Using CoordinatorLayout in fragments with ActionBar in Activity

Question

I have problem using Android Design Support Library. I would like to use CoordinatorLayout inside fragment for FAB and ActionBar animations while scroll, but I having ActionBar in activity layout and my CardGridStaggeredView and FAB in fragment.

activity layout:

<?xml version="1.0" encoding="utf-8"?>

    </FrameLayout>
</RelativeLayout>

I tried to use CoordinatorLayout in Activity and Fragment, but it didn't work. Is any way to use CoordinatorLayout with ActionBar in Activity and other views in fragment?

Answer 1

here is my solution, the activity layout:

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:id="@+id/content_area"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toTopOf="@+id/main_bottom_layout">

        <com.google.android.material.appbar.AppBarLayout
            android:id="@+id/title_bar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <com.funvideo.videoinspector.photopick.ui.widget.TitleView
                android:id="@+id/title_view"
                android:layout_width="match_parent"
                android:layout_height="@dimen/dimen_title_bar_height"
                android:background="@color/simple_title_bg_default_color"
                app:layout_scrollFlags="scroll|enterAlways" />

        </com.google.android.material.appbar.AppBarLayout>

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

    </androidx.coordinatorlayout.widget.CoordinatorLayout>

    <LinearLayout
        android:id="@+id/main_bottom_layout"
        android:layout_width="match_parent"
        android:layout_height="@dimen/dimen_title_bar_height"
        android:background="@color/simple_title_bg_default_color"
        android:orientation="horizontal"
        android:visibility="gone"
        tools:visibility="visible"
        app:layout_constraintBottom_toBottomOf="parent">

        <TextView
            android:id="@+id/txt_preview"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_marginStart="12dp"
            android:text="预览"
            android:textColor="@color/social_color_4"
            android:textSize="16sp" />

    </LinearLayout>

    <LinearLayout
        android:id="@+id/album_list_root"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:orientation="vertical"
        android:layout_marginTop="@dimen/dimen_title_bar_height"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <com.funvideo.videoinspector.photopick.ui.widget.AlbumListView
            android:id="@+id/album_list_view"
            android:layout_width="match_parent"
            android:layout_height="500dp"
            android:background="@color/album_list_bg"
            tools:visibility="visible"
            android:visibility="gone" />

        <View
            android:id="@+id/album_outside"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:background="#99000000"
            android:visibility="gone" />

    </LinearLayout>

</androidx.constraintlayout.widget.ConstraintLayout>

the main_container is the place where I append my fragment in my activity:

val fragment = YImageMainFragment.newInstance(album)
        supportFragmentManager
            .beginTransaction()
            .replace(R.id.main_container, fragment, YImageMainFragment.TAG)
            .commitAllowingStateLoss()

and the layout of fragment is:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/main_recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <FrameLayout
        android:id="@+id/lot_empty_resources"
        android:layout_width="250dp"
        android:layout_height="wrap_content"
        android:background="@drawable/tips_item_bg"
        tools:visibility="visible"
        android:visibility="gone"
        android:layout_gravity="center"
        android:padding="20dp">

        <LinearLayout
            android:id="@+id/lot_go_filechoose"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:visibility="gone"
            android:gravity="center_horizontal"
            android:orientation="vertical">

            <TextView
                android:id="@+id/txv_file_choose"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:ellipsize="end"
                android:text="还是无法解决？可尝试使用文件浏览方式选取照片或视频～"
                android:textColor="@color/color_t1"
                android:textSize="13sp" />

            <Button
                android:id="@+id/btn_go_file_choose"
                android:layout_width="162dp"
                android:layout_height="36dp"
                android:layout_marginTop="16dp"
                android:background="@drawable/yellow_button_selector"
                style="@style/LegacyButton"
                android:textColor="@color/tip_pop_txt_color"
                android:textSize="13sp"
                android:text="去选取"/>

        </LinearLayout>

    </FrameLayout>

</FrameLayout>

not extra code needed, it run as my expected, this could be the versions, below are mine:

appcompatVersion=1.3.1
recyclerviewVersion=1.2.1
com.google.android.material:material:1.4.0

I have Activity with DrawerLayout and Fragments with CoordinatorLayout working just fine (pay attention where fitsSystemWindows attributes are set)

here is activity layout:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/main_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        android:background="@color/color_primary" />

    <android.support.design.widget.NavigationView
        android:id="@+id/menu_container"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <!-- Listview to display slider menu -->
            <ListView
                android:id="@+id/list_slidermenu"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@color/bm_white"
                android:choiceMode="singleChoice"
                android:listSelector="@drawable/list_selector"
                android:dividerHeight="0dp"
                android:divider="@null" />
            <!-- Картинки - fb, vk, twitter  -->

        </LinearLayout>

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