Android's spinner automatic scrolling when text is too long

In my layout there is a spinner (drop-down list) with fixed width, some entries are longer than the spinner so I want them to automatically scroll horizontally when chosen.
I know you can apply automatic horizontal scroll to textview like this:
<TextView
android:id="#+id/textView1"
android:layout_width="50dp"
android:layout_height="25dp"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="Single-line text view that scrolls automatically if the text is too long to fit in the widget" />
I tried to apply same settings to my spinner as follows:
<Spinner
android:id="#+id/spinner1"
android:layout_width="90dp"
android:layout_height="55"
android:ellipsize="marquee"
android:entries="#array/country_arrays"
android:focusable="true"
android:focusableInTouchMode="true"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true" />
But it doesn't scroll. Any ideas?

A Spinner extends AdapterView which is backed by an Adapter class.
So much like you can customise each row in a ListView, you should be able to do the same for your Spinner by overriding a method like Adapter.getView().
There you could return a simple TextView with the ellipsize property.
Hope it helps you a lot.

Text Animation in android

I want to animate the text of the textview not the whole textview in Android application. I am currently using Marquee property of Android textview but it is not 100% what i want, so i want to animate the text inside the textView so i can handle the events also. If someone with work around on this, please share your answers.
thanks
Here is what i have done at the moment using Marquee
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:duplicateParentState="true"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:focusable="true"
android:focusableInTouchMode="true"
android:gravity="bottom"
android:maxLines="1"
android:scrollbars="horizontal"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="Hello World"
android:textColor="#FFFFFF"
android:textSize="24sp"/>

Android: TextView is not scrolling Automatically

I have a TextView with following attributes :
<TextView
android:id="#+id/appheader"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_centerVertical="true"
android:textColor="#ffffff"
android:layout_marginLeft="3dp"
android:textSize="21sp"
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:focusable="true"
android:focusableInTouchMode="true"/>
Actually the TextView scrolls ONLY when I click the TextView. But I want to scroll it automatically when I launch the Activity. How can I do this ?

<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="very long text to srollll dkfjadkfjkldjfkjdkghjhtudhfjhdjfkdfkadjsajekdfjak"
android:singleLine="true"
android:marqueeRepeatLimit="marquee_forever"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"/>

By-default TextView marquee effect works when it get focus. To make an automatic marquee effect you need to extend TextView class. See this link for reference.

set android:scrollHorizontally="true" for that textview.
Also set the following two properties:
text.setMovementMethod(new ScrollingMovementMethod());
text.setSelected(true);

Scroll a text automatically on horizontal

I want to scroll a text automatically in horizontal way. I tried the method below, but the text was not scrolling.
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#drawable/bg_1"
android:textColor="#cc0000"
android:scrollHorizontally="true"
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit ="marquee_forever"
android:focusable="true"
android:focusableInTouchMode="true"
/>
So please tell me how to scroll a text and if there is any need to add some code in the class file also.

your TextView don´t scroll because their with must be fill_parent, and the other thing is that the textview must be selected (not pressed) to scroll.

Also, beside what Franco told you, you have set android:ellipsize="marquee"(that truncate the text to fit on that single line you have set), so probably that mix up with the scrolling you set by android:scrollHorizontally="true"
My suggestion is to try to remove the ellipsize property.

i put a listview in above textview so the textview is not scrolling. so itried this one
set listview focusable is false
listview.setfocusable(false);
then it works the text was scrolling.

Try this....
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="John Jonathan Samuwell Abbruzzi"
android:singleLine="true"
android:scrollHorizontally="true"
android:textSize="50sp" />
</HorizontalScrollView>

Isn't "ellipsize" a typo? Don't you mean "ellipsis"?

set listview focusable is false
listview.setfocusable(false);
