I would like to create a button with circular or rectangular background, text and an image below or above the text.I would like to create a CustomButton object with methods setText() and setImage() which would change the button text and image and place multiple CustomButtons into main layout.Does anyone know how to create a custom layout, place it into another layout(main) and modify its elements from the activity which is bound to main layout?

But quick memo is useless for me I'd rather love to start a widget (a tasker task). I tryed several app's and xposed framework modules but I can't get a Widget working with the remapping.
How to remap the volume up hardware button to a tasker task widget?
I've made a little test component that overrides ImageView, called myImageView, and prints some text and an arrayList of Doubles over whatever image is specified in the related xml. However, right now, the text and Doubles that are drawn over the image are defined within the myImageView class. Is there a way to pass the data from the main onCreate function to the myImageView class before the layout is drawn?
I'm new to OO programming, but based on my understanding of this:
http://developer.android.com/guide/topics/ui/custom-components.html
It's possible because ImageView is just like any other class. This leaves me with two initial guesses:
1. I could generate my test data in the main onCreate, and store it in the array's xml file, and then read that xml file with myImageView,
OR
2. I could extend view instead of ImageView, but because of my new- ness, then I would lose the ability to use it in an xml layout sense - and that's what I really want.
Wondering if I'm going about this the right way or not. I have 3 buttons on my screen (Restart, Previous, Next). When the view loads it shows the first image which is fine. When I click the "Next" button I want it to load a second image and so on for up to 9 images. If I click the "Previous" button it should go back one image. Clicking "Restart" should go to the first image. I have the Restart one working. I'm having trouble with the Next button because it only shows the second image (I think because my "a" variable is initialized at 0).
View 1 Replies View RelatedI' have a view that contains several textViews an ImageView and a Button . Because on small screen devices (or in landscape mode on big ones ) not all are visible I use a Scroll as the parent of the whole hierarchy to allow the user to view all the information. The things are suck that the button must be at the buttom of the view . However on big screen device , where it remains enough space at the buttom , the button is put immediatelly below the last textview,and seems to occupy all the remaining space (resulting in an unnactractive view) . Trying to use android:allignParentButtom ="true" not only that it has no effect but it puts the button at top of the screen . Has anyone any ideea how could I accomplish what I described ?

I was looking over this code about extending an ImageView: http://marakana.com/forums/android/examples/98.html
And i was wondering how can i add the new View to an existing xml layout file, along with some other views.
Already i did this inside my main linear layout:
CODE:..........
But the problem is that this way the onDraw method doesn't get called.
Maybe some examples where you combine CustomViews with xml layout.
Is it possible to create a button with a custom xml layout? Now I want to use this on a button. Anyone know how I can do this? I was thinking if I had Button.java file that extended Button. And then setView( R. layout. mylayout.xml); but that was to easy, and it clearly not working
View 1 Replies View RelatedI'm trying to create a button in a custom view that I've created. I'm looping through an XML document and drawing certain things. I want to be able to also create buttons to go in certain locations depending on the xml data. I'd like to do it in the view because I want to be able to call invalidate() on my view to redraw things and replace the buttons when new xml data is available.
The problem is that I put my code in the view class, the activity crashes because the button is "null".
Here is a subset of my code:

I know this code works for creating buttons because I can put it in my activity class and it works just fine. Any suggestions? I thought about relocating the button in the activity, but I can't figure out how to do this when new data is available.

View 2 Replies View RelatedI am trying to make a custom button, having two 9patch files, one for normal state and one for status.
First I tried with a simple 9patch background and the result is fine:
CODE:...................
I get a button with a image and a text bellow it. Everything with the main_button_background underneath
I create a new xml file (main_menu_button.xml) with the following content
CODE:................
The button becomes:
CODE:...............
Now the text isn't displayed, only the background and the imgsomeimage.
I want to create a custom field on which I can place more than one line of text as well as images.
And the field can be used like a button(onclick event etc.)
Can I use a custom view like com.examples.me.customview in the xml file of a app widget and can then draw in the onDraw of the custom view? Or do I have to draw into the drawing cache of an ImageView instead?

View 1 Replies View RelatedI am writing a clock widget that uses customised bitmaps (so the widget loads the bitmap from the sdcard) Just have a couple of questions regarding how updates work:
1. if i want to display seconds on the clock widget will the widget load the bitmaps off the disk every second or can they be cached somehow so it doesn't reload off the disk each time. or If it does reload a bitmap each second, would this use a lot of power?
2. If i load the customised number bitmaps into a static array and then pass them as bitmaps to the widget would this use less power than just loading off the SD card?
I'm attempting to use a custom Android vertical scrollbar widget that seems to work fine in its own example project, but I am having trouble trying to include it into my project. I've exported a .jar from it to use in my project, but it seems to be a minefield of problems, from duplicate resources, to my XML layouts not able to get at styles inside the library, and errors "inflating class" when reading my XML layout file.How should I go about using the widget from another project in my own?Quite new to Java development (know the language, but not much of the overarching project/package management), so if there's some good text regarding that it would be appreciated.

View 3 Replies View RelatedI try to create a widget and I am now wondering how to be able to put a button on my widget and set its "onClickListener". It seems that we are limited to the RemoteViews... OK I can deal with that (but this is a limitat to me) but I'd like to add a button where the user can request an update on the data displayed in the widget. (I get some info on the web but the user only needs to request an update, I can't defined an automatique update, it's useless for my app) I'm sure we can do that since there is an example with a player and obviously with a PLAY/PAUSE button. I was looking for in the remoteViews API btu without finding anything.

View 4 Replies View RelatedI want to use a Button in my android app but I want to customize how it looks. However, I want the highlight and selected colors of the button to be the same as the default colors (i.e. the dark and light orange gradients, or whatever the theme color supplies).Is there anyway to get the default highlight/selected drawables and to use that as the fill for my buttons on the selected and highlighted states?
View 2 Replies View RelatedI'm writing an app that will host widgets. The app has custom view (which probably is the source of issue).mView.addWidget() basically just remembers this AppWidgetHostView instance and then mView draws it directly onto canvas. Visually everything is fine.I can see the actual widget. But the issue is with reacting on UI events. Please advise what needs to be done in the parent view in order to correctly trigger handlers in the widgets like onClick().I used standard widgets which normally react on click events. None worked.I also created my own test widget with listener and onClick()is successfully triggered if the widget is added on Homescreen, but doesn't work in my app.mView correctly detects click event and I tried to call widget.perform Click there, which returns false meaning onClickListener is not registered in the widget. But according to source .would call updateAppWidget which would register its onClick listener.
