title: How to change the weight size of a fragment in android?
body: <p>Here is the xml-Layout of my fragment view</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:orientation="horizontal"
      android:weightSum="100"
       &gt;
  
      &lt;fragment
          android:id="@+id/menuFragment"
          android:layout_width="fill_parent"
          android:layout_height="match_parent"
          android:layout_weight="70"
  
          class="com.pack.Menufragment" &gt;
      &lt;/fragment&gt;
  
      &lt;fragment
          android:id="@+id/bodyFragment"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_weight="30"
          class="com.pack.BodyFragment" &gt;
      &lt;/fragment&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Now I want to change the fragment weight size from the java not from XML, is there anyway to do this?</p>
