具有u添加活動納入清單文件 –

是，艙單加入到質疑 –

下投票我！我是Android新手，謝謝:) –

我想，你錯了的），這條線，你正在使用中的setContentView（相同的佈局和每行的佈局

setContentView(R.layout.products);

用這種方式

setContentView(R.layout.XML_FILE_WHICH_CONTAIN_LISTVIEW);

編輯：

只要把

<?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" > 

    <ListView 
     android:id="@+id/Products" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" > 
    </ListView> 

</LinearLayout>

這個XML名稱這裏像

R.layout.products

如果你的意思是寫這個，那麼R.layout.XML_FILE_WHICH_CONTAIN_LISTVIEW無法解析。 –

@Dixit'products.xml'文件是包含'ListView'的文件。檢查OP;它已經發布... – Eric

如果你的意思是包含一個listview的佈局，那麼產品佈局就有一個！ –

您應該擴展ListActivity類。不是Activity類

試過，結果相同 –

然後將你的ListView id改爲「@android：id/list」 –

試過，結果相同:( –

嘗試改變：

<ListView 
    android:id="@+id/Products" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 
</ListView>
