How to Display HTML Text in Android TextView?

I Have an HTML Text.
Sales Resources Drive to Collab Partner PresentationUS-CanadaLATAMEMEARAPJCDrive to Collab Program FAQsPlatform for Voice and Video Campaign
I would like to display this text in Android Text View. I have tried MyTagHandler to display, it is working fine while displaying, but the text formating is not good. If the bulleted text has 2 lines then the second line is coming from first, but i need space upto bullet. how can i handle this?

i guess like this...
TextView foo = (TextView)findViewById(R.id.foo);
foo.setText(Html.fromHtml("your html text"));

You can do that in 2 ways.
First you create a HTML Script for it.
Once you are done with it, then set that to textview as shown below.
(preferable for smaller text)
myTextView.setText(Html.fromHtml("Html Script"));
Create a html file and put it in res/raw.
Then use the follwoing code.
myTextView.setText(Html.fromHtml(getHtmlText()));
Now define getHtmlText() method as below:
private String getHtmlText(){
InputStream inputStream = getResources().openRawResource(R.raw.my_html_file);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
int i;
try {
i = inputStream.read();
while (i != -1)
{
byteArrayOutputStream.write(i);
i = inputStream.read();
}
inputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return byteArrayOutputStream.toString();
}

android separating a text file

I've been researching about how diablo 2 dynamically generates loot, and I thought it'd be fun to create a fun app that will randomly generate items using this system.
I currently have code which I believe should read the entire txt file, but it's not parsed.
It looks like:
private void itemGenerator() {
int ch;
StringBuffer strContent = new StringBuffer("");
InputStream fs = getResources().openRawResource(R.raw.treasureclass);
// read file until end and put into strContent
try {
while((ch = fs.read()) != -1){
strContent.append((char)ch);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
An example in the text file would look something like:
Treasure Class Item1 Item2 Item3
tc:armo3 Quilted_Armor Buckler Leather_Armor
tc:armo60a Embossed_Plate Sun_Spirit Fury_Visor
tc:armo60b Sacred_Rondache Mage_Plate Diadem
So what I'm thinking right now is putting each row into an array with StringTokenizer delimited by \n to get each row. Then somehow do it again with tab-delimited for each item in the array and put it into a 2D array?
I haven't coded it yet because I think there's a better way to implement this that I haven't been able to find, and was hoping for some helpful input on the matter.
For anyone actually interested in knowing how the item generation works, their wiki page, http://diablo2.diablowiki.net/Item_Generation_Tutorial, goes very in-depth!

I think you are facing problem in distinguishing between each lines that are read-out from file. In order to read the file line-by-line you should change your code as below:
InputStream fs = getResources().openRawResource(R.raw.treasureclass);
BufferedReader br = new BufferedReader(new InputStreamReader(fs));
String line = null;
while((line = br.readLine()) != null){
Log.i("line", line);
//split the content of 'line' and save them in your desired way
}

Why are foreign characters not read using inputStream?

I have a text file which contains data I need to preload into a SQLite database. I saved in in res/raw.
I read the whole file using readTxtFromRaw(), then I use the StringTokenizer class to process the file line by line.
However the String returned by readTxtFromRaw does not show foreign characters that are in the file. I need these as some of the text is Spanish or French. Am I missing something?
Code:
String fileCont = new String(readTxtFromRaw(R.raw.wordstext));
StringTokenizer myToken = new StringTokenizer(fileCont , "\t\n\r\f");
The readTxtFromRaw method is:
private String readTxtFromRaw(Integer rawResource) throws IOException
{
InputStream inputStream = mCtx.getResources().openRawResource(rawResource);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
int i = inputStream.read();
while (i != -1)
{
byteArrayOutputStream.write(i);
i = inputStream.read();
}
inputStream.close();
return byteArrayOutputStream.toString();
}
The file was created using Eclipse, and all characters appear fine in Eclipse.
Could this have something to do with Eclipse itself? I set a breakpoint and checked out myToken in the Watch window. I tried to manually replace the weird character for the correct one (for example í, or é), and it would not let me.

