拍摄照片我正在使用安装在设备上的相机。 这张照片保存在画廊内部,但是总是水平保存。
我该如何解决?
图库中的图片以错误的方向保存
这是当点击按钮 “添加照片” 的意图:
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = null;
photoURI = galleryAddPic();
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
这是方法createImageFile()
:
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
imageFileName = "JPG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
最后,这是方法galleryAddPic()
:
private Uri galleryAddPic(){
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
return contentUri;
}
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
将照片插入到图库后,我可以根据需要旋转图像。 但是在图库中图像旋转不好。
所以我想用正确的方向将图像保存在画廊中。
谢谢!
我已经在imageview.and函数中显示图像,但我需要旋转位图然后将其存储在库 – Ibernato933
@lbernato检查更新的答案。 –
是的,但在methos addGalleryPic之前,如果我调用decodeBitmap(path),sull中的位图。拍摄照片时,如何检索位图? – Ibernato933
