  1. POFrameLayout expended in runtime but its children are not updated with new values
    text
    copied!<p>In my app I use the following FrameLayout as a container for a fragment that will be a footer:</p> <pre><code>&lt;FrameLayout android:id="@+id/frameLayoutFooter" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true"/&gt; </code></pre> <p>In my activity I use the following code in order to add the fragment:</p> <pre><code>FragmentManager fm = getSupportFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); mFooterFragment = new FooterFragment(); ft.add(R.id.frameLayoutFooter, mFooterFragment); ft.commit(); </code></pre> <p>And the layout of my footer fragment 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:id="@+id/footerContainer" android:layout_width="fill_parent" android:layout_height="165dip" android:layout_alignParentBottom="true" android:background="#15355b" &gt; &lt;RelativeLayout android:id="@+id/relativeLayoutTopSetcion" android:layout_width="fill_parent" android:layout_height="wrap_content"&gt; ..... some buttons and imageviews here... &lt;/RelativeLayout&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/relativeLayoutBottomSetcion" android:layout_width="fill_parent" android:layout_height="350dip" android:layout_alignParentBottom="true" android:visibility="**invisible**" &gt; ..... some more imageviews and textviews here... &lt;/RelativeLayout&gt; &lt;/RelativeLayout&gt; </code></pre> <p>At some point I would like to expand the footer and put some more imageviews and textviews in it, but unfortunately all my tries have failed, the result is that the fragment's FrameLayout <strong>does get expanded but its children stays in the upper (old bottom) part even although they have alignParentBottom set to true</strong> - what i get is that the footer's height does change and its bottom newly added part is transparent, which makes me think that the <strong>its children are not updated with its new layout params.</strong> Another thing is that I do see the the change of the mRelativeLayoutBottomSetcion.setVisibility(View.VISIBLE) -but is not in the bottom (the newly expanded section) of the FrameLayout but in the bottom of the original size before expanding.</p> <p>in order to expand the fragment I used the following code from the activity this framents belongs to: </p> <pre><code>ViewGroup.LayoutParams params = mFrameLayoutFooter.getLayoutParams(); params.height = 500; mFrameLayoutFooter.requestLayout(); // setting the bootom relative layout to be visible mRelativeLayoutBottomSetcion.setVisibility(View.VISIBLE); </code></pre> <p>What am I doing wrong ?</p> <p>Is there a known UI pattern for expendable footer ?</p> <p>Thanks in advance</p>
