我有这个主页面，我设置了多个webViews。基本上这个想法很简单。我使用三个webViews，所有这些都从在线网站获取不同的内容。他们点击Web视图的那一刻，应该将他们带到另一个活动。然后把剩下的留给我。我只需要帮助您使用onTouchListener将Web视图链接到另一个活动。
这是我的Java文件：查找// THE CODE FOR THE OnTOUCHEVETN STARTS HERE!行。这是我尝试我的webview 1开始第二个活动的地方。我试图使用它：Intent myIntentActivity1 = new Intent(this, ReadComments.Class);但是java给了我以下错误：
删除与'Intent（）'匹配的参数

可能导致此错误的原因是什么？
答案 0 :(得分：2)
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);
