I have a Spinner.Is there a way to display some hint text on it?It seems to default to the first item in its supplied array adapter.I want the user to make a choice, right now it seems like it would assume the 0th item is by default selected.

I use this code to generate a spinner in my app:
code:.........
On my device (Motorola Milestone) and in the emulator this looks like the standard gray spinner widget.
On of my colleagues uses a Motorola Backflip and on his device the Spinner is black. Now its very hard to read the font in the spinner.
What do I have to do to use my own view for the spinner? I don't mind to have the gray spinner on all devices, but it should always look the same on all devices.
I have an xml layout file which contains a few widgets including a Spinner
I want to display a list of strings in the spinner, the list is generated at runtime as a result of a function so it can not be in arrays.xml.
I tried doing:
CODE:...........
But this crashes my application.
I have a spinner 'aperture' set up with a list of numbers, and a spinner 'mode' with two options. When a button is pushed I need a calculation to run using various inputs, including the current selection from 'aperture' and a value derived from 'mode'. How do I call the value of a spinner so I can use it in a calculation?
Also, how do I use the spinner 'mode's selection to set this other value before implimenting it in the calculation? To be more specific, if the spinner is set to Small then the value I use in the calculation is 0.015, whereas if Large is selected I need to use 0.028
My other inputs are EditText views, so right now I am set up like this:
CODE:............
That is not the actual equation, it is just a test to make sure everything connects properly. How would I call the value of spinner 'aperture' and the Small/Large spinner 'mode'
I have a spinner widget in my activity which lets users pick a list name.
Normally, the function of the spinner is to switch between lists but for a couple of instances, I swap out the selection change listener to perform a different function with the same list of options. Once the selection has been made, the old listener is restored and life goes on.
This is a bad and buggy arrangement. Instead, I would like to have a function that just takes a selection listener and some other parameters and shows a popup list that's populated by the same cursor (or and identical cursor) as the spinner, without using the spinner itself.
Is there any way I can do this?
I am trying to populate a spinner depending on another spinner's selected item, my code is the following:
CODE:.................
what is intriguing me is that the first spinner onitemselection works perfectly ( I can see the values in LogCat) then when I change selection of the 2nd spinner I am gettging an error on this line: String selected= (String) s2.getSelectedItem(); So the compiler gets insisde then onItemSelected function of the 2nd spinner but throws an Handler exceltion on s2.getSelectedItem()
why? it works perfectly for the 1st spinner.
I'm considering the use of hints on TextViews but curious to know if hint * bubbles* are possible? (out of the box).

View 1 Replies View RelatedI am supporting search in my app, I'd like to display a unique hint in the search box depending on what activity is being viewed.
To that end, I have a two different searchable.xml files in my xml folder:
CODE:..........
When I reference searchable.xml, everything works as expected. The second searchable xml file has the same contents as the first, but this does not work:
CODE:............
Pressing the search key does not display the search box. If I just reference the first searchable instead, it works fine:
CODE:.....................
Again, both have the same content. It looks like there is a dependency on the name "searchable.xml" within android?
If we're not allowed to have searchables named anything but searchable.xml, how do we specify different hint strings for different activities?
For example:

How to reduce EditText Hint size?
View 1 Replies View RelatedMy EditText configured as follows won't show the hint code...
It works if I set android:gravity="left" or if I remove android:scrollHorizontally and android:singleLine attributes, which is not desirable.
My EditText hint is not wrapping. A hint isn't very useful if the last part is cut off. I am very cautious about restricting/forcing the dimensions my EditText box to ensure it looks decent regardless of screen dimensions. Here's what the relevant xml looks like:
<EditText android:id="@+id/ET1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left"
android:hint="@string/Hint1"
android:lines="3">
</EditText>
I've already set android:lines="3" to mitigate the issue, but it isn't enough. In order to maximize compatibility with various screen dimensions I would prefer OS wrapping over me putting in line breaks and hard returns in the string. There are other things happening in the view which also compel me to not manually set the width of the box to promote good breaks.
In my app i am using edit text. i am specifying hint as well as aligning the text of the edit text using the gravity tag. if i align the text then hint is not shown but if i remove the gravity tag for aligning text then it shows.
please help as to how i can align text as well as show hint..
If there was any way that I could get a hint at the bottom of an Edit Text view -- and then the user to start entering text at the top of the box.
As a bonus question, is there any way I can make the hint NOT disappear once the user starts entering text.

My app includes a search bar. In the first activity the user types into it what they are looking for. What I am currently trying to do is try to change the text hint to the message string. This string contains what the user typed in the previous search bar.

I am trying to get a Spinner to work in Android. It displays fine and I can select any one of the options in the list. But how do I transfer that to a string?I would have thought in the code below that 'selected' would hold the selected string, but I get an 'Illegal modifier for the local class YourItemSelectedListener; only abstract or final is permitted' error on the 'YourItemSelectedListener'.What am I doing wrong?
View 1 Replies View RelatedI have a view with a spinner. The activity starts another acvitity with a popup where I add or delete values that the parent shows in the Spinner.
So, in onActivityResult() I refresh the content of the Spinner so that it reflects any additional or deleted values, by calling my fillSpinner() method.
The parameter to this method is the previously selected value:
CODE:..........
When I open the Spinner, it contains the correct list (i.e. it was refreshed) and the correct value is selected. However, the Spinner control itself (in its closed state) does not show the selected value, but the first in the list.
When I step through the code in the debugger, the Spinner value is correct before and after I call setSelection() (and it is always called with the same correct id). However, since I cannot step out of the event, when I resume the execution after a short moment the value in the Spinner changes.
In other words, the spinner's displayed string is changed and is different from the selected item when I return from my popup activity.
I am thinking of having a spinner with a reversed direction , that's from right to left. Have I to override the class spinner.java ? Cordially.

View 6 Replies View RelatedThe default drop down view of the spinner occupies the entire width of the screen. I tried to create a custom spinner which occupies only some portion of the width of the screen, but I'm unable to do. I want to see the objects behind the drop down. Here is what i tried, I changed the drop down view as,
adapter.setDropDownViewResource(R.layout.simple_spinner_dropdown_item); instead of
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
In the layout.simple_spinner_dropdown_item.xml file I specified the width, but it still occupies the entire width. Can any one help. Is there any other view which is similar to spinner but I should be able to see the background objects like a alert dialog. Is it really possible?
I'm trying to get the value that a user has chosen with the spinner. Can anyone give me an example of how to do this.

View 2 Replies View RelatedI want to apply a non-native font to widgets in my app. This is working fine for TextViews and Buttons, which have a set Typeface method. The code below works just great for my button:
Java: Typeface face = Typeface.gratefullest(getAssets(), "fonts/ my_font.ttf"); play Button = (Button) findViewById(R.id.play_button); play Button.set Typeface(face);
But I just can't seem to figure out how to apply the font to a Spinner.
When we select spinner it shows a display of items which almost the device screen size. Can we minimize its width or height, I think this question was already posted by some one. But I am unable to find solution.
