title: how to set back ground color of view to white
body: <p>I want to set background color of view to "white" but it is black. How do I do this? I tried it that way:</p>
  
  <pre><code>@Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      View someView = findViewById(R.id.myScreen);
  
      // Find the root view
      View root = someView.getRootView();
  
      // Set the color
      root.setBackgroundColor(android.R.color.white);
  }
  </code></pre>
  
  <p>and main.xml file is...</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:orientation="vertical"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:id="@+id/myScreen" &gt;
  
      &lt;Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/Button" android:text="Play Sound"&gt;&lt;/Button&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
