title: How to display "no result(s) found" using searchview in android
body: <p>Here is my code in "<code>if (cursor == null)</code>." As you can see, I don't put any code there because I don't know how to display "no result(s) found" in the ListView if the user doesn't match his input to the searchview. I'm using ListView to display the search results of the user. </p>
  
  <pre><code>Cursor cursor = mDbHelper.searchCrvJapanesealpha((query != null ? query.toString() : "@@@@"));
  if (cursor == null) {
  
  } else {
  
      // Specify the columns we want to display in the result 
      String[] from = new String[] {
          DBAdapter.KEY_JAPANESECHAR,
          DBAdapter.KEY_JAPANESEALPHA};
  </code></pre>
  
  <p>I'm just beginner with Android.</p>
