android - Text Size of a Spinner -

-

how can decrease font size of spinner? have reduced spinner size 35 pix because of text gets cut in half.

how do that? dont want selected beforehand.

default text should "select value".

after tests, there easier way subclassing arrayadapter. change 

arrayadapter<charsequence> adapter = arrayadapter.createfromresource(this, r.array.planets_array,android.r.layout.simple_spinner_item);//this tutorial, adapt line

to line : 

arrayadapter<charsequence> adapter = arrayadapter.createfromresource(this, r.array.planets_array, r.layout.textview);

you have change design of textview use of spinner. tried this, layout of textview.xml : 

<textview xmlns:android="http://schemas.android.com/apk/res/android" android:text="@+id/textview01" android:id="@+id/textview01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textsize="30sp"></textview>
