How can I do transparent view. Can anybody help me?
I want to do just like this:
create one layout and make theme as dialog in your manifest
and in your layout set background as android:background="#885A2720"
EDIT:
check this layout in your view
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:minWidth="250dp"
android:minHeight="380dp"
android:layout_gravity="center_vertical|center_horizontal"
android:background="#885A2720" style="#android:style/Theme.Holo.Dialog">
</LinearLayout>
You should just be able to change the opacity/alpha of the overlay.
If you would use relativeLayout then use imageView with height and width match_parent.
And set alpha of an image to 150dp.
Use drawables to draw the rectangles
For complete transparency, use the following drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<solid android:color="#00000000" />
<stroke android:width="0.3dip" android:color="#2f4f4f"
android:dashWidth="7dip"
android:dashGap="7dip"/>
</shape>
If you want to set % transparency, u can set the "Alpha"property of the widget used. Note that a text box with nothing in it can help you achieve that.

I want to make my ImageView curved at the bottom with shadow effect.
Similar to this image
But I don't have any idea about how to do this.
Whenever I search on Google or StackOverflow it shows me results related to curved corners but I want curved edge at bottom.
you can make shape use layer-list
for example,
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:left="-150dp"
android:right="-150dp"
android:top="-200dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#C72C2F" />
</shape>
</item>
</layer-list>
it show like this.
And then use this in background,
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout
app:layout_constraintTop_toTopOf="parent"
android:background="#drawable/round"
android:elevation="30dp"
android:layout_width="match_parent"
android:layout_height="700dp"/>
</androidx.constraintlayout.widget.ConstraintLayout>
it make like this.
Also for make shadow effect, I use android:elevation it make shadow, and if you increase value, it can make more depth.
And obviously add image view for show images. I believe you can do this.
In my Android application I have one view it may be ImageView or TextView how can I set shadow effect for View in android? I have set the shadow by using the following code, but it won't work:
view.setElevation(130)
Please help me to solve this
You can create your own "shadow view"
<View
android:id="#+id/shadow_view"
android:layout_width="match_parent"
android:layout_height="4dp"
android:layout_gravity="bottom"
android:background="#drawable/shadow_gradient" />
and add the shadow drawable to it:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="90"
android:endColor="#android:color/transparent"
android:startColor="#8f000000" />
</shape>
The height is up to you, to experiment and see what works best for you as is the angle and start colour of the drawable. You just need to align this view layout to any view layout you want to have a shadow and you are good.
I'm in need of creating a receipt layout in Android. The idea is very simple, a rectangle layout with a zigzag top.
Even, i have tried dashed line but nothing working.
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:color="#FF00"
android:dashWidth="5dp"
android:dashGap="5dp" />
</shape>
Try with this: https://github.com/beigirad/ZigzagView
Support top and bottom Zigzag.
<ir.beigirad.zigzagview.ZigzagView
android:layout_width="match_parent"
android:layout_height="240dp"
app:zigzagBackgroundColor="#8bc34a"
app:zigzagElevation="8dp"
app:zigzagHeight="10dp"
app:zigzagShadowAlpha="0.9"
app:zigzagSides="top|bottom"
app:zigzagPaddingContent="16dp">
// add child view(s)
</ir.beigirad.zigzagview.ZigzagView>
Hi you can use this library android-shape-imageview. And use transparent shape like this
End use library.
<com.github.siyamed.shapeimageview.mask.PorterShapeImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:siShape="#drawable/zigzag"
android:src="#drawable/neo"
app:siSquare="true"/>
You can change app:siShape="#drawable/zigzag" to desired shape. You can create other png shape.
Create small triangle and use repeat background
repeat_background.xml
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/imagename"
android:tileMode="repeat" />
and use it in any view
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/repeat_background" />
refer this and this for more
I'm trying to create a view as tutorial for my activity. I need to show only some text with a translucent background an leave a "hole" transparent to see the background button of the original activity. I can use a framelayout with two different sub-layout (the original one and the tutorial one) and I can set visible/invisible the tutorial layout. The problem is: I don't know how I can create a "hole" in the tutorial sub-layout. How can I do?
background colors should transparent, opaque
I hope, it will work for you.
circle_background.xml file
<shape
android:shape="ring"
android:useLevel="true"
xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/blue_pressed" />
</shape>
view_background.xml
<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"
android:background="#drawable/circle_background"
>
//add more views if u wanto
</LinearLayout>
For create a "hole" or circular view you need create a drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#android:color/transparent" />
</shape>
And create a imageview in the position and size that you want and set this drawable like background.
