Question

我已经创建了android webview应用程序。

但网页上的链接或按钮无效。

我可以说它没有正确加载。

您可以在此处找到MainActivity.java

我们如何解决问题。

Answer 1

由于您的网站需要javascript，因此您应该在网络视图中启用javascript执行：

 webview.getSettings().setJavaScriptEnabled(true);

另见documentation

更新：您可以通过添加以下内容来取消警告消息Warning: Using setJavaScriptEnabled can introduce XSS vulnerabilities into you application：

 @SuppressLint("SetJavaScriptEnabled") // add this
 @Override
 protected void onCreate(Bundle savedInstanceState) {

在onCreate方法之上。
