I'm creating a ScrollView, nesting in a RelativeLayout (which contains tables). Everything is properly added to the layout. The problem is: vertically scrolling works fine, but horizontal scrolling does NOT work at all. I already tested various combinations of MATCH_PARENT, WRAP_CONTENT and FILL_PARENT. No try even worked close. So my question is: What am I missing here?

Here is the code:

public class PlayerView extends View {



    private RelativeLayout relativeLayout;

    private TableLayout tableLayout;

    private int player_loop;

    private int player_count;



    public PlayerView(Context context, int player_count){

        super(context);

        setPlayer_count(player_count);

    }



    public ScrollView create_scrollView(){



        ScrollView scrollView = new ScrollView(getContext());

        ScrollView.LayoutParams scroll_params = new ScrollView.LayoutParams(

                ScrollView.LayoutParams.MATCH_PARENT,

                ScrollView.LayoutParams.MATCH_PARENT

        );

        scrollView.setLayoutParams(scroll_params);

        scrollView.addView(create_relativeLayout());



        return scrollView;

    }



    public RelativeLayout create_relativeLayout(){



        relativeLayout = new RelativeLayout(getContext());

        RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(

                RelativeLayout.LayoutParams.MATCH_PARENT,

                RelativeLayout.LayoutParams.MATCH_PARENT

        );

        relativeLayout.setLayoutParams(relativeParams);

        create_Player_Table_Layout();



        return relativeLayout;

    }



    public void create_Player_Table_Layout(){



        for(player_loop = 1; player_loop <= player_count; player_loop++){



            relativeLayout.addView(player_table(getResources().getString(R.string.dummy_player_name) + player_loop, player_loop));



        }

    }



    public TableLayout player_table(String playername, int playernumber){



        tableLayout = new TableLayout(getContext());

        tableLayout.setId(playernumber * 1000);



        if (playernumber > 1) {



            //TABLE PLACEMENT

            RelativeLayout.LayoutParams tbl_params_New = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

            tbl_params_New.addRule(RelativeLayout.RIGHT_OF, (playernumber - 1) * 1000);

            tableLayout.setLayoutParams(tbl_params_New);

        }



        //Add Playername

        TableRow row_playername = new TableRow(getContext());

        TextView view_name = new TextView(getContext());



        TableRow.LayoutParams view_name_params = new TableRow.LayoutParams();

        view_name_params.setMargins(20,20,20,20);



        view_name.setLayoutParams(view_name_params);

        view_name.setGravity(Gravity.CENTER);

        view_name.setText(playername);

        view_name.setTextSize(20);

        view_name.setId(playernumber * 100);



        row_playername.addView(view_name);

        tableLayout.addView(row_playername);



        //Add Lifepoints

        TableRow row_lifepoints = new TableRow(getContext());

        TextView view_lifepoints = new TextView(getContext());



        TableRow.LayoutParams view_lifepoints_params = new TableRow.LayoutParams();

        view_lifepoints_params.setMargins(20, 0, 20, 20);



        view_lifepoints.setText("40");

        view_lifepoints.setTextSize(40);

        view_lifepoints.setGravity(Gravity.CENTER);

        view_lifepoints.setId(playernumber * 100 + 10);

        view_lifepoints.setLayoutParams(view_lifepoints_params);

        row_lifepoints.addView(view_lifepoints);

        tableLayout.addView(row_lifepoints);



        Log.d("Test", "Player count:" + player_count);

        for(int opponent_loop = 1; opponent_loop <= player_count; opponent_loop++){

            tableLayout.addView(commander_damage_from_player(player_loop, opponent_loop));

        }



        return tableLayout;

    }



    private TableRow commander_damage_from_player(int player_loop, int opponent_loop){



        TableRow row = new TableRow(getContext());



        TextView textView = new TextView(getContext());



        TableRow.LayoutParams layoutParams = new TableRow.LayoutParams();

        layoutParams.setMargins(20, 0, 40, 20);

        textView.setLayoutParams(layoutParams);



        textView.setText("0 | " + getResources().getString(R.string.dummy_player_name)+ " " + opponent_loop);

        textView.setTextSize(20);

        textView.setId(player_loop + 100 + opponent_loop);

        row.addView(textView);



        return row;

    }



    private void setPlayer_count(int player_count){

        this.player_count = player_count;

    }



}

And for documentation the calling class:

public class Home extends AppCompatActivity {



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);



        PlayerView playerView = new PlayerView(this, 8);

        setContentView(playerView.create_scrollView());



    }

}

The only way you can do this is by creating a horizontalscrollview to be the child of the scrollview. If you make the minor modification to your create_relativeLayout() to create a horizontalscroll view then it will work correctly. I have seen this happen in other examples.

public  HorizontalScrollView create_relativeLayout(){



    HorizontalScrollView horizontalScrollView = new HorizontalScrollView(getContext());



    relativeLayout = new RelativeLayout(getContext());

    RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(

            RelativeLayout.LayoutParams.MATCH_PARENT,

            RelativeLayout.LayoutParams.MATCH_PARENT

    );

    relativeLayout.setLayoutParams(relativeParams);

    create_Player_Table_Layout();

    horizontalScrollView.addView(relativeLayout);

    return horizontalScrollView;

}
