title: Android Spinner Dropdown arrow not displaying
body: <p>my background for my fragment is white, and the arrow for the spinner does not display unless I click on it.</p>
  
  <p>This is the snippet from my Java file:</p>
  
  <pre><code>    spinner = (Spinner)v.findViewById(R.id.spinner);
      ArrayAdapter adapter = ArrayAdapter.createFromResource(getActivity(), R.array.accounts,R.layout.spinner_item);
      adapter.setDropDownViewResource(R.layout.spinner_dropdown_items);
      spinner.setAdapter(adapter);
      spinner.setPrompt("Select an account");
  </code></pre>
  
  <p>This is my XMLfor the spinner_item</p>
  
  <pre><code>&lt;TextView xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@android:id/text1"
  style="?android:attr/spinnerItemStyle"
  android:singleLine="true"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:ellipsize="marquee"
  android:textAlignment="inherit"
  android:textSize="16dp"
  android:background="#FFFFFFFF"
  android:textColor="#ff252525"/&gt;
  </code></pre>
  
  <p>And this is my layout for my spinner_dropdown_items.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  
  &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@android:id/text1"
  style="?android:attr/spinnerItemStyle"
  android:singleLine="true"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:ellipsize="marquee"
  android:textAlignment="inherit"
  android:textSize="16dp"
  android:background="#FFFFFFFF"
  android:textColor="#ff252525"/&gt;
  </code></pre>
  
  <p>This is how my spinner looks with a white background to my fragment:
