延展WebViewClient打电话onPageFinish()如下：mWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
// do your stuff here
}});

这并不是百分之百准确。如果一个页面中有几个iframes，那么就会有多个onPageFinish(和onPageStarted)。如果您有几个重定向，它也可能失败。这种方法解决了(几乎)所有的问题：boolean loadingFinished = true;boolean redirect = false;mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) {
if (!loadingFinished) {
redirect = true;
}
loadingFinished = false;
webView.loadUrl(urlNewString);
return true;
}
@Override
public void onPageStarted(WebView view, String url) {
loadingFinished = false;
//SHOW LOADING IF IT ISNT ALREADY VISIBLE
}
@Override
public void onPageFinished(WebView view, String url) {
if (!redirect) {
loadingFinished = true;
//HIDE LOADING IT HAS FINISHED
} else {
redirect = false;
}
}});最新情况：根据文档：当嵌入式框架的内容发生变化时，即单击目标为iframe的链接时，将不会调用onPageStarted。我在Twitter上发现了一个特殊的例子，在Twitter上，只有一个页面被调用，逻辑有点混乱。为了解决这个问题，我在X秒之后添加了一个预定任务来删除加载。这并不是所有其他情况下都需要的。更新2:现在，使用当前的AndroidWebView实现：boolean loadingFinished = true;boolean redirect = false;
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(
WebView view, WebResourceRequest request) {
if (!loadingFinished) {
redirect = true;
}
loadingFinished = false;
webView.loadUrl(request.getUrl().toString());
return true;
}
@Override
public void onPageStarted(
WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
loadingFinished = false;
//SHOW LOADING IF IT ISNT ALREADY VISIBLE
}
@Override
public void onPageFinished(WebView view, String url) {
if (!redirect) {
loadingFinished = true;
//HIDE LOADING IT HAS FINISHED
} else {
redirect = false;
}
}
});

我非常喜欢@NeTeInSteiN(和@Polen)解决方案，但我会用一个计数器来实现它，而不是多个布尔人或州观察者(只是另一种口味，但我认为这可能有共同之处)。它确实有一个JS的细微差别，但我觉得逻辑更容易理解。private void setupWebViewClient() {
webView.setWebViewClient(new WebViewClient() {
private int running = 0; // Could be public if you want a timer to check.
@Override
public boolean shouldOverrideUrlLoading(WebView webView, String urlNewString) {
running++;
webView.loadUrl(urlNewString);
return true;
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
running = Math.max(running, 1); // First request move it to 1.
}
@Override
public void onPageFinished(WebView view, String url) {
if(--running == 0) { // just "running--;" if you add a timer.
// TODO: finished... if you want to fire a method.
}
}
});}
