提问by zaiff
I have an html file in assets, aaa.html. I want to read the contents of html file and replace it from another string.
我在资产中有一个 html 文件，aaa.html。我想读取 html 文件的内容并从另一个字符串替换它。
Is this way is right or is there any other option.
这种方式是对的还是有其他选择。
my code:
我的代码：
File f = new File("file:///android_asset/aaa.html");
FileReader fr = new FileReader(f);
BufferedReader br = new BufferedReader(fr);
But its giving file not found, where as loading in web view loads the file.
但是找不到它的给定文件，在 web 视图中加载时加载文件。

InputStream is = getAssets().open("aaa.html");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
String str = new String(buffer);
str = str.replace("old string", "new string");

If you want to load file in webview then use this
如果你想在 webview 中加载文件然后使用这个
mWebView.loadUrl("file:///android_asset/myfile.html");
you want to replace content inside Html file tags so the solution class code is here..
您想替换 Html 文件标签内的内容，因此解决方案类代码在这里..
public class CardDetail {
public static String newHtmlString = "";
// private Context context;
@SuppressWarnings("rawtypes")
public String getNewHtmlString(String htmlString, HashMap hm) {
try {
StringTokenizer st = new StringTokenizer(htmlString, "##");
CardDetail.newHtmlString = "";
while (st.hasMoreTokens()) {
String token = st.nextToken();
CardDetail.newHtmlString += token;
if (st.hasMoreTokens()) {
String token2 = st.nextToken();
if (token2.equals("NAME") || token2.equals("POSITION") || token2.equals("COMPANY") || token2.equals("PHOTOURL"))
CardDetail.newHtmlString += hm.get(token2);
if (token2.equals("SKYPE_CONTAINER1")
|| token2.equals("TWITTER_CONTAINER1")
|| token2.equals("PHONENUMBER_CONTAINER1")
|| token2.equals("EMAIL_CONTAINER1")
|| token2.equals("ADDRESS_CONTAINER1")) {
String replaceString = st.nextToken();
String tokenMiddle = (String) hm.get(st.nextToken());
if (!tokenMiddle.equals("")) {
replaceString += tokenMiddle;
CardDetail.newHtmlString += replaceString + st.nextToken();
st.nextElement();
} else {
st.nextElement();
st.nextElement();
}
}
}
}
// Log.i("convertedHTMLString", newHtmlString);
return CardDetail.newHtmlString;
// htmlString = "<img src='" + hm.get("PHOTOURL") + "' width=80 height=80>";
// return htmlString;
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return null;
}

public HashMap<?, ?> getProfileHashMap(JSONObject jsonObject) {
@SuppressWarnings("rawtypes")
HashMap hm = new HashMap();
jsonObject = (new JSONConverterClass()).convertJsonObjectToCardDetail(jsonObject);
try {
hm.put("EMAIL", jsonObject.getString("email"));
hm.put("NAME", jsonObject.getString("firstname") + " " + jsonObject.getString("lastname"));
hm.put("COMPANY", jsonObject.getString("company_name"));
hm.put("POSITION", jsonObject.getString("position"));

hm.put("TWITTER", jsonObject.getString("twitter_username"));
hm.put("ADDRESS", jsonObject.getString("generic_location"));
} catch (Exception e) {
e.printStackTrace();
}
return hm;
}

convertJsonObjectToCardDetail this class just replace string with values from Json hope this solves your problem ....
convertJsonObjectToCardDetail 这个类只是用来自 Json 的值替换字符串，希望这能解决你的问题......
