使用 WebView onTouchListener 链接到另一个 Activity - Android

Question

我有这个主页，我在其中设置了多个 webView。基本上这个想法很简单。我使用三个 webView，它们都从在线网站获取不同的内容。当他们点击网络视图时，它应该将他们带到另一个活动。然后剩下的交给我。我只需要使用 onTouchListener 将 Web 视图链接到另一个活动的帮助。

这是我的 Java 文件：查找 // THE CODE FOR THE OnTOUCHEVETN STARTS HERE! 行。这就是我正在尝试我的 webview 1 开始第二个活动的地方。我正在尝试使用它：Intent myIntentActivity1 = new Intent(this, ReadComments.Class); 但 java 给了我以下错误：

删除参数以匹配 'Intent()'

什么可能导致这个错误？

Answer 1

试试这个-

Intent myIntentActivity1 = new Intent(mainlogin.this, ReadComments.class);
startActivity(myIntentActivity1);

或者-

Intent myIntentActivity1 = new Intent(getBaseContext(), ReadComments.class);
startActivity(myIntentActivity1);
