    copied!<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>
