使用WebView onTouchListener鏈接到另一個活動 - Android

Question

我有這個主頁面，我設置了多個webViews。基本上這個想法很簡單。我使用三個webViews，他們都從一個在線網站獲取不同的內容。當他們點擊網絡視圖時，應該將他們帶到另一個活動。然後把剩下的留給我。我只需要使用onTouchListener將web視圖鏈接到另一個活動。

這是我的Java文件：查找// THE CODE FOR THE OnTOUCHEVETN STARTS HERE!行。那就是我嘗試使用我的webview 1開始第二個活動的地方。我試圖用這個：Intent myIntentActivity1 = new Intent(this, ReadComments.Class);但Java給了我以下錯誤：

什麼導致這個錯誤？

Answer 1

嘗試這個 -

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

或 -

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