这是保存照片的功能。我想把照片放在画廊里。
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;
}

前置摄像头和后置摄像头之间的区别在于后者拍摄的图像要大得多，并且无法将其全尺寸转换为位图以在ImageView中显示它：您跨越了应用程序内存限制。您可以增加应用程序允许的内存量，但更好 - 减小位图的大小。在这里，您有两种选择：将后置摄像头的图片大小设置得更小（最好适合图像视图的大小），或者在decodeFile()中缩小位图。
