I was changing view when click button using Layoutinflater.The button have located in the same position in all the screen.
If i click button it change the view only once.If i double click the button it change the view twice.It means click event
dispatched twice in two different layouts.Here when i double click the button it should change only once.
For that what should i do?
Thnx,
You can take diff of two click events, that is store system time of first event in variable ( global scope) and diff it by system time of latest event. Here you need to decide time span between two click events oon the basis of which you consider wether its a double click or not. Say i consider if second click is done within 35 milliseconds of first click event, its a double click.
Thus if the time difference above is less than 35 seconds, you can restrict view change
Hope this would help u

I have a listview where I am capturing both a list view item click (to change available options) and a list view double tap (to move to a new screen). When the user double taps, the event seqeunce is Item Click, Double Tap, Item Click.
The second Item click event is overwriting some of the logic behind the double tap event. What is the best way to disable or cancel the second item click? I thought the "Handled := true" would work but it made no difference.
Any help greatly appreciated
I have an app that has a lot of buttons, and when a button is clicked, it plays a corresponding sound depending on which button was clicked.
I'm doing this by using the name of the button that was clicked to get the internal android resource ID of the sound file with the same name, and playing that sound, all in one method, and eliminating the need to test which button was clicked with a big long switch statement.
Now I want to do something similar to change the appearance of related views (ie. not the button that was clicked but 2 other views related to which button was clicked, once again without the big long switch statement, the difference being that it is multiple views I want to change the appearance of, that aren't passed to the onClick listener.
Any ideas how to go about this?
Thanks
I have a list view and two buttons(play & pause) I want that to when a play button touched a list view's first item go on top of page for example for 6 seconds and next item after first item be on top for 3 seconds and ...
This means Successively items go to top of list view's page and when I touch pause button it stop working and when I touch play button again it continue working
What can I do?
Sorry For my poor English
Sorry
you can keep a track of the last visible item on the screen like a counter. On click of play button increase the value of counter by 1 and set smooth scroll to the counter value. Do this inside a Timer object pass a TimerTask to create a new timer object and schedule it to run over and over again. Hope this helps.

If I have a fragment containing a ListView where each row is a series of clickable elements (say, 3 buttons) filling all available space on the row, can I possibly have a long click callback for the entire row?
I want the user to be able to click on any of the three elements with a quick click but the long click should select the entire row/entry.
I have tried hooking up the ListView with the setOnItemLongClickListener while setting android:longClickable on the individual elements in the layout, but I never see the callback get hit for the long press.
Is this feasible? Do I need to have each element listen for the long click and push it back to the ListView somehow?
Since these three elements(Button) filling up entire space of the , it is difficult to set long click listener for that row...
so good idea is set one same long click listener for these elements rather than row, if they don't have any long click events..
thank you
Put longclicklistener on list view and when that is performed some boolean make true and in your 3elements clicklisteners check if it is false than do other commands.
- Previously i have done showing off the custom Dialog on the clicking of the button on the ListView, but that was at a static location.
- Now i want to display the Dialog dynamically on the location of the button click on the ListView.
- I am not sure about how to find the location of the button on the Screen, cause the click is absorbed by the button, so i can't get the click transferred to the Screen.
- Even if onTouch is implemented, i am not sure about how to find the location of the button which is being clicked on the ListView, cause the click is being absorbed by the button and ListView won't receive it.
- So please help me find out the solution to this tricky situation.
Try to insert the button click listener in the Adapter of ListView, or insert the Object one parameter and insert here when the button is touch and onClickListener get the Object and verify the parameter.
