Question

我已经看到here关于显示图片的答案，以及here关于Android中的上下文的答案，但我仍然很困惑在我的程序中使用它。这是我的程序的样子：

Mat drawImage;
Bitmap drawBitmap;
try {
    drawImage = Utils.loadResource(this, R.drawable.sample, Highgui.CV_LOAD_IMAGE_COLOR);
    drawBitmap = Bitmap.createBitmap(drawImage.cols(), drawImage.rows(), Bitmap.Config.ARGB_8888);
    Utils.matToBitmap(drawImage, drawBitmap);
    viewImage.setImageBitmap(drawBitmap);
} catch (IOException e) {
    e.printStackTrace();
}
// sample is filename of target image
// viewImage is ImageView object in .xml

我运行程序但是会弹出这些错误：

我尝试将上下文更改为MainActivity.this，但它仍然是错误的。我看到了Mat错误，因此我尝试将声明更改为Mat drawImage = new Mat()和Mat drawImage = new Mat(60, 60, CvType.CV_8UC3)，但没有任何运气。

我使用上下文错了吗？或者还有其他什么？任何建议都会有帮助。谢谢。
