Spinners moving

Hey guys,
I'm in the process of writing my first android app and something really strange is happening. I'm using a TabletLayout with the first two rows have spinners. On the third row, however I have an EditText box. Now, whenever I type in the text box, the spinners start to move in unison to the right. I have no idea what could be causing this and I don't even know where to look so I'd really appreciate your help.
Sorry for the horrible video quality. I didn't want to install video capture software on my work computer(yes, this is for work though this app is totally just to get me familiar with the tools) and I'm running MM's Gingerbread rom on my N1 which doesn't have hd video recording yet.
Here's the xml file
Code:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
<TableRow>
<TextView android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="Convert from:"
android:gravity="left" />
<Spinner android:id="@+id/from"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"/>
</TableRow>
<TableRow>
<TextView android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="to:"
android:gravity="left" />
<Spinner android:id="@+id/to"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</TableRow>
<TableRow>
<EditText android:id="@+id/value"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Enter value"
android:gravity="right"/>
</TableRow>
<TableRow android:gravity="right">
<Button android:text="submit" android:layout_height="wrap_content" android:layout_width="wrap_content" android:textSize="24dip" android:id="@+id/submit" android:gravity="center|right" android:layout_gravity="right"></Button>
</TableRow>
</TableLayout>
Thanks so much,
Samuel Maskell

apparently embedding the video didn't work
here's the link

Here you go, under EditText, replace
Code:
android:layout_width="wrap_content"
with
Code:
android:layout_width="fill_parent"

well that was simple..
worked like a charm
Thanks,

Menu Inflate XML problem

Hi, first post here & I did search for an answer first
I'm trying to add a menu to my app, in my onCreateOptionsMenu method I can use
menu.add(0, 1, 0, "Text1");
menu.add(0, 2, 0, "Text2");
etc
It works OK & when I press the menu key it pops up, the onOptionsItemSelected method correctly detects the item selected.
If I try to use the MenuInflater on an XML file, it does not work. When I press the MENU key, it pops up a menu with blank buttons - no text or icons & the number of buttons corresponds to the number of ITEM entries in my XML. The XML looks valid .
Any ideas where I'm going wrong. I would paste the code, but the forum says I cant until I've made more posts.
Thanks.

Still new to this myself, but in my recent menu tries, i had to put in a TextView into the xml to tell it what to say.
<TextView
android:text="@string/menu_button1" />
And define the name you want on that button under the strings file.
<String name="menu_button1">New Game</String>
I may be completly off so take what Im saying with a grain of salt lol

Hmmmm, tried that & it didnt work either. Thxs for the suggestion.

Not a problem the book i have at home had me do some menus, i could post the books complete code later maybe i missed something with what i told you. Its in pdf form so it wouldnt be a big deal. Ill be getting home in around 3 hours.
Maybe its a combination of button and textview together to actually make it work. It was pretty easy last time i did it so im sure its just a small detail being missed. I've slowly learned eclipse isnt able to catch every single error.

is your menu's xml file in the res/menu folder? if not it prob wont work

Yup res/menu

Here is the code for the menu from my book.
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:background="@color/background"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:padding="30dip"
android:orientation="horizontal" >
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_gravity="center" >
<TextView
android:text="@string/main_title"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="25dip"
android:textSize="24.5sp" />
<Button
android:id="@+id/continue_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/continue_label" />
<Button
android:id="@+id/new_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/new_game_label" />
<Button
android:id="@+id/about_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/about_label" />
<Button
android:id="@+id/exit_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/exit_label" />
</LinearLayout>
</LinearLayout>
And the strings file
Code:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Sudoku</string>
<string name="main_title">Android Sudoku</string>
<string name="continue_label">Continue</string>
<string name="new_game_label">New Game</string>
<string name="about_label">About</string>
<string name="exit_label">Exit</string>
</resources>

Thats pretty close to what I'm doing, but not exactly. The main difference seems to be your using a LinearLayout & my code uses RelativeLayout. OK, I'll try your code EXACTLY when I get home later. Thanks.

When you say menu, you are referring to the options that pop up when you press the hardware menu button, right?

I ask because... what does that linearlayout code have to do with a menu?
Are you implementing this function?
onPrepareOptionsMenu(Menu menu) {
MenuItem option 1 = menu.findItem(R.id.opt1);
...
}

I thought the Layout may affect how the menu text & icons were displayed & was why I couldn't see them.
No I dont implement onPrepareOptionsMenu, only onCreateOptionsMenu and onOptionsItemSelected - I'd post my code but the forum wont let me yet
I'm following the example from Android Developers "Creating Menus" which only has those 2 methods detailed.

OK guys I've fixed it !!! You'll never guess what it was.......
.... OK, I'll tell you then
In my menu.xml, I had the menu namespace xmlns URI as https not http, I had copied & pasted this from another website. Changed it back & we are working again.
Thanks for the assist - Thanks have been awarded.

Oh man thats a killer...I've had that happen to me a couple of times already
Good example android.text instead of android:text...lol
Glad to here its working though,good luck with the rest of your app.

lol - I either need more or less caffeine - not sure which.
Thanks bud.

Problem sizing image to button.

I'm having problems sizing an image to a button. I want it to be sized (to fill the button) dependent on whatever phone it might be run on, but the image seems to be huge on the screen an dnot even fit on the left and right sides. Below are 2 different code snipets from my main.xml, but neither work:
1st attempt...
<LinearLayout
androidrientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView android:id="@+id/ImageView01"
android:src="@drawable/grim"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:scaleType="center">
</ImageView>
</LinearLayout>
2nd attempt...
<LinearLayout
androidrientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageButton
android:id="@+id/widget30"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/grim"
>
</ImageButton>
</LinearLayout>

just do a "Button" instead of an "ImageButton", you can also adjust the size of the button/image by changing the font size associated with it.

