I am using this PNG in my project (within my resources):
Programmically, I want to achieve this:
Change color to white.
Add a solid-colored circle around the icon.
The result should look to something like this:
The red color has to be changeable dynamically at runtime. How do I achieve this?
Add this to your XML file:
<ImageView
android:id="#+id/image_view"
android:layout_width="56dp"
android:layout_height="56dp"
android:background="#drawable/circle"
android:padding="8dp"
android:src="#drawable/bull_image"
app:tint="#android:color/white" />
This is circle.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#android:color/white"/>
</shape>
And to change the background color dynamically:
imageView.backgroundTintList = ColorStateList.valueOf(ContextCompat.getColor(this, R.color.your_color))
Something like this shoud do the trick (adjust the cardCornerRadius to your liking):
<androidx.cardview.widget.CardView
android:layout_height="wrap_content"
app:cardBackgroundColor="#color/red"
app:cardCornerRadius="10dp"
android:layout_width="wrap_content"
app:cardElevation="0dp">
<ImageView
android:src="your_image"
android:tint="#color/white" />
</androidx.cardview.widget.CardView>
Define a drawable that you can use as your background, for example:
<!-- res/drawable/the_drawable_above.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" android:padding="10dp">
<stroke android:width="1dp"
android:color="#color/colorLightGrey"/>
<solid
android:color="#color/colorAccent"/>
</shape>
For your image view:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="#drawable/your_image"
scale_type="fit_center"
android:tint="#android:color/white"
android:background="#drawable/the_drawable_above"/>

I have a shape in android button, i wanted it colored two colors. but not gradient. just the colors as is , how can it be done? below is my drawable. I dont want it gradient, just two colors as is.
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<gradient

android:endColor="#e574bd"
android:startColor="#874dbc"
android:type="linear" />
<corners
android:radius="20dp"/>
</shape>
Edit: I attached image how I want it to look like
<RelativeLayout
android:id="#+id/registration"
android:layout_width="match_parent"
android:layout_height="#dimen/buttonHeight"
android:paddingEnd="#dimen/default_margin"
android:paddingStart="#dimen/default_margin"

I have a SeekBar with a progressDrawable.
<SeekBar
android:id="#+id/seekbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"
android:progress="50"
android:progressDrawable="#drawable/image"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent" />
In this seekbar I used the image.png
My phone's screen is bigger, than this image. So I want to use this image like "fitXY" .
Actually it's multiply the image.
How can I set the image to match_parent?
Thank you !
Try this one
<SeekBar
android:id="#+id/seekbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"
android:progress="50"
android:progressDrawable="#drawable/seekbar_bg"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent" />
Drawble folder
seekbar_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:left="300dip">
<shape

android:shape="rectangle" >
<solid android:color="#0000FF" />
</shape>
</item>
<item android:right="400dip">
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#ff0000" />
</shape>
</item>
</layer-list>
You can use 9-patch.
I just made it in paint, so probably there is some error, but hope you get the idea. Also you can make image smaller, to reduce its size.
Im trying to achieve something like this, I used layer list in the xml this way :
<item>
<shape android:shape="rectangle" >
<gradient
android:centerColor="#4DD0E1"
android:endColor="#76FF03"
android:startColor="#color/colorPrimary"
android:type="linear" />
</shape>
</item>
<item
android:bottom="2dp"
android:left="2dp"
android:right="2dp"
android:top="2dp">
<shape android:shape="rectangle" >
<solid android:color="#fff" />
</shape>
</item>
Here is the layout code, the border of the shape needs to overlap the image.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_marginTop="12dp"
android:background="#android:color/transparent">
<ImageView
android:layout_width="100dp"
android:layout_height="75dp"
android:layout_centerVertical="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_marginRight="12dp"
android:id="#+id/goals_image" />
<FrameLayout
android:id="#+id/goals_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:clickable="true"
android:layout_marginLeft="20dp"
android:layout_marginRight="32dp"
android:background="#00000000"
>
<TextView
android:id="#+id/goals_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="15dp"
android:text="Lose Weight"
android:textColor="#color/black"
android:layout_margin="40dp"
/>
</FrameLayout>
</RelativeLayout>
but if I set the background to transparent the shapes background becomes the whole gradient color. How can i achieve a gradient stroke with a transparent background? Thanks in advance.
Just use an 8-digit color value, e.g. #FFF8F8F6, where the first two characters are the alpha value. FF being fully opaque, and 00 being fully transparent.

