Android :: Include A Second Layout Resource In First One
Oct 6, 2010
Is there a way to include one resource in another (for example a header design in multiple activities' layouts). I know I can add it at run time, can it be done in the XML?

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

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.)

I want to decompose my UI into several XML Layouts. The first one would be the main layout, and the other ones would be the content layouts.
I would like to be able to set which content_layout should be included dynamically during runtime, so I don't want to set a "layout="@+layout/content_layout" in my XML file.
Here are my layouts:
main_layout.xml:
CODE:................
content_layout.xml:
CODE:.......
content_layout2.xml:
CODE:..........................

I have a complex dialog-layout that has to be customized for small screens to decrease its height on such devices. This can easily be achieved by decreasing the height of several single Buttons and Textfields in the layout, each by a small amount. Of course much of the layout still stays the same, so I figured I could use the <include/>-tag. This was the idea:
/res/layout/dialog_layout.xml ==> includes "@layout/include_button_layout"
/res/layout/include_button_layout.xml /res/layout-small/include_button_layout.xml
I figured that android would choose which button-layout to include at runtime. I couldn't get it to run, so I guess I was wrong. And if so, can anyone confirm whether this is the way to do it?
/res/layout/dialog_layout.xml ==> includes "@layout/include_above_buttons"
==> includes "@layout/include_button_layout_default"
==> includes "@layout/include_below_buttons"
/res/layout/include_above_buttons.xml
/res/layout/include_below_buttons.xml
/res/layout/include_button_layout_default.xml
/res/layout/include_button_layout_small.xml
/res/layout-small/dialog_layout.xml
==> includes "@layout/include_above_buttons"
==> includes "@layout/include_button_layout_small"
==> includes "@layout/include_below_buttons"

I have in many of my screens that re mostly constructed of LinearLayouts a FrameLayout that should take up the bottom leftovers of the screen (using layout_height="0dp" layout_weight="1") inside it there's a FrameLayout with gradients background and in it's middle with some padding lies a button with some text, naturally i need the text and onClicked properties to me different from screen to screen. I considered using <include > tag for the above compound in my layouts, but as far as i can see i can't really change (at least not in xml) the button text and callback, is that really so?

I want to create a grid of images with text right below the images.
I created in a xml file a image_text item which basically is a linearlayout with and imageview and a textview right below.
I created a tablelayout and I want to add my custom image_text.xml to the table row. But I dont know how to reference my xml file inside. If I use the include statament, how do I pass the image id and text to my item_text.xml? code...

I'm interested in instantiating a LinearLayout object from an xml file that has a LinearLayout file configuration. I want to do this within a method of my Activity. I tried findViewById() but that returned null. I've made sure that the LinearLayout id is the one I'm passing. Note that this layout isn't part of my screen, it's stand-alone, so I want to build a LinearLayout object from the xml.

This seems like a simple problem to me, but I can't figure it out. I have a fullscreen layout that displays differently if the screen is taller (854 instead of 800 pixels). I've tried putting the xml into layout-notlong-hdpiand layout-long-dpi respectively, but both my WVGA and FWVGA emulators go for the "long" version (as described in the doc).
Is there any way to distinguish between the two besides using the deprecated -800x480/-854x480 qualifiers?

I have created a custom list item layout just like in this article http://developer.android.com/resources/articles/layout-tricks-efficie....
Each list item has icon, title and summary.
I would like to declare an xml resource that would provide data for that list. Just like you use <string-array> to populate the list using ArrayAdapter<String>.
The simple ArrayAdapter<String> can be populated from:
CODE:..........
I need each <item> to have icon, title and summary. Somewhat similar to:
CODE:..........
I would use <menu> but menu doesn't have summary if I'm not mistaken.

Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations.
Given the config.xml:
<resources>
<string name="config_somePadding">50dip</string>
</resources>
How would I reference this to use as the layout_height in a layout xml file?
@string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.
In the sdk, they use an integer for animation duration. They reference it like this: android:duration="@android:integer/config_longAnimTime". Is there a way to use values that aren't integers in the layout_height attribute?

I need to display a list of categories from a ListActivity. My data source is a ArrayList of type Category which is implementing the android Parcelable interface. stucture is given at the bottom. it has an id and a title
I need title to be displayed as list text and on clicking the list item, i need to get the id for further processing
It is possible to create a new array of 'title's by iterating the category ArrayList and use
CODE:..........
But bu using this method i will get only the title of the category upon click and not the id.
Is it possible to directly use the ArrayList of objects as data source?

I have an XML resource file:
<resources> <section>
<category value="1" resourceId="@xml/categoryData1" />
<category value="2" resourceId="@xml/categoryData2" />
<category value="3" resourceId="@xml/categoryData3" />
</section> </resources>
Using XmlPullParser, on the START_TAG, I can use:
int value = parser.getAttributeIntValue(null, "value", 0);
to get values 1, 2, 3...however:
int resourceId = parser.getAttributeIntValue(null, "resourceId", 0);
doesn't work...it just yields the default value 0, or whatever I change the default value (3rd parameter) to be. Does anyone know what I am doing wrong or if this is possible?

While developing for Android, I am unable to open more than one main.xml file in an Eclipse editor at a time.Each time I open one, it simply replaces the editor (tab) of the first main.xml with the new one, instead of opening a new tab - even if the contents of the existing tab were unsaved.Even stranger, I can open multiple main.xml files from different projects with no problems.This only happens when they're within the same project.

Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.
I want to do this entirely in an xml layout file. When I put ImageButton xml tags inside a GridView xml body, The layout panel in eclipse is throwing an exception: UnsupportedOperationException:addView(View, LayoutParams) is not supported in AdapterView.

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 am using eclipse 3.5 with the ADT plugin.when I view layout xml files, i get two tabs in the view the source code view and a graphical view.the graphical view almost never works for any of my layouts.it usually shows "NullPointerException: null" at the top and nothing else. when it does work, it often does not match what i get in the simulator or device.it seems like this thing simply is not ready for prime time; although the idea is very cool.has anyone else had much success with it?
