Answer 1

DIdü嘗試使用MediaStore.ACTION_IMAGE_CAPTURE來代替？它適用於我。我能夠拍攝照片並獲得URI。下面是代碼

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     String fileName = TravellerUtils.generateUniqueID() 
       + IMAGE_FILE_EXT; 
     File file = new File(Environment.getExternalStorageDirectory(), 
       TravellerConstants.IMAGE_PATH + fileName); 
     Uri outputFileUri = Uri.fromFile(file); 
     intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
     startActivityForResult(intent, TAKE_PICTURE); 

Answer 2

這個意圖MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA可以拍攝幾張照片並將其發送到庫，但是，你不能抓住它拍照之後。它也可以讓你拍攝視頻，但你也無法捕捉。

我建議你分別用兩個意圖拍照和錄像。

;畫面：

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    File imagesFolder = new File(Environment.getExternalStorageDirectory(), "Camera"); 
    imagesFolder.mkdirs(); 
    Random random = new Random(); 
    int n = random.nextInt(10000); 
    File image = new File(imagesFolder, "YourApplication" + n + ".jpg"); 
    photoUri = Uri.fromFile(image); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri); // set the image file name 

    // start the image capture Intent 
    startActivityForResult(intent, Constants.CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); 

和視頻：

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); 

fileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO); // create a file to save the video 
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name 

intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // set the video image quality to high 

// start the Video Capture Intent 
startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);
