如何使用Firebase动态更改Webview的URL? [英] How to change an URL for webview dynamically using firebase?

问题描述

我有一个加载URL(www.google.com)的网络视图.如何更改Webview以从外部加载其他网址，例如在Firebase中编写网址?是否可以?我希望有一个外部更改URL的选项，而不必在活动中更改URL即可重新安装应用程序.

I have an webview which load an URL(www.google.com). How can I change the webview to load an different url externally like by writing the url in firebase? Is it possible? I want an option to change the url externally without having to change the url in the activity an reinstall the app.

推荐答案

那只是侦听存储在Firebase中的url路径，例如

That simply just listen on url path that store in firebase like

private DatabaseReference mUrlReference = FirebaseDatabase.getInstance().getReference().child("url")
ValueEventListener urlListener = new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        String url = dataSnapshot.getValue(String.class);
        // Web load here
        webView.loadUrl(url);
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {
        // Getting Url failed, log a message
        Log.w(TAG, "loadUrl:onCancelled", databaseError.toException());
        // ...
    }
};
mUrlReference.addValueEventListener(urlListener);
