尝试一下： 1）在您的应用中打开清单文件夹

2）添加

/** * Returns a collection of items * * @param \Illuminate\Support\Collection $list * @param int $prev * * @return \Illuminate\Support\Collection */ public function getSortOrder( $list, $prev = 0 ){ $result = collect(); $with_prevs = $list->filter( function( $item ) use ( $prev ){ return $item->data[ 'prev' ] == $prev; } ); $list = $list->diff( $with_prevs ); if( $with_prevs ->count() > 0 ){ foreach( $with_prevs as $with_prev ){ $result->push( $with_prev ); if( $list->count() > 0 ){ $result->concat( $this->getSortOrder( $list, $with_prev->id ) ); } } } return $result; }

3）添加<uses-permission android:name="android.permission.INTERNET" />
