Collapsible Toolbar - Make Fragment Footer Always Visible in Android
I am making an app that has a ProfilePage with three fragments - About | Posts | Gallery, and I am using a collapsible toolbar with user's image. My second and third fragment will have a footer that should always be visible, but this is what I get:
When my image is expanded the footer disappears. What I want is for my two fragments to have these footers always visible and not depending on toolbar being collapsed or not. My gallery footer should be similar to post footer.

My PostsFragment (not yet implemented):
public class MyProfilePostsFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.navdrawer_my_profile_fragment_posts, container, false);
return view;
}
}
Solution
I had the same requirement for my one of apps. I just did workaround.
Add your required layout in tab layout:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="256dp"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
contentScrim="?attr/colorPrimary"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="@+id/profile_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:contentDescription="@string/profile_photo"
app:layout_collapseMode="none"/>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin">
<ImageView
android:id="@+id/toolbarEdit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end"
android:contentDescription="@string/block"
android:paddingEnd="20dp"
android:paddingStart="5dp"
app:srcCompat="@drawable/ic_icon_edit" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.design.widget.TabLayout
android:id="@+id/myProfileTabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
app:tabContentStart="72dp"
app:tabGravity="fill"
app:tabMode="scrollable" />
<android.support.v4.view.ViewPager
android:id="@+id/myProfileViewpager"

<-- Your required layout -->
<LinearLayout
android:id="@+id/tab123"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:gravity="bottom"
android:orientation="horizontal"
android:visibility="gone"
android:weightSum="4">
<EditText
android:id="@+id/inputMsg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="3"
android:paddingLeft="6dp"
android:paddingRight="6dp" />
<Button
android:id="@+id/btnSend"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="send" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
Add following code in your Tab activity:
TabLayout tabLayout;
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);//add your viewpager to TabLayout
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
LinearLayout l=(LinearLayout) findViewById(R.id.tab123);
final EditText text=(EditText) findViewById(R.id.inputMsg);
Button send=(Button) findViewById(R.id.btnSend);
if (tab.getPosition() == 0) {
l.setVisibility(View.GONE);
System.out.println("About tab");
} else if (tab.getPosition() == 1) {
l.setVisibility(View.VISIBLE);
System.out.println("Posts tab");
send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String msg = null;
msg = text.getText().toString(); //get input
// Perform your desired task.
}
});
} else if (tab.getPosition() == 2) {
l.setVisibility(View.VISIBLE);
System.out.println("Gallery tab");
send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String msg = null;
msg = text.getText().toString(); //get input
//Perform your desired task.
}
});
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
