当html5视频全屏时，更改webview的返回方式

Question

我有一个加载报纸网站的应用程序。用户可以访问新闻并观看视频（如果有的话）。如果视频在按下后退按钮时处于全屏状态，则应用会转到新报纸主页而不是新闻。

活动代码：

@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代码：

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

覆盖在你的活动onBackPressed然后检查这样

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