这是通过调用相机意图从 jpeg.i 中提取标签的代码。单击照片后,我应该将其发送到下面的代码以提取信息。如何将点击的照片作为参数发送?
Bundle bundle = getIntent().getExtras();
if(null != bundle)
{
String filepath = bundle.getString(FILE_PATH_KEY);
try
{
ExifInterface exif = new ExifInterface(filepath);
StringBuilder builder = new StringBuilder();
builder.append("Date & Time: " + getExifTag(exif,ExifInterface.TAG_DATETIME) + "\n\n");
builder.append("Flash: " + getExifTag(exif,ExifInterface.TAG_FLASH) + "\n");
builder.append("Focal Length: " + getExifTag(exif,ExifInterface.TAG_FOCAL_LENGTH) + "\n\n");
builder.append("GPS Datestamp: " + getExifTag(exif,ExifInterface.TAG_FLASH) + "\n");
builder.append("GPS Latitude: " + getExifTag(exif,ExifInterface.TAG_GPS_LATITUDE) + "\n");
builder.append("GPS Latitude Ref: " + getExifTag(exif,ExifInterface.TAG_GPS_LATITUDE_REF) + "\n");
builder.append("GPS Longitude: " + getExifTag(exif,ExifInterface.TAG_GPS_LONGITUDE) + "\n");
builder.append("GPS Longitude Ref: " + getExifTag(exif,ExifInterface.TAG_GPS_LONGITUDE_REF) + "\n");
builder.append("GPS Processing Method: " + getExifTag(exif,ExifInterface.TAG_GPS_PROCESSING_METHOD) + "\n");
builder.append("GPS Timestamp: " + getExifTag(exif,ExifInterface.TAG_GPS_TIMESTAMP) + "\n\n");
builder.append("Image Length: " + getExifTag(exif,ExifInterface.TAG_IMAGE_LENGTH) + "\n");
builder.append("Image Width: " + getExifTag(exif,ExifInterface.TAG_IMAGE_WIDTH) + "\n\n");
builder.append("Camera Make: " + getExifTag(exif,ExifInterface.TAG_MAKE) + "\n");
builder.append("Camera Model: " + getExifTag(exif,ExifInterface.TAG_MODEL) + "\n");
builder.append("Camera Orientation: " + getExifTag(exif,ExifInterface.TAG_ORIENTATION) + "\n");
builder.append("Camera White Balance: " + getExifTag(exif,ExifInterface.TAG_WHITE_BALANCE) + "\n");
builder = null;
}
catch (IOException e)
{
e.printStackTrace();
}
}
拍摄照片的代码
Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
startActivityForResult(captureIntent, CAMERA_CAPTURE);
