Android :: Adding Scroll Bar To A Custom ViewGroup ?
Aug 2, 2010I've got the following node in my XML layout:
CODE:.................
TagLayout is a class that extends ViewGroup, and basically holds a bunch of buttons with text (a custom object that act as tags, but that's neither here or there).
The problem is that when there are too many buttons, the view no longer scrolls. I can confirm that I am adding tags but I can't see anything.
If I wrap the above within a ScrollView, the layout never renders. I tried adding the attributes android:isScrollContainer and android:scrollbars, but that doesn't change anything. Is there something I'm missing here?
I should also add that TagLayout is overriding the onMeasure() event. I guess I need to implement a scrolling mechanism there...?
Android :: Adding XML Parameters To Custom ViewGroup
Nov 17, 2010I have a custom ViewGroup that I wrote, and have been able to use it to lay out child elements in code just fine. However, now I'd like to be able to use it for layout in XML. I would also like to be able to add some custom attributes to the XML file to better control my layout. How do I set up, both in XML and in code, a set of custom attributes? Bonus if it can be used with the built in designer in Eclipse.
View 1 Replies View RelatedAndroid :: Custom ViewGroup With Animated View Inside
Jun 17, 2009I want to have a ViewGroup with another View in it. The user should be able to move the other View around the ViewGroup, and fling it away. However, the inner View shouldnt only move, it should also scale and so on (so we dont restrain ourselves to just movements). I don't really know the best way to implement it.
First I though about using a ViewGroup pretty much as it is (i.e. take advantage of the already-written methods). Then I could do the flinging with an Animation. However, when I move the View around with my finger, wouldnt I have to do a requestLayout, since the View changes size when I move it? Or could I just set a transform?
The other alternative would be to override the draw-method and do most of the work myself. For instance, when the user moves his/her finger, I could get a cache of the View and just paint it on the Canvas (with some transform). However, how would I do the flinging then, without an Animation? I could use a Scroller/VelocityTracker, but What would "drive" the repaints? Which is the best way to do this? Also, I won't have just one View, but a couple of them, so I'd like the solution to be effective.
Android :: My Custom ViewGroup Doesn't Scroll Inside ScrollView
Oct 19, 2010I've extended ViewGroup to achieve something like a FlowLayout.I put my custom ViewGroup into a ScrollView, dynamically add a bunch of content and it doesn't scroll.The content that flows off the screen is not viewable.What am I missing, how can I allow my ViewGroup to be compatible with ScrollView?
View 1 Replies View RelatedAndroid : Place Controls At Absolute Positions - Custom ViewGroup
Sep 26, 2010I have a custom ViewGroup. The idea is to be able to place controls at absolute positions and then have the ViewGroup scale those controls based on the difference in the screen dimensions with respect to the original design dimensions. I am using the code below. In response to the 'onMeasure' message, I am storing the width and height of the view. Then on the 'onLayout' message I am computing new dimensions for the child controls and adjusting their sizes proportionally. This all works to some degree. However for certain controls (e.g. button controls), the control resizes, but the text inside does not remain centered within the control. I am thinking that there is some other call I need to make to update the child controls after I change their size.

Mar 29, 2010I'm trying to create a component using an xml layout file. I defined a layout with some custom attributes. This layout is inflated when user add it inside another layout. My problem is I don't know the parent, so I pass null for the parent viewgroup when I call inflate method. I think that's the reason why I see anything in my view. Do you know how can I do (I don't want to redefine onDraw method because I use existing component). Below my xml layout and my custom class.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content">

Dec 22, 2009I have a need to create a control similar to UITabBar in iPhone, which is to be present on every activity of my application. UITabBar essentially is a battery of buttons exhibiting a TAB like behavior: every button maps to an activity. I have two solutions for this: 1. In the layout XML for every activity, I insert a <LinearLayout><Button/><Button/><Button/></LinearLayout> element. And then have a common listener class that will handle the button clicks. So, every activity will have an instance of this listener. 2. To create a custom Widget extending LinearLayout class, put all the buttons as its static members and let it handle the button clicks. Include this custom control in every screen. I am not sure which approach to follow.
