如果我使用路径获取 html 内容，我将面临应用程序已停止的错误。但是如果我在代码行中一个一个地编写 HTML 内容，如“.......”，那么程序就会运行。哪里有问题？
安卓文件；
private WebView webView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webcontent);
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
String content = null;
try {
content = Files.toString(new File("C:\\Users\\-SurrealBlack-\\Desktop\\b.html"), Charsets.UTF_8);
} catch (IOException e) {
e.printStackTrace();
}
webView.loadData(content, "text/html", "UTF-8");
}

最佳答案
我喜欢这个，这是我的“食谱”:
将您的 htm 文件放入设备(模拟或物理)的 Assets 文件夹中
然后像这样访问它:
pgHelp = "file:///android_asset/help/help-" + lang + ".htm";
web = (WebView) v.findViewById(R.id.htmlDisplay);
web.loadUrl(pgHelp);
我的文件名为 help-xy.htm，其中 xy 是语言环境(en、de、fr、it、es)，
存储在 lang 变量中。
如您所见，它们存储在 Assets 路径中名为“help”的文件夹下
