i need to reduce the font size and width of spinner that means i need small spinner.below i copy the code of spinner.
my code:in main.xml:
<Spinner
android:id="#+id/fromSpinner"
android:layout_width="100dp"
android:layout_height="30dp"
android:layout_marginLeft="50dp"
android:layout_marginTop="-20dp"
android:prompt="#string/country_prompt"
android:entries="#array/from_spinner"/>
in strings.xml:Choose a Country
<string-array name="from_spinner">
<item>Chennai</item>
<item>Salem</item>
<item>Delhi</item>
<item>Mumbai</item>
</string-array> `
The easier way is to change the your spinner items view when you are subclassing array adapter: don't use android.R.layout.simple_spinner_item
Use
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.planets_array, R.layout.my_item_spinner_layout);
instead of
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.planets_array,android.R.layout.simple_spinner_item)
my_item_spinner_layout.xml look like this for exemple
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:text="#+id/TextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp">
</TextView>
You will need to use a custom view and inflate it using an adapter to get full control.
If you define the array in strings.xml and assign the entries you have limited control. You can have some control using HTML format in the XML itself.
For example: bolding an entry would be (this works)
<item><b>Chennai</b></item>
I don't know if this will work for the size but try it out....
<item><small>Chennai</small></item>
<item><big>Salem</big></item>

The following spinner is still clickable to show the list:
<Spinner
android:id="#+id/spinnerFoo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginLeft="15dp"
android:gravity="center"
android:clickable="false"/>
Could anyone shed some light on this?
I know from my reading that one can disable a spinner by doing it in Java code (spinnerFoo.setEnabled(false). My question is about doing it in XML.
[EDIT]
The following is all the Java code using the spinner:
ArrayAdapter<Integer> adapterFoo = new ArrayAdapter<Integer>(this, R.layout.spinner_item, aiFoo);
spinnerFoo = (Spinner) findViewById(R.id.spinnerFoo );
spinnerFoo .setAdapter(adapterFoo );
spinnerFoo .setSelection(1);
Clickable is not going to stop the spinner from opening because it does not depend on click event.You have to use android:enabled="false"
EDIT
You can set this in the Java code itself, instead of in the XML, because the Spinner should implement setEnabled(boolean) from View
Add this android:enabled="false"
Write this in your xml
android:enabled="false"
I have a Spinner to which I add entries statically. I know I can use an adapter and have a text view for items an so on... But that is not what I'm looking for. What I want is to tell the spinner to break down large items in multiple lines in XML. I just need to know is there any way to do that in layout file or
my ?
here is my spinner which is filled from a string-array:
<Spinner android:id="#+id/spr_my_spinner"
android:entries="#array/my_string_array"
android:layout_height="wrap_content"
android:layout_weight="3"
android:layout_width="0dp"
/>
I have a custom spinner in my Xamarin Android app using MvvmCross. The only reason I'm using custom is because the model holds a class and I want the spinner to populate the values with a property on that class. However, the appearance of the drop down doesn't look like the rest of my app. It's missing radio buttons on the right and the spacing is off. How do I make this custom spinner look just like the rest?
<Mvx.MvxSpinner
style="#style/spinner_input"
local:MvxItemTemplate="#layout/item_spinner"
local:MvxDropDownItemTemplate="#layout/item_spinnerdropdown"
local:MvxBind="ItemsSource ProductCategoryOptions; SelectedItem SelectedProductCategory" />
Item_Spinner.axml - this part seems to be just right, the appearance of the drop down once a value is selected looks just like others.
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/black"
android:text="Test"
local:MvxBind="Text Caption" />
Item_SpinnerDropDown.axml - I think this is the file that is wrong. The appearance of the drop-down doesn't match.
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/black"
android:text="Test"
local:MvxBind="Text Caption" />
Checkable spinners and also supporting activated state indicators is something we've recently worked on within MvvmCross - for example, see this issue and associated commits https://github.com/MvvmCross/MvvmCross/issues/481
To make an MvxSpinner support the default styles then you should be able to simply specify no local:MvxItemTemplate and no local:MvxDropDownItemTemplate - in this case then the spinner uses resources of:
global::Android.Resource.Layout.SimpleDropDownItem1Line
global::Android.Resource.Layout.SimpleSpinnerDropDownItem
This will just use the standard Android layout templates, but will rely on your list item ToString() implementations, rather than using the Caption properties.
