android – Menu options not showing on Collapsing Toolbar

Posted by: admin June 15, 2020 Leave a comment

Questions:

I am trying to implement a Collapsing Toolbar Layout with menu options but whenever I set the image view source in the below code, the image covers the menu and the back button. The options are there as I can click on them, they are just hidden by the image. Does anyone know how to fix this?

XML Layout

    <android.support.design.widget.AppBarLayout android:id="@+id/app_bar"
        android:layout_width="match_parent" android:layout_height="@dimen/app_bar_height"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.CollapsingToolbarLayout android:id="@+id/toolbar_layout"
            android:layout_width="match_parent" android:layout_height="match_parent"
            android:fitsSystemWindows="true" app:contentScrim="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|exitUntilCollapsed" app:toolbarId="@+id/toolbar">

            <android.support.v7.widget.Toolbar android:id="@+id/detail_toolbar"
                android:layout_width="match_parent" android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                android:fitsSystemWindows="true"/>

            <ImageView
                android:src="@drawable/background"
                app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:scaleType="centerCrop"
                app:layout_collapseMode="parallax"
                android:minHeight="100dp"
                android:fitsSystemWindows="true"/>

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

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

Answer:

From own experience this tells me this you probably have forgotten to add the following lines to the activity:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

setSupportActionBar(toolbar);

Answer:

Try adding collapseMode attributes to the Toolbar…like this. It pins the toolbar.

<android.support.v7.widget.Toolbar


    app:layout_collapseMode="pin" />
