I want to do a custom action when pressing on the Menu button on the phone.
Is it possible to set an onClickListener (or similar) on the button and if so, how?
onCreateOptionsMenu is only called the first time the button is pressed - I've already tried this.

View 15 Replies View RelatedIn my layout xml file I have set the android:onClick attribute for a Button element to a function in my activity. So when I click the button the function is called with a View as its argument. Are there any information in that View argument that has the id of the button being clicked? I'm trying to figure out if I have to have one onClick function for every element or if I can use one function and switch depending on the id of the element being clicked.

View 1 Replies View RelatedUsing WebViewClient and/or the WebChromeClient you can get a listener for when the page has loaded, however this is sometimes called before the WebView has any content in it, before it has displayed anything. What would be a efficient method for determining when the WebView has displayed it's content? When I load a page in a WebView, I want to set the scroll to a specific position. It seems that the scroll position cannot be set until the page is loaded and it has an actual content height. So, I have tried two different approaches to determining when the page has finished loading, onPageFinished() from the WebViewClient and also onProgressChanged() from the WebChromeClient.
Both of these tell me when the page has finished loading. However, the problem is that sometimes it is called before the page has been displayed and therefore the page has no height and the scroll call does nothing. I am trying to find a solid way to determine when the page is ready to be scrolled, i.e. when it has its content height. I imagine I could setup a checking loop after it finished loading to keep looking for when the height is available but that seemed like quite the hack. Hoping there is a cleaner way.

I am writing an application that listens to phone calls and perform some tasks when phone call arrives. The Application contains one activity which includes 2 buttons 'Start' and 'Stop' (where starts register the listener and stops unregister it - see code below).
The problem starts when the application is closed ( onDestroy is called ). If the user pressed on the start button and exit from the application the listener still working (which is the expected behavior) but from now it is impossible to unregister the listener since launching new instance of the application create new instance of phoneListener.
My question is:
1.Is there better way to implement my requirement?
2.Can I save the phoneListener object and reload It on application creation?
CODE:........................
I have an application with a single Activity implemented as a singleton (in the AndroidManifest). It implements a Listener I wrote. When the application is first run the Listener works fine. When I use the "home" button to minimize it, then open it again it's still fine.
But when I press the back button then run it again from the application icon, the Listener doesn't work fully. The code runs and the Listening methods are called as usual but none of the UI elements that are listening update. It requires a restart of the phone to get the listener working again after this point.
I know the "back" button doesn't really close the application, per se. But resetting the phone sure does! Is there a way to use the onDestroy() or similar method to call a function that actually closes the application? I'm asking because restarting the phone is the only way to get the listener back so I was hoping I could do that programmatic ally.
For example, my progress bar is a member variable of my Activity, but onCreate() I do "progressBar = (ProgressBar) findViewById(R.id.progress_bar);" Is this perhaps creating a separate instance of it or something?

View 1 Replies View RelatedI need to set up a simple event listener to refresh a listview from once in a while. The problem is I don't know how could I generate an event.
I know that for events like key or button pressing I just need to implement the handler. But in this specific case I actually need to generate the event, which will be fired everytime another running thread of my app wakes up and refreshes it's list of news from a rss feed.
I've done everything, but got stucked in here. Can I get any suggestion or link with some more info on how to implement this?

View 2 Replies View RelatedI've looked everywhere for a solution to this, but I can't figure out how to implement it. My OnItemClickListener was disabled somehow on my ListView rows, because I have an ImageButton in the row layout, which takes over the focus. There have been numerous questions I've found, but none of them have gotten me anywhere. I've checked this question, but I couldn't really make heads or tails of it. I just need a way to get the rows clickable so that I can detect when a row is pressed. Long press and focus work fine.
