I was wondering in what order the following methods - on Draw(), on Measure(), on Size Changed() - are called automatically when we create a custom component. Not sure if this question makes sense. I've just been kinda confused as to what the methods are supposed to do exactly.

I've been quietly lurking around, enjoying my simple 2.2 leak Droid X. But, I've always known that eventually I want to root it and install ROMs and themes and whatnot. The problem is, I don't know the correct sequence of hacks/mods to get to my desired end product. I also don't know what the current best method is for accomplishing each part of the sequence. My desired end product would be something like a rooted Droid X with Vanilla Froyo and flyX and whatever other speed tweaks are available. I'd also like to keep my apps and settings that I have now, if that's possible. What I'm asking for is a simple list of things to do to get to that end product. I don't need the detail of how to do each one, I can figure that out myself (of course, if you want to provide links, that's be appreciated too).

View 4 Replies View RelatedI want to develop and distribute some custom UI components for android apps. This custom component can do some network communicatioon too with my server. So by this I want to hide the communication protocol from my component users, and will show the content as provided by my control eg sponsor ads. This concept is same as Apple's iAD. Issue: 1. I want to hide my custom component code from its users so that they just need to include it in their antivity rest its upto me. 2. I have not implemented but sure that a UI component can do network communication.
I'm reading the android docs on custom component development and i'm a little confused. If you're creating an activity, you can add add a hierarchy of views via setContent. however, if you're creating a custom component, you have to handle everything in the draw() overload.if i want to build a custom component that relies on a view hierarchy, is the model simply to create a hierarchy internally and then in draw call myViewHierarchy.Draw() or something?
View 1 Replies View RelatedI had posted a similar thread a while back and received no feedback, so let me try to be more clear.I am able to use Androids components to build the most basic layouts, which include images, buttons, text areas, etc. These are like Android Lego! I can build the castle. BUT I want to design my own component, my own Lego, that draws on the screen and uses the available area that the Android components have not used. ie, I want to have a top layer of buttons, and the rest of the screen, whatever it is, I want to use to draw 2d graphics. So, I want to make my own Lego, and use it with the other Android Lego. However, I'm also trying to be a good developer and making this for whatever resolution is thrown my way. What is the best way to do this considering the deluge of different resolutions Android developers must cope with? Is there a way to do a table view and return the remaining screen size? Or, am I stuck making an entire new box of Lego here?

I have created a WebView layout, which is used to access a specific website, however it would be useful to edit or create a custom "Web page not available" resource when a handset doesn't have a network connection or the page times out. I know it's possible because if you open the app "Wikidroid" while a handset is in Airplane mode you receive "Article not available" error page instead of the standard Android "Web page not available" error page.
Click here for screenshots of the default and custom error pages. I have search high and low on the internet and haven't come up with any online resources which address this request.
We have in our project a keyboard with "Key" elements, this Key elements have attributes such as android:codes="119", android:keyLabel="w" and so on.My question is how can I include an custom attribute like a "android:alternativeKeyLabel" to do something else.

View 1 Replies View RelatedI would like to create a widget that can reads its attributes from an XML file onCreate. I've created a Custom Button that extends Button widget. I would like to define its layout and styling in an XML, such that the widget can be reused across different views, with the same styling attributes. The notepad sample code does carry some pointers to this problem, however, it defines a XML layout with the component as View, inside LinearLayout, which is not really what I'm trying to achieve here.
View 4 Replies View RelatedIs it possible to create a layout based on (background) images? For example, there is well know app called Appie that uses this picture as a homescreen:
I might be able to recreate the layout with a TableLayout, but this will be difficult to get it perfectly aligned with the buttons in the image. The default layout options make it very difficult, or maybe impossible, to allow for selection of the buttons on the image (especially when the buttons are in an arc-path). Can anyone tell me how this is done?
I wonder how could is possible to make custom shape key on android keyboard. To create custom keyboard is relatively easy, but what needs to be done to create new buttons. They also need to respond with all events as normal keyboard.Any ideas where to start?

View 1 Replies View RelatedI need to implement a JNI which render image with 3-party native function. This function call is time consuming, it cost about 1s to return. I found during that time, even if I call the JNI within another Java thread, the whole Dalvik VM is blocked. UI is frozen. I guess that's because Dalvik doesn't implement Java thread with a native thread, so any time consuming native function call will block the whole VM. I wonder how to solve this problem. My best guess is I should create a pthread in JNI to call that 3-party native function. But I don't know how to implement this kind of JNI.
View 2 Replies View RelatedI'd like to create a custom component which supports voice recognition. (Custom Component which displays voice recognition button if available). It will primarily be an extended EditText which should show the microphone button for voice recognition if it is available. I wanted to to look at the search app-widget on the homescreen but I don't find it in the source. This is intended to use the voice recognition as some sort of dictation device, i.e. the user does not have to type but use his voice instead. So could anyone please point me in some direction?

View 2 Replies View RelatedI have class A, with methods foo and bar, that are implemented by A1 and A2. The functionality in both A1 and A2 is the same. In other words:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} } class A2 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} }
Is it better to keep the code in this fashion, or to swap out those virtual methods as static methods? (In Java, everything non-final/non-private is considered virtual, right?) According to the Designing for Performance section in the Android Developer Docs, I should swap out these virtual methods for static ones. So the above becomes:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} class A2 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} }
Is this how it "ought" to be? I fully realize that I may be misinterpreting this paragraph in the docs.
I wants to create a custom clock widget. Firstly I try to rotate one needle. There is no error found. But IMAGEVIEW stands still.
Here is my widget.java.

Timer timer = new Timer();

I'm writing a custom ContentProvider that serves up content consisting of a single, constant string which I represent as a one-row table having columns _id = 0 and value = "SomeString". This string is not stored in a database, so I developed a subclass of CrossProcessCursor that has does everything required to behave like what I described above.
The documentation for CrossProcessCursor is very sparse and doesn't really explain what the fillWindow() method should be doing beyond the obvious. Based on the descriptions of CursorWindow's methods, I put the following together, which I thought should cover it:
CODE:...............
As expected, it gets called with pos = 0 when a client application requests the content, but the client application throws an exception when it tries to go after the first (and only) row:
CODE:..................
what this method should be doing to return a correct-looking row to the client?

View 1 Replies View RelatedHere is a brief much more complete guide to creating your own Odin images for distributing custom ROMs or making backups. Thanks to kam197, BH_MAN, chadmd23, SoulCreator, and all the other community members.
Requirements:
A Samsung Behold 2 to backup/edit/test ROMs on
Root via try3/asroot2, persistent su, or modified kernel
Working ADB connection
SD Card with ~300MB free
Cygwin - if you are working in Windows
Basic knowledge of a command line
Making the ROM Dump: The Behold 2 has 14 partitions in its flash memory, but only a few of these are useful to modify. You will want to focus on different partitions depending on what you want to do. After you make a ROM dump you will need to package it using the instructions in the following section before you can flash it. Backup your personal data? You may want to backup your data while trying out a different ROM. It is simple to do. Start an ADB shell session and obtain root access. Run the following command to dump the UserData partition: Code:
