I'm trying to use a coordinator layout with an appbar layout that hosts a fragment as the "scrolling view". The fragment consists of a recyclerView and a bottom aligned layout holding a button, like so:
However, the bottom section is hidden by default:
and only shows up after I scroll.
From my activity class:
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); TestFragment fragment = (TestFragment) getFragmentManager().findFragmentByTag("Test"); if (fragment == null) fragment = new TestFragment(); getFragmentManager().popBackStack(); FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction(); fragmentTransaction.replace(R.id.fragment_container, fragment, "Test"); fragmentTransaction.commit(); } Activity layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.design.widget.CoordinatorLayout android:id="@+id/main_content" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <FrameLayout android:id="@+id/fragment_container" android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior"/> <android.support.design.widget.AppBarLayout android:id="@+id/appbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> <android.support.design.widget.TabLayout android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" app:layout_scrollFlags="enterAlways|scroll" app:tabGravity="fill" app:tabMode="fixed"/> </android.support.design.widget.AppBarLayout> </android.support.design.widget.CoordinatorLayout> </RelativeLayout> Fragment layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.v7.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_above="@+id/bottomView" android:scrollbars="vertical" android:visibility="visible"/> <RelativeLayout android:id="@+id/bottomView" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:background="#d4285d" app:layout_scrollFlags="enterAlways"> <Button android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Do something..." android:textSize="14sp"/> </RelativeLayout> </RelativeLayout> The end goal here is for the fragment to have the bottom bar always on screen, and the recycler view scrolling the appbar away.
Is this possible?
Thanks all!
