在Android中加載動態佈局

我目前正在製作一個使用動態佈局的應用程序。這是我第一次做這個，我只是爲了學習它而做的。我設法讓它加載大部分數據並正確顯示，但我遇到了第一項問題。由於某種原因，它跳過它並從第二項開始。它將它加載到一個變量中，但由於某種原因它未被顯示。我相信它與佈局參數有關，但我找不到這樣做的理由。在Android中加載動態佈局

這是它的外觀（注意，它應該141-開始......項目，它被裝載到一個變量壽卻未顯示）

enter image description here

這是我的代碼中號使用根據

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); 
      }

我已經檢查了變量加載的項目，如果該項目被裝載

任何人都可以幫我解決我在這裏做錯了什麼？我將不勝感激，我在這個嘗試各種各樣的東西沒有結果的時候失去了幾個小時。

嘗試這種方式，希望這將幫助你......

XML代碼

activity_main

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <ImageView 
     android:layout_width="match_parent" 
     android:layout_height="180dp" 
     android:src="@drawable/ic_launcher" 
     android:adjustViewBounds="true"/> 

    <ScrollView 
     android:layout_width="match_parent" 
     android:layout_height="0dp" 
     android:layout_weight="1"> 

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

     </LinearLayout> 
    </ScrollView> 

</LinearLayout>

活動代碼

MainActivity

public class MainActivity extends Activity { 

    private LinearLayout lnrDynamicItem; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     lnrDynamicItem = (LinearLayout) findViewById(R.id.lnrDynamicItem); 

     for (int i = 0; i <= id_l; i++) 
     { 
      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"); 


      TextView textView = new TextView(this); 
      textView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 
      textView.setId(i+1); 

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


      textView.setTag(textView.getId()); 



      textView.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) 
       { 
        Integer a = (Integer) view.getTag(); 
        Toast.makeText(getApplicationContext(), "Clicked me", Toast.LENGTH_SHORT).show(); 
        Log.d("clicked", h.toString()); 
       } 
      }); 

      lnrDynamicItem.addView(textView); 
     } 

    } 

}

謝謝。我採取了你的方法，並將線性佈局添加到現有的相對佈局，並刪除了添加子規則的部分代碼。現在它正確顯示所有項目。 –
