TextView in RelativeLayout improper alignment

I need to implement the following UI:
For this, I am using the following layout:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white">
<ImageView
android:id="#+id/news_image0"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="#dimen/news_cell0_imageview_min_height"
android:adjustViewBounds="true"
android:scaleType="fitXY" />
<RelativeLayout
android:id="#+id/news0_cell_image_overlay_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignBottom="#+id/news_image0"
android:layout_alignTop="#+id/news_image0"
android:layout_alignLeft="#+id/news_image0"
android:layout_alignStart="#+id/news_image0"
android:layout_alignEnd="#+id/news_image0"
android:layout_alignRight="#+id/news_image0"
android:background="#drawable/news_cell0_overlay_gradient">
<TextView
android:id="#+id/news_title0"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:gravity="center_vertical|start"
android:layout_alignParentBottom="true"
android:maxLines="3"
android:ellipsize="end"
android:textColor="#color/colorNewsCellType0TitleText"
android:layout_margin="#dimen/news_cell0_textview_margin"
android:textSize="#dimen/news_cell0_title_text_size"
android:typeface="monospace" />
</RelativeLayout>
</RelativeLayout>
Into the ImageView I am loading image using Picasso from a URL. I am getting output correctly in most of the devices, but in some of the devices running android less than Lollipop, this shows up like the screenshot below. The text shows up at the top, instead of bottom. But I have set android:layout_alignParentBottom="true" for the TextView. The RelativeLayout is rendered correctly, and it fits the image(it has a background gradient, which can clearly be seen at the bottom of the image).
What is causing this problem and how can I solve this?

You can try with FRAMELAYOUT
FrameLayout is designed to block out an area on the screen to display
a single item. Generally, FrameLayout should be used to hold a single
child view, because it can be difficult to organize child views in a
way that's scalable to different screen sizes without the children
overlapping each other.
<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_launcher"
android:scaleType="fitCenter"
android:layout_height="fill_parent"
android:layout_width="fill_parent"/>
<TextView
android:text="Hi.."
android:textSize="17sp"
android:textStyle="bold"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:gravity="center|bottom"/>
</FrameLayout>

You can try this layout,
<?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="wrap_content"
android:background="#android:color/white">
<ImageView
android:id="#+id/news_image0"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:minHeight="100dp"
android:scaleType="fitXY"/>
<TextView
android:id="#+id/news_title0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/news_image0"
android:layout_centerHorizontal="true"
android:ellipsize="end"
android:maxLines="3"
android:padding="12dp"
android:text="fsdsdfdsdsfsdfsdf"
android:textColor="#f00"
android:typeface="monospace"/>
</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.
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/viewA"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:orientation="horizontal">
<TextView
android:id="#+id/subject"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="20dp"
android:text="Thi"
android:textColor="#android:color/white"
android:textSize="17sp"
/>
</LinearLayout>
<LinearLayout

</LinearLayout>
</LinearLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:clickable="true"
android:src="#drawable/plus"
app:layout_anchor="#+id/viewA"
app:layout_anchorGravity="bottom|right|end"/>
</android.support.design.widget.CoordinatorLayout>
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>

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>

Distributing extra space in RelativeLayout

I'm trying to build a RelativeLayout which distributes excess space between its children, much as shown here:
I've figured out how to center the red widget inside the blue one, but what I also want to do is distribute any excess vertical space evenly above, below, and between the blue and olive widgets. Currently, everything is bunched up at the top.
My XML looks roughly like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
>
<ImageButton android:id="#+id/blue_button"
android:src="#drawable/blue_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_alignParentTop="true"
/>
<ImageView
android:id="#+id/red_box"
android:src="#drawable/red_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#id/blue_button"
android:layout_marginLeft="10dp"
android:layout_alignTop="#id/blue_button"
android:layout_alignBottom="#id/blue_button"
/>
<ImageButton
android:id="#+id/green_button"
android:src="#drawable/green_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/blue_button"
android:layout_weight="1"
/>
</RelativeLayout>

First, you are using layout_weight with RelativeLayout parent. It's useless because layout_weight works only with LinearLayout parent.
Actually I didn't understand your question (an image of wanted layout would be good) but I guess this will work for you:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center_horizontal"
>
<RelativeLayout
android:id="#+id/blueAndRedWrapperLay"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<ImageButton android:id="#+id/blue_button"
android:src="#00CCFF"
android:layout_width="300dp"
android:layout_height="200dp"
android:layout_weight="1"
android:layout_centerInParent="true" />
<ImageView
android:id="#+id/red_box"
android:src="#ff0000"
android:layout_width="100dp"
android:layout_height="70dp"
android:layout_centerInParent="true"
/>
</RelativeLayout>
<RelativeLayout
android:id="#+id/greenWrapperLay"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<ImageButton
android:id="#+id/green_button"
android:src="#669900"
android:layout_width="300dp"
android:layout_height="200dp"
android:layout_centerInParent="true"
/>
</RelativeLayout>
</LinearLayout>

LinearLayout above ImageView not getting displayin Fragment?

