當html5視頻全屏時，更改webview的返回方式

Question

我有一個加載報紙網站的應用程序。用戶可以訪問新聞並觀看視頻（如果有的話）。如果視頻在按下後退按鈕時處於全屏狀態，則應用會轉到新報紙主頁而不是新聞。

活動代碼：

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    // Check if the key event was the Back button and if there's history 
    if (QuickstartPreferences.getIfIsInFullScreen(this)) { 
     Log.i("myApp", "is in fullScreen"); 
    } 
    ... 
    if (myWebView.canGoBack()) { 
     myWebView.goBack(); 
    } 
} 

QuickstartPreferences代碼：

public static boolean getIfIsInFullScreen(Activity myActivityReference) { 
    boolean fullScreen = (myActivityReference.getWindow().getAttributes().flags & WindowManager.LayoutParams.FLAG_FULLSCREEN) != 0; 
    return fullScreen; 
} 

Answer 1

覆蓋在你的活動onBackPressed然後檢查這樣

if (webView.canGoBack()){ 
    // your bussiness logic goes here 
     } else { 
     super.onBackPressed() 
     }
