Android How to put a FloatingActionButton in right position?

I'm trying to put a FloatingActionButton on the map.
I want to put two buttons on the "botton|right" position of the map but it doesn't work well.
This is what I can see on design and I want to make like this. But, after I upload the code to my phone, I can see those buttons are not staying there.
This is how it works on my phone. (Sorry that the picture is too big..)
This is my code.. Please take a look at it

I really appreciate your help!

When you design any screen have the Nexus 4 phone of the 4.7-inch screen. The design which you see in that screen will not change when you run on bigger phones. And use Constraint Layout instead of Linear or Relative layout because it gives you a very good result on the UI part.

Your layout is definitely overcomplicated, but may be you should do this (notice LinearLayout parent of fabs changed to ConstraintLayout):
<android.support.constraint.ConstraintLayout
android:id="#+id/linearLayoutTmap"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.FloatingActionButton
android:id="#+id/navigate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="28dp"
android:clickable="true"
app:layout_constraintBottom_toTopOf="#+id/current_location"
app:layout_constraintEnd_toEndOf="parent"
app:srcCompat="#drawable/location" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/current_location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="28dp"
android:clickable="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:srcCompat="#android:drawable/ic_menu_compass" />
</android.support.constraint.ConstraintLayout>

This is about how you display the map, actually your linearLayoutTmap exists at the end of the layout, but below that you are creating the map, so the map comes under linearLayoutTmap which contains the floating buttons.
what you have to do is that to put linearLayoutTmap inside a RelativeLayout in which you have to mention that linearLayoutTmap exists at the right bottom, in addition you have to change LinearLayoutTemp width & height to wrap_content instead of match_parent, and finally to put a fragment inside the RelativeLayout to display the map using it, so it will be all like the following:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.mapwithmarker.MapsMarkerActivity" />
<LinearLayout
android:id="#+id/linearLayoutTmap"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:gravity="bottom"
android:orientation="vertical">
<android.support.design.widget.FloatingActionButton
android:id="#+id/navigate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_marginRight="28dp"
android:layout_marginBottom="15dp"
android:clickable="true"
app:srcCompat="#drawable/location" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/current_location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_marginRight="28dp"
android:layout_marginBottom="65dp"
android:clickable="true"

CardView size issue on View Recycle

I have created a recyclerview adapter class, with an item layout which contains a cardview inside which there are some textviews and imageviews. The problem I am facing is that when the views are recycled, my cardview size changes and it hides the content of another cardview.
I think the issue is because I have different card heights for each item. So when an item is recycled, it takes the height of another card which is different. How to fix this? Please help..

Android layout with fixed button on bottom

I have the following xml which is supposed to be something similar to the following
The activity shows mostly ok, but i cant get the two down buttons to get fixed to the bottom of the screen without messing the top views.
I've tried to use a FrameLayout with two RelativeLayouts, alignment_bottom, an empty view with weight 1 between components and even still havent being able to accomplish my goal. Any help will be really appreciated, thank you in advance.

android:id="#+id/exit_group"

Use Coordinator Layout as a parent layout. like this.
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:card_view="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="false">
// your code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:orientation="horizontal">
<TextView
android:id="#+id/txt_contact_laksha_group"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="demo"
/>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>

How place overlay imageview on two layouts?

I want to build the following screen which contains app logo, success/failure icon image, information message and ok button.
Here this the code. I am using linear layout to achieve this.
<LinearLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:background="#android:color/white"

How to place success/failure icon image on top of the two layouts?

You can use constraint to make it easy
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.constraint.Guideline
android:id="#+id/center"
android:layout_width="0dp"
android:layout_height="0dp"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.5"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#id/center"
android:background="#ffffff"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="#id/center"
app:layout_constraintBottom_toBottomOf="parent"
android:background="#00ffff"/>
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:background="#ff8801"
app:layout_constraintTop_toTopOf="#id/center"
app:layout_constraintBottom_toBottomOf="#id/center"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent" />
</android.support.constraint.ConstraintLayout>
Output:

Try this
<?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"
android:layout_width="match_parent"

android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#mipmap/ic_launcher_round" />
</RelativeLayout>
</RelativeLayout>
OUTPUT

Parent RelativeLayout
add child LinearLayout as fillParent and assign weightsum 2. add two
layouts with 1 weight each. (add individual implementation for each
layout according to your requirements.)
add second child in relative
layout as imageview/button for that good sign and set it center in
parent.
This will fix your problem

Here is an image i am following :
I just want to add the player who scored the goal with the football icon foreach side of the vertical red line.
Should i create two recyclerview?
Any suggestions please?

If you are using LinearLayout with weight property you can reslove this issue..
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="100">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_one"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="50"/>
<View
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#android:color/holo_red_dark"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_two"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="49"/>
</LinearLayout>
try this..
