    Arguably the worst part in playing around with Android is its insistence to put that ugly title bar above everything I do as a default to Activities. Thankfully, the framework allows one to change this behavior.This post is going to explore the ways in which we can create custom title bars and more importantly just how far we can push the limits.

Custom Drawing | Android Developers - 1 views

  • Creating objects ahead of time is an important optimization. Views are redrawn very frequently, and many drawing objects require expensive initialization. Creating drawing objects within your onDraw() method significantly reduces performance and can make your UI appear sluggish.

      將物件在初始化時就實例化是很重要的概念，onDraw()的運作速度很快，如困每一個Paint畫圖物件都臨時才在onDraw()產生，將會大幅下降整体程式的流暢效能。
  • If your view doesn't need special control over its size, you only need to override one method: onSizeChanged().
  • is mandatory.

      当自己复写的View写在内部类时，在xml呼叫这个新类是没有用的！

    有什么具体案例么？
  • Simon Pan on 07 Apr 11
     
    这句话是写在第4点 Use the Custom Component中∶ Notice that the MyEditText class is now a separate class file. 1.When the class is nested in the NoteEditor class, this technique will not work. 我还没真实遇到，Diigo先！ 总之告诉我们如果将自己写的View写成内部类时， XML会找不到！

    Using the Eclipse GUI does not allow one to easily: (a) Add custom build steps (b) Use an automated build system (c) Use build configurations (d) Build the release project with one command.Fortunately, the Android SDK comes equipped with support for Ant.This tutorial will show you how to incorporate an Ant build script into your Android projects,even if you still develop with Eclipse.

    "Fragmentation matters to the entire Android community: users, developers, OEMs, brands & networks. It's a blessing and a curse. The Blessing. Fragmentation allows users to take their pick from thousands of devices. You can choose from phones with 3D screens, projectors, CDMA, GSM, or even CDMA & GSM. You may not care that Tag Heuer has made an Android phone but at least one person does (and they use OpenSignalMaps). It's a triumph for Android that as a single OS it can target so many markets. The Curse. The proliferation of devices with their associated screen sizes, internal hardware and custom ROMs creates some difficulties. We spend a lot of time making the app presentable (or at less functional) on exotic devices - this is the most common request we get from app users"

[Android] Defining custom attrs - Stack Overflow - 0 views

android attrs

shared by Vincent Tsao on 14 Feb 11 - No Cached
  • You can define attributes in the top <resources> element or inside of a <declare-styleable> element. If I'm going to use an attr in more than one place I put it in the root element. Note, all attributes share the same global namespace. That means that even if you create a new attribute inside of a <declare-styleable> element it can be used outside of it and you cannot create another attribute with the same name of a different type.
  • An <attr> element has two xml attributes name and format. name lets you call it something and this is how you end up referring to it in code, e.g., R.attr.my_attribute. The format attribute can have different values depending on the 'type' of attribute you want. reference - if it references another resource id (e.g, "@color/my_color", "@layout/my_layout") color boolean dimension float integer string fraction enum - normally implicitly defined flag - normally implicitly defined You can set the format to multiple types by using |, e.g., format="reference|color".