[Q] layout help

I just started to build my app's layout and I'm confused, so I could use a little help.
I want it to look like this:
- there's a bar with buttons which always stays on the bottom of the screen (like position:fixed in CSS)
- there are two (or more) lists with a dynamic number of records which will mos definitely overgrow the screen size, so I need a scrollbar on them. These will not push down the button bar.
This is easy as hell, I know, but I'm not sure how to do it properly so I won't need to change it later.

It's all about learning to love (and hate) RelativeLayout
http://blog.maxaller.name/2010/05/attaching-a-sticky-headerfooter-to-an-android-listview/

Yeah, should just be a ScrollView with a nested RelativeLayout putting your buttons on the bottom...not too painful

I have a problem with my ListView. I want it to be full size without a scrollbar (the parent of ListView is scrollable), but it shows up really short (only 1.5 rows fit in). Here's my code :
Code:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@id/top_controlbar"
android:layout_above="@id/bottom_controlbar">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<!-- GEOTASKS -->
<LinearLayout
android:id="@+id/geotasks_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginTop="10dp"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="30dp"
android:text="@string/main_header_geotask"
android:textSize="18sp"
android:background="@color/header_bg"
android:textColor="@color/header_text"
android:gravity="center"
android:layout_marginBottom="5dp"
/>
<ListView
android:id="@+id/list_geotasks"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<TextView
android:id="@+id/empty_geo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/main_empty_geo"
android:textSize="15sp"
android:paddingLeft="5sp"
/>
</LinearLayout>
etc, same for timed and simple tasks
I tried changing the height of the parent layout and the listLayout (all 4 combinations), but it didn't help.

Well **** my rusty sheriff's badge. I can't believe nobody knows the answer.

ScrollViews are weird. The way they stretch to fill content is not intuitive.
I can't remember the solution off the top of my head but do some googling for "ScrollView" and I think there are some answers on stackoverflow.
hth

My problem is not the scroll view, but ListView. Scrollview stretches without problems.
I want to achieve a simple thing - make the ListView display all of it's content without scrolling. How is that not possible ? OMG
At first I used LinearLayouts and added new views to the root layout. That was very ugly and I couldn't register those views for context menus. Then I found out about list views, and I couldn't be happier if I could just do this one thing.

Sorry I misunderstood what you were asking.
What's the point of having the parent of a ListView scrollable anyways? I think you're just thinking about things in a strange way and that what has got you stuck.
ListView has an addHeaderView() addFooterView() if you need static items at the top and bottom, and you know how to put bottom and top control bars using relative layout, why not eliminate the ScrollView?
I think you're making things difficult on yourself by putting something scrollable inside something scrollable.
Your other option is to use views like you were using them, they do support context menus: http://developer.android.com/reference/android/view/View.OnCreateContextMenuListener.html
Hope that helps.
Edit: btw, the reason I am recommending it this way is that even if you override ListView's onTouchEvent, I dont think it will expand to wrap all the content and be scrollable by the ScrollView. Instead it will just sit there as an unscrollable listview that leaves the user unable to reach the content beyond what they can see originally.

[Q] Multipule screen size

Hi guys, I hope that this is in the right place.
So I have been making an app for a few weeks (First one) and I had no idea that android apps was not responsive to screen size. OK not so bad. I have come from HTML CSS and PhP so that type of thing is a constant battle!
I did some digging and found out a few things, I found this sizing.
xhdpi: 720px by 1280px
large-hdpi: 640px by 960px
hdpi: 480px by 640px
mdpi: 320px by 480px
ldpi: 240px by 320px
When I first started creating the app I stuck all of the images in the mdpi folder! and well that did not work. So following the guide I rezied all of the images put them in those folders to the right size ect I also created all of the same layout folders.
layout-small
layout-large
laout-normal
layout-xlarge
not forgetting to add what was needed to the manifest
Code:
<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true" />
Before I did this things would move around not the images but the text would jump around on smaller or larger phone sizes looking nothing like what it does in Eclipse. So after adding all the new folder ect I loaded up the emulator and got up a small phone, and it looked great, I emailed the app to myself to test on my phone again, and things are all out of place (The text) The images are in odd shapes too.
on what I would call normal phone sizes the text is still moving around and is not going into the positions that I set them to.
I do hope this makes sense! I a little tied!
Thanks guys, hope to get this issue sorted very soon

I can't really tell what the problem is without looking at the layout XML, but off the top of the head, did you use "dp" and "sp" units to keep the sizing relative?
What kind of layout did you use? Are the positioning absolute or relative?

You could also create different layout folders, but I think that the problems are in the layout files. If you post them (or one of them), we will be able to help you better.

When I was rezing the images I was using an online image editor, I set them all into px.
Here is the layout for one of the xml files,

Thank you for this.
I think that the problem are lines like these:
Code:
android:layout_above="@+id/TextView04"
android:layout_marginBottom="156dp"
You use a margin. Now, on a bigger phone, this margin is smaller. That's causing the issues.
With screenshots (one showing the layout how you want it and one how it is shown on big screens) we could help you better.
One thing for the meantime: Have a look at dimension resources. You can put these files into directories like values-large and values-small, too. (More on that: Link)
Btw, the link is the android namespace which is the same in every xml file. (For Android development you don't have to know what it is. Just don't remove it in your file. )

Wihtout the Margins ect how would the text be place into the right places? (Taking knowlage from html and css =D )

No. It wouldn't be placed right. There need to be some changes for the margings. You could define them as a dimension resource. And those can be put into /res/values-small, /res/values-large and other folders like these.
As I said above, with some screenshots we could help you better. (You can replace all texts and images if you want. )
Maybe some other layout would be better. But we can't tell you without any screenshots.