Have you checked the several encodings?
what's the encoding of your source file?
what's the encoding of your output stream?
the byteArrayOutputStream.toString() converts according to the platform's default character encoding. So I guess it will strip the foreign characters or convert them in a way that they are not displayed in your output.
Have you already tried to use byteArrayOutputStream.toString(String enc)? Try "UTF-8" or "iso-8859-1" or "UTF-16" for the encoding.

Android: Character encoding raw resource files

I'm in the process of translating one of my apps to Spanish, and I'm having a character encoding problem with a raw HTML file I'm sticking into a WebView. I have the spanish translation of the file in my raw-es folder, and I'm reading it in with the following function:
private CharSequence getHtmlText(Activity activity) {
BufferedReader in = null;
try {
in = new BufferedReader(new InputStreamReader(getResources().openRawResource(R.raw.help), "utf-8"));
String line;
StringBuilder buffer = new StringBuilder();
while ((line = in.readLine()) != null) buffer.append(line).append('\n');
return buffer;
} catch (IOException e) {
return "";
} finally {
closeStream(in);
}
}
But everywhere there is a spanish character in the file, there is a diamond with a question mark inside of it when I run the app, and look at the activity that displays the HTML. I'm using the following to load the text into the WebView:
mWebView.loadData(text, "text/html", "utf-8");
I originally created the file in Microsoft Word, so I'm sure there is some sort of character encoding issue going on, but I'm not really sure how to fix it, and a Google search isn't helping. Any ideas?

Don't use loadData. Use loadDataWithBaseURL instead. You would say:
mWebView.loadDataWithBaseURL( null, text, "text/html", "utf-8", null );

I had a similar issue with a French translation where diamond symbols with question marks were appearing in place of certain characters, including those which I had escaped. I got around it by opening file properties in Eclipse and changing the encoding to "ISO-8859-1". Don't know if this would work for Spanish though.

Android: How to read a txt file which contains Chinese characters?

i have a txt file which contains many chinese characters, and the txt file is in the directory res/raw/test.txt. I want to read the file but somehow i can't make the chinese characters display correctly. Here is my code:
try {
InputStream inputstream = getResources().openRawResource(R.raw.test);
BufferedReader bReader = new BufferedReader(
new InputStreamReader(inputstream,Charset.forName("UTF-8")));
String line = null;
while ((line= bReader.readLine())!= null) {
Log.i("lolo", line);
System.out.println("here is some chinese character 这是一些中文字");
}
} catch (IOException e) {
e.printStackTrace();
}
Both Log.i("lolo", line); and System.out.println("here is some chinese character 这是一些中文字") don't show characters correctly, i can not even see the chinese characters in the println() method.
What can i do to fix this problem? Can anybody help me?

In order to correctly handle non-ASCII characters such as UTF-8 multi-byte characters, it's important to understand how these characters are encoded and displayed.
Your console (output screen) may not support the display of non-ASCII characters. If that's the case, your UTF-8 characters will be displayed as garbage. Sometimes, you will be able to change the character encoding on the console. Sometimes not.
Even if the console correctly displayed UTF-8 characters, it's possible that your string does not correctly store the Chinese characters. You may think that it's correct because your editor displays them, but ensure that the character encoding of your editor also supports UTF-8.

I also was trying to figure out that. First you need to open the .txt file with the notepad and then click on File->Save as, there you will see a dropdown menu that says Enconding, so change it to UTF-8. After saving the file you should remove the .txt extension to the file and then add the file to the path res/raw and then you can refer to it from the code as R.raw.txtFileName.
That's all, i will put my code where I used the chinese characters and I could show them in the emulator.
If you have any other question, let me know because i am also developing something related with characters. Here is the code:
public List<String> getWords() {
List<String> contents = new ArrayList<String>();
try {
InputStream inputStream = getResources().openRawResource(R.raw.chardb);
BufferedReader input = new BufferedReader(new InputStreamReader(inputStream,Charset.forName("UTF-8")));
try {
String line = null;
while (( line = input.readLine()) != null){
contents.add(line);
}
}
finally {
input.close();
}
}
catch (IOException ex){
ex.printStackTrace();
}
return contents;
}
