我将图像存储在可绘制文件夹中，其大小为 1mb，分辨率为 992x9000，我的代码：

ImageView jpgView = (ImageView) findViewById(R.id.surahShow);
Uri path = Uri.parse("android.resource://com.android.ta/" + R.drawable.myimage);
jpgView.setImageURI(path);

应用程序运行并强制关闭

这是我的 LogCat：

然后我尝试更改我的代码：

public static int calculateInSampleSize(
            BitmapFactory.Options options, int reqWidth, int reqHeight){

        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 2;

        if (height/2 < reqHeight || width/2 < reqWidth) {
            final int heightRatio = Math.round((float) height / (float) reqHeight);
            final int widthRatio = Math.round((float) width / (float) reqWidth);
inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
            }
        return inSampleSize;
    }

    public static Bitmap decodeSampleBitmapFromResource(Resources res, int resId,
            int reqWidth, int reqHeight) {

        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeResource(res, resId, options);
        options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
        options.inJustDecodeBounds = false;
        return BitmapFactory.decodeResource(res, resId, options);
        }
jpgView.setImageBitmap(decodeSampleBitmapFromResource(getResources(), R.drawable.myimage, 100, 100));

但仍然强制关闭

将图像加载到 Bitmap 对象时出现奇怪的内存不足问题

但问题是，我无法用我使用的代码调整他们的代码

我在 android 2.3.1 上做

有人可以帮忙吗

您可以使用http://loopj.com/android-smart-image-view/上的 SmartImageView 库。学习并使用它。
