带按钮的Android应用程序：每个按钮需要一个webView吗？

我正在尝试开发一个简单的应用程序，有6个按钮和一个背景。 我需要这些按钮来打开应用程序内部的webView，每个按钮都有不同的URL。我发现的例子都不能解决我的问题。 只需一个webView类就可以做到这一点，还是每个按钮需要一个webView类

如果你能提供任何例子，我将不胜感激

依你的建议，我按下按钮时会有这种飞溅，Emad

您可以使用webview创建一个活动，单击任何按钮即可打开此活动并将url传递给它

你的按钮动作

Intent intent=new Intent(MainActivity.this,WebVIEWActivity.class);
        intent.putExtra("URl","YOUR_URL");
        startActivity(intent);

在您的WebviewActivity上

String url=getIntent().getExtras().getString("URl");

使用一个包含web视图的活动执行此操作

通过intent set string extra方法传递web视图url，如下所示：
