Android :: Progress Bar Before Going To Next Activity?
Mar 30, 2009
My application involves doing some calculation on the first activity and sending the information to the second activity. So while the calculation is being done , I want to show a activity / progress / busy indicator on the first activity , before going to the second one. Is there any way of doing so, or an sample code that does the same. I was also looking out for the same by calling the calculation method after a delay so that the progress bar is shown first before the calculation is done , but this has also failed.

I have a service that downloads something from the Internet, it shows progress in notifications and in MyActivity (only when MyActivity is on foreground of course). How should the service post the progress to MyActivity? I know this could be done somehow with IBind but can I just simply do this in MyActivity:
MySevice.myActivity = this; startService(new Intent(....));
From MyService I can now call MyActivity's methods because I have a static reference to it in MySevice.myActivity, so I can call e.g. myActivity.sendProgress(63).

this is the current state/situation: I have an Activity which binds a Service which creates AsyncTasks which downloads various web resources. That works well, but of course the ProgressBar shows nothing. Previously i had an Activity which created an AsyncTask which downloaded some stuff. The AsyncTask got the View which holds the ProgressBar. So i could update the progress using onProgressUpdate and publishProgress. Obviously this doesn't work any longer because I have no reference to the ProgressBar.

On menu item click, I spawn a Service which, onCreate(), which is where I want to be able to update the progress bar. what am I missing?.............

I encounter a problem with a ProgressDialog in a PreferencesActivity in my application.What I want to do is pop up a ProgressDialog after the user has changed his username or password during the check on the remote server. In the onSharedPreferenceChanged() I call the ProgressDialog.show() method. Sometimes it works fine, sometimes not at all.

I am writing a media player and i would like to have a progress bar showing the progress of the song. I found the ProgressBar class, but all i can get on the screen is a circular spinning icon. what im looking for is an actual bar.
How do i change the style of the ProgressBar to be a bar (not a circle) and how would i use it with MediaPlayer?

I am extending the normal android.widget.ProgressBar.This rotates it fine, however I am having alot of sizing issues. It seems as though I have to set the width and the height of the control to be the same thing or else I run into alot of clipping issues. Basically, I want to have a progress bar that, once rotated, is 50dip wide and fills the screen vertically. Can anyone think of a way to do this? Also, it doesn't seem to be actually drawing the progress properly, but I will revisit that once I get the clipping sorted out.

I have used the progress dialog in order to load the contents from the server to list...But i feel that the progress bar small with "loading..." message that is used in the android market browser ( in dev phone) is better ... here is the problem iam facing..
1) i have a list of 100 names that has to be loaded on to the dev phone.....
I do as follows.....extends Activity implements ListView.OnScrollListener ...
On every request i am getting 20 items and request is sent in seperate thread and for the UI i am using progress dialog saying "Wait..getting details...." and on getting the response progress_bar.dismiss and setting to the adapter as myList.setAdapter (new MyListAdapter(this)) where MyListAdapter extends BaseAdapter....
2) Now i have 20 items in myList ... and the next request for 20 items is sent when i reach the last list item by using the onScrollStateChanged() using view.getLastVisiblePosition();
Similarly as explained above i send request in seperate thread(not the UI thread) and show the progress bar and dismiss it on the response...
But problem is on myList.setAdapter(new MyListAdapter(this)) , the list goes to the first item and the user(here i...) has to scroll back again to the 20 items to see the list..
I did all the above procedure by referring the slowAdapter example in the API DEMOS... So, here is the problem .. 1) how to show the next 20 items without going to the first item on every second request ..
2) i found that android market browser uses same scenario .. but i dont know how to generate it..

I want to know the progress of some download.
When I'm getting some resource from the internet, like this:
CODE:.........
When "InputStream in = httpConnection.getInputStream();" is called, all the content of the file is downloaded at once.
If I use: htttpResponse = httpClient.execute(httpRequestBase); The problem is the same.
How can I detect the actual progress of the download?

I don't understand why I'm getting this error. I'm using AsyncTask to run some processes in the background. I have:

connectionProgressDialog = new ProgressDialog(SetPreference.this);
connectionProgressDialog.setCancelable(true);
connectionProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
connectionProgressDialog.setMessage("Connecting to site...");
connectionProgressDialog.show();
downloadSpinnerProgressDialog = new ProgressDialog(SetPreference.this);
downloadSpinnerProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
downloadSpinnerProgressDialog.setMessage("Downloading wallpaper...");....

I've created ProgressDialog with a second thread according to the DevGuide,changes screen orientation or 2) hits the back button twice (first to hide the dialog, second to hide the app) to hide the application and run the app again after a while.Then, onCreate() is called (for the second time), and progress bar stops responding properly. My thread may work for a few minutes and I want to give the user possibility to hide it and do sth else. After a while he might want to run the app again in order to check the progress.I found a few articles concerning this topic, but I couldn't find the exact solution I should chose for this problem. So, could you tell mi what is the proper way to handle this? Should i save the handler and dialog state with "onRetainNonConfigurationInstance()"? If so, how to do it properly and is it safe?

I am trying to update TextView in my Activity with text messages from DatagramServer ( see below) The problem I have is that "backgound UDP server receives plenty of traffic, but onProgessUpdate is ever executed only once so only the first of the messages appear in the TextView.
public class MyActivity extends Activity {
TextView txtStatus; // txtStatus initialized
new BackgroundAsyncTask().execute();
public class BackgroundAsyncTask extends
AsyncTask<Void, String, Void> {
public static final String SERVERIP = "127.0.0.1";
// 'Within' the emulator! public static final int SERVERPORT = 2222;
private DatagramSocket socket;
protected Void doInBackground(Void... params) {
try { InetAddress serverAddr = InetAddress.getByName(SERVERIP);
Log.d("UDP", "S: Waiting for connection...");
socket = new DatagramSocket(SERVERPORT, serverAddr);
while(true) { byte[] buf = new byte[1024];
DatagramPacket packet = new DatagramPacket(buf, buf.length);
Log.i("telemetry server", " waiting for packet");
socket.receive(packet);
Log.i("received", new Integer(packet.getLength()).toString());
Log.i("UDPServer received:", new String(packet.getData()));
publishProgress(new String(packet.getData()));
} } catch (Exception e) { Log.i("Dbg server", e.getMessage());
} // end of try Log.i("Dbg server", "Dbg server: Done.");
socket.close(); return null;
} @Override protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
//it will never been shown in this exercise...
} @Override protected void onPreExecute() {
// TODO Auto-generated method stub
} @Override protected void onProgressUpdate(String... values) {
txtStatus.append(values[0] + " ");
} }
