Android :: Make Top Row Of Grid View Nonscrollable
Jun 26, 2010
I have a GridView of 9 rows of which the first one is sort of "header" row.As there are 8 more rows they flow beyond the end of screen and need to be scrolled down to.However this scrolling also causes the first row to go "off-screen".Was wondering if there is any way I can prevent the first row alone from being scrolled off?I dont want to make this a separate LinearLayout as it is part of a dynamic View (the GridView) that I create at runtime.
I have a GridView that displays thumbnails of images, I want to change the thumbnail size (zoom in/out) during runtime, what is the best way to achieve this? I changed the columnWidth of gridView during runtime but after that I scroll the gridview and I get memoryoutoferror exception.
What I want is a central column using Grid View, but everything I try does not work. It always aligns to the left. I have tried messing around with layout_gravity and gravity to no avail. I have a Grid View in a Linear Layout: <Linear Layout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent".
I want to display the number of images according to one number.That means if number is 1 i want to display only one imageview in grid,if number is 3 i want to display the 3 images in grid .But i take only one image that means depending on the number that image will be displayed.
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">
Not allowing horizontal spacing between grid view item, I am using following for grid view, I don't want horizontal space between grid view item. android:horizontalSpacing="0px"android:verticalSpacing="0px"
By using this there no vertical space between item. But the horizontal space remain there, how to eliminate this horizontal space between grid items.
My purpose is to set headers for related items of grid view and for this i am thinking about to set the width of grid view different for header and sectional view's.if any other way 2 set sectional header for related items is possible?
I'm have a custom GridView Array Adapter. The problem for me is that when the grid list gets large enough to scroll off the screen the gridview and arraylist get out of sync. For instance in my case I have code that checks if an actor is of type director the text color should be red. if you scroll up and down my list enough times all the actors text in my gridview will become red. The thing is that the Gridview appearance actually looks fine its the backing data. Here is the complete class. In the code you can see where I tried to override getItem and getItemId but that didn't fix anything. Code...
Is there a way to re-arrange the applications list in grid view in alphabetical order? If I switch to "list view", they are in alphabetical order, but in grid view, they are not. I could not find a way to do it.
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 an XML layout with some custom tabs, a heading, and a ProgressBar(main.xml). I wish to add another XML layout(home.xml) to the main.xml layout, as i wish to keep main.xml re-usable for other activity's layouts and simply add things to it as necessary.The problem: after inflating R.layout.home into rootLayout, it seems as though the ProgressBar contained in rootLayout is hidden underneath the content of home.xml.Is there a way to tell certain views(via XML) to float above other views when the layout is constructed in this way?if not, am i forced to use methods such as progressBar.bringToFront() to raise targeted views to the top?what alternatives do i have in z-ordering views when some layouts are constructed using inflation?
does any one use ASTRO?i feel the tab view in this software is very nice and i want to imitate it. i find that this tab view is like TabHost,but the tab can sroll from left to right. this tab view is based TabHost or based gallery+imagebutton?
My app, among other things, downloads and displays images from the Internet. Some might be too large and trigge an OOM when ImageView.setImage() is called. Of course, this normally makes the application to crash. I've put catch (OutOfMemoryError e) around the method invocation. I know that catching errors is unusual, but in JSE applications it proved to work pretty good, especially when the problem was due to image manipulation that consumed all the memory. The Android app seemed to survive for a while, but then it blocked the computer. All buttons are irresponsive, even though the phone seems still alive (e.g. it's playing the audio notification that new email has been spotted). I tried holding the power button, it triggered the shut down menu, but touching a menu option didn't do anything. Only after a while, the phone became responsive again.
Now, it's reasonable that one can't display everything on a smartphone; I'm sure there's some inefficient memory management I'm doing (perhaps keeping too many images in memory); ok, I have to improve my code. Given that I'll do, how can I add some safety facility to avoid the most severe consequences? Making an irresponsive application it's a 100% sure way to make people to uninstall my app and give bad reviews. I'm thinking of a two-pronged safety approach: 1) whether it's possible to understand in advance whether an image is too large to be rendered by itself; 2) whether it's possible to recover from an OOM in any case.
I need to make a list view as shown in the sample pic for my android app. How to do it? Also I need to add image along it as seen in the sample pic. and link it to another view to show some more details.please check links shown below.
I am trying to see if someone can help me with a simple list view I am tying to make. I am specifically facing problem trying to introduce a new column in this list view. Label 3 in xml code below is the new column I m trying to make. Should I have a new linear layout and wrap two text views in it or is there some other option? code...
I'm trying make a View that divide the screen in three sections. The first section should be 200dip high, the third section should be 50 dip high and the middle section should take the remaining place in the middle. Is there any way to implement it? I tried some ways but either it doesn't work or the app crashed.
I have Acvtivity that creates view and mediaplayer. I want to use OnCompletion event to make that view clickable. But it throws exception, I don't know why. Probably, mediaplayer runs in another thread and cannot access elements from main ui thread?
