Android Spinner Dropdown arrow not displaying

This works for me, much simpler as well:

<Spinner      android:id="@+id/spinner"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:theme="@style/ThemeOverlay.AppCompat.Light"      android:spinnerMode="dropdown" />

And in your class file:

spinner = (Spinner) view.findViewById(R.id.spinner);ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.spinner_data, android.R.layout.simple_spinner_dropdown_item);adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);spinner.setAdapter(adapter);

Hope this helps ;)

Try this one:

<Spinner     android:id="@+id/spinnPhoneTypes"     android:layout_width="0dp"     style="@android:style/Widget.Spinner.DropDown"     android:layout_height="@dimen/thirtyFive"     android:layout_marginLeft="10dp"     android:layout_weight="1"     android:background="@drawable/shape_drop_down_normal"     android:gravity="center_vertical" />

shape_drop_down_normal.xml

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android" >    <item>        <shape>            <solid android:color="@android:color/transparent" />            <stroke                android:width="1dp"                android:color="#6f94c7" />            <padding                android:bottom="10dp"                android:left="2dp"                android:right="10dp"                android:top="10dp" />        </shape>    </item>    <item>        <bitmap            android:gravity="end"            android:src="@drawable/drop_arrow" />    </item></layer-list>

Check if you are giving a background for your Spinner and if you do remove it and it will solve the issue
