How to generate CSV file from Android Studio Table Layout

I'm developing an android app that stores user input in the SQLite database. and displays it in TableLayout in android studio. Now I want to generate a CSV file from the contents of that Table Layout.
I need a button to generate the CSV file. Thanks in advance.
I'm new to StackOverflow and coding. So forgive me If my question wasn't right.
I really need this code to complete my project. Thanks in Advance.

Here is a sample complete project for reading data from Rss-provider insert to database and show on listview then in next activity create a csv file.
In the first activity wait to load data form Rss-provider after showing in list view data stored in DB, then click button to go to next activity for creating Csv list
For creating csv all columns should be separated with comma (,).

How to put a progress bar with thread safety in android while hitting a server and waiting for response?

I have an application where I am recording audio in an activity. User has a start recording and stop recording button to do that. Once user clicks the stop recording button, it sends the recorded mp3 file to server (encoded string) and server process it and a response is received. I want to do the following tasks:
Since this process is long, I want to do this in a separate thread(preferably).
The process of sending and receiving response is to be shown using progress bar.
User should be able to navigate to other screens while he is waiting(i.e. current activity may be destroyed)
I tried using Toast messages before and after the function where I send mp3 to server. But there is no sync, sometimes msg comes early, sometime it's late. That's why a proper progress bar is required.How to do this? Can AsyncTask be used with what I want to achieve in (3). or should I use some other form of multithreading. Please help.Below is the activity

You can use an IntentService to upload your content to the server. By default, it runs on a seperate thread and is not activity bound. Then use a broadcast receiver to communicate the result back to any activity. You can find an example here.
For the progress bar, you can create a notification and show the progress bar there, this will not block your application's UI.

For hitting the server at you should use AsyncTask or Runnable thread, without disturb the main tread
for custome progress dialog use the following code
xml file.
<?xml version="1.0" encoding="utf-8"?>

Onclicklistener only working once

My onclicklistener for my "LoginBtn". However that code inside that block only runs once and then doesn't run ever again. Please help me, I've tried everything. I know so because I have ran the log and it only logs out the value once and then never again.

Download file in Android using ProgressbarDialog

I am trying to develop a simple application for download using DownloadManager but I need to do some changes, I want to download using ProgressbarDialog so how to do.
class DownloadReceiver
if(downloader == null) return;
long completeId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, 0);
if(completeId == downloadTaskId){
Query query = new Query();
query.setFilterById(downloadTaskId);
Cursor cur = downloader.query(query);
if (cur.moveToFirst()) {
int columnIndex = cur.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == cur.getInt(columnIndex)) {
//Download the task has been completed, remove
new VersionPersistent(context).clear();
String uriString = cur.getString(cur.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
File apkFile = new File(Uri.parse(uriString).getPath());
Intent installIntent = new Intent();
installIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
installIntent.setAction(Intent.ACTION_VIEW);
installIntent.setDataAndType(Uri.fromFile(apkFile),"application/vnd.android.package-archive");
context.startActivity(installIntent);
} else {
Toast.makeText(context, R.string.download_failure, Toast.LENGTH_SHORT).show();
}
}
cur.close();
and also
download and install
if ( latestVersion == null || !isNetworkActive() ) return;
downloader = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
Query query = new Query();
query.setFilterById(downloadTaskId);
Cursor cur = downloader.query(query);
// Download tasks already exists
if(cur.moveToNext()) return;
DownloadManager.Request task = new DownloadManager.Request(Uri.parse(latestVersion.targetUrl));
String apkName = extractName(latestVersion.targetUrl);
String title = String.format("%s - v%s", apkName,latestVersion.name);
task.setTitle(title);
task.setDescription(latestVersion.feature);
task.setVisibleInDownloadsUi(true);
task.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE | DownloadManager.Request.NETWORK_WIFI);
task.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, apkName);
downloadTaskId = downloader.enqueue(task);
Thanks :)

USE this class to show progress bar , this will give you an idea for downloading an image.
DownloadImageTask.java
private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
/** Reference to the view which should receive the image */
private final WeakReference imageRef;
public DownloadImageTask(ImageView imageView) {
imageRef = new WeakReference(imageView);
}
#Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog = ProgressDialog.show(DownloadImageActivity.this, "Wait", "Downloading...");
}
#Override
protected Bitmap doInBackground(String... params) {
InputStream input = null;
try {
URL url = new URL(params[0]);
// We open the connection
URLConnection conection = url.openConnection();
conection.connect();
input = new BufferedInputStream(url.openStream(), 8192);
// we convert the inputStream into bitmap
bitmap = BitmapFactory.decodeStream(input);
input.close();
} catch (Exception e) {
Log.e("Error: ", e.getMessage());
}
return bitmap;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(Bitmap bitmap) {
progressDialog.dismiss();
if (isCancelled()) {
bitmap = null;
}
if (imageRef != null) {
ImageView imageView = imageRef.get();
if (imageView != null && bitmap != null) {
imageView.setImageBitmap(bitmap);
} else
Toast.makeText(DownloadImageActivity.this, "Error while downloading the image!", Toast.LENGTH_LONG).show();
}
}
}
give permission in AndroidMenifest.xml
<uses-permission android:name="android.permission.INTERNET"/>

you want using progressDialog, does that mean you don't need to download in the background ?
My solution is:
using AsyncTask
init the profressDialog before you call task.execute()
then show the dialog in onPreExecute
download file doInBackfround
update progess in onProgressUpdate
and dosomething you want when download complete in onPostExecute
you can learn AsyncTask and HttpURLConnection and IO Stream

You should use DownloadManager's
DownloadManager.query(DownloadManager.Query)
This gives you a Cursor to browse the columns COLUMN_TOTAL_SIZE_BYTES (Total size of the download in bytes) and COLUMN_BYTES_DOWNLOADED_SO_FAR (Number of bytes download so far).
With this information, you'll have the details to update the ProgressBarDialog.

Use Asynctask for this. Try this.
private class DownloadFileTask extends AsyncTask<String, Void, String> {
ProgressDialog pd;
#Override
protected String doInBackground(String... params) {
// Your File Download Code here
}
#Override
protected void onPostExecute(String result) {
pd.dismiss();
}
#Override
protected void onPreExecute() {
pd = new ProgressDialog(yourActivity.this);
pd.setMessage("Please Wait...");
pd.show();
}
#Override
protected void onProgressUpdate(Void... values) {}
}
}

This is my working sample code. I use SeekBar instead of ProgressBar. Hope this help

Do this way Hope this works for you
EditText editText = (EditText)findViewById(R.id.editText);
String userName = "usernamejay";
String message = "Hi This is Jay. How are you?";
String finalStr = "<b>"+userName+":</b> "+message+"";
editText.setText(Html.fromHtml(finalStr));

On Android you can use HTML to style the text inside a TextView, see here http://daniel-codes.blogspot.pt/2011/04/html-in-textviews.html

You could also use a spannable string, may be you could look at a portion of the code in this answer.
A code extract from the link
final SpannableString out0 = new SpannableString(source[position]);
StyleSpan boldSpan = new StyleSpan(Typeface.BOLD);
out0.setSpan(boldSpan, 6, 17, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
holder.tv.setText(out0);
P.S: but please read the solution in the link before you start applying things in your code.
