Android :: Include A View Created In Xml File On My Main Layout?
Jun 22, 2010
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...

Currently, I have a layout which contains a Button, a TextView and an EditText. When the layout is displayed, the focus will be automatically put on the EditText, which will trigger the keyboard to show up on Android phone. It is not what I want. Is there any way that I can set the focus on TextView or on nothing when a layout is displayed?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
</LinearLayout>
Since the root element is a LinearLayout, which extends ViewGroup, why does main.xml get turned into a View instead of a ViewGroup? For example, in my main Activity class, I try to get the number of subviews that the LinearLayout contains like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ViewGroup vg = (ViewGroup) findViewById(R.layout.main);
Log.v("myTag", "num children: " + vg.getChildCount());
but it crashes when i call vg.getChildCount(). What is the right way of doing it?

I've a list view with custom list adapter(list_item.xml). I have multiple layout folder to support multiple screen size. I found out when I inflate using LayoutInflater, its always taking the view from main "layout" folder.
I've a phone with screen size "427x320".
This is my code:....................
I want the layout inflater to pick the list_item.xml from "layout-427x320" folder and not "layout" folder.

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.

not sure how to inflate this from my layout file: MyView v = LayoutInflater.from(this).inflate(R.layout.myview, null); the inflater of course does not know what 'MyView' type is, and returns only View. What's a good way to reconcile this?

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.

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 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 have this problem. Two apps: app_a and service_s. Service_S creates file in /tmp. After create this file, service_s uses FileUtils.setPermission to change file mode to 666. Then app_a tries to delete this file. But I always failed when deleting. It seems the files are private. One application cannot delete files which another application creates. Is there any way to delete this file?

I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.

i have tried almost everything i can think of to center a programitacally created table in a pragmatically created layout. I've tried all the usual layout params center setting but still nothing: Score List is a set of pairs of scores (Name, Score). I'm just looping through and adding them to cells in a table and its always aligned left when i run it.
ArrayList<Score> scoreList = new ArrayList<Score>();
public LinearLayout getHighScoresView(Context context) {
final RelativeLayout.LayoutParams layoutParams = new

Use adb logcat, DDMS, or the DDMS perspective in Eclipse to look at LogCat and examine the stack trace associated with your error.

I am creating a layout dynamically when the activity first starts, the problem is when the screen is rotated it is hitting the database again to create the layout. How can I save the layout so it isn't recreated each time the screen orientation is changed?

I would like to have a layout with 5 times 5 buttons. Each of them should have the same width and height (they should be square). And I want the whole matrix to use the screen width (or height, depending on rotation).
I currently do it "by hand" in the Java code:
CODE:...........
This can be improved by obtaining screen width first and then dividing by 5 to get rid of this literal 60. But I'm wondering how I can do this in the res/layout XML file? How can I specify for the height to be the same as the width? (I can set the width to match_parent.)

I was looking over this code about extending an ImageView: http://marakana.com/forums/android/examples/98.html
And i was wondering how can i add the new View to an existing xml layout file, along with some other views.
Already i did this inside my main linear layout:
CODE:..........
But the problem is that this way the onDraw method doesn't get called.
Maybe some examples where you combine CustomViews with xml layout.

I want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?
