Save HTML and read in Android
Question
I have created a function to generate receipt to save as text in the file. but when I try to read that file, it shows me with HTML tags. but when I open the text file from a phone using WPS office that doesn't show me HTML tags this is when I open text file in phone:
this when I read file:
and this my code-:
File file = new File(Environment.getExternalStorageDirectory().toString());
file.mkdir();
if (file != null) {
Log.d("created", "notnull");
} else {
Log.d("created", "null");
}
File gpxfile = new File(file, "samples.txt");
FileWriter writer = null;
try {
Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(gpxfile), Charset.forName("ASCII")));
//writer = new FileWriter(gpxfile);
//writer.write(billHTML());
out.write(billHTML());
//Log.d("writer", "" + billHTML());
//writer.close();
out.close();
**here i read file**
BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream(gpxfile), "ASCII"));
String sData;
while ((sData = in.readLine()) != null) {
System.out.println(sData);
}
Log.d("files", "" + in);
} catch (IOException e) {
e.printStackTrace();
}
this is genreate bill function.
public String billHTML() {
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy HH:mm");
Calendar c = Calendar.getInstance();
StringBuilder sb = new StringBuilder();
sb.append("<html>"
+ "<body>");
sb.append("<br>");
sb.append("<h1><br><center> Texto mi marca </<center></h1>");
sb.append("<h2><center> Texto mi marca </<center></h2>");
sb.append("<br>");
sb.append("<br>");
sb.append("<center>Fecha:  " + sdf.format(c.getTime()));
sb.append("<br>");
sb.append("<center>Factura:  " + sdf.format(c.getTime()));
sb.append("<br>");
sb.append("<center>Cllente al contado");
sb.append("<br>");
sb.append("<br>");
sb.append("<h2><center>-------------------------------------------</h2>");
sb.append("<br>");
sb.append("<br>");
sb.append("<br>");
sb.append("<br>");
sb.append("<br>");
sb.append("<table width=550>" +
" <tr>" +
" <th width='50%' align='left'> Description</th>" +
" <th width='10%' align='left'>Units</th>" +
" <th width='10%' align='right'>Price</th>" +
" </tr>");
for (int i = 0; i < Util.itemArrayList.size(); i++) {
sb.append("<tr>"
+ "<td>").append(Util.itemArrayList.get(i).description)
.append("</td>"
+ "<td align='left'>")
.append(Util.itemArrayList.get(i).units)
.append("</td>"
+ "<td align='right'>")
.append(Util.itemArrayList.get(i).price + "€")
.append("</td>"
+ "</tr>");
oldpay = Util.itemArrayList.get(i).price;
totalprice = totalprice + oldpay;
}
float basevalue = (float) (totalprice / 1.21);
float ivaValue = totalprice - basevalue;
sb.append("<tr>"
+ "<td>").append("-----------------------")
.append("</td>"
+ "<td align='right'>");
sb.append("<tr>"
+ "<td>")
.append("(Total)Base imponible")
.append("</td>"
+ "<td align='right'>")
.append("</td> "
+ "<td align='right'>")
.append(decimalFormat.format(basevalue) + "€")
.append("</td>"
+ "</tr>");
sb.append("<tr>"
+ "<td>")
.append("IVA (+21%)")
.append("</td>"
+ "<td align='right'>")
.append("</td> "
+ "<td align='right'>")
.append(decimalFormat.format(ivaValue) + "€")
.append("</td>"
+ "</tr>");
sb.append("<tr>" +
"<td>").append("==============================================").append("</td>" +
"<td>==========</td>" +
"<td>===========</td>");
sb.append("<tr>"
+ "<td>").
append("<b>Total </b>")
.append("</td>"
+ "<td align='right'>")
.append("</td> "
+ "<td align='right'>")
.append(decimalFormat.format(totalprice) + "€")
.append("</td>"
+ "</tr>");
sb.append("</table>");
System.out.print(sb.toString());
return sb.toString();
}

If you are using html markup to generate the receipt you probably should name the file something like sample.html instead of sample.txt this way in your computer will be opened by a internet browser instead of the notepad.
Probably WPS Office is smart enough to detect the html tags and display the file with the correct formatting.
