Develop Reference

ViewPager extends over the bottom of the screen

I'm new to Android development and I'm facing the following issue.
This is the layout of my main activity:
<?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.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_main"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:tabIndicatorColor="#color/white"
app:tabTextColor="#color/selected_text"
app:tabSelectedTextColor="#color/white"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/main_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
For each tab in the ViewPager I have a fragment, and this is the layout of one of them
<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"
android:orientation="vertical"
android:background="#color/colorPrimary"
android:id="#+id/linear_layout"
tools:context=".fragments.Reviews">
<RatingBar
android:id="#+id/review_totalRating"
style="?android:attr/ratingBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize=".5"
android:isIndicator="true"
android:progressTint="#color/golden"
android:layout_gravity="center"
android:paddingTop="10dp"
android:paddingBottom="5dp" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#android:color/transparent"
android:dividerHeight="8dp"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:id="#+id/listView_reviews" />
</LinearLayout>
Then I populate my ListView with items whose layout is defined in another xml file. My problem is with the ViewPager layout_height: it is now set to match_parent, but the element extends over the bottom of the screen, with the result that the last element of the ListView is covered by the navigation buttons.
This is what I see in the design editor
ViewPager overflow
How can I make the element stop before the navigation buttons?

I faced this issue too. It's because of AppBarLayout behavior in CoordinatorLayout. By default when you create a project from a template it will set up layout with hiding Toolbar. You can run your example and check it - just swipe toolbar up and it will hide and ViewPager will move up and then correctly sticks to the bottom of the screen.
It's not a solution for some cases so you can disable this behavior by removing app:layout_scrollFlags attribute from your Toolbar. After this, the toolbar will become unhideable and the ViewPager will calculate own height correctly.

I solved using a LinearLayout as the only child of the CoordinatorLayout, so everything else becomes a children of the LinearLayout. It seems to me to be just a simple workaround, not a final solution, but now it works. This is now the layout of my main activity:
<?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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_main"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:tabIndicatorColor="#color/orange_050"
app:tabSelectedTextColor="#color/orange_050"
app:tabTextColor="#color/orange_050"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/main_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</LinearLayout>

How to get a border at the bottom of my toolbar?

I want to add a gray border at the bottom of my white toolbar so that it's distinctly separated from the main content. I'm setting up my toolbar like this:
<?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"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical"
android:id="#+id/pick_root_layout">
<android.support.v7.widget.Toolbar
android:id="#+id/pick_toolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
app:theme="#style/Toolbar.White"
android:background="#color/white">
</android.support.v7.widget.Toolbar>
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/conversation_list">
</ListView>
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>
I need to add a small gray line at the bottom of the toolbar that also scrolls with it when I move. How can I do this? I'd like to avoid making a custom layout if possible.

If you are trying to add a drop shadow type effect that will stay attached to the toolbar an easy way to get this is to wrap your SwipeRefreshLayout with a FrameLayout and place a foreground on the FrameLayout.
<?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"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical"
android:id="#+id/pick_root_layout">
<android.support.v7.widget.Toolbar
android:id="#+id/pick_toolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
app:theme="#style/Toolbar.White"
android:background="#color/white"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:foreground="#drawable/bottom_shadow">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/conversation_list" />
</android.support.v4.widget.SwipeRefreshLayout>
</FrameLayout>
</LinearLayout>
Shadow 9 patch ->

set background for activity containing AppbBarLayout

I am trying to use androids CoordinatorLayout and FrameLayout. What I want to have is a
toolbar
LinearLayout showing some info
tablayout
listviews
when the listviews are scrolled the toolbar and the LinearLayouts should scrollup and hide and the tabs should go at the top.
I have a layout of the type:
<android.support.v4.widget.DrawerLayout
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_width="match_parent">
<android.support.design.widget.AppBarLayout

android:text="Gamercard content"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="More Gamercard content"
/>
</LinearLayout>
</LinearLayout>
<-- stuff I dont want to hide on scrolling -->
<android.support.design.widget.TabLayout
android:id="#+id/tabLayout"
android:scrollbars="horizontal"
android:layout_below="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.design.widget.AppBarLayout>
<!-- My Scrollable View -->
<include layout="#layout/nested_scrolling_container_view"/>
</android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.DrawerLayout>
What I want to do is have a picture as the background for the entire activity, but what I see is that the AppBarLayout part is always dark. Please help.

