webview最全面详解（一）了解官方文档，Android攒了一个月的面试题及解答_setcontentview(webview);

To provide a WebView in your own Activity, include a in your layout, or set the entire Activity window as a WebView during onCreate():

请参阅意图获取更多信息。

要在你的activity中支持webview，需要在layout中添加标签，或者在 onCreate()方法中将整个activity窗口设置为一个webview。

WebView webview = new WebView(this);

setContentView(webview);

Then load the desired web page:

然后加载所需网页

// Simplest usage: note that an exception will NOT be thrown

// if there is an error loading this page (see below).

// 最简单的应用：注意在这种情况下，如果在加载的页面出现错

webview.loadUrl(“https://example.com/”);

// OR, you can also load from an HTML string:

//而或，你也可以加载HTML字符串

String summary = “You scored 192 points.”;

webview.loadData(summary, “text/html”, null);

// … although note that there are restrictions on what this HTML can do.

// See loadData(String, String, String) and loadDataWithBaseURL(String, String, String, String, String) for more info.

// Also see loadData(String, String, String) for information on encoding special characters.

当然，要注意的是加载HTML是有限制的

请查阅loadData(String, String, String)和loadDataWithBaseURL(String, String, String, String, String)文档获取更多信息。

有关编码特殊字符的信息，另请参阅loadData（String，String，String）。
