降低gradle版本(参照下图)
使用cloneWithRows更新数据时, 如只更新该数据中的某一字段, 这条数据是不会被从新渲染, 需要整条记录替换更新才能被重新渲染, 数据结构如下:
cloneWithRows
var list = [ { name: 'dion', age: '18' }, { name: 'jack', age: '22' } ];
如果需要更新jack的age为20
jack
age
20
//这样不会被 ListView 重新渲染 list[1].age = 20; ds.cloneWithRows(list);
//整条记录更新才会被 ListView 重新渲染 list[1] = {name: 'jack', age: '20'}; ds.cloneWithRows(list);
