AppbarLayout with Toolbar, Navigation Drawer, and tabs

AppbarLayout with Toolbar, Navigation Drawer, and tabs - java

I'm developing an app that has a Main Activity and a Navigation Drawer to switch between different fragments inside the Main Activity.
One of the fragments contains a tab layout.
My layouts are a mess and they don't behave or perform properly.
Here is my XML:
Main:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

I want to use Coordinator Layout in my Main layout, and use AppBarLayout to wrap the Toolbar, although I don't know how to use them.
If someone could please help me organize my layout properly, with some explanations of how this works and what I am doing wrong, I would appreciate it very very much.
Thanks!

Firstly create an activity layout which contains Navigation Drawer and ToolBar
<android.support.v4.widget.DrawerLayout 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:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
android:background="#drawable/ab_bg2"
android:fitsSystemWindows="true"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleTextAppearance="#style/Base.TextAppearance.AppCompat.Subhead"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:expandedTitleMarginBottom="40dp">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:contentInsetStart="0dp"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="5dp"
android:layout_marginRight="3dp"
android:layout_marginTop="5dp"
android:background="#drawable/linlayoutshape_shadow"
android:tag="#string/layout_default"/>
</android.support.design.widget.CoordinatorLayout>
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="250dp"
android:layout_height="match_parent"
android:layout_gravity="right"
android:background="#color/Drawer_bg"
android:choiceMode="singleChoice"
android:divider="#color/Drawer_bg"
android:dividerHeight="10dp"
android:listSelector="#drawable/list_selector"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="10dp" />
Now create a Fragment which will show your Tab layout
<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="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<com.utils.PagerSlidingTabStrip
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="45dp"
android:background="#drawable/background_tab"
app:pstsShouldExpand="true" />
<com.utils.CustomViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/linHeader"
android:background="#drawable/background_tab"
tools:context=".TestBoardActivity" />
</RelativeLayout>

How to prevent bottom navigation from hiding when scrolling a CoordinatorLayout

I added a ListView with a collapsing toolbar at the top and bottom navigation at the bottom.
My problem is that the bottom navigation keeps hiding when scrolling up. I want it to stay visible.
I enabled nested scrolling programmatically. I tried many solutions, none of them worked.
This is my problem and my XML at the bottom:
This my main.xml

use a ConstraintLayout as a Root ViewGroup, and wrap in it the CoordinatorLayout, and the BottomNavigation
Then you can need to add some padding at the end of the ListView

SwipeRefreshLayout Scrolling Issues with AppBarLayout Overlap or Overlay

I have set up a AppBarLayout with a SwipeRefreshLayout and all works great except when I add app:behavior_overlapTop="200dp" to the layout. I am able to swipe down to refresh everywhere except for where the SwipeRefreshLayout overlaps the AppBarLayout. Image of layout. The yellow in the image indicates the area where I can't swipe down on. Here is my code for reference.

Always used linear layout for continuous Views and use Framelayout or Relative Layout when you what to show something position like right or bottom.

Add ScrollView after CollapsingToolBar not working

In my CountryActivityInfo.java I have a collapsing toolbar with both width and height set to match-parent so it can occupy the whole phone screen. When I scroll up the toolbar gets a fixed 200dp height.
Right now, it looks like this:
I want to display, in that white screen that appears when the toolbar is collapsed, a vertical scroll view with a text view inside. How can I do that? I've tried this way:
<android.support.design.widget.AppBarLayout
android:id="#+id/testeparainfo"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/actionBarDivider">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/backgroundcollapsedtoolbarinfo"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="exitUntilCollapsed|scroll">
<ImageView
android:id="#+id/imgCountryInfoFoto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop" />
<ImageView
android:id="#+id/imgCountryInfoEscuro"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:background="#drawable/background_pais_info"
android:scaleType="centerInside" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbaridinfo"
android:layout_width="match_parent"
android:layout_height="200dp"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
<TextView
android:id="#+id/txtNomePaisInfo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginStart="30dp"
android:layout_marginTop="520dp"
android:paddingBottom="10dp"
android:text="TextView"
android:textColor="#android:color/background_light"
android:textSize="35sp"
app:layout_anchor="#+id/testeparainfo"
app:layout_anchorGravity="left|bottom" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<ScrollView
android:layout_width="match_parent"
android:layout_gravity="bottom"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/txtInfoPais"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignStart="#+id/btnArrowBackWhite"
android:layout_marginBottom="111dp"
android:text="TextView"
android:textColor="#android:color/background_light"
android:textSize="15sp"
android:visibility="invisible"
app:layout_anchor="#+id/imgCountryInfoFoto"
app:layout_anchorGravity="bottom|center" />
</LinearLayout>
</ScrollView>
But, when I do this, the text view gets inside the collapsing toolbar and gets collapsed with the toolbar.
By the way, all the XML is wrapped up in a Coordinator Layout!!!

Change the root to CoordinatorLayout
<?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">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
android:fitsSystemWindows="true"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_scrolling" />
</android.support.design.widget.CoordinatorLayout>
and then in content_scrolling.xml use NestedScrollView and app:layout_behavior="#string/appbar_scrolling_view_behavior" use this property for proper behaviour.
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:tools="http://schemas.android.com/tools"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
...
</android.support.v4.widget.NestedScrollView>

Add app:layout_behavior="#string/appbar_scrolling_view_behavior" inside your ScrollView.

Replace this code
you have to add app:layout_behavior="#string/appbar_scrolling_view_behavior" in your ScrollView.
<ScrollView
android:layout_width="match_parent"
android:layout_gravity="bottom"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/txtInfoPais"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignStart="#+id/btnArrowBackWhite"
android:layout_marginBottom="111dp"
android:text="TextView"
android:textColor="#android:color/background_light"
android:textSize="15sp"
android:visibility="invisible"
app:layout_anchor="#+id/imgCountryInfoFoto"
app:layout_anchorGravity="bottom|center" />
</LinearLayout>
</ScrollView>

Fragment going over ActionBar in ViewPager

I am using viewpager to show different fragments but in this one of fragment replaces the actionbar. Till now I have found that it is because of edittext which I am using for searching items. When I remove edittext from this it works fine.
The main activity layout is a CoordinatorLayout, containing the typical AppBarLayout and then a ViewPager and it is filling whole screen.
fragment_gst_rates.xml:

do you tried with the linear layout at the root there try change with android:layout_height="wrap_content" .
