title: Text Selection in TextView
body: <p>I know there is an attribute <code>android:textIsSelectable="true"</code> which enables text selection in a <code>TextView</code>  by a  long click on text and after that it shows an <code>ActionMode</code> for manipulating text.My question is how can I disable the default <code>ActionMode</code>? I tried to disable it by writing a custom ActionMode and returning <code>false</code> in it's <code>onCreateActionMode</code> method:</p>
  
  <pre><code>@Override
      public boolean onCreateActionMode(ActionMode mode, Menu menu) {
          return false;
      }
  </code></pre>
  
  <p>and passed it to the:</p>
  
  <pre><code>TextView.setCustomSelectionActionModeCallback(customActionMode);
  </code></pre>
  
  <p>It ruined text selection and disabled Start-End pointers.
  I want to disable <code>ActionMode</code> to write my own <code>PopupWindow</code> after selecting text.
  Do you have any suggestions?</p>
