AppBarLayout take space after setVisibility(View.GONE)

Question

I want to hide my AppBarLayout for adding a view dynamically which will take the height of the screen. For this, i want to remove a view temporaly by setting the visibility of my AppBarLayout to GONE. The view is not visible, but take space in the screen(half of the height of screen).

My XML code :

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:textSize="15pt" />

        </LinearLayout>

        <android.support.v7.widget.Toolbar
            android:id="@+id/fProfilToolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin"
            app:layout_scrollFlags="scroll|enterAlways" />

    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

<FrameLayout
    android:id="@+id/fProfilContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

Answer 1

I have tried these, still not working. better solution is show and hide the CollapsingToolbar and set the AppBarLayout params dynamically.

Do this when ever you show/hide the CollapsingToolbarLayout

mAppBar.setLayoutParams(**new CoordinatorLayout.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.WRAP_CONTENT)**);

I was able to solve this by moving everything from CollapsingToolbarLayout (CTL) into Toolbar, making Toolbar the only desdendant of CTL. Then I set the CTL's height to wrap_content and in the code I used toolbar.setVisibility(View.GONE). Note that you might want to change the layout inside Toolbar, add some wrapper around its childs, like RelativeLayout or something else.

Your problem is caused by this line

    app:layout_behavior="@string/appbar_scrolling_view_behavior"

You will have to set it programatically on CoordinatorLayout not the actual container fragment that has that field.

Here is how

    mContainer = (FrameLayout) findViewById(R.id.main_content_container);

    CoordinatorLayout.LayoutParams params =
            (CoordinatorLayout.LayoutParams) mContainer.getLayoutParams();
    params.setBehavior(null);

    mContainer.requestLayout();

If you want to make it scrolling again

   params.setBehavior(new AppBarLayout.ScrollingViewBehavior());

Try to set AppBarLayout's height to zero

AppBarLayout appBar=(AppBarLayout)findViewById(R.id.fProfilAppBar);
LinearLayout.LayoutParams params=appBar.getLayoutParams();
params.height=0;
appBar.setLayoutParams(params);
