title: ViewPager not supporting layout_height = wrap_content
body: <p>I'm building an android application with the following layout.<img src="https://i.stack.imgur.com/x1LVx.png" alt="application layout"></p>
  
  <p>It's already known that <code>layout_height="wrap_content"</code> doesn't work for the ViewPager. </p>
  
  <p>My question is how to change it dynamically. The content of the ViewPager is inflated from two xml layouts, <code>vp_statistics.xml and vp_campaigns.xml.</code></p>
  
  <p>here's the xml for the ViewPager</p>
  
  <pre><code>&lt;LinearLayout
              android:id="@+id/topcontent_wrapper"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:layout_marginTop="10dp"
              android:orientation="vertical" &gt;
  &lt;/LinearLayout&gt;
  
  &lt;LinearLayout
              android:id="@+id/viewpager_wrapper"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:layout_marginTop="10dp"
              android:orientation="vertical" &gt;
  
              &lt;android.support.v4.view.ViewPager
                  android:id="@+id/viewpager"
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Here's the code for my PagerAdapter</p>
  
  <pre><code>class MyPagerAdapter extends PagerAdapter{
  
  @Override
  public int getCount() {
      // TODO Auto-generated method stub
      return 2;
  }
  
  public Object instantiateItem(View collection, int pos){
      LayoutInflater inflater =     (LayoutInflater)collection.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  
      int resId = 0;
      switch(pos){
      case 0:
          resId = R.layout.vp_statistics;
          break;
      case 1:
          resId = R.layout.vp_campaigns;
          break;
      }
  
      View view = inflater.inflate(resId, null);
  
  
      ((ViewPager)collection).addView(view, 0);
  
      return view;
  }
  
  @Override
  public void destroyItem(ViewGroup container, int position, Object object) {
      // TODO Auto-generated method stub
      ((ViewPager)container).removeView((View)object);
  }
  
  @Override
  public boolean isViewFromObject(View arg0, Object arg1) {
      // TODO Auto-generated method stub
      return arg0 == ((View)arg1);
  }
  
  @Override
  public Parcelable saveState() {
      // TODO Auto-generated method stub
      return null;
  }
  
  }
  </code></pre>
  
  <p>and inside my onCreate() mthod of the Activity class:</p>
  
  <pre><code>MyPagerAdapter adapter = new MyPagerAdapter();
  ViewPager viewPager = (ViewPager)findViewById(R.id.viewpager);
  viewPager.setAdapter(adapter);
  viewPager.setCurrentItem(0);
  </code></pre>
  
  <p>Is there a way to get the height of the <code>vp_statistics.xml</code> and <code>vp_campaigns.xml</code> layouts and assign it dynamically to <code>ViewPager (@id/viewpager)</code> every time the <code>instantiateItem()</code> object gets called?</p>
