How can I Embed text inside image?

I want to display a custom text (mainly person info) inside an image like it's shown above. How can I do it in android? For example, I have a known size of this image (it differs from device to device) and want to display it with the different text size inside it in the special place.

You can use, for example, RelativeLayout.
Make your ImageView be match_parent and use some container for your text lines in bottom of parent RelativeLayout.
Example:
<?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="match_parent">
<ImageView
android:scaleType="fitXY"
app:srcCompat="#drawable/ic_launcher_background"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:padding="20dp"
android:background="#92fffaaa"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="200dp">
<TextView
android:textSize="20sp"
android:text="Some test text"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</RelativeLayout>
Result:

Try this (adjust dimensions as your requirement)
<RelativeLayout
android:layout_width="200dp"
android:layout_height="150dp">
<ImageView
android:scaleType="centerCrop"
android:src="#drawable/your_image"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:background="#64000000"
android:padding="8dp"
android:gravity="center_vertical"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:text="Title"
android:textColor="#ffffff"
android:textSize="16sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:text="Sub Title"
android:textColor="#ffffff"
android:textSize="14sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

I've done something similar previously.
Use Framelayout.
Add ImageView in frame layout with match_parent constraints.
Add LinearLayout having background="#80000000" and layout_gravity="center" in FrameLayout which contains your two TextViews.
Let me know in case this does not work.

Make an Imageview assume the biggest width allowed by its parent

I want an Imageview to expand and assume the biggest width respecting the parent viewgroups margins. The width of the parent must however behave like wrap_content when the ImageView is dynamically hidden.
Consider the following layout:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="8dp"
android:paddingRight="8dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:src="#drawable/strasse_hintergrund"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Short Text"/>
</LinearLayout>
The following images show what the layout looks like, both with a short and a long text in the textview:
I need the ImageView to always have assume width as in the second version (with the long text).
What is the best way to achieve this?

Try this :
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/strasse_hintergrund"/>
and maybe change :
android:layout_width="match_parent"
to
android:layout_width="wrap_content"
EDIT :
Here is my code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="19dp"
android:background="#color/dark"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:layout_weight="0.02">
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="7pt"
android:textColor="#color/white"/>
</android.support.v7.widget.Toolbar>
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
/>
<TextView
android:id="#+id/textView"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="10pt"/>
</LinearLayout>
Result :

Place TextView and ImageView in different LinearLayouts and place both inside a third LinearLayout OR
use match_parent instead of wrap_content for your TextView width

You can set this android:scaleType="fitXY" property for Imageview
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/your_image"/>

How to center fit image in linear layout?

I have an xml screen with three children linear layouts in a parent linear layout of vertical orientation. First child contains an image view and when running the application I can not view any image. Why? is the image size too big?? If so.. how to scale it? However Image is view able in my design tab. of android stdudio. Below is my complete code for xml file.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_sign_up"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.root.my_laoder.SignUp"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:adjustViewBounds="true"
android:scaleType="centerInside"
android:src="#drawable/ty"
/>
</LinearLayout>

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:orientation="vertical"

<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textPassword"
/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="number"
/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"

<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.5"
/>
</LinearLayout>
</LinearLayout>

1. Add attribute android:gravity="center_horizontal" to LinearLayout, to show ImageView in center.
2. Update ImageView width to android:layout_width="wrap_content" and remove attribute android:layout_gravity="center".
3. Use android:scaleType="fitXY" instead of android:scaleType="centerInside"
Try this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_sign_up"

android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:orientation="vertical">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/ty" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:orientation="vertical"
android:paddingTop="50dp">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textPassword" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="number" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingTop="50dp">
<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.5" />
<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.5" />
</LinearLayout>
</LinearLayout>
OUTPUT:

what are the dimens values for these parameters?
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
and why you are using separate linearlayout for imageView even with parent layout as linear?
kindly remove that
have you checked the size of image you are using as a background in ImageView? if size is large than probably image is pushing your rest of your views out of the screen.try to give fixed width and height let's say 100dp for both and see if you are able to see anything.
If you wanna make imageView centre horizontally use in ImagView view
android:layout_gravity="center_horizontal"
above line of code will not work with separate linear layout for ImageView. If you are gonna use separate layout for ImageView anyway, use below line of code inside that linearlayout
android:gravity="center_horizontal"
Note: sorry I'm not able to leave a comment.

Try this for your ImageView:
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:adjustViewBounds="true"
android:scaleType="centerInside"
android:src="#android:drawable/btn_minus" />

I think you missed scaleType of ImageView, Follow the steps to make your image center
1. Add attribute android:layout_gravity="center_horizontal" to show ImageView in center.
2. Set ImageView layout_width="match_parent" and
layout_height="#dimen/fixed_height"
==> height will be fixed but width will automatically adjust
according to device size
3. and set scaleType="fitEnd" or scaleType="fitCenter"
==> fitEnd is ( Scale the image from the end of the container ) and
possible to have space on top
if image is different each time.
==> fitCenter is (Scale the image from center) and possibility to
have space in top and bottom
Example:
<ImageView
android:id="#+id/cover_image"
android:layout_width="match_parent"
android:layout_height="#dimen/fixed_height"
android:layout_gravity="center_horizontal"
android:scaleType="fitEnd" />

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

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: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:layout_height="70dp"

</RelativeLayout>

Android how to overlap an ImageView on top of a LienearLayouy so that they have the same size?

Hi and thanks for any suggestion.
I need to put an ImageView to overlapp over a LinearLayout.
I have tried this:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/background"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<ImageView
android:id="#+id/backgroundimage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/gradient_box"
android:layout_gravity="center"
/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical"
android:layout_gravity="center">
But this is the result I get (the ImageView shrinks to a single line)
I have tried using RelativeLayout, this is the result I get.
CLOSE, but the ImageView now expands to fill all the available space and does not "wrap content" as I need to.
The desired result would be like this:
PS: I cannot use android:background="image" because i need to change it at runtime.

You can use a Relativ Layout that contains the LinearLayout and then align the ImageView with the LinearLayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/background"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/linear"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical"
android:layout_gravity="center">
<ImageView
android:id="#+id/backgroundimage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/gradient_box"
android:layout_alignLeft="#id/linear"
android:layout_alignRight="#id/linear"
android:layout_alignTop="#id/linear"
android:layout_alignBottom="#id/linear"
android:layout_gravity="center"
android:scaleType="fitCenter" />
If you just want to set the image as a background you can just set a background image for the linear layout:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/background"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/blue" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical"
android:background="#drawable/gradient_box"
android:layout_gravity="center">

PS: I cannot use android:background="image" because i need to change it at runtime.
Why not? Use setBackgroundResource.
