I have a TextView in my xml layout file. I'd like to get it and change my text when I click this button.
But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ?
My friend and i develop a Android program.
Now we got to the question if it's possible to get the actual position of an ListElement.
Example: You drag the list up and down, and now you want to konw which element is on the center of the screen?
Does it exist an Android view equivalent to a "<select>" HTML input element ? In my application, user should fill a form. I know that ListView can display a list of elements but I think it's not relevant for a form.

View 1 Replies View RelatedIn one of my Activities I have a ListView that displays a list of locations. For each list item I want a little arrow icon that points in the direction of the corresponding location. I implemented this icon by extending ImageView. This custom View has a listener that reacts to changes of the device's orientation by rotating the icon image accordingly. I register the listener in the onAttachedToWindow() method and unregister it in onDetachedFromWindow(). This kind of works but the problem is that onDetachedFromWindow() sometimes gets called only a long time after the containing Activity has paused. Also, the whole layout overall seems a little hacky. So my question is: Is there a proper way to unregister the listeners or would you implement this in a completely different way to begin with?

I have a custom Android view which overrides onTouchEvent(MotionEvent) to handle horizontal scrolling of content within the view. However, when the ScrollView in which this is contained scrolls vertically, the custom view stops receiving touch events. Ideally what I want is for the custom view to continue receiving events so it can handle its own horizontal scrolling, while the containing view hierarchy deals with vertical scrolling.
Is there any way to continue receiving those motion events on scroll? If not, is there any other way to get the touch events I need?
In hierarchy viewer there are several IDs as shown above, for example "id/timepicker_input".
But I can't find a respective timepicker_input - ID when typing
myNumberPicker.findViewById(android.R.id. ...? );
So how to access these Views by their ID?

View 4 Replies View RelatedThe View class has a compute Scroll method whose documentation states: Called by a parent to request that a child update its values for mScrollX and mScrollY if necessary. This will typically be done if the child is animating a scroll using a Scroller object. See
http://developer.android.com/reference/android/view/View.html#compute...
I am using the 1.5 SDK and I do not have access from within my application to the mScrollX and mScrollY protected member variables of the View class. However, I must have a custom scroller object for my view.
I'm implementing custom widget exdending a View class. But I've found that View's protected field (e.g. mLeft) is not accessible from subClass
View 2 Replies View RelatedI'm trying to do basic authentication to view a protected url. I want to access the protected url which looks like this:
http://api.test.com/userinfo/vid?=1234. So I do the following with a WebView:
mWebView.setHttpAuthUsernamePassword("api.test.com", "", "me@test.com", "my password");
mWebView.loadUrl("http://api.test.com/userinfo/user?uid=53461");
but the authentication doesn't seem to work, I'm just getting an output error page. Am I using the WebView method correctly here?
Update:
Trying with curl: curl -u me@test.com:mypassword http://api.test.com/userinfo/user?uid=53461
and it pulls the page fine. I tried every combination of the host parameter, the owners of the api don't know what I mean by 'realm' though (and neither do I) - what info could I give them to help this along?

View 3 Replies View RelatedI don't know the priorities of the android team but to me this looks like a really significant bug. As reported here: http://code.google.com/p/android/issues/detail?id=2539&q=Widget&colsp.and here: http://code.google.com/p/android/issues/detail?id=3696&q =Widget&colsp.and a few other places in different wording. Apart from it not working anything like the documentation specifies, it disables two methods in the widget provider class, creates potentially huge redundancies/wasted cpu usage and pretty much makes any widget that uses a config activity a bad piece of software. Further yet, the problem with screen real estate failures (first link, my post) applies to ALL widgets, config activity or not. The entire widget framework is effected by these limbo widgets and it seems like something really small, perhaps a few lines of code to fix, considering you display Toasts and other things, the failure paths are already known, should it not just unbind these widget ids on failure? Also as a small suggestion, considering you know the minimum dimensions of the widgets before they're added, widgets could not even be shown or grayed out if the screen can not accommodate them. I notice the "Add" in the Menu does this but only when the screen is completely full, if there is any space left, a larger widget can still be chosen to add, even though it's guaranteed to fail.
