如何在nativescript中激活另一个开关时禁用自动切换

<Switch id="switch1" checked="false" />
<Switch id="switch2" checked="false" />

const switchModule = require("tns-core-modules/ui/switch");

function onSwitch1Loaded(args) {
    const switch1 = args.object;
    switch1.on("checkedChange", (args) => {
        const isChecked = args.object.checked;
        const switch2 = switchModule.getViewById("switch2");
        switch2.isEnabled = !isChecked;
    });
}

exports.onSwitch1Loaded = onSwitch1Loaded;

<Switch id="switch1" checked="false" loaded="onSwitch1Loaded" />
