how to cancel method of count down timer to stop working - java

I have list of music that user set time to play. I want to have a button to cancel m count down timer .
I test some way but it doesn't work at all.
here is my code to play and set time to play.

}
}
});
return rowView;
}
}
}

make the count down timer an instance variable;
private CountDownTimer timer;
then delegate your count to this variable:
#Override
public void onClick(View v) {
...
timer = new CountDownTimer(result, 1000) {
...
}
}
now you can stop the timer whenever you want to:
timer.cancel();

Check this code, working Successfull
call class from here
timer = new CounterClass(timeInmilles, 1000);
timer.start();
CounterClass is here
public class CounterClass extends CountDownTimer {
public CounterClass(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
#Override
public void onFinish() {
}
public void onTick(long millisUntilFinished) {
}
}
use to cancel see below line
timer.cancel()

How to make customize mediacontroller for videoview

I make whole video player app but stuck at mediacontroller. I want to show my own mediacontroller with different button, not the default one. It's 4rth day, i'm just trying to make my own mediacontroller but didn't succeed.
I succeed by doing it with surfaceview but i want to use it with videoview.
I try the following code.

Lisview inside a Listview not working

I am making an android app that shows weather using OWM 5day 3hour forecast API, The ui consists of EditText to input a city name, a button to initiate the call process, a listview that will display 5 entries (five days) and each day entry includes another listview that displays decription and temperature for every 3 hours in a day,
I am able to see the listview for days but cannot see the nested listview for the hourly data. My classes include : MainActivity, WeatherAdapter to show 3hourly weather, DayAdapter to show day entries, and JsonToWeather data class that extracts data out of the Json response and make an Arraylist of data for only one particular day. I tried to log the error and highlighted the error position by a comment.

You don't want to declare the TextView static if you'll be changing the value.
Try declaring it outside the method here:
public class TicketAdapter extends ArrayAdapter<TicketModel> implements View.OnClickListener{
private ArrayList<TicketModel> dataSet;
Context mContext;

private TextView txtTempsRestant ;

Hi i have a code its good
beucse u dont need definination 3 textview for right and left ,....
You will create one TextView and use this code for create
private void Time() {
mCountTimer = new CountDownTimer(aTime, 1000) {
#Override
public void onTick(long millisUntilFinished) {
aMinute = (int) (millisUntilFinished / 1000) / 60;
mSecond = (int) (millisUntilFinished / 1000) % 60;
mTimer.setText(String.format(Locale.getDefault(), "%d:%02d", aMinute, mSecond));
}
#Override
public void onFinish() {
mTimer.setText(String.format(Locale.getDefault(), "%d:%02d", 0, 0));
mSend_Again.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Your EVENT
}
});
}
}.start();
}

My Count Down Timer is not properly working for Listview in android

When am set Count down timer for single progress circle its work perfectly but when am using it for Listview my Progress Circle not work perfectly. Please tell me How to implement count down timer for listview in android.

Detach isn't working (Two Fragments with FlipView)

I'm working with fragments and flipview but I'm having some problems with this.
When my app opens the first screen show my feed with the FlipView. When I choose another tab of my fragments the fragment of the feed didn't hide or detach. I debugged many times and the code arrives in the detached line but didn't work.
Here is my code
MainActivity class

Please, help me with this!!!
I'm using the FlipView https://github.com/emilsjolander/android-FlipView
Thanks!!!

Finally I solved this problem.
First I changed my Main Class a little.
I changed this two ifs (this fragments uses FlipView) in the MainActivity class.
if (tabId.equalsIgnoreCase(TAB_TAG_FEED)) {
manageContextualActions(true, false);
if (mFeedFragment == null) {
mFeedFragment = new FeedPrincipalList();
ft.add(R.id.realTabContent, mFeedFragment, TAB_TAG_FEED);
} else {
// mFeedFragment = new FeedPrincipalList();
ft.attach(mFeedFragment);
}
}
if (tabId.equalsIgnoreCase(TAB_TAG_M_PROFILE)) {
manageContextualActions(false, false);
if (mProfileFragmentList == null) {
mProfileFragmentList = new ProfileFragmentList();
ft.add(R.id.realTabContent, mProfileFragmentList, TAB_TAG_M_PROFILE);
} else {
// mProfileFragmentList = new ProfileFragmentList();
ft.attach(mProfileFragmentList);
}
}
Second I changed my method onCreateView of my FeedFragment class.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
context = getActivity().getApplicationContext();
((MainFragmentActivity) getActivity()).setupActionBar(R.string.title_fragment_feed);
fbSessionsManager = new FBSessionsManager(getActivity());
if (mList == null){
view = inflater.inflate(R.layout.feed_flipview, container,true);
mFlipView = (FlipView) view.findViewById(R.id.fv_feedFlipView_FlipView);
mFlipView.setOnFlipListener(this);
mFlipView.setOverFlipMode(OverFlipMode.RUBBER_BAND);
mFlipView.setEmptyView(view.findViewById(R.id.empty_view));
mFlipView.setOnOverFlipListener(this);
new LoadFeedPrincipalData().execute();
}
return super.onCreateView(inflater,container,savedInstanceState);
}
You can see the difference. I only inflate the view in the first time. After this my mList(it's a List of MyGetSetClass) it's not null anymore.
And to finish I Override this two methods on my FeedFragment class.
#Override
public void onDetach() {
super.onDetach();
// Log.i("onDetach", "FeedPrincipalList");
mList = null;
timelinePage = 1;
mPageCount = 0;
}
#Override
public void onStart() {
super.onStart();
// Log.i("onStart", "FeedPrincipalList");
this.mFlipView.setVisibility(View.VISIBLE);
}
#Override
public void onStop() {
super.onStop();
// Log.i("onStop","FeedPrincipalList");
this.mFlipView.setVisibility(View.INVISIBLE);
}
In the detach method I clean all my static variables that I will use when I start the app again.
The onStart and the onStop I use to change the Visibility of my FlipView.
That's it.
I hope this help everyone!!!

how to cancel method of count down timer to stop working - java

make the count down timer an instance variable; private CountDownTimer timer; then delegate your count to this variable: #Override public void onClick(View v) { ... timer = new CountDownTimer(result, 1000) { ... } } now you can stop the timer whenever you want to: timer.cancel();
