You can easily hold some boolean variable for that case:
private boolean run = true;
then gather all the Buttons onClickListeners in one click listener, like the main one of the class, and upon anyclick make that variable run=false, So, check that before set the progress:
if(run){
pg_loading.setProgress(progressStatus);
}else{
//stop, finish, do whatever you want
}
in onClick listener:
public void onClick(View v) {
// TODO Auto-generated method stub
run = false;
Intent i;
switch (v.getId()) {
.
.
.
}
UPDATE:
make the thread as the following:
new Thread(new Runnable() {
public void run() {
while (progressStatus < 100) {
progressStatus += 1;
// Update the progress bar and display the
// current value in the text view
handler.post(new Runnable() {
public void run() {
if(run){
pg_loading.setProgress(progressStatus);
pg_loading.setProgressDrawable(getResources()
.getDrawable(R.drawable.progress));
}
}
});
try {
// Sleep for 200 milliseconds.
// Just to display the progress slowly
Thread.sleep(62);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
UPDATE 2:
your onPostExcute in the AsyncTask must be:
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
if (pDialog.isShowing())
pDialog.dismiss();
try {
countDownTimer.cancel();
pg_loading.setProgress(0);
progressStatus = 0;
new Thread(new Runnable() {
public void run() {
while (progressStatus < 100) {
progressStatus += 1;
// Update the progress bar and display the
// current value in the text view
handler.post(new Runnable() {
public void run() {
pg_loading.setProgress(progressStatus);
pg_loading
.setProgressDrawable(getResources()
.getDrawable(
R.drawable.progress));
}
});
I am writing a code in which I need to move all file and folders to the sdcard. I used Async task for this purpose. During this activity I am showing a progressbar with percentage on my screen instead of just showing me the "Loading..." popup. But it does not meet my requirement.
public class syncMgr extends AsyncTask<String, Long, String> {
public LoginActivity activity;
public Context context;
syncMgr(LoginActivity activity1,Context c)
{
activity = activity1;
context=c;
}
//public ProgressDialog progress;
protected void onPreExecute() {
super.onPreExecute();
activity.progress = ProgressDialog.show(context,"","Files Downloading, Please Wait...",true);
}
#Override
protected String doInBackground(String... arg0) {
// TODO Auto-generated method stub
copyFilesToSdCard();
return null;
}
private void copyFilesToSdCard() {
copyFileOrDir("");
}
private void copyFileOrDir(String path) {
AssetManager assetManager = activity.getAssets();
String assets[] = null;
try {
Log.i("tag", "copyFileOrDir() " + path);
assets = assetManager.list(path);
if (assets.length == 0) {
copyFile(path);
} else {
String fullPath = TARGET_BASE_PATH + path;
Log.i("tag", "path=" + fullPath);
File dir = new File(fullPath);
if (!dir.exists() && !path.startsWith("images")
&& !path.startsWith("sounds")
&& !path.startsWith("webkit"))
if (!dir.mkdirs())
Log.i("tag", "could not create dir " + fullPath);
for (int i = 0; i < assets.length; ++i) {
publishProgress((int) ((i / (float) 658) * 100));
String p;
if (path.equals(""))
p = "";
else
p = path + "/";
if (!path.startsWith("images")
&& !path.startsWith("sounds")
&& !path.startsWith("webkit"))
copyFileOrDir(p + assets[i]);
}
}
} catch (IOException ex) {
Log.e("tag", "I/O Exception", ex);
}
}
private void publishProgress(int i) {
// TODO Auto-generated method stub
activity.progress.setProgress(i);
}
#Override

Here is my Activity Class Code...
ProgressDialog progress;
public static final int progress_bar_type = 0;
/**

* */
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case progress_bar_type: // we set this to 0
progress = new ProgressDialog(this);
progress.setMessage("Downloading file. Please wait...");
progress.setIndeterminate(false);
progress.setMax(100);
progress.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progress.setCancelable(true);
progress.show();
return progress;
default:
return null;
}
}
Have you tried putting the asyncTask initiation code into a worker thread like this?
// set progressBar .VISIBLE first
// then...
new Thread(new Runnable() {
public void run() {
// webview initiation code
}
}).start();
I turn on progressBar visibility beforehand and not in onPreExecute().
Here is how it solved my own problem & here are the docs.

you have to implement SeekBar.OnSeekBarChangeListener to your class, then set the listener like this songProgressBar.setOnSeekBarChangeListener(this); and than implement these methods:
/*/
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromTouch)
{
}
/**
* When user starts moving the progress handler
* */
#Override

