我正在开发一个 Android 应用程序来将一些图像加载到模拟器，但它失败并出现以下错误：

11-07 19:38:51.596: E/dalvikvm-heap(322): 73670400-byte external
allocation too large for this process.

11-07 19:38:51.596: E/GraphicsJNI(322): VM won't let us allocate

我的 Java 代码在下面发生错误的地方。我曾经System.out.println调试过这个问题。

public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub

    System.out.println("11");
    ImageView imageView = new ImageView(context);
    System.out.println("12");


    imageView.setImageResource(imageIDs[position]);
    System.out.println("13");
    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    System.out.println("14");
    imageView.setLayoutParams(new Gallery.LayoutParams(150, 220));
    System.out.println("15");
    imageView.setBackgroundResource(itemBackGround);

    System.out.println("16");

    return imageView;
}

如果您能提供帮助，我将不胜感激。谢谢。

在调用垃圾回收后尝试捕捉期望并重试

public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        System.out.println("11");
        ImageView imageView = new ImageView(context);
        System.out.println("12");
        try {

            imageView.setImageResource(imageIDs[position]);
            System.out.println("13");
            imageView.setScaleType(ImageView.ScaleType.FIT_XY);
            System.out.println("14");
            imageView.setLayoutParams(new Gallery.LayoutParams(150, 220));
            System.out.println("15");
            imageView.setBackgroundResource(itemBackGround);


    } catch (OutOfMemoryError e) {
            // run your image cache clean up here if you have one
            // call sys gc
    System.gc();        

            imageView.setImageResource(imageIDs[position]);
            System.out.println("13");
            imageView.setScaleType(ImageView.ScaleType.FIT_XY);
            System.out.println("14");
            imageView.setLayoutParams(new Gallery.LayoutParams(150, 220));
            System.out.println("15");
            imageView.setBackgroundResource(itemBackGround);
    }

        System.out.println("16");

        return imageView;
}

显然图像文件是 70 兆字节，这将是你的问题。这比 android 应用程序允许的堆大小要大得多。
