android: Displaying multiple images like INSIDE the Tinder-cards

How would I go about displaying multiple images the way Tinder does it: it should display the next image when I click on the right side of the image and display the previous image when I click on the left side of the image.
It should also display a little arrow to the right or left only when clicked and show somehow which picture is being displayed (with little bars like tinder or dots or something).
Is there a library for that?
EDIT:
To clarify: I already implemented the Tinder swipe-cards with the help of the Diolor/Swipecards library. What I'm suprisingly a little stuck with is implementing the image gallery INSIDE the Tinder swipecards. Only the part seen in the picture above.

There are a lot of libraries to it for you

My solution was adding two pictures of arrows, putting two layouts above them, then adding onClickListeners for the Layouts, which select the next/previous picture in the adapter to be displayed in the ImageView.

Now Issue is RecycleView is not scrolling at all . whats wrong with the code. What needs to be change .Or Suggest me anyother way to achieve this design

1) Change
android:layout_below="#+id/relativeLayout1"
to android:layout_below="#id/relativeLayout1" and change anywhere else you have layout_below or layout_above
+ is used when creating a new id. When giving an already created id we use it without +
2) You don't really need RelativeLayout with id rlRecycle. You can directly move layout_below and layout_above attributes to RecyclerView because it's already under top level RelativeLayout

I Found The Solution . i know there are lots of extra RelativeLayouts . Know I removed it . and putted rlMiniPlayer below the nested scrollview
Because I am using nestedscrolling=true . in the code . This is creating the problem
Like This :-
</android.support.v4.widget.NestedScrollView>
<RelativeLayout
android:id="#+id/rlMiniPlayer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
>
</RelativeLayout>

Android - ImageView overlay another ImageView

I would like to make an ImageView overlay another ImageView like this; only half of the circle green is overlaying the image:
I have tried using RelativeLayout and put both ImageView inside. Then I overlay the circle over the image by using android:layout_alignBottom. It did overlay the but I have no idea how to set the offset so that only half of the circle is overlaying the base image.
EDIT:
Sorry, here is my layout xml code
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="32sp" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/image_view_product"
android:layout_centerHorizontal="true"
android:background="#drawable/image_view_circle"
android:src="#drawable/ic_circle" />
</RelativeLayout>

I get lots of upvote for this answer.So i try to improve that answer. May be this is the better way to do that compare to other two, because this solution doesn't required to fix the layout or divide screen in equal part so may be this is better to do that.

Alternate way Try this
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
// this is your first layout to put the big image
// use src or backgroud image as per requirement
<LinearLayout
android:background="#color/red_error"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</LinearLayout>
// this is your bottom layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</LinearLayout>
</LinearLayout>
// This is the imageview which overlay the first LinearLayout
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/success"
android:adjustViewBounds="true"
android:layout_gravity="center"/>
</FrameLayout>
its look like this
found one more solution for that (Edit)
if your big image size is fixed height you can try this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:id="#+id/layoutTop"
android:background="#color/red_error"
android:layout_width="match_parent"
android:layout_height="200dp" >
</RelativeLayout>
<RelativeLayout
android:id="#+id/layoutBottom"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_alignParentBottom="true"
android:layout_below="#id/layoutTop" >
</RelativeLayout>
<ImageView
android:id="#+id/overlapImage"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_above="#id/layoutBottom"
android:layout_centerHorizontal="true"
android:layout_marginBottom="-20dp"
android:adjustViewBounds="true"
android:src="#drawable/testimage" />
</RelativeLayout>
Refernce :- Android: Placing ImageView on overlap between layouts
Hope this will help.Good Luck

Try out this way:
Just change layout_width and layout_height according to your need.
<?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:orientation="vertical" >
<View
android:id="#+id/viewOne"
android:layout_width="match_parent"
android:layout_height="200dp"
android:background="#126989" />
<View
android:id="#+id/viewTwo"
android:layout_width="match_parent"
android:layout_height="70dp"
android:layout_below="#+id/viewOne"
android:background="#547866" />
<View
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_alignBottom="#+id/viewTwo"
android:layout_centerHorizontal="true"
android:background="#ff7800"
android:layout_marginBottom="35dp" />
</RelativeLayout>
It will look like this:

I would recommend Constraintlayout as it gives excellent control over the positioning of individual view items. Sample based on your example below
<android.support.constraint.ConstraintLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/parentLayout">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product"/>
<View
android:layout_width="50dp"
android:layout_height="50dp"
app:layout_constraintTop_toBottomOf="#+id/image_view_product"/>
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_alignBottom="#id/image_view_product"
android:layout_centerHorizontal="true"
android:background="#drawable/circle"
android:src="#drawable/ic_add_circle_green_24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"/>
</android.support.constraint.ConstraintLayout>

Use layout_marginTop = -20dp ( Half of your image size ). It will go up.
android:layout_marginTop="-20dp"

put both the image in Relative layout
first define the image you want to put behind the green circle
than define the green circle as
android:layout_alignBottom="#+id/Image1"
Than adjust the position by giving margin to the green circle image.