Also you can use #00000000 intead #android:color/transparent
Or use TutorialView library on github
In my application, I want to display videoview as a rounded corners. I have tried placing videoview/surfaceview inside linearlayout with rounded corner set to linearlayout. but it does not work perfectly. I can not set rounded corner to videoview/surfaceview. I want to set view as below image:
Anyone have idea how to do this?
Not sure why there are so many bad answers when the solution is really simple (as long as you're min sdk > 21). Creating a shape and putting it overtop of the video won't work because you obviously want the background to be transparent to see the views behind it.
I found the answer here Android View Clipping. You just put the video view in a frame layout, add a rounded background to the frame layout, add an outline provider and clip the frame layout to the outline.
The background rounded_video_background:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#000000"/>
<corners android:radius="16dp" />
</shape>
The frame layout and video view inside of it:
<FrameLayout
android:id="#+id/video_view_container"
android:layout_width="90dp"
android:layout_height="120dp"
android:background="#drawable/rounded_video_background"
android:outlineProvider="background">
<VideoView
android:id="#+id/video_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
/>
</FrameLayout>
And the final step is clipping to the outline (didn't see a way to do it in xml so I did it programatically):
video_view_container.clipToOutline = true
Its worked for me,
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_gravity="center"
android:layout_width="match_parent"
card_view:cardCornerRadius="25dp"
android:layout_height="wrap_content">
<VideoView
android:id="#+id/video"
android:layout_width="match_parent"
android:layout_height="215dp" />
</android.support.v7.widget.CardView>
You can make it using a FramLayout & an XML drawable
FramLayout
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<VideoView
android:layout_width="match_parent"
android:layout_height="#dimen/dp_240"
android:layout_margin="#dimen/dp_24"/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rounded_corner_video_bg" />
</FrameLayout>
XML Drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="#dimen/dp_24"
android:color="#color/md_white_1000" />
<corners android:radius="#dimen/dp_24" />
</shape>
You could try layering different views on top of each other to create the rounded corners you are looking for. Try placing four ImageViews over the VideoView in each corner, to achieve the desired rounded corners. I have had success using a RelativeLayout to accomplish this, but you could also try using a FrameLayout to hold the Views together.
It is directly not possible, but you can do this by draw a imageview on top of videoview and set an image having transparent from between and solid color in rounded shape on the corners.

Its simple,
1. Create a drawable with rounded corners as mentioned by #sunil kumar
2. Set that drawable to your layout as a background
3. When using that layout set layout(your layout item name).clipToOutline = true
This is XML code of rounded VideoView.
<androidx.cardview.widget.CardView
android:id="#+id/videoCard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="16dp"
android:layout_marginBottom="16dp"
app:cardCornerRadius="20dp"
card_view:cardBackgroundColor="#color/white">
<VideoView
android:id="#+id/relativeVideo"
android:layout_width="match_parent"
android:layout_height="225dp"
android:paddingTop="-10dp"
android:paddingBottom="-10dp" />
</androidx.cardview.widget.CardView>
Negative padding is important otherwise height of VideoView is smaller than cardview by half of cornerRadius in both top and bottom side. You can set height whatever you want but negative padding should be half of cardCornerRadius all the time. Purple in the image is a video preview, not related to xml.
Have a nice day!
put rounded.xml in your drawable folder and set on framelayout of video like android:background="#drawable/rounded.xml"
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#FFFFFFFF" />
<corners android:radius="7dp" />
</shape>
Create an xml file in drawable folder called shape_video.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners android:radius="6dp" />
</shape>
Change the radius according to your rqmnt and in the background attribute of your videoview, give
android:background="#drawable/shape_video"
