Linear Layout behind ImageView in Relative Layout

Let me explain i have a xml like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imgCircle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/img_circle" />
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/imgCircle"
android:layout_toEndOf="#id/imgCircle"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
<TextView
android:id="#+id/mapCurrentLocation"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView1"
android:textColor="#color/lblTextColor"
android:textSize="#dimen/lblTextLarge"
android:textStyle="normal" >
</TextView>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView2"
android:textColor="#color/lblHintColor2"
android:textSize="#dimen/lblTextMedium"
android:textStyle="normal" >
</TextView>
</LinearLayout>
</RelativeLayout>
And this gives me Image and TextViews next to it
But i want to accomplish something like this
that TextView Background is extended (padding maybe) at the half of the Rounded Image (behind it) so that it looks like its "part" of the image. Or I was thinking of Making a view with background white that goes behind TextView so that it looks that way. But wanted to ask here maybe if there is a better way to do this.
I hope i was clear in explaining this (That is why I added pictures).

I have tried to use demo with your xml file and you can check below code. I had to give static height and width of the ImageView to achieve result.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/imgCarCircle"
android:layout_alignTop="#id/imgCarCircle"
android:layout_marginLeft="30dp"
android:background="#color/colorAccent"
android:orientation="vertical"
android:paddingLeft="40dp">
<TextView
android:id="#+id/mapCurrentLocation"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="text1"
android:textStyle="normal"></TextView>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="text2"
android:textStyle="normal"></TextView>
</LinearLayout>
<ImageView
android:id="#+id/imgCarCircle"
android:layout_width="60dp"
android:layout_height="60dp"
android:src="#mipmap/ic_launcher_round" />
</RelativeLayout>

try these:
first solution: change this
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/imgCircle"
android:layout_toEndOf="#id/imgCircle"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
to this:
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_marginLeft="20dp" // or just figure your image width and set this programatically
android:layout_height="wrap_content"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
second solution: it to use AbsoluteLayout which is a bit hard to handle.

Android, can't make text vertically center in TextView

I have a problem with making verticaly center text in TextView.
Android Studio in preview showing text correctly, in center like I want:
But when I will put app to device (Htc One m8, Android 6) then text is bottom (not in center of orange box (I set TextView to orange for better see where is problem).
Below text of xml layout, can see find where is a problem? ( I removed part of code, just added main relative and linear and line where is a problem)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="#dimen/main_relative_layout_height_medium"
android:layout_margin="#dimen/main_relative_layout_margin_medium"
android:orientation="vertical"
android:background="#color/widget_relative_layout_background_color"
android:paddingTop="#dimen/main_relative_padding_top_medium">
<!--android:updatePeriodMillis="86400"-->
<LinearLayout
android:id="#+id/contentContainer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:padding="#dimen/main_linear_layout_padding_medium"
android:paddingTop="#dimen/main_linear_layout_padding_top_medium"
android:paddingBottom="#dimen/main_linear_layout_padding_bottom_medium"
android:background="#color/widget_linear_layout_background_color"
android:weightSum="15"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true">
...
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="0dp">
<LinearLayout
android:orientation="horizontal"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="#dimen/times_row_size_medium"
android:paddingTop="0dp">
<LinearLayout

android:layout_width="wrap_content"
android:layout_height="match_parent">
<ImageView

android:layout_height="wrap_content"
android:id="#+id/firstWidgetImageView"
android:layout_column="1"
android:src="#drawable/ic_time_to_departure_white"
android:layout_gravity="center"
/>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:text="02:41"
android:layout_column="0"
android:textColor="#color/widgetTextColor"
android:id="#+id/firstTimeTextView"
android:textSize="#dimen/first_time_text_size_medium"
android:background="#color/application_button_color" />
</LinearLayout>
...
</LinearLayout>
</FrameLayout>

You have used center_horizontal in your TextView change it to center and you should be fine.
Code example:
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="02:41"
android:layout_column="0"
android:textColor="#color/widgetTextColor"
android:id="#+id/firstTimeTextView"
android:textSize="#dimen/first_time_text_size_medium"
android:background="#color/application_button_color" />

<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="02:41"
android:layout_column="0"
android:textColor="#color/widgetTextColor"
android:id="#+id/firstTimeTextView"
android:textSize="#dimen/first_time_text_size_medium"
android:background="#color/application_button_color" />
Please take a look at the above code . You need to replace gravity from center_horizontal to center .

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>

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>

Placing button to the right in android

I'm trying to create a view with 2 buttons on top(1 at left hand side of the screen and other on right side),a gesture overlay in between and another button at the bottom right of the screen.
Here the top right button isn't being placed on the right.. please help..
here is my code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
>
<LinearLayout android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="#+id/linearLayout1">
<ImageButton android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/add"
android:id="#+id/bBlog"></ImageButton>
<ImageButton android:layout_height="wrap_content"
android:layout_width="wrap_content" android:layout_gravity="right" android:background="#drawable/view" android:id="#+id/bBlog"></ImageButton>
</LinearLayout>
<RelativeLayout android:layout_height="fill_parent" android:layout_width="match_parent">
<android.gesture.GestureOverlayView android:layout_alignParentRight="true"
android:id="#+id/myoverlay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gestureColor="#000333"/>
<ImageButton android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/icon"
android:id="#+id/exit"></ImageButton>
</RelativeLayout>
</LinearLayout>

Try using a RelativeLayout with layout_alignParentLeft and layout_alignParentRight as such:
<RelativeLayout android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="#+id/linearLayout1">
<ImageButton
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:src="#drawable/add"
android:layout_alignParentLeft="true"
android:id="#+id/bBlog">
</ImageButton>
<ImageButton
android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:src="#drawable/view"
android:layout_alignParentRight="true"
android:id="#+id/bBlog">
</ImageButton>
Of course, you can add padding in there as necessary.

Check out answers of this for your question that why you are not able to set top right image button. For make it work, do change in your code as per Nick's answer given here. :)
