Question

我在webview内有一个Scrollview。点击webview时我需要进行缩放控制，但显然当父布局为scrollview时它不起作用。解决办法是什么？有没有办法在这种情况下进行变焦控制？

这是我的xml代码：

使用，

 webView.getSettings().setBuiltInZoomControls(true);
 webView.getSettings().setDisplayZoomControls(false);

和

检查您是否没有 ScrollView包装您的Webview 。

就我而言，这就是问题所在。似乎ScrollView妨碍了捏合手势。

要修复它，只需将您的Webview放在ScrollView外面。

在scrollview中启用webview缩放控件
