You have to give the path of that file like this. 你必须像这样给出该文件的路径。
String extStorageDirectory = Environment.getExternalStorageDirectory()
.toString() + "/folder_name";
File directory = new File(extStorageDirectory);
File fileInDirectory = new File(directory,file_name.html);
//Read text from file
StringBuilder html_text = new StringBuilder();
try {
BufferedReader br = new BufferedReader(new FileReader(fileInDirectory));
String line;
while ((line = br.readLine()) != null) {
html_text.append(line);
html_text.append('\n');
}
}
catch (IOException e) {
//You'll need to add proper error handling here
}
then use this html code for edit 然后使用此HTML代码进行编辑
String message ="<font color='white'>"+"<u>"+"text in white"+ "<br>" +"<font color='cyan'>"+"<font size='2'>"+" text in blue color "+"</font>";
webview.loadData(message, "text/html", "utf8");

htmlDetail = dbValues.getContent(3);
tvDescription3.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
String finalHtml = "<html><head>"
+ "<style type=\"text/css\">li{color: #00f} span {color: #000}"
+ "</style></head>"
+ "<body>"
+ htmlDetail
+ "</body></html>";
tvDescription3.loadData(finalHtml, "text/html; charset=UTF-8", null);

put your file path as 把你的文件路径
String htmlPath = "file:///mnt/sdcard/test/11.html";
String baseUrl = "file:///mnt/sdcard/test/";
webView.loadDataWithBaseURL(baseUrl, message, "text/html", "utf-8", null);
webView.loadUrl(htmlPath);

In order to change a WebView's background color there is a standard way: 为了更改WebView的背景颜色，有一种标准方式：
mWebView.setBackgroundColor(Color.Black);
In order to change a WebView's text font color there is no standard way: Either you change the font through the html code, or you do this: 为了更改WebView的文本字体颜色，没有标准方法：您可以通过html代码更改字体，或者执行以下操作：
htmlData="<font color='black'>" + htmlData + "</font>";
mWebView.loadDataWithBaseURL(null, htmlData, "text/html", "UTF-8", null);
