的ImageButton與JPEG源引起InflateException

Question

我有15 imageButtons，他們的src屬性被設置爲JPEG圖片：

<ImageButton 
     android:id="@+id/button01" 
     android:layout_width="fill_parent" 
     android:layout_height="match_parent" 
     android:layout_weight="0.2" 
     android:padding="5dp" 
     android:scaleType="fitCenter" 
     android:adjustViewBounds="true" 
     android:background="@drawable/button_state" 
     android:src="@drawable/agri_b" /> 

當我運行我的應用程序得到InflateException錯誤。我試圖將Activity班改爲FragmentActivity班，但沒有任何變化。我猜想我的JPEG圖片大小有問題。不過，我最大的圖片大小爲217 KB。 這裏是我得到的錯誤：

任何幫助，將不勝感激。

EDIT-1

要檢查是否錯誤是對圖片的大小有關，我刪除了所有的圖片來源從ImageButtons卻不料我再次得到錯誤！認真的問題在哪裏？

Answer 1

嘗試

android:layout_width="0dp" 

（如果圖片是其父視圖內橫向顯示） 或

android:layout_height="0dp" 

（如果他們其父內部垂直顯示）。如果您使用layout_weight，則圖像的寬度或高度應始終爲0dp。

Answer 2

可能是它的問題與您的代碼

<ImageButton 
    android:id="@+id/button01" 
    android:layout_width="fill_parent" 
    android:layout_height="match_parent" 
    android:layout_weight="0.2" 
    android:padding="5dp" 
    android:scaleType="fitCenter" 
    android:adjustViewBounds="true" 
    android:background="@android:color/transparent" 
    android:src="@drawable/ic_launcher" /> 

嘗試用這種code..if這個works..then問題可能be..you是在兩個背景設置繪製以及SRC ..這就是爲什麼你會得到錯誤..