I want to add a gradient on the bottom of my image . Something like this :
I tried something like this but I only get the gradient no image..
<ImageView
android:id="#+id/trendingImageView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/trend_donald_sterling"
android:src="#drawable/trending_gradient_shape"
/>
trending_gradient_shape:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="90"
android:endColor="#android:color/darker_gray"
android:startColor="#android:color/darker_gray" />
<corners android:radius="0dp" />
</shape>
You need two layers: An ImageView, and a View on top of that with your gradient as android:background. Put these two Views in a FrameLayout:
<FrameLayout
... >
<ImageView
...
android:src="#drawable/trend_donald_sterling" />
<View
...
android:background="#drawable/trending_gradient_shape"/>
</FrameLayout>
Simply set the alpha value in your gardient.xml:
Your imageView:
android:background="#drawable/trend_donald_sterling"
android:src="#drawable/trending_gradient_shape"
Your gradient xml file:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="90"
android:endColor="#00ffffff"
android:startColor="#aa000000"
android:centerColor="#00ffffff" />
<corners android:radius="0dp" />
</shape>
In the color value, the first two places after # correspond to the alpha value, while the rest are the actual color value in R G B format, two for each.
try using the "foreground" attribute in your imageview
<ImageView
...
android:src="#drawable/trend_donald_sterling"
android:foreground="#drawable/trending_gradient_shape" />
it worked for me.
Use android:foreground="..." instead of android:background="..."
Now you won't need to put ImageView and View inside a FrameLayout!
So your final code will be:
ImageView
<ImageView
...
android:foreground="#drawable/trend_donald_sterling"/>
Drawable
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="90"
android:endColor="#00ffffff"
android:startColor="#aa000000"
android:centerColor="#00ffffff" />
<corners android:radius="0dp" />
</shape>
this is how im gonna do,
i used relative layout as my parent layout, use the following code
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="#drawable/img_sample"/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/gradiant"/>
<LinearLayout
android:layout_marginLeft="10dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
<View
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.55"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="0.25"
android:text="Events"
android:gravity="bottom"
android:textStyle="bold"
android:textSize="18sp"
android:textColor="#ffffff"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="0.25"
android:text="Some description about the events goes here"
android:textSize="14sp"
android:textColor="#ffffff"/>
</LinearLayout>
</RelativeLayout>
hope you can figure out, here i attach my gradiant code below.use it inside the drawable folder....
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="90"
android:endColor="#00ffffff"
android:startColor="#aa000000"
android:centerColor="#00ffffff" />
<corners android:radius="0dp" />
</shape>
This is an easy way that creates a similar effect yet doesn't actually have the image disappear. Sometimes using the foreground attribute is not the best for the gradient, especially if using a motionlayout or you have nested scrollviews. Create an entirely new imageview and set the background to the gradient.
XML With Both Imageviews
<ImageView
android:id="#+id/main_imageView"
android:layout_width="0dp"
android:layout_height="0dp"
android:scaleType="centerCrop"
android:src="#drawable/peakpx__1_"
ads:layout_constraintHeight_percent=".55"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageView
android:id="#+id/main_imageView_gradient"
android:layout_width="0dp"
android:layout_height="0dp"
ads:layout_constraintHeight_percent=".55"
android:background="#drawable/gradient_theme_background"
app:layout_constraintEnd_toEndOf="#id/main_imageView"
app:layout_constraintBottom_toBottomOf="#id/main_imageView"
app:layout_constraintStart_toStartOf="#id/main_imageView" />
Then for the gradient, I use black #000000 for darker themes, and white #ffffff for lighter ones. A lot of answers I see on this are not adding the center color. This is important if you want to have the gradient start closer to the edge of the image.
gradient_background
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="270"
android:type="linear"
android:endColor="#ff000000"
android:centerColor="#00000000"
android:startColor="#00000000"/>
</shape>
**1> Create file black_shadow.xml**
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:angle="270"
android:startColor="#00000000"
android:centerColor="#9c000000"
android:endColor="#000000"
android:type="linear" />
</shape>
</item>bla
</selector>
**2> Just add below line in Imageview.**
android:foreground="#drawable/black_shadow"
Is it possible to draw a shape in xml, and use a png as the background to that shape? I already have the shape (it's a square with rounded corners), and i would like to put a background to that square.
Yes you can use any shape file as background for any view. This sample create rounded background with white color and black border around the shape.
Sample :
rounded_corner.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp" />
<stroke
android:width="0.5dp"
android:color="#color/color_grey" />
<solid android:color="#color/color_white" />
</shape>
u can use this as,
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:background="#drawable/rounded_corner"
android:orientation="vertical" >
//try this way this will help you
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/rounded_corner"
android:padding="2dp"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/yourdrawable />
</LinearLayout>
