推荐答案

使用 webSettings 类

webview.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);

请注意，虽然 webSettings 是可用，因为API级别1，<一个href="http://developer.android.com/reference/android/webkit/WebSettings.ZoomDensity.html">WebSettings.ZoomDensity可因为API级别7.非常适用于所有的设备分辨率。

Notice that although webSettings is available since API Level 1, WebSettings.ZoomDensity is available since API Level 7. Works well for all device resolutions.

此外，为了在web视图允许缩放，添加以下code：

Also, in order to enable zoom on the webView, add the following code:

webView.getSettings().setBuiltInZoomControls(true);
