body: <p>How to set my first value (default value) in spinner as empty. Means, until the user selects value from list, spinner will have no value. I tried below </p>
  
  <pre><code>list.add(""); 
  </code></pre>
  
  <p>But, it won't work. Below is my code : </p>
  
  <pre><code>if(values.contains("options")){
         spinner.setOnItemSelectedListener(MyClass.this);
         List&lt;String&gt; list = new ArrayList&lt;String&gt;();
         list.add("");
         list.add("Test");
         list.add("Working");
         ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(mContext, android.R.layout.simple_spinner_item, list) {};
  
        adapter.setDropDownViewResource(R.layout.custom_spinner_list);
        spinner.setAdapter(adapter);     
     }
   }
  </code></pre>
