我有一个包含一个单一的web视图显示不同的HTML内容基于一个通用的活动。

每个HTML内容meta标签是这样的。

 ＆LT; META NAME =视口CONTENT =WIDTH =设备的宽度，高度=设备的高度，最小规模为0.4，最大规模= 3，初始规模= 0.5＆GT; 

和编程的WebView配置，以适应这些$ C $屏幕内容CS。

 的WebView web视图=（的WebView）findViewById（R.id.webview1）;        webView.getSettings（）setJavaScriptEnabled（真）。        。webView.getSettings（）setLoadWithOverviewMode（真）;        。webView.getSettings（）setUseWideViewPort（真）;        webView.setScrollBarStyle（WebView.SCROLLBARS_OUTSIDE_OVERLAY）;        webView.setScrollbarFadingEnabled（真）;        。webView.getSettings（）setBuiltInZoomControls（真）;        。webView.getSettings（）setLoadsImagesAutomatically（真）;        webView.getSettings（）setLightTouchEnabled（真）。        webView.getSettings（）setDomStorageEnabled（真）。        webView.setBackgroundColor（0）; 

不幸的是既不元code和的WebView配置不会在屏幕上不适合的内容;但双攻适合的内容非常好。所以我不知道我可以可模拟双编程敲击的WebView？

创建一个这样的类并调用simulateDoubleTap（）基准值确定方法。希望这将帮助，和你的WebView应该是这个类的一个实例。

I have a generic activity that contains a single webview to show different html based content.

Every html content has meta tag like this.

<meta name="viewport" content="width=device-width,height=device-height, minimum-scale=0.4, maximum-scale=3,initial-scale=0.5"> 

And WebView programmatically configured to fit content in screen with these codes.

WebView webView = (WebView) findViewById(R.id.webview1);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setLoadWithOverviewMode(true);        
        webView.getSettings().setUseWideViewPort(true);     
        webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
        webView.setScrollbarFadingEnabled(true);
        webView.getSettings().setBuiltInZoomControls(true);    
        webView.getSettings().setLoadsImagesAutomatically(true);
        webView.getSettings().setLightTouchEnabled(true);
        webView.getSettings().setDomStorageEnabled(true);

        webView.setBackgroundColor(0);

Unfortunately neither meta code nor webview configurations doesn't fit content in screen; but double tapping fits content excellent. So i wonder can i simulate double tapping on webview programmatically?

Create a class like this and call simulateDoubleTap() methord. Hope this will help, and your webview should be an instance of this class.