Here is a link of a fully working Media Player Example with seekbar touch listener and song progress update:
http://www.androidhive.info/2012/03/android-building-audio-player-tutorial/
Regarding the tutorial the only thing that will not work is retrieving and filtering the song from the given file path. Somehow I couldn't get it to work. But I found another solution which was to write your own FileFilter. But in your case you are using a URL so that doesn't matter.
I need to change the content of progress dialog when sync activity is running it shows "synchronizing data"
when it has completed it goes for another background activity and still shows the same text what I want is to change the text when it goes to other background task?
protected void onPreExecute() {
mDialog = ProgressDialog.show(viewContext, "", "Synchronizing Data",
true);
};
/*
* (non-Javadoc)
*
* #see android.os.AsyncTask#doInBackground(Params[])
*/
#Override
protected Boolean doInBackground(Void... arg0) {
if (type.contains("ferry")) {
return SynchronizeRepositoryFerry(false);
} else {
boolean value = SynchronizeRepositories(false, initialSync);
mDialog.setTitle("Loading Images");//FROM HERE I WANT TO CHANGE DIALOG
com.jumbybay.businessobjects.User user = new com.jumbybay.businessobjects.User();
DatabaseHelper dbHelper = new DatabaseHelper(viewContext);
IUserRepository repository = dbHelper.getUserRepository();
List<com.jumbybay.businessobjects.User> imageList;
try {
int id;
String url = "http://i.zdnet.com/blogs/3-29-androids.jpg";
imageList = repository.Retrieve();
for (int i = 0; i < imageList.size(); i++) {
user = imageList.get(i);
// url = user.getPicture();
id = user.getId();
fetchImage fetch = new fetchImage();
fetch.savesd(id, url);
}
} catch (SQLException e) {
// TODO Auto-generated catch block// url = user.getPicture();
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return value;
}
}
protected void onProgressUpdate(Integer... progress) {
mDialog.setTitle("lOADING IMAGES...");
}
/*
* (non-Javadoc)
*
* #see android.os.AsyncTask#onPostExecute(java.lang.Object)
*/
#Override
protected void onPostExecute(Boolean result) {
this.syncComplete = result;
mDialog.dismiss();
Intent intent = new Intent();
intent.setClass(viewContext, classType);
viewContext.startActivity(intent);
}
have you tried using it like this
mDialog.setTitle("Loading Images");
mDialog.show();
I am downloading a file from dropbox which is taking a few seconds. I want to add a ProgressDialog for the download but I don't know how to do that.
public class DownloadFile extends AsyncTask<Void, Long, Boolean> {
DownloadFile(Context context ,DropboxAPI<?> mApi ,String dropboxpath,String sdpath,int pos,int s,ArrayList<String> folder) throws DropboxException {
FileOutputStream mFos;
File file=new File(sdpath);
String path = dropboxpath;
try{
mFos = new FileOutputStream(file);
mApi.getFile(path, null, mFos, null);
}catch (Exception e) {
// TODO: handle exception
}
}
#Override
protected Boolean doInBackground(Void... params) {
// TODO Auto-generated method stub
return null;
}
}
Do it this way:
public final class DownloadFile extends AsyncTask<Void, Long, Boolean> {
private Context context;
private ProgressDialog progressDialog;
public DownloadFile (Context context) {
this.context = context;
}
/*
* #see android.os.AsyncTask#onPreExecute()
*/
#Override
protected void onPreExecute() {
try {
progressDialog = ProgressDialog.show(context, "", "message", true);
} catch (final Throwable th) {
//TODO
}
}
/*
* #see android.os.AsyncTask#doInBackground(Params[])
*/
#Override
protected Boolean doInBackground(Void... arg0) {
//do something
}
#Override
protected void onProgressUpdate(String... progress) {
//do something
super.onProgressUpdate(progress);
}
/*
* #see android.os.AsyncTask#onPostExecute(java.lang.Object)
*/
#Override
protected void onPostExecute(Boolean result) {
progressDialog.dismiss();
} }
Use this simple code #sachin
public class DownloadFile extends AsyncTask<Void, Void, Void> {
Home home;
ProgressDialog dialog = null;
public DownloadFile(Home home) {
// TODO Auto-generated constructor stub
this.home = home;
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
//Call hare method for download
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
dialog.dismiss();
}
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
dialog = ProgressDialog.show(home, "Downloading......", "", true);
}
}
This article can be useful for you:

Where inside the run() method of your thread you can invoke a function like this:
public boolean download(String url, String path, String fileName, Handler progressHandler) {
try {
URL sourceUrl = new URL(formatUrl(url));
if (fileName == null || fileName.length() <= 0) {
fileName = sourceUrl.getFile();
}
if (fileName == null || fileName.length() <= 0) {
throw new Exception("EMPTY_FILENAME_NOT_ALLOWED");
}
File targetPath = new File(path);
targetPath.mkdirs();
if (!targetPath.exists()) {
throw new Exception("MISSING_TARGET_PATH");
}
File file = new File(targetPath, fileName);
URLConnection ucon = sourceUrl.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(100);
int current = 0;
int totalSize = ucon.getContentLength();
while ((current = bis.read()) != -1) {
baf.append((byte) current);
// BEGIN - Handler feedback
if (progressHandler != null && (baf.length() % 100) == 0) {
Message msg = progressHandler.obtainMessage();
Bundle b = new Bundle();
if (totalSize > 0) {
b.putInt("total", totalSize);
b.putInt("step", baf.length());
b.putBoolean("working", true);
}
msg.setData(b);
progressHandler.handleMessage(msg);
}
// END
}
FileOutputStream fos = new FileOutputStream(file);
fos.write(baf.toByteArray());
fos.close();
// BEGIN - Handler feedback
if (progressHandler != null) {
Message msg = progressHandler.obtainMessage();
Bundle b = new Bundle();
if (totalSize > 0) {
b.putInt("total", 0);
b.putInt("step", 0);
b.putBoolean("working", false);
}
msg.setData(b);
progressHandler.handleMessage(msg);
}
// END
return file.exists();
}
Doing this way, you have a more accurate feedback about real progress of you download (byte per byte).
See there are actually 4 methods of AsyncTask:
onPreExecute() - you can do some pre execution task here.
doInBackground() - you can perform some background work here.
onPostExecute() - you can perform post execution task here. Means like displaying data in ListView, update TextView, etc.
onProgressUpdate() - To update UI while background operation is going on.
So in your case, you can show progress dialog or progress bar inside onPreExecute() method of AsyncTask and dismiss(() the same inside onPostExecute().
