I need to resize several images inside ImageView to screen size. Currently I use scaleType="centerInside", it works good for bigger images to scale them down to screen size but doesn't expand small images.
All other suggested options crop or deform image. Is there any way to expand images (keeping ratio) via XML or do I have to do it manually in code?

By default, there are only 3 screens for google g1. but i know some applications can expand them to 5 - 7 screens.

I liked the Instinct and it was flawless as a phone. The Evo with its large screen blows it away. Colors on videos and in photos on web browsers are way better. I am a webmaster for a site that is very photo intensive and my opinion is that the Evo colors are very accurate. This is no small thing as our customers need to see the products clearly if they are to make buying decisions. Text in the browser will auto adjust when you expand the screen and I could read articles without my reading glasses which I need for almost everything. These two things make the web actually usable on my phone now.

I want to expand this 3rd text view on the entire screen i.e. i want to show this 3rd text view as a full screen in the same activity above the other text views. Is it possible in Android ?
View 2 Replies View RelatedI use Layout_width="fill_parent" and Layout_height="wrap content". If an image is bigger than the ImageView, it will be downscaled perfectly.
However, I never got it working to upscale smaller images. I tried any combination of ScaleType and "AdjustViewBounds": it always stays in its own size in the middle of the image view. Here is the code...
<LinearLayout
android:id="@+id/LinearLayout02"
android:layout_height="wrap_content"
android:background="@drawable/content_bg"
android:orientation="vertical"
android:padding="5dp"
android:layout_width="fill_parent"

android:layout_width="fill_parent"
android:adjustViewBounds="true"

</LinearLayout>
Is there a way to expand the VM limit in Android 2.0 on an actual device? Using java.lang.Runtime.maxMem() on a Droid reveals a limit of 24MB, and I've written some code that incrementally allocates memory until failure to verify that figure. You can set the VM size in the emulator, but I haven't yet found a way to do that for a connected phone. Is there some type of a properties file on the device itself that can be modified?

I am new to java, eclipse, and android development, so I may be missing something simple although I have checked basic stuff like spelling several times.
Because there is no number picker control (such as that used in the date picker) in the public Android SDK, the conventional wisdom is to "clone and own" the control that exists in the Android source.
In an attempt to do that, I have copied the code for NumberPicker into my project and its dependency, NumberPickerButton. I have also copied the supporting resources.
The problem I am having is that when I try to include the NumberPicker in a layout, the rendered version of the layout within Eclipse does not work.
CODE:...............
Adding that tag causes the Layout view of the XML file to only show the following error.
ClassCastException: com.spencerandbrown.PatientTracker1.NumberPickerButton cannot be cast to com.spencerandbrown.PatientTracker1.NumberPickerButton
I have tried both the fully qualified name and the unqualified name and it makes no difference.
The strange thing is that the control works at run time, it just will not render in Eclipse.
Is there a solution for this issue? Am I just doing something wrong?
If necessary, I can include more code from my project to clarify.
If I reference the internal Android widget, it works fine in the Eclipse layout view, but it is clumsy to interact with that way and it might break in the future.

Here is the stack trace from Eclipse.

View 2 Replies View RelatedBasically I am trying to recreate the default contact screen when you click on "+" button another row of Phone number added to the list. Right now I have an ImageView as the "+" button and a ListView to contain the list of phone numbers. The problem is that the ListView doesn't expand when I add more item into the list. I could build the same look with LinearLayout but how can I save all those numbers that way? Below is the layout of the item that will be inflate with custom Adapter:
<?xml version="1.0" encoding="utf-8"?> <TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="60px"
android:stretchColumns="1" android:background="#FFFFFFFF"
android:gravity="center_vertical"> <TableRow>
<Button android:id="@+id/type" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:text="Home" /> <RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:paddingRight="10dp" >
<EditText android:id="@+id/value" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" android:text="" android:hint="Name"
android:lines="1" android:textSize="10pt" android:typeface="sans"
android:textColor="#FF000000" android:gravity="left" /
</RelativeLayout> <ImageView android:id="@+id/del"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" android:layout_alignParentTop="true"
android:paddingRight="14dp" android:src="@android:drawable/ic_delete" />
</TableRow> </TableLayout>
This is the ListView portion.
<ListView android:id="@+id/phoneList" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#FFFFFFFF"
android:scrollbars="none" />
I have an ImageView, and I want it to be clickable. The image itself is only 32x32 pixels, but I want the clickable region to be larger so it's easier to hit. I was hoping I could set the layout margin values to increase the size of the imageview's clickable area:
<ImageView
layout_width="32dip"
layout_height="32dip"
layout_margin="20dip" />
That doesn't work, what I could do is just recreate the image resource to have a larger transparent region around it. That's a bit annoying because it's hard to tweak if I ever need to change the clickable region. It's not just a single png either, it's a statelistdrawable so I have to resize 3 different pngs if I ever need to tweak the clickable area.
Anything else I can do?
In my app I have nice ExpandableListView. I would like sometime, depending of situation, to expand some or all groups. I would also like to be able to remove/hide groups, expand all and basically have (visually) ExpandableListView without groups. I looked at all available methods for ExpandableListView and couldn't find any that would do what I want to do.