I could do it programmatically by setting the backgroundColor in code to Color.TRANSPARENT.
appbar.setBackgroundColor(Color.TRANSPARENT);

How to set Custom ActionBar to fixed top position inside ScrollView layout?

How do I set this action bar in a way even when scroll the long data screen it keeps visible on the top of the screen?
toolbar.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
Guys please see my update:
I tried everything but it seems that next component after actionBar is not being set after actionBar but behind it:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="#drawable/background_telas"
android:orientation="vertical" >
<include layout="#layout/toolbar" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
</ScrollView>
</LinearLayout>
<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/actionBar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/actionBarBackgroundColor"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp" >
</android.support.v7.widget.Toolbar>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#A0A09F" />
Project (eclipse):
Screen stopped:
Screen scrolled up:
Java:
Toolbar actionBar = (Toolbar) findViewById(R.id.actionBar);
actionBar.setTitle("ProTaxi Passageiro");
actionBar.setSubtitle("Cadastro");
actionBar.setTitleTextColor(Color.parseColor("#846A1A"));
setSupportActionBar(actionBar);

If you don't want the Toolbar to scroll with the content, then you have to put it outside the ScrollView.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/toolbar" />
<ScollView
...>
you content here..
</ScollView>
</LinearLayout>

You can also set the layout_scrollFlags to enterAlways to get rid of the toolbar scrolling.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>

I had a similar problem with the layout behind the toolbar, setting fixed height to the Toolbar helped me, try android:layout_height="?attr/actionBarSize". Also use the layout #Floern adviced you.

To fix the layout above the bar, try doing the following. Wrap the whole activity in a relative layout. Then give an id to the Top Action Bar Relative layout. Afterwards on your scroll view, add this line layout_below/#id/top_profile_bar to have the layout scroll below the bar.
<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">
<!--Top Action Bar-->
<RelativeLayout
android:id="#+id/topprofilebar"
android:layout_width="match_parent"
android:layout_height="50dp">
<include layout="#layout/top_actions_bar" />
</RelativeLayout>
<!--Add a layout_below/#id/top_profile_bar to have it below the bar-->
<ScrollView
android:layout_below="#id/topprofilebar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--Some Content-->
</ScrollView>
then in your top_actions_bar.xml add app:layout_scrollFlags="enterAlways" to the tool bar.
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<androidx.appcompat.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:id="#+id/profileToolBar"
app:layout_scrollFlags="enterAlways"
android:background="#drawable/bg_white_grey_border_bottom">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/ivBack"
android:layout_width="wrap_content"
android:layout_height="match_parent"/>
<TextView
android:layout_toRightOf="#+id/ivBack"
android:id="#+id/top_actions_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:textSize="20sp"
android:textColor="#color/colorBlack"
android:layout_marginLeft="15dp"
android:text="Scoper Settings"
/>
</RelativeLayout>
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
Hope this helps!

Android Parent View: How do I reduce by the size of the Toolbar?

I've set up a new android Toolbar with:
android:layout_height="?attr/actionBarSize"
The toolbar appears correctly at the top of the screen. The problem I'm having is that the top of the background image for the remainder of the app screen is being covered over by toolbar. I need to reduce the height of the container that holds the background image by the height of the toolbar in my layout file but am not having any luck.
The toolbar is showing correctly. It has an image as a background.
Here is the main.xml file:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/big_wave"
tools:context=".MainActivity" >
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:background="#drawable/actionbar_skypic" />
</RelativeLayout>

You can adjust the height of the image yourself, can't you? Or you can set the tool baar background as translucent or transparent.
toolbar.getBackground().setAlpha(0);

You can use android:layout_below property
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimaryDark" />
<com.example.sample.SlidingTabLayout
android:id="#+id/sliding_tabs"
android:background="?attr/colorPrimaryDark"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#android:color/white" />
</LinearLayout>
Here is the output.
You can see below toolbar there is sliding layout tabs
