Android :: How To Layout Image Buttons In A Grid View From Xml Layout File
Jan 23, 2009
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.
GridView is not behaving like it is supposed to. This screenshot shows that the GridView (in landscape mode) is flushed left. I want it centered. This is the XML layout for the GridView. <Linear Layout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/templatelandscape" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <GridView android:id="@+id/commandsbarlandscape" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1.0" android:layout_alignParentTop="true" android:layout_centerInParent="true" android:padding="0dp" android:verticalSpacing="2dp" android:horizontalSpacing="2dp" android:numColumns="auto_fit" android:columnWidth="52dp" android:stretchMode="spacingWidth" android:gravity="fill_horizontal">
I have a vertical LinearLayout. I would like to layout 1 ImageView on top and 1 ImageView at the bottom of that LinearLayout. I tried putting 'android:gravity="top"' and 'android:gravity="bottom"' in each of the ImageView, but both ImageView appears at the top of the LinearLayout. Is there a way to fix it?
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?
I am beginning developing android application. What I need to know is how to associated a xml layout file with a new class (not the activity). For example the class needs to have a table with an image and some texts.
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?
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 tried so many things to relocate buttons of a list. Relocate the current button is working but the older buttons not. To clarify the situation:
There are two Activities (Activity A and B). At Activity A I customize a button and pass it on Activity B via an intent. On Activity B I move the button somewhere on the screen. This will be done with other buttons. On Activity B I also want to show the old Buttons.code..
As above mentioned, I want to move the Buttons and set them somewhere on the screen (e.g. down right). But everytime I call Acitvity B again, all Buttons are located at top left. I thought it would be achieved with .
This specific layout is just annoying me. And can't seem to find a way to have a listView, with a row of buttons at the bottom so that the listview doesn't extend over top of the buttons, and so the buttons are always snapped to the bottom of the screen.
Here's what I want:
It seems like it should be so easy, but everything I've tried has failed.
RelativeLayout is more flexible, and can do what AbsoluteLayout can do and more. http://developer.android.com/reference/android/widget/RelativeLayout.... To place views on top of one another you can also use FrameLayout, positioning these frame layouts in their parent layout: http://developer.android.com/reference/android/widget/FrameLayout.html

I was told not to use an absolute layout, and use a linear layout instead. However, I am now having an issue with placing the buttons over the picture. The linear layout does not allow me to position them correctly where they need to go. How do I properly position a button so that it is over a certain part of the image?
For second btn , same code has to be repeated with different id? How can I make it generic enough that , it can listen to all buttons (say in for loop) and while handling I should be able to differentiate different btns. (may be get elements id)
I can write a widget with a Button or ImageButton and assign a StateDrawable as background or sourcein order to make an effect when you click it. Besides that I have problems with the side of each button, my main problem is this: how do I change the StateDrawable if I want to change the image of the button from the AppWidgetProvider but still want to preserve the click effect like a StateDrawable. The power control widget in Android does things like that.
I am trying to build a layout dynamically which display some text and image for the most part, but has a series of buttons placed next to each other in the bottom. I have a linear layout that carries the text, another linear layout that carries the image. And yet another linear layout that carries the buttons that get created in a for loop. I have a main layout aligned vertical that adds the text, image and buttons layout, in that order. To finally generate something like this: Text Image Button1 Button2 Button3. The problem is the number of buttons get decided at runtime, so if there are more than 4 buttons, the 5th button gets displayed really tiny. Also, when I tilt the phone, I get only the text and image showing, but no buttons because the image covers the entire screen. Layout thing seems to be pretty complicated to me, any help is appreciated!
My application has some buttons in the bottom part of activity layout, almost the same like iphone has on ipod app for example. I would like to create my layout so that it will self adjust on different screen sizes.
For example if the content in my layout has height = 400dip and the menu bar in the bottom has height = 100 dip, on every screen size (240*320, 320*480 etc.) i would like the menu bar to stay at the bottom so :
- on screen size 240*320 -> 100dip - for menubar -> 220dip - for content => it remains 180 dip to show, so this content area should be in some kind of a scrollview so that i can view 400dip in only 220dip.
I have tested different possibilities, with relativelayout so that the menu bar could stay on bottom, but i could not put the scroll view on top so that the scroll appears only on small screen sizes.
This is so sick, how do you build your layouts for different screen sizes ?
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:
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.)
Im using a LinearLayout to put two buttons horizontally side-by-side, but I want to each button to size itself to use 50% of the horizontal space. I thought layout_weight of "1" for each button would do the trick, but maybe my layout_width needs to be changed?
In my app I want to create something like this: I thought to put five buttons inside a linear layout, but the problem is how to show the inner items at run time. Every time i click on a button i want to show the proper items and hide the others.
My app has 5 different relative layouts that it can switch between by using a set of buttons that is at the bottom of the screen. 3 of the layouts contain only TextViews and ImageViews. The other 2 both have a ListView in them. On the 2 views that contain lists when the soft keyboard appears the buttons that are along the bottom move up to on top of the soft keyboard. But on the other 3 views the buttons get hidden by the keyboard. The buttons all have the attribute android:alignParentBottom="true" does anyone know why they'd be behaving differently when one of these two are the active layout at the time?
