【问题描述】：

我已经在 android 中加载了多个 webview，我知道 webview 加载所用的时间是“onPageStarted”和“onPageFinished”之间的差异。但是我有多个 webview 如何计算加载的总 webviews 时间？

【参考方案1】：

class PerfIDs

    public long time;
    public String url;
    PerfIDs(long time, String url)
    
        this.time = time;
        this.url = url;
    
    public Long getUrl(String url) 
        return time;
    
;

ArrayList<PerfIDs> appPerformanceTime = new ArrayList<PerfIDs>();
long startTime;
long endTime;
long firststartTime;
long lastendTime;
boolean startHold = true;
public void onPageStarted(WebView view, String url, Bitmap favicon) 
  startTime = System.currentTimeMillis();
  if(startHold)
    firststartTime = startTime;
    startHold = false;
  
  appPerformanceTime.add(new PerfIDs(startTime,url));
  super.onPageStarted(view, url, favicon);

public void onPageFinished(WebView view, String url) 
  lastendTime = endTime = System.currentTimeMillis();
  int lastIndex = 0;
  for (int i = 0; i < appperftime.size(); i++) 
    String val = appperftime.get(i).url;
    if(url.equals(val))
       System.out.println("url--"+url+"time-taken"+(endTime - appperftime.get(i).time));
       lastIndex = i;
     
   
if(lastIndex == appperftime.size()-1)
   System.out.println("total time taken --"+(lastendTime - firststartTime));

   super.onPageFinished(view, url);
