我想在一个 webview 中加载多个 url 例如 如果我点击图片 1，那么我想打开 url 1 如果我点击图片 2，那么我想打开 url 2 像这样每个按钮应该有不同的网址

这里我只加载了一个 URL，但我想使用 if 语句再添加三个 URL，但我无法更改。请任何人帮助我 提前致谢

为你的 imageViews 使用监听器。

imageButton1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mWebView.loadUrl("your url");
            }
        });
