How do I use parallax to scroll through my content? - android

I have some issues with parallax for android, where I currently have an image on top (with text content in the center) and a button on the top right.
Now as I scroll, I want the text and button to remain fixed on screen. As I scroll past the appbar (toolbar), the toolbar should be fixed to the top and the button should be on top right of it, fixed to it , while the rest of the content stays scrollable.
Here's my code (without parallax), any clue how i can achieve this ?

As you can see from the above layout. I want to add an image (and add the my_button on top right of that image) that is above the toolbar and scrolls off the screen as you scroll up while my button stays in its place until the toolbar gets on top ,after which the toolbar is affixed to the top as you scroll further up, unless you scroll down and the image is visible again and the button is no more fixed.
Please let me know if this is confusing,I will try to explain it better with diagrams if possible.
Any examples will be helpful! thanks!

Place button on the top right side of AppBarOverlay

I'm trying to place a button to the right side of AppBarOverlay, I have got it to appear it to the right, but it's below AppBarOverlay text. Below is the image of what it looks like now.
Instead I want the "clear" button to appear where I have drawn the red circle

AppBarLayout is a vertical LinearLayout. So you can't achieve this with AppBarLayout.
For reference https://developer.android.com/reference/com/google/android/material/appbar/AppBarLayout
You can achieve your desired output by using Toolbar

Align TabLayout with collapsing toolbar

I have a collapsing toolbar and a tablayout in my layout file.
The tab layout only appears when the toolbar is fully collapsed.
My problem is, the tab layout appears like this:

Changing from one view to another view onScroll

I am working a project. I have a a layout with a view at top and a Scrollview at the bottom of the view. Initially the layout will look like this.
After I scroll up the bottom layout. The view should smoothly change the the below view. And if I scroll down the view should come back to its previous layout.
As you can see there is a change in the position and size of the textviews. How can I achieve this ?
Here is the layout:

You can use the Collapsing Toolbar Layout
Example Here and here
Edit: some piece of code
<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/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="?attr/colorPrimary">
<ImageView
android:id="#+id/expandedImage"
android:layout_width="match_parent"
android:layout_height="200dp"
android:src="#drawable/beach_scene"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.7"
/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" >
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/sample_string"/>
</android.support.v4.widget.NestedScrollView>

Using a Collapse Tool Bar as João said, your code should be like this
and getting my answer as base from here
<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:clipToPadding="false">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="210dp"
android:background="#color/WHITE">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:collapsedTitleTextAppearance="#style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse"
app:expandedTitleMarginStart="72dp"
app:expandedTitleTextAppearance="#style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<Your Content>
<android.support.v7.widget.Toolbar
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="40dp"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include
layout="#layout/homescreen_scrollview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/layout_header_profile"
android:layout_marginTop="15dp" />
On <Your Content> is the place where you should put your string.
Sorry that I can't help more. Your Cody is a little messy and really hard to understand.
Maybe if you edit leaving only the important codes will help.
But maybe this library can help you.

Custom views in toolbar like Airbnb explore screen

I want to add multiple input fields in top bar area of application (toolbar) for search purposes of my app. I see that Airbnb does that at its best! I have tried various scenarios using AppBarLayout in CoordinatorLayout but it all failed. Is it possible to get the same or similar effect? If yes, how do we do that?
Here are the screenshots when I swipe down the top bar:

Yes it is possible to create using appbar layout, I have tried same task, Finally i have figured-out in this way, I guess below code is helpful for you

You can see I use a Toolbar with visibility = invisible to force my layout to stay partialy visible. I am not really proud of that trick but I failed to find an other solution.
Once you have your layout it's just a matter of animation depending on the progress of the offset.
If you succeed, I would be happy to see your code because I'm not really happy with mine.
I hope it can help you.

Content of coordinator layout not gets scrolled when scrolling in appbar layout

I'm trying to implement new android design support library. I have a view pager inside appbar layout and a tab layout below it. Also I need to stick my toolbar and tab header layout on top while scrolling. When I try to scroll the content by scrolling in appbar layout, it didn't gets scrolled. But when I scrolled in content of tablayout, the whole content will gets scrolled. Here is my xml:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/outer_coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffb4b4b4"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar

android:layout_width="match_parent"
android:layout_height="wrap_content"

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"

To answer your question, first you need to know how the nest scroll works.
The nest scroll behavior implemented by AppBarLayout is mainly based the NestScrolling system. The system only start nest scroll event dispatching when the touch event start from the NestScrollingChild which is the RecyclerView inside the ViewPager.
Therefore, if you want to start nest scroll from the AppbarLayout, there is no easy way to just modify the xml to achieve it.
