I want to show the same elevation effect on my toobar on a KitKat device as seen on a Lollipop device. Below are screenshots for both the KitKat and Lollipop devices. I have referred to this link but my problem is not solved yet.
Lollipop Device:
Kitkat Device:

As mentioned, elevation is not available below lollipop devices but, there are few alternative ways for doing that.
I've personally tried everything and none worked but could managed it by adding a layout-v19 folder in res folder of project. So, it will be a specific API-19 layout. There, you can add a view under Toolbar-AppbarLayout (depends on your design) with 4dp height or any other methods as following links:
https://github.com/vipulasri/Toolbar-Elevation-Pre-Lollipop
And this: https://mobikul.com/show-shadow-toolbar-api-21/
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include
android:id="#+id/toolbar"
layout="#layout/toolbar" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Place Your Layout Here -->
<View
android:id="#+id/shadow_view"
android:layout_width="match_parent"
android:layout_height="5dp"
android:background="#drawable/dropshadow" />
</FrameLayout>
</LinearLayout>
dropshadow.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#android:color/transparent"
android:endColor="#60555555"
android:angle="90"/>
</shape>
And in java-kotlin side, check if it is API-19, then inflate the layout there:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
v = inflator.inflate(R.layout.item_showdetail_asset_kitkat, this);
} else {
v = inflator.inflate(R.layout.item_showdetail_asset, this);
}
Hope this helps.

First, I want to make a tablayout fragment, and in fragment One i want to add recycler view , but the top of recyclerview getting cut by view pagger or tab layout at the top.

I already tried code below, or change the orientation. But its still going wrong, please someone help me
This is because you are using CoordinatorLayout with ListView. You can change your implementation to RecyclerView to achieve correct scroll.
or If you are tagetting above 5.0, you can use the following piece of code
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
listView.setNestedScrollingEnabled(true);}
I think CoordinatorLayout only works with the children of NestedScrollingChild.
Try replacing the ContraintLayout with the CoordinatorLayout in your activity_tablayout.xml
Check this out for the source code with an example.
Also check out this video
https://www.youtube.com/watch?v=DyyNxJtYTBc
Hope this helps.
You convert your CoordinatorLayout to LinearLayout and set orientation "vertical", like this. I think this will solve your issue.

My Webview is implemented in Tab Fragment. I would like to scroll web view to the bottom in fragment. Now i can't scroll down the webview in fragment. I'm using android studio to develop it. Below is my code:
Fragment XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout

android:layout_width="match_parent"

Alright try using RelativeLayout it will be shown full. You are facing this problem due to constraintLayout:
<?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"
android:paddingBottom= "5dp">
<WebView
android:id="#+id/webview"
android:layout_width="371dp"
android:layout_height="516dp"
tools:layout_editor_absoluteX="-12dp"
tools:layout_editor_absoluteY="-3dp" />
</RelativeLayout >
#Umair answer pointed me int the right direction but it missed a point. I did not have to change to relative layout to fix it, my webview was throwing a warning, that it is not correctly constrained (see the red underline)
After I changed width and height to
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
tools:layout_editor_absoluteY="1dp" />
the problem got fixed right away. Now it is possible that this problem shows up only in fragments but this is one way to fix it.
Is There anyway to prevent repeating code in android layout xml?
for example I have layout that has a TabLayout I want to show Tablayout in in
Right to Left Direction so I use android:layoutDirection="rtl"
But as you know this is not supported under API 17 so I have to override my Code for API 17. But each time I want to modify my layout I have to repeat same actions in both xml file is there any easy and better way?
Layout for API 17:
<?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:background="#color/main_background_color">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center">
<android.support.design.widget.TabLayout
android:id="#+id/promotion_type_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable"
app:tabGravity="center"
app:tabTextAppearance="#style/AppTabTextAppearance"
app:tabIndicatorColor="#color/cardview_light_background"
app:tabTextColor="#FFF"
android:layoutDirection="rtl"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/promotion_view_pager"
android:background="#color/main_background_color" />
</android.support.design.widget.CoordinatorLayout>
and Layout for Under API 17:
<?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="wrap_content"
app:tabMode="scrollable"

android:layout_height="wrap_content"

You could export the layouts in their own file and <include/> them in the Activity/Fragment layout e.g.
<include layout="#layout/base_table" />
See the developer guide Re-using Layouts with include
CollapsingToolbarLayout from appcompat shows shadow in collapsed state, but when expanded (or expanding in process) shadow disappear

I had the same issue and found a solution:
First you have to update to the latest Support Library (I use 24.1.0)
Then apply the stateListAnimator to your AppBarLayout:
example:
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="320dp"
android:stateListAnimator="#drawable/appbar_always_elevated"
android:fitsSystemWindows="true">
and use this xml as animator:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<objectAnimator android:propertyName="elevation"
android:valueTo="8dp"
android:valueType="floatType"
android:duration="1"/>
</item>
</selector>
You can find official stateListAnimator for AppBarLayout here
1. Put this appbar_elevation.xml into resources directory named animator-v21
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
tools:ignore="PrivateResource">
<item>
<objectAnimator
android:propertyName="elevation"
android:valueTo="#dimen/design_appbar_elevation"
android:valueType="floatType" />
</item>
</selector>
2. On AppBarLayout set android:stateListAnimator="#animator/appbar_elevation"
Just use
app:liftOnScroll="false"
on the AppBarLayout
I'm working on a tab activity in my app, but it seems that the tabs are using the wrong height (thinking the layout is about half an inch taller than it is on any device) and as a result any vertical centering is off on the low side, and my scrollviews are messed up because the screen won't scroll far enough down to see the bottom of the view. I have tried tinkering with the layout_height on any relevant class I can think of and hiding the tabs, but nothing helps and I cant find this problem anywhere else. I generated the default template for a TabLayout activity in Android Studio 1.4.

On activity_main you can create a RelativeLayout. Put your ViewPager and AppBarLayout inside RelativeLayout and set your ViewPager like this:
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/appbar"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:layout_scrollFlags="scroll|enterAlways">
</android.support.v7.widget.Toolbar>
you have to wrap content for the widget.toolbar
