Android :: Changing Values Inside Layout Included With Include
Oct 28, 2010
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've been attempting to use the <include> tag in some layouts and it seems that these are of limited use because of the flat namespace of the R.id.x approach.
Suppose I have a layout (attribs and xml namespace decl omitted for clarity).
CODE:.......
Now in my java code I have a conundrum. I am not able to identify each individual instance o f the children included layouts root view. In the include tags I can replace the root id with "row1" and "row2" so I can find the individual linear layouts using findViewById
eg:
CODE:.........
However, I can't easily access the two instances of the TextView which are children of row1 and row2 because all I have to play with is the single id "text"
ie:
CODE:..........
In this case, which instance (row1.text or row2.text) does this refer to, both of them, or none?
I guess I would need to use another means of accessing the children of row1 and row2.

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"

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'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:

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 an Android library project that makes calls to PreferencesManager.getDefaultSharedPreferences.
I have 2 version of my app, paid/free, and they are not able to access the preferences stored by the library code.
Can someone tell me the right way to store values in SharedPreferences in library code and have the values available to projects that include the library?

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"

Im creating a custom layout and I want to use the text declared in the layout.xml file in my layout.
Like when I create a TextView in XML and set android:text=@string/text1 when I run the app text view automatically loads the text from android:text. So how can I access attributes declared in the layout XML file in my custom component.

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?

Right now I have a class that extends LinearLayout and builds the view inside of the constructor using a series of addViews. I wanted to move this into an XML file, so I have the same view defined there. My problem is that I can't figure out how to load the XML file in the constructor of the derived class. I looked up the LayoutInflater stuff, but I wasn't entirely sure how to use it in that context. Do I need to call addView() with the result of the LayoutInflater? Is this even possible? The other issue is that the context object that is passed in doesn't have the LayoutInflater methods. I'm not sure if I need an instance of Activity to do that.

I am trying to display a bunch of image icons in a grid view, with some basic inductive text on the top. This layout is inside a tab pane. For some reason my application just Fore closes without any stack trace when I do this. Here is my lay out file and the corresponding code that uses it in a tab.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:id="@+id/welcomeLayout" android:orientation="vertical"> <TextView android:id="@+id/txtWelcome" text="@string/app_name" > </TextView> <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:id="@+id/welcomeGrid" android:horizontalSpacing="10dp" android:numColumns="auto_fit" android:stretchMode="columnWidth" android:gravity="center" android:columnWidth="120dp" android:verticalSpacing="15dp"/>

How do I set up an xml layout where an OpenGL view is part of it? As I do now is set the OpenGL view as the only view with setContentView(). But I would like to create an xml layout that includes the OpenGL view. Lets say I want to have the OpenGL view mainly and a small TextView at the bottom.
Is this even possible? Or can an OpenGL view only be the one and only view?

I'm able to successfully use a ScrollView inside the layout xml file for an application. However, when I tried using a ScrollView inside the layout xml file for a widget, I get a "Problem Loading Widget" error as soon as I drop the widget in the emulator. If I comment out the ScrollView, then the widget shows up in the emulator. I've pasted my layout xml file below. Any thoughts on how to get past this error would be much appreciated.

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'm trying to build an activity that has a checkbox on top, a button at the bottom, and a bunch of other widgets scrolling in between. Conceptually that'sWhen it renders I get the checkbox at the top, the stuff scrolling nicely underneath, but the Button drawn offscreen (I assume) below the ScrollView. The only way I can get the Button to be visible is to hard-code the height of the ScrollView, which of course only works on one screen-size. I've tried all combinations of gravity and layout_weight I can think of to no avail. Am I using the right combination of Views? Anybody managed to get this working?
