无故膨胀类错误

Question

我有一个 xml 文件，它假设显示 15 个图像按钮，但直到 xml 文件中的图像按钮数量为 5 个或更低，它才能正常工作，但是对于更多数量的图像按钮，会引发此错误： java.lang.RuntimeException: 无法启动活动 ComponentInfo{com.example.ararat/com.example.ararat.Setwallpaper}: android.view.InflateException: Binary XML file line #35: Error inflating class

我的 xml 文件：

    <ScrollView 
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
  android:fillViewport="true" 
  xmlns:android="http://schemas.android.com/apk/res/android">
  <LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"

    >
     <ImageButton android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/wall_img_1"
         android:src="@drawable/wall1"
         android:layout_marginBottom="5dp"/>
     <ImageButton android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/wall_img_2"
         android:src="@drawable/wall2"
          android:layout_marginBottom="5dp"/>
      <ImageButton android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/wall_img_3"
         android:src="@drawable/wall3"
          android:layout_marginBottom="5dp"/>
        <ImageButton android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/wall_img_4"
         android:layout_marginBottom="5dp"
         android:src="@drawable/wall4"/>
         <ImageButton android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/wall_img_5"
         android:src="@drawable/wall5"
          android:layout_marginBottom="5dp"/>

   </LinearLayout>
  </ScrollView> 

注意：但是当我们添加更多（超过 5 个）具有相同图像的图像按钮（来自前 5 个图像按钮的图像，如“@drawable/wall5”）时，效果很好。 我尝试了相对布局和其他任何东西，但这个错误没有出现，我真的很困惑。

Answer 1

inflate 异常实际上并不是问题，而是真正来自布局中另一个更深层次的问题，然后将其包装在 InflateException 中。一个常见的问题是在尝试膨胀加载可绘制资源的图像视图时出现内存不足异常。如果其中一个资源具有高像素分辨率，则会占用大量内存，从而导致 inflate 异常。

因此，基本上要验证可绘制图像中的像素分辨率是否只是布局所需的最低要求。

Answer 2

由于图像过多，您的设备内存不足，请尝试使用

   android:largeHeap="true"

在 Menifest 文件的标签中为

     <application 
 android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"  >
