title: EditText : Inserting a tab character
body: <p>As part of my application, I have simple screen for entering text.
  When the focus is in the EditText, it never receives the tab character.</p>
  
  <p>I press on the tab key on the virtual keyboard, but the behaviour is that the keyboard disappears.</p>
  
  <p>Here is my layout :</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical" &gt;
  
      &lt;LinearLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_marginLeft="10dp"
          android:layout_marginRight="10dp"
          android:orientation="vertical" &gt;
  
          &lt;TextView
              android:id="@+id/textView1"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="Intitulé"
              android:textAppearance="?android:attr/textAppearanceMedium" /&gt;
  
      &lt;EditText
          android:id="@+id/etTextTitle"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_marginLeft="15dp"
          android:inputType="textCapSentences"
          android:singleLine="true"
          android:imeOptions="actionNext" &gt;
  
          &lt;requestFocus /&gt;
      &lt;/EditText&gt;
  
      &lt;TextView
          android:id="@+id/tvContent"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="Contenu"
          android:textAppearance="?android:attr/textAppearanceMedium" /&gt;
  
      &lt;EditText
          android:id="@+id/etText"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:gravity="left|top"
          android:layout_marginLeft="15dp"
          android:textSize="25sp"
          android:lineSpacingExtra="4dp"
          android:singleLine="false"
          android:inputType="textMultiLine"
          android:scrollHorizontally="false"
          android:scrollbarStyle="insideOverlay"
          android:scrollbars="vertical"
          android:overScrollMode="always" /&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p></p>
  
  <p>The control in question is the last EditText, as it is multiline, with scrolling.</p>
  
  <p>I need to provide this so that the user can do some (very) basic formatting.</p>
  
  <p>Any ideas ?</p>
