如何让它像与大多数其他应用程序一样工作？比如，如果我们在WhatsApp中点击一个YouTube链接，那么特定的视频将在YouTube应用程序中打开，而不是在YouTube主页中打开。

Answer 1

LoadWeb("https://www.yoalfaaz.com");  // load the home page only once

使用getintent().getdata().tostring()获取从其他应用程序单击的URL（作为字符串)并使用此URL加载web视图，而不是硬编码URL。

如果没有从getdata()收到URL，请检查null并加载默认URL。

希望这能有所帮助。

LoadWeb("https://www.yoalfaaz.com");  // load the home page only once

String url = "https://www.yoalfaaz.com";
if(null != getIntent().getData()){
url = getIntent().getData().toString();
}
LoadWeb(url);
