Flutter:如何在Web视图中启用手势? [英] Flutter: how to enable gestures in a web view?

问题描述

我想放大或缩小以在Flutter中放大我的Web视图页面. 我在网上做了一些研究，然后在某个地方找到了它:

I would like to pinch in and out to zoom in my web view page in Flutter. I did some researches online and I found this somewhere:

尽管捏合和缩放内置于WebView(Android)和UIWebView(iOS)，但它们需要打开". 在Android中，该插件需要调用以下内容:

"Although pinch and zoom are built-in to WebView (Android) and UIWebView (iOS), they need to be "switched-on". In Android, the plugin needs to call the following:

this.webView.getSettings().setBuiltInZoomControls(true);
this.webView.getSettings().setSupportZoom(true); to allow pinch/zoom.

在iOS中，该插件需要调用以下内容:

In iOS, the plugin needs to call the following:

self.webview.scalesPageToFit = YES; to allow pinch/zoom."

问题是我不知道将这段代码放在哪里/我不知道如何使用它. 有人可以帮我吗?

The problem is that I don't know where to put this code/I don't know how to use it. Can anyone help me, please?

推荐答案

在webview声明后放置zoom方法，请参考以下代码

Put the zoom method after webview declaration,Please refer below code

public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.show_web_view);

        webView = (WebView) findViewById(R.id.webView1);
        WebSettings webSettings = webView.getSettings();
        webSettings.setBuiltInZoomControls(true);
        webSettings.setSupportZoom(true);
}