The scrollbar appears at the side as expected, but how do I get the scrollbar to expand and become controllable in the same way it behaves in the Contact list? Ideally I'd like all the Contacts list functionality for my app - i.e. to allow me to control the scrollbar directly with a finger and to show the first letter of the list elements you're currently scrolled to.
View 6 Replies View RelatedI have a ragged hierarchy of parents and children. In that there are some parents that have 5 children...and some parents have 0 children.
The expandableListView displays the "Expand/Collpase" icon even if there are no children.
Question-Is there a way to hide the icon for only those Parents(rows) that have no children? I still want to show the row of the Parents with no children. And allow a user to click on them. But the "Expand/Collapse" icon is confusing.
I am rendering a ListView inside a dialog. The ListView elements are very simple TextView objects. The problem: whatever I do, they never take the full width in the list view, which has the side effect that the list view selector only covers the actual text, not the whole list entry (i.o.w., if the text of the entry is much smaller than the width of the listview/dialog, then only a tiny portion of the list element is highlighted when focusing it).
View 3 Replies View RelatedI have a list view which uses a custom adapter in order to show my custom content. Its layout is the following.

I would like that the listview only showed the view with the ids itemimage and item description, keeping the itemtext hidden.
The idea is to have an onclicklistener on each item of the list, in order to expand that item so it shows the itemtext content. I know I should use Tweening animation in order to expand/collapse each item, but I can't figure out how to do that.
Anyone please help me with some code snippets to slove the problem.If anyone knows how to make an adjustable gridview please help me.

I have a layout like this above textview and an image that slides down after clicking the text view. I have looked at translate animation but the issue is I want the image to start from the bottom of text view and gradually get into its full view. Translate animation doesn't let me start from behind the textview so that it can appear slowly and coming out at the bottom of text view and expanding to its fullview. I have linear layout now with textview and imageview.

Didnt see an existing thread on this; sorry if this is a repeat.By default the SF stores 200 texts per conversation and 20 multimedias per conversion. However, that value can in both cases be adjusted up to 5000. Might be excessive but here's how if you haven't already done it: Open Messaging App>Menu>Settings>Text Message Limit>Tap the number and put in 5000>Set and you're done. **If you put in a value greater than 5000 it still ends up as 5000; must be the limit** With 5000 thats gonna be some really long threads but oh well.
View 4 Replies View RelatedI wonder if there is a way to expand the power buttons "phone options" with things like 'reboot' for example. Yes, I know some themes have this ability, but I am looking just to expand the power button offerings and wonder if there is a root option or file edit or something can do so. Not interested in installing a theme just for this, they are not my gig, so I will pass on that as an option - so if the answer is no then, no worries.
View 9 Replies View RelatedI am using Eclipse Helios Service Release 2 and the project target is 2.2.
I have a xml layout that has a HorizontalScrollView and ScrollView with a LinearLayout. For some reason unknown to me the graphical layout will not expand when I add objects that exceed the size of the default screen size.
I have other xml layout files that will expand when using a single scrollview type, however when using two of them nested together it does not work.
I have attempted to use ScrollView then HorizontalScrollView and reversed to see if it is a order of priority issue with Eclipse. However this does not work.
There appears to be nothing missing from the properties of the scrollviews between those that will expand and the one that wont.
Is there something I am missing? Or is it not possible to have two different scrollview types in one layout and still have a auto expanding graphical layout editor? I would rather not define a specific screen resolution that would allow me to see all objects; I want the app to be adaptable to any device screen size.
