安卓 java。算术异常：从pick gallery压缩图像时被零除

Question

从pick gallery压缩图像时出现错误java.lang.ArithmeticException: divide by zero。这是我的代码：

 public String compressImage(String filePath, String outputFilename) {

        Bitmap scaledBitmap = null;

        BitmapFactory.Options options = new BitmapFactory.Options();

        options.inJustDecodeBounds = true;
        Bitmap bmp = BitmapFactory.decodeFile(filePath, options);

        int actualHeight = options.outHeight;
        int actualWidth = options.outWidth;
        Log.i("INFO", "ActualHeight Input: " + actualHeight);
        Log.i("INFO", "ActualWidth Input: " + actualWidth);

        float maxHeight = 816.0f;
        float maxWidth = 612.0f;
        float imgRatio = actualWidth / actualHeight;
        float maxRatio = maxWidth / maxHeight;


       ............

        return outputFilename;
    }

林中的错误：float imgRatio = actualWidth / actualHeight;那么如何修复它呢

Answer 1

得到异常的事实表明被零除正在发生，并且options.outHeight返回零。你需要弄清楚为什么会这样。 如果Log.i("INFO", "ActualHeight Input: " + actualHeight);返回的不是null的内容，请提供更多详细信息
