Question

我有一个xml文件，假设显示15个图像按钮，但是直到xml文件中的图像按钮数量为5或更低才能正常工作，但是对于更多数量的图像按钮，会出现此错误： java.lang.RuntimeException：无法启动活动ComponentInfo {com.example.ararat / com.example.ararat.Setwallpaper}：android.view.InflateException：二进制XML文件行＃35：错误导致类

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”）工作正常。我试过相对布局和其他任何东西，但这个错误没有，我真的很困惑。

Answer 1

膨胀异常实际上并不是问题，但实际上来自布局中的另一个更深层次的问题，然后将其包装在InflateException中。一个常见问题是在尝试加载加载可绘制资源的imageview时出现内存不足异常。如果其中一个资源具有较高的像素分辨率，则需要大量内存才会导致膨胀异常。

因此，基本上验证drawables图像中的像素分辨率只是布局所需的最小值。

Answer 2

由于许多图片，您的设备内存不足，请尝试使用

   android:largeHeap="true"

在Menifest文件的标签中

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

无理由地膨胀类时出错
