  • android mobile development performance vs extensibility

    - by mixm
    im developing a game in android, and i've been thinking about subdividing many of the elements of the game (e.g. game objects) into separate classes and sub-classes. but i know that method calls to these objects will cause some overhead. would it be better to improve performance or to improve extensibility?

  • Intercepting touch events on activity and button on Android

    - by hgpc
    I have an Android activity with an ImageButton. I would like to execute some logic when the button is clicked and show a different image for the pressed state, but also receive the touch event on the activity. By default only the button receives the touch event. If I set the clickable attribute of the button to false then only the activity receives the touch event. What's the best way to receive the touch event in both the activity and the button?

  • Android: how to share code between projects signed with the same certificate

    - by tomash
    In Android documentation concerning code signing we can read: "By signing multiple applications with the same certificate and using signature-based permissions checks, your applications can share code and data in a secure manner." How exactly such code sharing can be done? Is it possible to release main application and multiple exchangeable plugins then discover them at runtime? What does source code looks like and what are advantages over "standard" intents calls from/to different APK packages?

  • New to Android - Drawing a view at runtime

    - by Brian515
    HI all, I'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here. Thanks in advance!

  • Will <include> override the layout_width/layout_height value?

    - by Johnny
    I have a layout xml file named my_layout.xml, in which the root view's layout_width and layout_height has been specified as 200px. <com.jlee.demo.MyLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="200px" android:layout_height="200px"> If I used this xml to be included in another xml, and specify the layout_width and layout_height as 100px. <include layout="@layout/my_layout" android:layout_width="100px" android:layout_height="100px"/> What would be the real width/height of my_layout?

  • Android Custom PopWindow/Dialog

    - by Kilnr
    I'm trying to get a completely custom Dialog or PopupWindow, without any of the default Android UI controls (title, background, buttons, whatever). Is this possible at all? I've spent hours searching for this, but no luck... It seems like this should be easily possible, but I can't find it. Preferably this would be by inflating a View from XML, but at this point anything that would just work would be nice. Thanks.

  • Android button font size

    - by jonhobbs
    Hi, I;ve been trying to create a custom button in android using this tutorial - http://www.gersic.com/blog.php?id=56 It works well but it doesn't say how to change the font size or weighting. Any ideas? There was another question on here and the only answer was to use html styling but you can't change a font size in html without using css (or the deprecated font tag). There must be a better way of setting the pixel size of the font used on buttons?

  • How do I lock the layout of my android program to one orientation

    - by Mike V
    I'm trying to write a program that needs smooth orientation sensor samples as the phone is rotated all around. Every time the orientation of the phone is changed, it interrupts the data and freezes the program while the layout changes. How can I lock it in one orientation (landscape or portrait, it doesn't matter)? I assume it has something to do with android:layout in the xml file, but I can't find anything online.
