  <p>My layout is :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical" &gt;
  
      &lt;FrameLayout
          android:id="@+id/realtabcontent"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:layout_above="@+id/tabhost" /&gt;
  
      &lt;android.support.v4.app.FragmentTabHost
          android:id="@+id/tabhost"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
           android:layout_alignParentBottom="true"
           &gt;
  
          &lt;FrameLayout
              android:id="@+id/tabcontent"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
               /&gt;
      &lt;/android.support.v4.app.FragmentTabHost&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>And my Android code is :</p>
  
  <pre><code>mTabHost = (FragmentTabHost)findViewById(R.id.tabhost);
          mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
  
          mTabHost.setBackgroundColor(Color.BLACK);
  
  
          mTabHost.addTab(mTabHost.newTabSpec(HOMETAB_TAG).setIndicator("" , getResources().getDrawable(R.drawable.home_selector)), HomeContainerFragment.class, null);
          mTabHost.addTab(mTabHost.newTabSpec(QRTAB_TAG).setIndicator("", getResources().getDrawable(R.drawable.qr_selector)), QrContainerFragment.class, null);
          mTabHost.addTab(mTabHost.newTabSpec(AROUNDTAB_TAG).setIndicator("", getResources().getDrawable(R.drawable.around_selector)), AroundContainerFragment.class, null);
          mTabHost.addTab(mTabHost.newTabSpec(SHARETAB_TAG).setIndicator("", getResources().getDrawable(R.drawable.share_selector)), ShareContainerFragment.class, null);
          mTabHost.addTab(mTabHost.newTabSpec(MORETAB_TAG).setIndicator("", getResources().getDrawable(R.drawable.more_selector)), MoreContainerFragment.class, null);
  </code></pre>
  
  <p>Thanks in advance.</p>
