哪里用代码考过去就行

 final PermissionDialog dialog = new PermissionDialog( this, R.style.Theme_AppCompat_Dialog );

                dialog.setOnClickCallbackListener( new PermissionDialog.OnClickCallbackListener( ) 
                    @Override
                    public void onClickLeftBtn() 
                        PreferencesUtils.saveLong( AppConstants.SP_SAVE_FILE_NAME, "onetime", LoginActivity.onetime );
                        dialog.cancel( );

                    

                    @Override
                    public void onClickRightBtn() 
                        PreferencesUtils.saveLong( AppConstants.SP_SAVE_FILE_NAME, "onetime", LoginActivity.onetime );
                        doPermission( );
                    
                 );
                dialog.show( );
