當我嘗試調試我的應用程序時,當我在佈局中包含此xml時,我得到一個runtimeexception。我看不出有什麼問題,你能嗎? 我正在使用android eclipse插件,eclipse 3.5.2,最新的android插件和最新的java 6 ... 21在winxppro 32位sp3上 謝謝。在這個android佈局xml塊中有什麼bug

<ImageButton android:id="@+id/map_button" 
    android:src="@drawable/bot_map" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    /> 

<ImageButton android:id="@+id/filter_button" 
    android:src="@drawable/bot_filter" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    /> 

<ImageButton android:id="@+id/sort_button" 
    android:src="@drawable/bot_sort" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    /> 

<ImageButton android:id="@+id/prev_button" 
    android:src="@drawable/bot_arrow_prev" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    /> 


<ImageButton android:id="@+id/next_button" 
    android:src="@drawable/bot_arrow_next" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    /> 

我也得到這些異常在同一時間:

我們可以看到該代碼片段的封閉佈局嗎? – blindstuff 2010-10-29 20:51:12

如果這是您的整個XML文件,那麼您缺少一個根元素 - 包含所有這些按鈕的佈局。如果這不是全部 - 請完整發布您的XML – Asahi 2010-10-29 22:44:39
