Android 调用onPictureTaken中的位图

如何在onPictureTaken方法中调用位图？。除非我重新启动手机，否则图像不会存储在多媒体资料中

请帮助重新安排代码

public static int getOrientation(Context context,Uri photoUri){
    Cursor cursor = context.getContentResolver().query(photoUri,new String[] {MediaStore.Images.ImageColumns.ORIENTATION},null,null,null);
    if(cursor.getCount()!=1){
        return -1;
    }
    cursor.moveToFirst();
    return cursor.getInt(0);

}

从未使用getCorrectlyOrientatedImage（）。请帮助我在哪里可以调用此函数

public static Bitmap getCorrectlyOrientatedImage(Context context, Uri photoUri)throws IOException{
    InputStream is=context.getContentResolver().openInputStream(photoUri);
    BitmapFactory.Options dbo = new BitmapFactory.Options();
    dbo.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(is,null,dbo);
    is.close();

    int rotatedWidth,rotatedHeight;
    int orientation = getOrientation(context,photoUri);

    if(orientation == 90 || orientation ==270){
        rotatedWidth=dbo.outHeight;
        rotatedHeight=dbo.outWidth;
    }else{
        rotatedWidth=dbo.outWidth;
        rotatedHeight=dbo.outHeight;
    }

    Bitmap srcBitmap;
    is = context.getContentResolver().openInputStream(photoUri);
    if(rotatedWidth > MAX_IMAGE_DIMENSION || rotatedHeight > MAX_IMAGE_DIMENSION ){
        float widthRatio = ((float) rotatedWidth) / ((float) MAX_IMAGE_DIMENSION);
        float heightRatio = ((float) rotatedHeight) / ((float) MAX_IMAGE_DIMENSION);
        float maxRatio = Math.max(widthRatio,heightRatio);

        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = (int) maxRatio;
        srcBitmap = BitmapFactory.decodeStream(is, null, options);
    }else{
        srcBitmap = BitmapFactory.decodeStream(is);
    }
    is.close();

    if(orientation > 0){
        Matrix matrix = new Matrix();
        matrix.postRotate(orientation);

        srcBitmap = Bitmap.createBitmap(srcBitmap,0,0,srcBitmap.getWidth(),srcBitmap.getHeight(),matrix,true);
    }
    return srcBitmap;
}


private PictureCallback mPicture = new PictureCallback() {


    public void onPictureTaken(byte[] data, Camera camera) {

        File pictureFile = getOutputMediaFile(MEDIA_TYPE_IMAGE);
        Log.d("onPictureTaken", "File is assigned to pictureFile");
        if (pictureFile == null) {
            Log.d(DEBUG_TAG, " Error creating a media file, check storage permissions:");
            return;
        }
       try {
            Bitmap bitmap=getCorrectlyOrientatedImage()
            FileOutputStream fos = new FileOutputStream(pictureFile);
            fos.write(data);
            fos.close();
            File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "SELFie");
            String path = mediaStorageDir.getPath() + File.separator + "IMG_Some_name.jpg";
            SCamera.this.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + path)));
        } catch (FileNotFoundException e) {
            Log.d("DG_DEBUG", "File not found: " + e.getMessage());
        } catch (IOException e) {
            Log.d("DG_DEBUG", "Error accessing file: " + e.getMessage());
        }

    }

};

在我重新启动手机之前，图像不会存储在SD卡中，而且存储的图像存储方向错误。若照片是纵向拍摄的，则图像存储在横向中。如何以正确的方向存储图像

private static File getOutputMediaFile(int type){
    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),"SELFie");
    if(!mediaStorageDir.exists()){
        if(!mediaStorageDir.mkdir()){
            Log.d(DEBUG_TAG,"Filed to create directory");
            return null;
        }
    }
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    File mediaFile;
    if (type == MEDIA_TYPE_IMAGE){
        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
                "IMG_"+ timeStamp + ".jpg");
    } else {
        return null;
    }

    return mediaFile;
}

我知道这个问题有点老了，但为了防止有人面临同样的问题，解决方案是将图像保存在背景线程中，如中所示

private PictureCallback mPicture=new PictureCallback（）{
公共void onPictureTaken（字节[]数据，摄像头）{
新建SaveImageTask（）.execute（数据）；
}
};
私有类SaveImageTask扩展了AsyncTask{
@凌驾
受保护的Void doInBackground（字节[]…数据）{
File pictureFile=getOutputMediaFile（媒体类型图像）；
Log.d（“onPictureTaken”，“文件被分配给pictureFile”）；
如果（pictureFile==null）{
d（DEBUG_标记，“创建媒体文件时出错，请检查存储权限：”）；
返回null；
}
试一试{
位图位图=getCorrectlyOrientatedImage（）
FileOutputStream fos=新的FileOutputStream（pictureFile）；
写入（数据）；
fos.close（）；
File mediaStorageDir=新文件（Environment.getExternalStoragePublicDirectory（Environment.DIRECTORY_PICTURES），“SELFie”）；
String path=mediaStorageDir.getPath（）+File.separator+“IMG\u Some\u name.jpg”；
SCamera.this.sendBroadcast（新的Intent（Intent.ACTION\u MEDIA\u SCANNER\u SCAN\u文件，Uri.parse（“文件：/”+path））；
}catch（filenotfounde异常）{
Log.d（“DG_调试”，“未找到文件：+e.getMessage（））；
}捕获（IOE异常）{
Log.d（“DG_调试”，“访问文件时出错：”+e.getMessage（））；
}
}
}

private PictureCallback mPicture = new PictureCallback() {

    public void onPictureTaken(byte[] data, Camera camera) {
        new SaveImageTask().execute(data);
    }

};


private class SaveImageTask extends AsyncTask<byte[], Void, Void> {

    @Override
    protected Void doInBackground(byte[]... data) {

        File pictureFile = getOutputMediaFile(MEDIA_TYPE_IMAGE);
        Log.d("onPictureTaken", "File is assigned to pictureFile");
        if (pictureFile == null) {
            Log.d(DEBUG_TAG, " Error creating a media file, check storage permissions:");
            return null;
        }

       try {
            Bitmap bitmap=getCorrectlyOrientatedImage()
            FileOutputStream fos = new FileOutputStream(pictureFile);
            fos.write(data);
            fos.close();
            File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "SELFie");
            String path = mediaStorageDir.getPath() + File.separator + "IMG_Some_name.jpg";
            SCamera.this.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + path)));
        } catch (FileNotFoundException e) {
            Log.d("DG_DEBUG", "File not found: " + e.getMessage());
        } catch (IOException e) {
            Log.d("DG_DEBUG", "Error accessing file: " + e.getMessage());
        }

    }

}
