来自Android应用程序的错误OOM

Question

我正在开发一个Android应用程序，以将某些图像加载到模拟器中，但是在以下错误时失败：

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
73670400 bytes

11-07 19:38:51.926: E/AndroidRuntime(322):  at
android.graphics.Bitmap.createBitmap(Bitmap.java:435)

我的Java代码在此发生错误。我使用System.out.println调试问题。

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，我真的很感激。谢谢。

呼叫垃圾收集后尝试捕捉到的投放和重试

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，这是您的问题。这比允许堆尺寸大得多。
