android – Coordinator layout, activity below toolbar

Posted by: admin May 14, 2020 Leave a comment

Questions:

I have an app with a coordinator layout that uses sliding tabs and a view pager in a coordinator layout. I am trying to place an activity (list) below the toolbar. I have tried a number of different things but always the list overlaps the toolbar.

Layout

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:fitsSystemWindows="true"
    tools:context=".MainActivity">

    <LinearLayout 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="wrap_content"
        android:orientation="vertical" >

            android:layout_weight="1">
        </android.support.v4.view.ViewPager>

    </LinearLayout>

    <FrameLayout android:layout_width="match_parent" android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" android:id="@+id/frameLayout">

        <include layout="@layout/activity_password_list" />

    </FrameLayout>

    <android.support.design.widget.FloatingActionButton android:id="@+id/fabNew"

        app:layout_anchor="@+id/pager"
        app:layout_anchorGravity="bottom|right|end"/>

How to&Answers:

Just add app:layout_behavior="@string/appbar_scrolling_view_behavior" to the layout that needs to be under the toolbar

        app:layout_anchor="@+id/pager"
        app:layout_anchorGravity="bottom|right|end"/>

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

I removed linearLayout and replace it with appBarLayout also , added android:layout_below in your Framelayout

good luck

Answer:

You could replace the CoordinatorLayout with a LinearLayout (with android:orientation=”vertical”).

<RelativeLayout>
    <LinearLayout> (replaces the coordinator layout>
        <AppBarLayout/>
        <FrameLayout/>
    </LinearLayout>
    <FloatingActionButton/>
</RelativeLayout>
