的确是这样，下拉刷新一次后，之后往上滑动一下，再次下拉才能拉下来，无法直接2次下拉刷新

确定吗，我怎么才能复现呢

listAttribute:(attr)=>{ attr.height = WindowHeight },

这个设置去掉就正常了

这个设置怎么去掉，源码里去掉？

这个设置怎么去掉，源码里去掉？

ListView({ lazyDataSource: this.dataSource, itemLayout: (item, index) => this.itemLayout(item, index), //条目布局 controller: this.controller, //控制器，负责关闭下拉和上拉 onRefresh: () => { this.loadDataSource() }, // onLoadMore:()=>{ // this.controller.finishLoadMore(true) // }, // listAttribute:(attr)=>{ // attr.height = WindowHeight - Number(AppStorage.get('statusBarHeightVp')) - 44 // }, lazyCachedCount:3 }) .layoutWeight(1)

使用中去掉了，设置后就不行
