Question

我目前正在制作一个使用动态布局的应用程序。这是我第一次这样做，而我只是为了学习它而做。我设法让它加载大部分数据并正确显示，但我遇到第一项问题。由于某种原因，它会跳过它并从第2项开始。它将其加载到变量中但由于某种原因未显示。我相信它与布局参数有关，但我找不到它的行为方式。

这是它的外观（请注意，它应该以141- ...项目开始。它被加载到变量tho但未显示）

这是我用来根据变量

加载项目的代码

for (int i = 0; i <= id_l; i++)
            {
                RelativeLayout container = (RelativeLayout)findViewById(R.id.popisLinija);
                View item_layout = getLayoutInflater().inflate(R.layout.item_layout, null);
                Integer l = id_l;
                Log.d("id length: ", l.toString());
                Log.d("ID: ", id[i].toString());
                Log.d("Linija br: ", broj_linije[i]);
                Integer i2 = i;
                Log.d("i= ", i2.toString());

                item_layout.setId(i);
                item_layout.setTag("View");

                final Integer h = item_layout.getId();

                // fill in any details dynamically here
                assert item_layout != null;
                TextView textView = (TextView) item_layout.findViewById(R.id.item_text);

                if(broj_linije[i].equals("000"))
                {
                    textView.setText(naziv_linije[i]);
                }
                else
                {
                    textView.setText(broj_linije[i] + " - " + naziv_linije[i]);
                }


                textView.setTag("Text");


                RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
                if(i == 0)
                {
                    if (rlp != null) {
                        rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, container.getId());
                    }
                }
                if(i > 0)
                {
                    if (rlp != null) {
                        rlp.addRule(RelativeLayout.BELOW, i-1);
                    }
                }


                FrameLayout item_button = (FrameLayout) item_layout.findViewById(R.id.item_button);
                item_button.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View arg0)
                    {
                        Integer a =  h;
                        Toast.makeText(getApplicationContext(), "Clicked me", Toast.LENGTH_SHORT).show();
                        Log.d("clicked", h.toString());
                    }
                });

                item_layout.setLayoutParams(rlp);
                container.addView(item_layout);
            }

我已检查项目是否已加载

有人能帮助我解决我在这里做错了什么吗？我会非常感激，我在这个上面花了很多时间尝试各种没有结果的东西。
