListener(presenter.sendRequestOnClickListener(1));
        imgFavorite.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(selectedUser.favorite == 0) {
                    selectedUser.favorite = 1;
                    imgFavorite.setImageResource(R.drawable.ic_star_black_on_48px);
                }else{
                    selectedUser.favorite = 0;
                    imgFavorite.setImageResource(R.drawable.ic_star_border_black_off_48px);
                }
                selectedUser.save(serviceDB, user.getLoggedUser().getCompany());
            }
        });

        populateInterests();
        getPoints();

        imgFavorite = (ImageView)findViewById(R.id.img_favorite);
        if (selectedUser.favorite == 0){
            imgFavorite.setImageResource(R.drawable.ic_star_border_black_off_48px);
        }else{
            imgFavorite.setImageResource(R.drawable.ic_star_black_on_48px);
        }




    }

    private void getPoints() {
    }

    private void populateInterests() {
        RequestManager.UsersInterests(selectedUser.id, new FutureCallback<String>() {
            @Override
            public void onCompleted(Exception e, String result) {
                if(e== null || result != null) {

                    selectedUser.interests = user.interests;
                    String name = "";
                    TextView txt_Interests = (TextView) findViewById(R.id.txtInterests);
                    for (UserCommunity.Interest interest: selectedUser.interests
                         ) {
                           name += interest.name + " ";
                           txt_Interests.setText(name);
                    }
                    String point = "";
                    TextView points = (TextView)findViewById(R.id.txt_Points);
                    selectedUser.points = user.points;
                    point = selectedUser.points + "\npontos";
                    points.setText(point);

                }
            }
        });

    }

You can try this way by setting LinearLayout within .xml :

JAVA

LinearLayout llayout = (LinearLayout) findViewById(R.id.linearLayout);

for (int i = 0; i<selectedUser.interests.size(); i++) {
    final TextView txtItem = new TextView(this);
    txtItem.setId(i);
    point = user.points.get(i).toString() + "\npontos";
    txtItem.setText(""+point);
    llayout.addView(txtItem);
}

XML

<LinearLayout
    android:id="@+id/llayout"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"></LinearLayout>

Exactly how I solved, according to the answers in the post:

private void populateInterests() {
    RequestManager.UsersInterests(selectedUser.id, new FutureCallback<String>() {
        @Override
        public void onCompleted(Exception e, String result) {
            if (e == null || result != null) {
                UserCommunity user = new Gson().fromJson(new JsonParser().parse(result).getAsJsonObject().get("data").toString(),
                        UserCommunity.class);
                LinearLayout layout = (LinearLayout) findViewById(R.id.linear_interests);
                selectedUser.interests = user.interests;
                String name = "";
                // TextView txt_Interests = (TextView) findViewById(R.id.txtInterests);
                for (UserCommunity.Interest interest : selectedUser.interests) {
                    final TextView txt_Interests = new TextView(AppController.getAppContext());
                    txt_Interests.setBackgroundResource(R.drawable.txt_border_circle);
                    txt_Interests.setPadding(5,5,5,5);
                    name = interest.name;
                    txt_Interests.setText(name);
                    layout.addView(txt_Interests);

                }
                String point = "";
                TextView points = (TextView) findViewById(R.id.txt_Points);
                selectedUser.points = user.points;
                point = selectedUser.points + "\npontos";
                points.setText(point);

            }
        }
    });

}
