public final static int TAKE_PHOTOS_CODE=1;

如果缺少拍照权限，就申请权限

if (ContextCompat.checkSelfPermission(TakePhotos_activity.this, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {

ActivityCompat.requestPermissions(TakePhotos_activity.this, new String[]{Manifest.permission.CAMERA},
TAKE_PHOTOS_CODE);
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

switch (requestCode) {
case TAKE_PHOTOS_CODE:

break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
