I've tried to use the floatingactionbutton element but it doesn't float in UI layout, the floating button occupies part of the layout and isn't over the component, in my case is a viewpager,
button doesn't float
this is my layout:
<LinearLayout 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"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.frases.frases.FraseMain"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/appbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" >
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"/>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#android:color/white" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:src="#android:drawable/ic_dialog_email" />
</LinearLayout>
It's because you are using LinearLayout as the root layout. You need FrameLayout to stack elements over one another, and FAB needs to be the last child node because it needs to stay on top of every other views.
<FrameLayout>
<LinearLayout>
...
</LinearLayout>
<!-- FAB be the last node inside FrameLayout here -->
<android.support.design.widget.FloatingActionButton />
</FrameLayout>
I don't think you have to use coordinator layout, you can simply use floating button with below code as well.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/dashboard_bg"
xmlns:app="http://schemas.android.com/apk/res-auto">
<!-- here you can have your viewpager -->
<android.support.design.widget.FloatingActionButton
android:id="#+id/dashboardShowActionsFab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:elevation="4dp"
app:fabSize="normal"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginRight="26dp"
android:layout_marginBottom="16dp" />
</RelativeLayout>
Hope this helps.
use CoordinatorLayout like below:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_margin="16dp"

Hey i want in my android app that the recyclerlistview and the floatingActionButton not cut the toolbar. Here is my Layout:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
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="match_parent">
<include
layout="#layout/toolbar_task_layout">
</include>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView_task"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
app:layout_anchor="#id/recyclerView_task">
</android.support.v7.widget.RecyclerView>
<android.support.design.widget.FloatingActionButton
android:id="#+id/floatingActionButton_task_openDialog_"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_margin="16dp"
android:src="#drawable/ic_add_black_36dp"
app:layout_anchor="#id/recyclerView_task"
android:clickable="true"
app:fabSize="normal"
app:layout_anchorGravity="bottom|right|end"/>
</android.support.design.widget.CoordinatorLayout>
Here you can see the problem:
Update:
Here is the toolbar layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar 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:id="#+id/toolbar_task"
android:layout_alignParentTop="true"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0 items selected"
android:id="#+id/counter_task"
android:textSize="18dp"
android:textColor="#ffffff"
android:textStyle="bold" />
</RelativeLayout>
</android.support.v7.widget.Toolbar>
Try replacing your <include layout="#layout/toolbar_task_layout"></include>
with this:
<include layout="#layout/toolbar_task_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
EDIT: I assume you also want your FAB to be on the bottom right since this is the norm, try setting android:layout_alignParentBottom="true" and android:layout_alignParentRight="true" in your FAB and make the RecyclerViews height match_parent
try this make your toolbar android:layout_height to android:layout_height="?attr/actionBarSize"
<android.support.v7.widget.Toolbar
android:id="#+id/ac_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="exitUntilCollapsed"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" >
Use below code:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
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="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/toolbar_task_layout"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView_task"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp"
app:layout_anchor="#id/recyclerView_task"
android:layout_below="#+id/toolbar_task"/>
</RelativeLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/floatingActionButton_task_openDialog_"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_margin="16dp"
android:src="#mipmap/ic_launcher"
app:layout_anchor="#id/recyclerView_task"
android:clickable="true"
app:fabSize="normal"
app:layout_anchorGravity="bottom|right|end"/></android.support.design.widget.CoordinatorLayout>
I hope this will help.....
I have the following Xml code where I want to display the content of a fragment into FrameLayount but I don't know how to keep my button always on bottom.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_lista_preguntas"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.ingenierovagabundo.encuestafacil.GUI.ListaPreguntasActivity">
<!-- Toolbar -->
<android.support.v7.widget.Toolbar xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/appbar_nueva_pregunta"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<FrameLayout
android:id="#+id/contenedor_Pregunta"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</FrameLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp"
android:text="#string/npa_button_guardar"/>
you can use RelativeLayout insted of LinearLayout as below:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_lista_preguntas"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.ingenierovagabundo.encuestafacil.GUI.ListaPreguntasActivity">
<!-- Toolbar -->
<android.support.v7.widget.Toolbar xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/appbar_nueva_pregunta"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<FrameLayout
android:id="#+id/contenedor_Pregunta"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/btn"
android:layout_below="#+id/appbar_nueva_pregunta">
</FrameLayout>
<Button
android:id="#+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="false"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp"
android:text="#string/npa_button_guardar" />
You could add android:layout_weight="1" to your FrameLayout. This will expand the FrameLayout to fill any remaining space in the parent view. Which should result the Button to be at the bottom.
So your resulting FrameLayout will be,
<FrameLayout
android:id="#+id/contenedor_Pregunta"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1">
</FrameLayout>
For more on layout_weight follow the link
https://developer.android.com/guide/topics/ui/layout/linear.html#Weight
You use a LinearLayout as container, then the elements follow each other.
If you want to keep your button always on bottom, use a RelativeLayout with
android:layout_alignParentBottom="true".
You also need to close your container! ;)
Use this Code in activity_main.xml
<?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"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
app:backgroundTint="#color/colorOrange"
app:srcCompat="#android:drawable/ic_menu_share"
tools:ignore="VectorDrawableCompat" />
</android.support.design.widget.CoordinatorLayout>
And in content_main.xml, use this Code.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
tools:showIn="#layout/app_bar_main">
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>

This FAB is displaying in top right in layout. I want to display it on bottom right.
Can anyone help me on this?
Include your FAB layout in your parent layout giving layout_alignParentBottom property true:
<include layout="#layout/activity_dialog"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"/>
Also try to change CoordinatorLayout android:layout_height="fill_parent"
:
<android.support.design.widget.CoordinatorLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:id="#+id/coordinatorLayout"
android:orientation="vertical">
Remove the <include> tag.
Place your FAB in its place with the <anchor> tag:
app:layout_anchorGravity="bottom|right|end"
<android.support.design.widget.FloatingActionButton
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_anchorGravity="bottom|right|end"
android:clickable="true"
android:src="#drawable/cart"
android:layout_margin="20dp"
app:elevation="6dp" />
If you still aren't winning, revise your layout by referring to this: FAB in the corner.
This is my layout file.

I want to set all 3 elements vertically. But they are overlapping in current layout.
layout_below doesn't seems to work here.
How to fix the issue?
I have mentioned a snippet of layout, i guess this is something you want. check on github

can't help you with FloatingActionButton, it supposed to float , lol :)
When you create a blank Activity in android studio, this is the given 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="com.example.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
And the Relative layout (#layout/content_main) goes out of screen:
If you set a button in your relative layout, with layout_alignParentBottom the button sometimes will go out of screen. (It doesn't happen all the time, I have no idea why)
#layout/content_main
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.MainActivity"
tools:showIn="#layout/activity_main">
<Button
android:id="#+id/button"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="70dp"
android:background="#color/green"
android:textColor="#color/white"
android:text="text"
android:focusable = "true"
android:focusableInTouchMode = "true"
/>
</RelativeLayout>
Adding Padding bottom to the relative layout won't work. (As it'll only work when the button is off the screen)
I need the button to be at the bottom of the screen always. Can someone tell me how to achieve this?
Like this:
Try the following code, this will keep that button at the end without going to out of the view:
<?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="com.example.android.myapplication.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</android.support.design.widget.CoordinatorLayout>
And the Relative layout (#layout/content_main) goes out of screen:
Edit: i think that's because you've set them match_parent.try something like this:
<?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"

android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
