我的功能无法将照片保存在手机图库中。他将照片保存在DCIM

Question

这里是保存照片的功能。我想把这张照片放在画廊里。

public File getOutputMediaFile() { 
      File dir2 = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "dentafy"); 
      String timeStamp = new SimpleDateFormat("yyMMdd_HHmmss", Locale.getDefault()).format(new Date()); 
      String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString(); 
      String filename = File.separator + "2IMG_" + timeStamp + ".jpg"; 
      Log.d("getOutMediaFile", filename); 
      File c = new File(dir2.getPath(), filename); 
      filepath = filename; 
      picturepath(); 


      return c; 

     } 

     public String picturepath() 
     { 
      return filepath; 
     }

前端和rear-摄像机之间的区别是，由后者拍摄的照片要大得多，这是不可能的将其以全尺寸转换为Bitmap以在ImageView中显示它：您跨越应用程序内存限制。您可以增加应用程序允许的内存量，但更好 - 缩小位图的大小。在这里您有两种选择：将后置摄像头的图片尺寸设置得较小（最好适合图片视图的尺寸），或者在decodeFile()中缩小位图。
