"android.view.View không thể được đúc để android.view.ViewGroup" ngoại lệ

Question

tôi đang làm việc trên một ứng dụng Android và tôi đã thêm một file xml bố trí mà phải là một đoạn sau:

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

    <ImageView 
     android:id="@+id/imgTile" 
     android:src="@drawable/tile_background" 
     android:contentDescription="@string/CD_TILE_BACKGROUND_IMAGE" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
    </ImageView> 

</View> 

Khi tôi cố gắng quay lại bố cục đồ họa trong Eclipse, tôi nhận ngoại lệ này trong nhật ký lỗi:

Có thể giúp tôi với ngoại lệ này không?

Answer 1

Tôi nghĩ rằng bạn nên sử dụng

<?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" > 

    <ImageView 
     android:id="@+id/imgTile" 
     android:src="@drawable/tile_background" 
     android:contentDescription="@string/CD_TILE_BACKGROUND_IMAGE" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
    </ImageView> 

</LinearLayout > 

như Xem không có bất kỳ chức năng như add (other_view) bạn có thể thêm một cái nhìn trong ViewGorup ....
