有一次，我尝试重新调整图像大小，我也遇到了同样的问题，我使用了下面的代码，您可以根据自己的需要进行修改，

public Bitmap custom_SizedImage(String intent_data2) {

        Options options = new Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(intent_data2, options);
        double sampleSize = 0;
        Boolean scaleByHeight = Math.abs(options.outHeight - targetHeight) >= Math
                .abs(options.outWidth - targetWidth);

        if (options.outHeight * options.outWidth * 2 >= 1638) {
            sampleSize = scaleByHeight ? options.outHeight / targetHeight
                    : options.outWidth / targetWidth;
            sampleSize = (int) Math.pow(2d,
                    Math.floor(Math.log(sampleSize) / Math.log(2d)));
        }
        options.inJustDecodeBounds = false;
        options.inTempStorage = new byte[128];
        while (true) {
            try {
                options.inSampleSize = (int) sampleSize;
                           // here you can do you Decode process
                //mBitmap = BitmapFactory.decodeFile(intent_data2, options);

                break;
            } catch (Exception ex) {
                try {
                    sampleSize = sampleSize * 2;
                } catch (Exception ex1) {

                }
            }
        }
        return scaledBitmap;

    }
