android 6.0  简单的动态获取权限

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);}

获取权限之后的动作

@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {    switch (requestCode) {        case TAKE_PHOTOS_CODE:                        break;        default:            super.onRequestPermissionsResult(requestCode, permissions, grantResults);    }}
