I have an activity with a title, a fragment with a recyclerview full of cards and a bottom navigaton bar.
I cannot manage to show all 3 together without problems, the closest I have been is showing all 3, but with the bar taking space from the cards space.
Right now this is the XML which I thought should be working:
<LinearLayout 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:orientation="vertical"
tools:context=".habits.HabitsActivity">
<ImageView
android:id="@+id/imageView"
android:layout_width="313dp"
android:layout_height="166dp"
android:layout_gravity="center_horizontal"
app:srcCompat="@drawable/goodreasons" />
<android.support.design.widget.CoordinatorLayout
android:id="@+id/coordinatorLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/contentFrame"
android:layout_width="match_parent"
android:layout_height="match_parent"></FrameLayout>
</android.support.design.widget.CoordinatorLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom">
<com.aurelhubert.ahbottomnavigation.AHBottomNavigation
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</FrameLayout>
</LinearLayout>
But this gives this output:
This is the xml of the fragment, in case you think it is relevant too.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:layout_gravity="center"
android:orientation="vertical"
android:padding="5dp"
>
<android.support.v7.widget.RecyclerView
android:id="@+id/rv_list"
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0"
android:layout_gravity="center"
/>
</LinearLayout>
Here's your layout, stripped down:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="313dp"
android:layout_height="166dp"/>
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Your problem is that the CoordinatorLayout
has a match_parent
height, so it will take up all of the space that the ImageView
doesn't. That leaves no space at all for the FrameLayout
, so you won't be able to see anything inside of it.
Probably the best thing to do would be to use layout_weight
on the CoordinatorLayout
to make it take up as much space as it can while still leaving room for other views. That would look something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="313dp"
android:layout_height="166dp"/>
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
The only changes I made were to set the CoordinatorLayout's height to 0dp
and the FrameLayout's height to wrap_content
, and to add the weight attribute to the CoordinatorLayout.
