OneSignal - 帮我在现有的 webView 中打开 URL ...我很困惑
OneSignal - help me open URL within existing webView ... I'm so confused
我让某人为我创建了一个非常基本的 WebView 应用程序，其中包含 OneSignal 通知。该应用程序启动时会出现启动画面，然后主页上有两个按钮，将用户发送到不同的 URL - 在我下面的示例中，Google 和 Stack Overflow。
它工作正常，但我正在尝试进行更改以在点击通知时打开特定的 URL，但无法锻炼如何，尽管在这里阅读了大量内容和 OneSignal 文档。作为最后的手段，我想我会 post 我的代码，看看是否有人可以帮助这个新手进行应用程序编码！
基本上，我需要修复 ExampleNotificationOpenedHandler class 最底部的启动 URL 代码。我通过 OneSignal 发送 URL 作为附加数据，应用程序在 launchURL 变量中正确读取它（当我查看 logcat 时）。

我没有编写此代码，但如有任何帮助，我们将不胜感激。
像你一样使用按钮
if (launchURL != null) {
Log.i("OneSignalExample", "launchURL value: " + launchURL);
webView.clearHistory();
webView.loadUrl(launchURL);
home.setVisibility(View.GONE);
ll_Web.setVisibility(View.VISIBLE);
}
我认为设置 url 时不会创建 webview，如果可以的话，在 onStart 中添加动作侦听器
@Override
protected void onStart()
{
super.onStart();
OneSignal.startInit(this)
.setNotificationOpenedHandler(new ExampleNotificationOpenedHandler())
.init();
}
}
或至少在 setContentView(R.layout.main); 之后
喜欢这里
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
OneSignal.startInit(this)
.setNotificationOpenedHandler(new
ExampleNotificationOpenedHandler())
.init();
为了其他搜索类似问题的人的利益，我的工作代码如下。作为新手，我不确定它是否是最好的解决方案，但它对我一直在做的测试很有效。
