Android :: Creating Custom XML Widgets For Android UI
Nov 17, 2010
I'm trying to encapsulate certain layouts that I've made, to help me dry up my android xml ui files. I have the following code:<LinearLayout
android:id="@+id/LinearLayout02"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal">
<TextView style="@style/text_view_small"
android:id="@+id/time"></TextView>
<TextView
style="@style/text_view_small"
android:id="@+id/number_of_worlds">
</TextView> </LinearLayout>I want to simply convert it to the following <DoubleTextView></DoubleTextView> Once done I want to be able to use the "widgit" in other xml files.Are there any particular resources or examples that I can look at to help me figure out how to do this?

I 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.

HTML Code:

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.

Is 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 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'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?

Is there any way to re-use the existing Widgets provided by the default Launcher in a custom Launcher application? At least without going into the main android source tree in order to use the internal classes?

Are widgets currently not supporting any type of custom components? I've tried creating a very simple custom TextView component and it does not work when displaying the widget... Also, can we use the animation classes in widgets?

As a continuation of the thread in http://groups.google.com/group/android-developers /browse_thread/threa, I'm still trying to figure out how a custom widget can use getIdentifier() to read attributes. As an example, I have a widget class called Custom Widget. It has attributes "inner_margin" and "outer_margin". Normally, to read these attributes, I would do the following in source code: import com.example. customactivity. R;// I don't want to do this. TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable. CustomWidget); innerMargin = a.getInt(R.styleable.CustomWidget_inner_margin, 0); Because my CustomWidget is intended to be shared among a number of projects, or even get published, it's a real problem having to import R from whatever activity it's going to be linked with. What I'd rather do is: int resid = ctx.get Resources ().get Identifier ("inner_margin", "int", "com.example.customwidget"); innerMargin = a.getInt(resid, 0); but getidentifier always returns zero. Can anybody tell me the magic I need to perform to do what I want? For completeness, my CustomWidget.xml file that defines the resources looks like this: <?xml version="1.0" encoding="utf-8"?> <resources> <declare-styleable name="CustomWidget"> <attr name="outer_margin" format="integer" /> <attr name=" inner_margin" format="integer" /> </declare-styleable> </resources> and for even more completeness, the entire source code can be found at http://www.efalk.org /tmp/ CustomWidget.tar.gz You received this message because you are subscribed to the Google Groups "Android Developers" group.

I am trying to create a custom dialog in Android. But whatever I tried to do, I am not able to change the width of the dialog. It just remains the same. The following is the view that I am setting as the content for the dialog.

As you can see, everywhere I am using wrap_content in this code sample. Also I tried the following options
1) Setting a custom style while creating the Dialog like this.
dialog = new Dialog(this,R.style.Theme_Dialog);
And the style as follows
CODE:...........
2) Setting the parameters for the view in the onCreateDialog() like this
CODE:.............

I am using:
Android 4.0.3
OpenCV 2.4.2
Samsung Galaxy S2
The face-detection example (from the opencv 2.4.2) is working perfectly. But now, I would like to create a custom layout and actually work with just the data extracted from face detection and build a game on it. Not necessarily having the FdView surface taking the entire screen.
I have done these modifications below, but just a black screen is displayed. Nothing appears on the screen.
Changed the BaseLoaderCallback in FdActivity.java
Code:
//EXPERIMENT
setContentView(R.layout.fd);
FdView surface = (FdView) (findViewById(R.id.FdView));[code]....

Here 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:

I'm redoing my home screen, and I want to have a few text icons that take me directly to specific home screens. Apex launcher has action shortcuts for this, but they are only 1x1. I cannot use widgets to get these actions... I have to use shortcuts. I have done what I want with 1x1 shortcuts, but they are just too small for my taste. I really want 2x1 shortcuts. I have not been able to figure out how to make them with either Simple Text or Desktop Visualizer.

I'm new to Android application development and I'm currently experimenting with various UI ideas. In the image below, you can see a vertically scrolling list of horizontally scrolling galleries (and also textviews as you can see). I'm also doing some matrix and camera transformations which I will come to in a minute.
For the background of the list elements, I use green. Blue is the background of the galleries, and red is the background for the images. These are just for my benefit of learning.
The galleries being used are extended classes where I overrode the drawChild method to perform a canvas scale operation in order for the image closest to the center (width) to be larger than the others. The list view going vertically, I overrode the drawChild method and used the camera rotations from lack of depth dimension in the canvas functionality. The items in the list are scaled down and rotated relative to their position's proximity to the center (height).............
