Hi,
I have a list view, in that i am adding image view and audio view like whats-app. When ever i add a item to the list view list adapter GetView is calling and total list is refreshing. While i am playing audio if any item add to the list, list is refreshing and audio view is also refreshing but audio is still playing.
Can any one give a suggestion to solve refreshing List view items...?
thanks in advance.

Audio is playing, because the background service is still active. To stop the audio, you would need the instance that is currently "playing", and to stop refreshing, you would need to remove the "UpdateList" handlers.
Both of which, I assume, you don't want to do. So, do this. Instead of stopping the update or refreshing of the list. Hold a reference to the "audio view". Either that, or while refreshing the list check which of the audio is currently in playing mode. Then, change the state of that item and leave the others as they should be.
This would require you to have:
- Static field, to hold the reference.
- Either as a media name, or the instance and so on.
- Handler to update the list.
- Code to check which media item needs to be in "playing" mode once list is rendered again.
You forgot to share the code, it would still be better to share some code blocks so that we can practically help you out.

this is my code:
public override View GetView(int position, View convertView, ViewGroup parent)
{
audioId = _messageList[position].Id;
view = inflater.Inflate(Resource.Layout.MessageAudio, parent, false);
ivPlay = view.FindViewById(Resource.Id.ivPlay);
ivPause = view.FindViewById(Resource.Id.ivPause);
seekbar = view.FindViewById(Resource.Id.seekbar);
seekbar.Tag = position;
seekbar.SetOnSeekBarChangeListener(this);
ivPlay.Click += (sender, e) =>
{
playingAudioId = audioId;
playPosition = (int)((ImageView)sender).Tag;
if (ivPlay.Visibility != ViewStates.Visible)
{
player.Pause ();
ivPlay.Visibility = ViewStates.Visible;
ivPause.Visibility = ViewStates.Gone;
}
int startval = msglistview.FirstVisiblePosition;
for (int i = startval, j = msglistview.LastVisiblePosition; i <= j; i++)
{
if (audioId == GetConversationItem (i).Id)
{
view = msglistview.GetChildAt (i - startval);
if (view != null)
{
playChronometer = view.FindViewById (Resource.Id.playChronometer);
ivPause = view.FindViewById (Resource.Id.ivPause);
ivPlay = view.FindViewById (Resource.Id.ivPlay);
seekbar = view.FindViewById (Resource.Id.seekbar);
PlayAudio(audioPath, seekbar.Progress);
ivPause.Visibility = ViewStates.Visible;
ivPlay.Visibility = ViewStates.Gone;
}
}
}
};
public void PlayAudio(string path, int duration)
{
try {
if (path != null && System.IO.File.Exists(path)) {
player = new MediaPlayer ();
if (duration == 0) {
player.SetDataSource (path);
player.Prepare ();
length = player.Duration;
TimeSpan tm = TimeSpan.FromMilliseconds (length);
string fromTimeString = tm.ToString ("mm':'ss");
time = fromTimeString;
run.Run ();
player.Start ();
} catch (System.Exception ex) {
Console.WriteLine("Exception at playing audio:" + ex.Message);
}
}
return view;
}
public void Run ()
{
seekUpdation ();
}
public void seekUpdation()
{
try
{ seekbar.Progress = player.CurrentPosition;
playingSeekDuration = player.CurrentPosition;
seekHandler.PostDelayed(run, 100);
seekbar.Max = player.Duration;
var fileduartion = seekbar.Progress;
TimeSpan result = TimeSpan.FromMilliseconds(fileduartion);
string timeString = result.ToString("mm':'ss");
playChronometer.Text = timeString;
}
catch(System.Exception e)
{
Console.WriteLine (e);
}
}

After adding an item, are you calling the adapter's notifyDataSetChanged() method?

Are you referring to the Up button in your app's action bar, or the system's Back button?

How is this related to FIFO or LIFO? The back buttons can be somehow confusing, as hardware and logical buttons have a different effect on the transition.
- Logical back would take you to the parent activity.
- Hardware back would take you to the currently previous activity.
So, it would be worth handling both of them in your code. Then loading the activity, with the previous state or from ground up. Read the following two guides to learn more about "proper navigation":

- Handling Back Button Press in an Activity Called For Result[^]

I want to draw horizontal dashed lines programmatically between programmatically generated TextViews. I found this code on Internet:
Paint fgPaintSel = new Paint();
fgPaintSel.setARGB(255, 0, 0, 0);
fgPaintSel.setStyle(Paint.Style.STROKE);
fgPaintSel.setPathEffect(new DashPathEffect(new float[]{5, 10}, 0));
I just copied and pasted this code but nothing happened. What should I do to draw a dashed line? Thanks.

You need to add the code to do the actual drawing of the line. It would be better to study the documentation[^] rather than copying code from random places on the internet.

How to access the file system (SD Card files) of Master device to client devices for file accessing via bluetooth like Bluetooth file transfer application in play store?
please help
|

It had been a negative response until now, and it will be a no unless you start something yourself!
Start here and read the documentation, then learn how to use the protocols to work with Bluetooth connections and devices, http://developer.android.com/guide/topics/connectivity/bluetooth.html[^]
