Android应用程序:当点击应该显示随机图像的按钮时，Java崩溃

ImageView imageView = findViewById(R.id.imageView);
if (imageView != null) {
    imageView.setImageResource(randomImageResourceId);
}

int randomImageResourceId = getResources().getIdentifier("image_" + randomIndex, "drawable", getPackageName());
if (randomImageResourceId != 0) {
    imageView.setImageResource(randomImageResourceId);
} else {
    Log.e("ImageError", "Resource not found");
}

int[] imageResources = {R.drawable.image1, R.drawable.image2, R.drawable.image3};
int randomIndex = new Random().nextInt(imageResources.length);
imageView.setImageResource(imageResources[randomIndex]);

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2; // 缩放比例
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.large_image, options);
imageView.setImageBitmap(bitmap);
