Android :: How To Use Include Tag And Access Views?
Mar 3, 2010
Following is the layout xml file. Here I used <include> tag. in that the layout="@layout/player_view", player_view is another xml file that contains a seat with avatar, 2cards and player name and bet amount. I need 2 seats like that so I used <include> 2 times and it is showing in screen fine. My problem is how to access the views in the player_view to give different names to players and to show different cards for each seat. I didn't find any where how to do that.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/game_background">
<AbsoluteLayout android:id="@+id/game_table" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_margin="30dip"
android:background="@drawable/game_table"

I lose phones... habitually. Sometimes they find their way back to me and sometimes they don't, It is unsettling to me that even if I have a security app installed, or a GPS tracker that ability to perform a google search can simply factory wipe my phone and make it their own.
So the question: Is it possible to include a password requirement to access the bootloader or recovery? I realize that if you forget your password there would likely be no way to save your phone in the event you need to, but I don't forget my passwords so this does not affect me.

I have already developed some widgets for android, but every time, I have the same problem... I Can' access my XML layout's elements from my java code. For example :
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent">
<TextView android:id="@+id/myTxt" android:Text="HelloWorld !" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</LinearLayout>
With this layout, how can I access my "myTxt" object?

I have read the Android UI trick 2 on Android developers, which tells people how to include a layout in another layout file multiple times, and give these included layouts different id. However, the sample here is overwriting the layout id, not the id of the views IN this layout. For example, if the workspace_screen.xml looks like this: And I include it three times in another layout file. Do I end up with three TextViews with id firstText, and another three with secondText? Isn't there an id collision? And how do I find the secondText TextView in the third included layout with findViewById? What should I input in the findViewById method?

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

I want to populate a table, defined in layout xml file through the programmatic way. I have define Table with a single row defining its header, with all the attributes set. Now i want to know a way so that i can just replicate that header row in the table with new content.
I tried using inflator inflate(int,view) method, but at runtime it showed up with error.
Here is the XML code for the layout file defining the table

I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.

How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.

Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Let's say I have a LinearLayout, and I want to add a View to it, in my program from the Java code. What method is used for this? I'm not asking how it's done in XML, which I do know, but rather, how can I do something along the lines of (One View).add(Another View) Like one can do in Swing.

I have a problem trying use <include /> within a table row. Any android:xxxx atributes applied to the widget within the include are ignored. Here's is a test I put together. The two buttons outside the table layout render correctly(adjusted width and height), the one's inside do not. Strangely, the custom TwoStateButton:xxxxx attributes are rendered correctly in both cases. ............

I have some layout xml that looks like this:
== file1.xml == <?xml version="1.0" encoding="utf-8"?> <LinearLayout ...> ... ... </LinearLayout>
I want to include that in some other layout xml, so I do this --
== file2.xml == <include layout="@layout/file1.xml"/>
The question I have is how to pass arguments (and refer to them) from file2.xml to file1.xml. So, for example:
== file1.xml == <?xml version="1.0" encoding="utf-8"?> <LinearLayout ...>
<TextView android:text="@text" android:layout_width="fill_parent"
android:layout_height="fill_parent"/> ... </LinearLayout>
== file2.xml == <include layout="@layout/file1.xml" text="abc"/>

I'm reworking some of my layouts to use Relative layout. I have some building blocks which I'd like to reuse. The problem I seems to have with the include of the layout and position other layouts out of this include. Example:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height=wrap_content"

I have a couple of third party classes which serve as a library I can build my application upon. They are contained in a folder which was added Java Build Path -> Libraries (in Eclipse) with "Add Class Folder". It works fine so far an my app compiles. But the produced .apk contains only my classes and therefore the application does not run. How can I tell Eclipse to package the third party classes into the .apk as well?

I'm building a jar so that other developers can use the view I create in their Android applications. I'm wondering if it is possible to use a layout resource in my jar so I can build the layout of my view or if I need to build up my view programmatically. Similarly, can I include image resources in my jar file?

I am unable to override attributes when using <include> in my Android layout files. When I searched for bugs, I found Declined Issue 2863: "include tag is broken (overriding layout params never works)"
Since Romain indicates this works in the test suites and his examples, I must be doing something wrong.
My project is organized like this:
CODE:..............
The buttons.xml contains something like this:

And the portrait and landscape receipt.xml files look something like:

I've created an Activity subclass called CustomTitlebarActivity. Essentially, each main activity in my app will have a custom titlebar with many common features such as a Home button, a title, a search button, etc. In my current implementation, I am still explicitly using an include statement in the layout XML for each CustomTitlebarActivity: <include layout="@layout/titlebar" />
It seems natural that I should be able to do this within CustomTitlebarActivity. I have two questions: What code can replace this include tag, and where should I put the code? (My first instinct would be to put it in CustomTitlebarActivity's setContentView method.)
On a related note, I would appreciate insight into better ways to reuse android UI code (even if, per se, the titlebars need to vary slightly between activities.)
