You can do this in the layout for your Adapter with a ColorStateList. You can create a ColorStateList using xml in your color resource folder like so:

<?xml version "1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android/com/apk/res/android">
    <item android:state_checked="true" android:color="?attr/colorAccent"/>
    <item android:state_selected="true" android:color="?attr/colorAccent"/>
    <item android:state_pressed="true" android:color="?attr/colorAccent"/>
    <item android:state_activated="true" android:color="?attr/colorAccent"/>
    <item android:color="?android:attr/textColorPrimary"/>
</selector>

Then you can create a layout using the ColorStateList (I use it here for the text color, but you can set any attribute that can use a color resource):

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="wrap_content"
    android:padding="16dp" android:textSize="16sp"
    android:textColor="@color/selector_accent"/>

Lastly, set this layout as your drop down view resource:

dataAdapter.setDropDownViewResource(R.layout.view_selectable);

As for the NumberPicker, it doesn't look like there is a standard way to set the layout, but you should be able to change the color of the text, based on this answer. Then just set the text color using your ColorStateList:

editText.setTextColor(ContextCompat.getColorStateList(this, R.color.selector_accent));

for example you have 30 item in list view then if(this) show 1,4,5,6,30 item elseif(this) show 10 28 17 45 item ............. if yes then how — misbah, Jul 22 '16 at 02:51
@misbah That looks like an entirely separate question. The question stated above is just how to change the color of the text within a spinner and/or a number picker, which I believe I answered. What you are asking now seems like you want to apply a filter to your list view based on the spinner item clicked? Anyway, if you are asking a new question, post a new question. Link to it here in a new comment, and I will take a look at it. — Bryan, Jul 22 '16 at 12:31
