更改android中listview中的baseadapter中linearlayout的高度和寬度運行時？

Question

我想改變的LinearLayout的高度在列表視圖中使用我如何可以改變該佈局的高度和寬度，我會在這裏把我的代碼，但沒有改變的LinearLayout如何做到這一點

首頁的高度。 XML

<LinearLayout  
     android:id="@+id/homelistlayout1" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
              > 
      <ListView 
      android:id="@+id/listadd1"

刪除烏爾XML使用機器人android_weight屬性：layout_height = 「120dp」 烏爾願望

實施例：

  <LinearLayout android:id="@+id/layoutadvertise" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:padding="2dp" 
       > 



    </LinearLayout>