This is similar to what the spinner and adapter use within a "normal" Android app - e.g. see http://developer.android.com/guide/topics/ui/controls/spinner.html
Spinner spinner = (Spinner) findViewById(R.id.spinner);
// Create an ArrayAdapter using the string array and a default spinner layout
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.planets_array, android.R.layout.simple_spinner_item);
// Specify the layout to use when the list of choices appears
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// Apply the adapter to the spinner
spinner.setAdapter(adapter);
If you instead wanted to write your own spinner layouts and to base them on the Android layouts then it's probably easiest to look into the Android source to find the original layouts - e.g. looking at: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.4_r1/frameworks/base/core/res/res/layout/simple_spinner_dropdown_item.xml/
One small advanced warning here is that the standard MvvmCross listitem will wrap these displayed list items in a framelayout before using it. This won't have an effect on many layouts - but might effect some. If it effects your's then you may need to write your own custom list item view (based on https://github.com/MvvmCross/MvvmCross/blob/v3.1/Cirrious/Cirrious.MvvmCross.Binding.Droid/Views/MvxBaseListItemView.cs)
One final note on this - please note that https://github.com/MvvmCross/MvvmCross/issues/481 is still open, plus there is a query on the framelayout wrapping of list items in https://github.com/MvvmCross/MvvmCross/issues/539 - so please do be aware that changes and updates may happen in this area - releases in the near future may change the default appearance here.
The following works for Item_SpinnerDropDown.axml
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
style="?android:attr/spinnerDropDownItemStyle"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
local:MvxBind="Text Caption" />
I'm using Spinner in my android app, but I've a problem. It works fine, but its color is darker than they use to have, but I don't know why. Is not a problem with themes or styles, is more, I used Spinners recently for other project and It works perfectly. Did it happen to you? How did you solve it?
I don't use any custom component for this example, so I don't attach the code, but If you need it just ask for.
it may be because you passed different resource id to spinner arrayAdapter.. try passing android.R.layout.simple_spinner_item to your adapter
yourSpinnerArrayAdapter =new ArrayAdapter(this,android.R.layout.simple_spinner_item, your_list);
hope this helps...:)
You can create a custom layout for spinner, it will be more customizable
custom_spinner.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:gravity="left"
android:textColor="#000000"
android:padding="10dip"
/>
And your spinner adapter
yourSpinnerArrayAdapter = new ArrayAdapter(this,R.layout.custom_spinner, your_list);
I have a Spinner which displays single digit numbers (1-6).
When I test on a phone, it's virtually impossible to click on a number because they are so narrow (font size is 12sp) and the only area which appears to be clickable is the text itself.
Ideally I'd like the user to be able click on a greater width on the Spinner drop down than just the text. I've tried padding with spaces but these are suppressed, and I've tried using PaddingLeft/Right but again there's no difference.
Here is the Spinner
<Spinner
android:id="#+id/spinner_period1"
android:layout_toRightOf="#id/spinner_weekday1"
android:layout_below="#id/col1day"
android:layout_height="wrap_content"
android:prompt="#string/enterperiod"
android:layout_width="80dp"
android:entries="#array/periodlist"
android:layout_marginRight="340dp"
android:layout_marginBottom="20dip"
/>
Note that I also set the Spinner text attributes using:
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textview"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textSize="12sp"
android:textColor="#768766"
/>
Any ideas? Thanks in advance

Try making the TextView wider in the android:layout_width attribute.
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textview"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:textSize="12sp"
android:textColor="#768766"
/>
That could possibly fix your issue or make it better at least.
Try setting your TextView layout width to some arbitrary value rather than "wrap_content". That should make the whole thing clickable, as opposed to just the wrapped content.
Just adding some padding to the spinner helped me fix this issue.
<Spinner
android:id="#+id/spinner"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:padding="25dp"
android:scrollbarSize="20dp" />
Way 1:
Display the spinner's options as a dropdown by using android:spinnerMode. Therefore have a look at the API (Android API Spinner). Or play around with android:dropDownWidth.
Way 2 (I used it in an APP but at the moment I have no access to the code):
Maybe you could set another layout while populating your spinner with text - instead of assigning the values in the XML.
Spinner spinner = (Spinner) findViewById(R.id.spinner);
// Create an ArrayAdapter using the string array and a default spinner layout
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.planets_array, android.R.layout.simple_spinner_item);
// Specify the layout to use when the list of choices appears
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// Apply the adapter to the spinner
spinner.setAdapter(adapter);
It's copied from the following link Android Spinner. Maybe you could use one of the layout templates of android.R .