I have ImageView which needs to be shown in full height available. However at top i have created LinearLayout which contains Text and Image. I want it to display at top but also want to image to fit screen. I have linear layout at bottom and its working fine.
This is my code for LinearLayout which i want to show at top. I have hidden actionbar
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/actionbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#android:color/black"
android:gravity="top"
android:orientation="horizontal"
android:visibility="visible" >
<ImageView
android:id="#+id/backbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:paddingLeft="10dp"
android:src="#drawable/back_button" />
<TextView
android:id="#+id/titleofscreen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Testing"
android:textColor="#22c064"
android:textSize="18sp" />
</LinearLayout>
<ImageView
android:id="#+id/imageShown"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY" />
</FrameLayout>
If i dont set imageView scale type to android:scaleType="fitXY" then it works but image doesnt fit screen.
I want to display image to fit between above bar which contains Text and below it has some icons. But if i make image scaletype ='fitXY' it doesnt display above text. Following is screenshot but i want image to occupy space

If you want the image to be below the actionbar you should not use the FrameLayout as a parent. You either should use vertical LinearLayout with weight or `RelativeLayout". Try following code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/actionbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#android:color/black"
android:gravity="top"
android:orientation="horizontal"
android:visibility="visible" >
<ImageView
android:id="#+id/backbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:paddingLeft="10dp"
android:src="#drawable/back_button" />
<TextView
android:id="#+id/titleofscreen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Testing"
android:textColor="#22c064"
android:textSize="18sp" />
</LinearLayout>
<ImageView
android:id="#+id/imageShown"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/actionbar"
android:layout_alignParentBottom="true"
android:scaleType="fitCenter"
/>
</RelativeLayout>
Also I doubt that you use fitXY as android:scaleType, because it doesn't maintain the aspect ratio of the image - so your image will be deformed (stretched). In your case you should rather use fitCenter, but it depends on how exactly you want to scale your image - you can also play with centerInside or centerCrop.

Relative Layout containing FrameLayout and few other components

firstly excuse me for terrible naming with the subject.
I have the following layout setup:
<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"
tools:context=".PersonDetails" >
<FrameLayout
android:id="#+id/bannerLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:id="#+id/coverImage"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scaleType="fitStart"
android:src="#drawable/default_cover">
</ImageView>
<ImageView
android:id="#+id/thumbImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left|bottom"
android:scaleType="fitStart"
android:src="#drawable/fingerprint_ic" />
</FrameLayout>
<TextView
android:id="#+id/textName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text"
android:textColor="#55FF55"
android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>
What i am trying to achieve is to have a banner (much like facebook cover that spans across the top of the screen). And have a thumbnail photo at the corner left of the banner.
The height of the banner should only takes up about 1/4 of the height of the screen. Since i would need the rest of the space for other components.
Immediately below the banner i would like to have a TextView (on the leftside) and a button on the rightside.
So far i can only able to put the thumbnail on top of the banner, but i don't know how to place it on the lower left (i could set it using marginTop but, i believe this is not the correct way of doing it).
Does anyone know how to achieve this? Thanks.
EDIT #1:
Here is the UI

From your description i think you want to make something like this:
I used a linearlayout with 2 layouts as content. Using the android:layout_weight attribute we can make the top layout take up 1/4th of the space, while the bottom layout has the rest to use.
Then to position the icon in the top layout we use alignParentBottom to make it stick to the bottom.
<LinearLayout 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"
tools:context=".PersonDetails"
android:orientation="vertical">
<RelativeLayout
android:id="#+id/bannerLayout"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1">

android:layout_width="fill_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
android:src="#drawable/default_cover"></ImageView>
<ImageView
android:id="#+id/thumbImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:scaleType="fitStart"

android:textSize="40dp"
