I have a situation where I need to show seekbar in every row of recylerview to download the media(Audio). The file is downlaoding successfully but everytime I click the downlaod button , only the last seekbar of the recylerview work not the seekbar associated with the particular row.
This is my adapter from where I am downloading audio

Check the concept of view tags, that will help you out. basically do a seekbar.setTag("UNIQUE ID FOR EVERY VIEW"); then while updating the seekbar use findViewWithTag("UNIQUE ID FOR PARTICULAR VIEW")
since you are fetching view by id it will only give the last view with that id.

I have tried to make an countdown timer in a list veiw implementation. Each list item has a separate countdown timer that can be started or stopped. However I have noticed that if I add the first timer in list and set its time. When I start the timer it starts two seconds less than the actual time. e.g If I added a count down of 12 seconds. Then it will start counting from 10. But when the countdown is taking place and I add another new timer and set its time, it starts on the exact given time. The new counter starts at the wrong time only when either there is no other counter in the list or when all counters are already stopped and not counting down. Similarly it will only start the right time only when other timers are counting down. Would really appreciate if someone can help me figure out where is the problem. I have been looking at the code for days.
Here's my Adapter class
public class CustomAdapterCounter extends ArrayAdapter<CounterData> {
private final LayoutInflater mInflater;
Context context;

}
}
}
};

super(context, 0, l);

lstHolders = new ArrayList<>();
list = l;
mInflater = LayoutInflater.from(context);

CounterData[] array = list.toArray(new CounterData[list.size()]);
if(!array[i].isStopped)
startUpdateTimer();
}

}
public void setCounterID(int id) {

}

}
}
And I add the time from number pickers of Hour, Minute and Second.
case R.id.counterStartStopButton:
long hour = TimeUnit.HOURS.toMillis(numberPickerHour.getValue());
long minute = TimeUnit.MINUTES.toMillis(numberPickerMinute.getValue());
long second = TimeUnit.SECONDS.toMillis(numberPickerSecond.getValue());
// if(getListSharedPreferences()) {

list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
else {
counterID = 1;
list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
UPDATE
Here's the shared preferences code
public void saveCounterIDSharedPreferences(int id) {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
sharedPreferences.edit().putInt("Counter ID123", id).commit();
}
public boolean getCounterIDSharedPreferences() {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
if (sharedPreferences.getInt("Counter ID123", -1) != -1) {
counterID = sharedPreferences.getInt("Counter ID123", -1);
return true;
}
else
return false;
}
What turned out to work for me was changing the timer task as following:
private void startUpdateTimer() {
Timer tmr = new Timer();
tmr.schedule(new TimerTask() {
#Override
public void run() {
mHandler.post(updateRemainingTimeRunnable);
}
}, 500, 500);
}
Main goal: android app-messendger for chating with company support.
Task: To impliment timers of waiting response from operator or client in listview.
Trouble: In all listview items rendering one of all timer, and then application is listing some timers for a moment are rendering for correctly result, but when they are overlap.

I am making a multi-video downloader. I have created a listview and for each item in the listview an asynctask is called which downloads the file in the background. Everything works perfect. But, if i want to delete an item from the listview for example from position 2, the item at position 3 (both are currently running) comes on position 2 and the asynctask attached previously to position 2 continues running and it shows the progress of asynctask that was previously attached to the position 2. How can I move the asynctask of position 3 to position 2.
Here is my Adapter Class from where I am calling the asynctask class:

you should override the remove method of your adapter in order to cancel properly the asyncTask associated to your item.
i develop downloading app and when I click the save button then download process in back ground but button click not show right position .I have listView in which I inflate a row contain Imageview and button and progressbar now I want to handle click event of button which coded in adapter and I am able to get the position of button too.

On all your button onClicks where you want to deal with the actual button that you just clicked use the View v
