鸿蒙跳转至系统设置

let context = getContext(this) as common.UIAbilityContext; // UIAbilityContext
let want: Want = {
    deviceId: '', // deviceId为空表示本设备
    bundleName: 'com.huawei.hmos.settings',
    abilityName: 'com.huawei.hmos.settings.MainAbility',
    uri:"xxx"
};

uri为具体页面 例如set_input可以跳转至系统设置的输入法界面

context.startAbility(want)
