Мой RelativeLayout не показывает последний addView ()

/ 26 ноября 2018

Я пытаюсь добавить ребенка RelativeLayout к родителю RelativeLayout программным способом на Fragment * onCreateView().Однако после запуска моего приложения оно не имеет добавленного дочернего макета через RelativeLayout.addView().

Я создал функцию для возврата программно созданного RelativeLayout.

Вот соответствующий длинный код функции, поскольку возвращаемая иерархия RelativeLayout довольно велика: 

private RelativeLayout createCards() {
        RelativeLayout relativeLayout = new RelativeLayout(getContext());
        RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams((int) (250 * scale + 0.5f), (int) (400 * scale + 0.5f));

        layoutParams.setMargins(0, 0, (int) (15 * scale + 0.5f), 0);
        relativeLayout.setLayoutParams(layoutParams);
        relativeLayout.setBackgroundResource(R.drawable.thought_diary_list_blue);
        relativeLayout.setClickable(true);
        relativeLayout.setFocusable(true);
        relativeLayout.setPadding((int) (8 * scale + 0.5f), (int) (90 * scale + 0.5f), (int) (8 * scale + 0.5f), (int) (80 * scale + 0.5f));
        relativeLayout.setId(View.generateViewId());

        RelativeLayout firstRow = new RelativeLayout(getContext());
        RelativeLayout.LayoutParams firstRowLayoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams
                .WRAP_CONTENT);

        firstRowLayoutParams.setMargins((int) (10 * scale + 0.5f), 0, (int) (10 * scale + 0.5f), 0);
        firstRow.setPadding(0, (int) (20 * scale + 0.5f), 0, 0);
        firstRow.setLayoutParams(firstRowLayoutParams);
        firstRow.setId(View.generateViewId());

        LinearLayout linearLayout = new LinearLayout(getContext());
        LinearLayout.LayoutParams linearLayoutParams = new LinearLayout.LayoutParams((int) (40 * scale + 0.5f), LinearLayout.LayoutParams.WRAP_CONTENT);
        linearLayout.setOrientation(LinearLayout.VERTICAL);
        linearLayout.setLayoutParams(linearLayoutParams);

        TextView dateTextView = new TextView(getContext());
        LinearLayout.LayoutParams dateTextViewLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        dateTextView.setTypeface(Typeface.create("avenir", Typeface.BOLD));
        dateTextView.setText("16");
        dateTextView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
        dateTextView.setTextColor(Color.parseColor("#fff000"));
        dateTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 22);
        dateTextView.setLayoutParams(dateTextViewLayoutParams);

        TextView monthTextView = new TextView(getContext());
        LinearLayout.LayoutParams monthTextViewLayoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        monthTextView.setTypeface(Typeface.create("avenir", Typeface.NORMAL));
        monthTextView.setText("NOV");
        monthTextView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
        monthTextView.setTextColor(Color.parseColor("#fff000"));
        monthTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 22);
        monthTextView.setLayoutParams(monthTextViewLayoutParams);

        TextView yearTextView = new TextView(getContext());
        LinearLayout.LayoutParams yearTextViewLayoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        yearTextView.setTypeface(Typeface.create("avenir", Typeface.NORMAL));
        yearTextView.setText("1998");
        yearTextView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
        yearTextView.setTextColor(Color.parseColor("#fff000"));
        yearTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 22);
        yearTextView.setLayoutParams(yearTextViewLayoutParams);

        linearLayout.addView(dateTextView);
        linearLayout.addView(monthTextView);
        linearLayout.addView(yearTextView);

        ImageView imageView = new ImageView(getContext());
        RelativeLayout.LayoutParams imageViewLayoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        imageViewLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_END);
        imageView.setLayoutParams(imageViewLayoutParams);
        imageView.setBackgroundResource(R.drawable.icon_vertical_threedots);

        firstRow.addView(linearLayout);
        firstRow.addView(imageView);

        relativeLayout.addView(firstRow);

        RelativeLayout secondRow = new RelativeLayout(getContext());
        RelativeLayout.LayoutParams secondRowLayoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        secondRowLayoutParams.addRule(RelativeLayout.BELOW, firstRow.getId());
        secondRowLayoutParams.setMargins(0, (int) (20 * scale + 0.5f), 0, 0);
        secondRow.setId(View.generateViewId());
        secondRow.setLayoutParams(secondRowLayoutParams);

        ImageView secondRowImageView = new ImageView(getContext());
        RelativeLayout.LayoutParams secondRowImageViewLayoutParams = new RelativeLayout.LayoutParams((int) (250 * scale + 0.5f), (int) (150 * scale + 0.5f));
        secondRowImageViewLayoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);
        secondRowImageView.setBackgroundResource(R.drawable.td1);
        secondRowImageView.setLayoutParams(secondRowLayoutParams);

        secondRow.addView(secondRowImageView);
        relativeLayout.addView(secondRow);

        RelativeLayout thirdRow = new RelativeLayout(getContext());
        RelativeLayout.LayoutParams thirdRowLayoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        thirdRowLayoutParams.addRule(RelativeLayout.BELOW, secondRow.getId());
        thirdRowLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
        thirdRowLayoutParams.setMargins((int) (10 * scale + 0.5f), 0, (int) (10 * scale + 0.5f), (int) (30 * scale + 0.5f));
        thirdRow.setGravity(Gravity.BOTTOM);
        thirdRow.setLayoutParams(thirdRowLayoutParams);

        TextView thirdRowTextView = new TextView(getContext());
        RelativeLayout.LayoutParams thirdRowTextViewLayoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams
                .WRAP_CONTENT);
        thirdRowTextViewLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_END);
        thirdRowTextView.setTypeface(Typeface.create("avenir", Typeface.BOLD));
        thirdRowTextView.setText("12:00AM");
        thirdRowTextView.setTextColor(Color.parseColor("#fff000"));
        thirdRowTextView.setLayoutParams(thirdRowTextViewLayoutParams);

        thirdRow.addView(thirdRowTextView);
        relativeLayout.addView(thirdRow);

        return relativeLayout;
    }

Эта функция вызывается для фрагмента onCreateView следующим образом: 

@Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.fragment_diary, container, false);

        RelativeLayout writeDiary = view.findViewById(R.id.writeDiary);
        writeDiary.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){
                Intent i=  new Intent(getActivity(),WriteDiary.class);
                startActivity(i);
            }



        });

        ImageView imageView= view.findViewById(R.id.listIcon);
        imageView.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){
                Intent i=  new Intent(getActivity(),ListThoughts.class);
                startActivity(i);
            }
        });

        scale = getContext().getResources().getDisplayMetrics().density;

        diary_mainLinearLayout = getActivity().findViewById(R.id.diary_mainLinearLayout);

        if (diary_mainLinearLayout != null) {
            diary_mainLinearLayout.addView(createCards());
        }

        return view;
    }

Признаюсь, я немного новичок в программировании Android.

ожидаемый результат должен выглядеть следующим образом:
