android - 如何从 Android 中的 Chrome 选项卡获取回调，例如 web View 提供了 shouldOverrideUrlLoading、onLoadResource、onPageFinished

Question

我想在我的项目中用 Chrome 自定义标签替换 WebView 。为了替换 webview，我需要像 android web view 提供的那样在 Chrome 选项卡中进行回调。那么是否有任何回调可用或不可用，如果可用，那么它们是什么？请帮我。提前致谢。

您只能在 chrome 自定义标签中提供以下回调:

/**
* Sent when the tab has started loading a page.
*/
public static final int NAVIGATION_STARTED = 1;

/**
* Sent when the tab has finished loading a page.
*/
public static final int NAVIGATION_FINISHED = 2;

/**
* Sent when the tab couldn't finish loading due to a failure.
*/
public static final int NAVIGATION_FAILED = 3;

/**
* Sent when loading was aborted by a user action before it finishes like clicking on a link
* or refreshing the page.
*/
public static final int NAVIGATION_ABORTED = 4;

/**
* Sent when the tab becomes visible.
*/
public static final int TAB_SHOWN = 5;

/**
* Sent when the tab becomes hidden.
*/
public static final int TAB_HIDDEN = 6;

要附加回调，请像往常一样绑定(bind)到自定义选项卡服务，并在调用 newSession() 时传递回调。
