I have one spinner in a fragment that have a very annoying graphical glitch. This occurs only on my Nexus 5 with API 21.
I have try to set spinner.setLayerType(View.LAYER_TYPE_SOFTWARE, null) but the glitch is still present. Any ideas?
I managed to work around this bug in two different ways:
Set a style to your spinner:
<Spinner
android:background="@drawable/background"
android:id="@+id/spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="@android:style/Widget.Holo.Light.Spinner"/>
maybe the background color in the predefined styles is enough for you. If not try
Create a shape drawable with a corner radius:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="2dp" />
<solid android:color="#00ff00" />
</shape>
and set it as a popupBackground to your spinner
<Spinner
android:background="@drawable/spinner_background"
android:id="@+id/date_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="false"
android:popupBackground="@drawable/spinner_popup_background"/>
hope this is helpful!
