android - 如何从 CustomTabsClient 获取 Url 更改

Question

如何在页面变化时获取url，使用CustomTabsClient？

例如 WebView 有一个方法:

@Override
public void onPageStarted(WebView view, String url, Bitmap favicon){}

CustomTabs 我需要一个类似的方法。

我找到了这个:

mClient.newSession(new CustomTabsCallback(){
    @Override
    public void onNavigationEvent(int navigationEvent, Bundle extras) {
        super.onNavigationEvent(navigationEvent, extras);
    }

    @Override
    public void extraCallback(String callbackName, Bundle args) {
        super.extraCallback(callbackName, args);
    }
});

但我不确定这是否是我需要的。

How to get the url when the page changes, using CustomTabsClient?

不幸的是你不能。 Chromium 错误跟踪器上还有一个 Unresolved 问题:

您现在唯一能做的就是知道选项卡何时开始或完成加载页面，但您无法检索 URL:

mClient.newSession(new CustomTabsCallback(){
    @Override
    public void onNavigationEvent(int navigationEvent, Bundle extras) {
        Log.w(TAG, "onNavigationEvent: Code = " + navigationEvent);

        switch (navigationEvent) {
            case NAVIGATION_STARTED:
                // Sent when the tab has started loading a page.
                break;
            case NAVIGATION_FINISHED:
                // Sent when the tab has finished loading a page.
                break;
            case NAVIGATION_FAILED:
                // Sent when the tab couldn't finish loading due to a failure.
                break;
            case NAVIGATION_ABORTED:
                // Sent when loading was aborted by a user action before it finishes like clicking on a link
                // or refreshing the page.
                break;
        }
    }
});
