I want to add a custom height to the dropdown of a Spinner
, say 30dp, and I want to hide the dividers of the dropdown list of Spinner
.
So far I tried to implement following style to the Spinner
:
<style name="spinner_style">
<item name="android:paddingLeft">0dp</item>
<item name="android:dropDownWidth">533dp</item>
<item name="android:showDividers">none</item>
<item name="android:dividerHeight">0dp</item>
<item name="android:popupBackground">@drawable/new_bg</item>
<item name="android:dropDownHeight">70dp</item>
<item name="android:scrollbarAlwaysDrawVerticalTrack">true</item>
<item name="android:dropDownSelector">@android:color/white</item>
</style>
and the code of my spinner is :
<Spinner
android:id="@+id/pioedittxt5"
android:layout_width="543dp"
android:layout_height="63dp"
android:layout_toRightOf="@+id/piotxt5"
android:background="@drawable/spinner"
style="@style/spinner_style"
android:dropDownVerticalOffset="-53dp"
android:spinnerMode="dropdown"
android:drawSelectorOnTop="true"
android:entries="@array/travelreasons"
android:prompt="@string/prompt" />
But nothing seems to be working.
Create a custom adapter with a custom layout for your spinner.
Spinner spinner = (Spinner) findViewById(R.id.pioedittxt5);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.travelreasons, R.layout.simple_spinner_item);
adapter.setDropDownViewResource(R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
R.layout.simple_spinner_item
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="@style/spinnerItemStyle"
android:maxLines="1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee" />
R.layout.simple_spinner_dropdown_item
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="@style/spinnerDropDownItemStyle"
android:maxLines="1"
android:layout_width="match_parent"
android:layout_height="?android:attr/dropdownListPreferredItemHeight"
android:ellipsize="marquee" />
In styles add your custom dimensions and height as per your requirement.
<style name="spinnerItemStyle" parent="android:Widget.TextView.SpinnerItem">
</style>
<style name="spinnerDropDownItemStyle" parent="android:TextAppearance.Widget.TextView.SpinnerItem">
</style>
