使用CameraX保存图像时出现“错误的偏移量可能导致无限循环”错误

编程问答 2022-06-12

问题描述

有人可以帮我解决这些错误。我试图在捕获图像后保存图像，但是它不起作用，并不断给我这些关于标签为ULONG的错误，并且错误的偏移量可能会导致无限循环。我不确定错误在哪里，我使用File类错了吗？还是getExternalDirectory部分？

我认为它来自此函数，因为它是处理文件的地方。

//take photo function
private void takePhoto() {

    // Create time-stamped output file to hold the image
    File photoFile;
    photoFile = new File(Environment.getExternalStorageDirectory(),"IMG_${System.currentTimeMillis()}.jpg");

    // Create output options object which contains file + Metadata
    ImageCapture.OutputFileOptions outputoptions = new ImageCapture.OutputFileOptions.Builder(photoFile).build();


    imageCapture.takePicture(outputoptions,ContextCompat.getMainExecutor(this),new ImageCapture.OnImageSavedCallback () {
        @Override
        public void onImageSaved(@NonNull ImageCapture.OutputFileResults outputFileResults) {
            Toast.makeText(MainActivity.this,"Photo Capture Succeeded: "+ outputFileResults,Toast.LENGTH_SHORT).show();
        }
        @Override
        public void onError(@NonNull ImageCaptureException error) {
            Toast.makeText(MainActivity.this,"Photo capture Failed: "+ error,Toast.LENGTH_SHORT).show();
        }
    });
}