I recommend you to use a framelayout with these two images.
with the refresh imageview at the bottom and the table fan at the top.
Note : As the framelayout behaves like a stack, the item at the bottom will appear at the top.
And do the set the gravity of the refresh icon to be bottom|center to make it look this way.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:src="#drawable/ic_fan"
android:scaleType="centerCrop"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
<ImageView
android:src="#drawable/ic_refresh"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:gravity="center|bottom"/>
</FrameLayout>

<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="32sp" >
<ImageView
android:id="#+id/ivBackground"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_marginTop="-20dp"
android:layout_below="#+id/ivBackground"
android:layout_centerHorizontal="true"
android:background="#drawable/image_view_circle"
android:src="#drawable/ic_circle" />
I think this should help you i have edited your code and made changes as below
- I change circle imageview height to 40dp and then i give margin top -20 dp so that image will overlay half as you need on background image.
I did not run this code so if you face any issues just let me know i hope this works well for you..

Screenshot:
activity_main.xml:
<RelativeLayout
android:id="#+id/rl_image"
android:layout_width="match_parent"
android:layout_height="200dp">
<ImageView
android:id="#+id/thumbnail"
android:layout_width="match_parent"
android:layout_height="160dp"
android:background="?attr/selectableItemBackgroundBorderless"
android:clickable="true"
android:contentDescription="null"
android:scaleType="fitXY"
android:src="#drawable/album9" />
<ImageView
android:id="#+id/imageView_round"
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:src="#drawable/user_profile" />
</RelativeLayout>

Using layout_above/layout_below does not yield expected results. Item dissapears

I have the following code:
grid_view_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical">
<RelativeLayout
android:layout_width="wrap_content"
android:gravity="center_horizontal"
android:layout_height="wrap_content">
<com.entu.artapp.utils.SquareImageView
android:id="#+id/gridItem_squareImageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:visibility="invisible"/>
<com.entu.artapp.utils.SquareImageView
android:id="#+id/gridItem_selectedColor"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:background="#e85349"
android:alpha="0.45"
android:visibility="invisible"/>
<com.entu.artapp.utils.SquareImageView
android:id="#+id/gridItem_constantGrey"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:background="#000000"
android:alpha="0.45"
android:visibility="visible"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:textColor="#FFFFFF"
android:id="#+id/gridItem_textView"
android:layout_centerInParent="true"
android:hint="AAAAAAAAA"/>
<ImageView
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_centerHorizontal="true"
android:src="#drawable/checkmark"
android:id="#+id/gridItem_selectedCheckMark"
/>
<ProgressBar
android:id="#+id/gridItem_progressBar"
style="?android:attr/progressBarStyleSmall"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_centerInParent="true"
android:visibility="visible"/>
</RelativeLayout>
Which yields this view:
I want my item to look like this:
So, I added this line in my CheckMark imageView code:
android:layout_above="#+id/"gridItem_progressBar"
And the checkMark imageview just dissapears. Same for layout_below, as shown here:
Can anyone help me in solving this problem?
Cheers!

It may help you if you use padding instead of above or below, why do you want linear layout as your parent and relative view as child it will be more easier if you have relative layout as parent. Hope this may help you.

SlidingDrawer over GoogleMap

First of all, I know the SlidingDrawer is deprecated, but I haven't found any alternative to it so I'm using it anyways :3 (If someone knows an alternative to it, please share it!)
So I have a GoogleMap in my activity (actually a fragment but it doesn't matter), and a nice SlidingDrawer in the same screen. It works fine, but when I open or close the slidingdrawer over the map, it starts behaving weird. It looks like the map want's to stay in front of the slidingdrawer. When the drawer is fully opened, then it comes back to the front and everything is ok.
Is there a workaround for this? I am getting crazy!
here is my 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"
android:id="#+id/window"
>
<fragment
android:id="#+id/hackedmap"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
<SlidingDrawer
android:id="#+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:content="#+id/drawercontent"
android:handle="#+id/drawerhandle"
android:orientation="horizontal"
>
<LinearLayout
android:id="#id/drawerhandle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:gravity="center" >
<ImageView
android:id="#+id/slidingHandle"
android:layout_width="40dp"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitEnd"
android:src="#drawable/sliding_handle" />
</LinearLayout>
<LinearLayout
android:id="#+id/drawercontent"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#DD000000"
android:gravity="center_horizontal|top"
android:orientation="vertical" >
<TextView
android:id="#+id/selectednet"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_margin="4dp"
android:text="Select a network:"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#02bceb" />
<ListView

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

</ListView>
</LinearLayout>
</SlidingDrawer>
</RelativeLayout>

Put the map inside of a relative layout. In front of the map a view with the same measure.
Example:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<include
android:layout_width="wrap_content"
android:layout_height="250dp"
android:layout_weight="1"
layout="#layout/general_map_fragment" />
<View
android:id="#+id/imageView123"
android:layout_width="match_parent"
android:layout_height="250dp"
android:background="#color/transparent" />
</RelativeLayout>
