Im trying to align my layouts as shown in the Metrics and Keylines webpage for Material Design,
http://www.google.com/design/spec/layout/metrics-and-keylines.html#metrics-and-keylines-ratio-keylines
Having trouble figuring out how to apply this to my layouts, how can I do this in xml? Thanks for any help
If you don't have an image to use with the desired aspect ratio (or one is not needed), you could use a placeholder. For instance, I created a shape drawable with dimensions 16px by 9px and used it to adjust the bounds of a relative layout:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/ratio16x9"/>
</RelativeLayout>
ratio16x9.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<size android:width="16px" android:height="9px"/>
</shape>

I have a shape. I am using a random color to fill the shape.
I have an image which needs to be set for the background of this shape. (I am just thinking it should be background. May be I am using wrong words. )
Result should be something like this (note the image at the background).
I recommend you that library which you can custom corners , shape and other things and then you can put your image view inside it and then you'll have your view
here is the link
https://github.com/florent37/ShapeOfView
You can set src of your image view to those white things you have, then you will have your shape as background and this pattern on it as well.
use android:src
If you want to show an image within a shape, Try this,
shape.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/colorPrimaryDark"/>
<corners android:bottomLeftRadius="56dp"/>
</shape>
Now set the shape for a layout, then add the image that you want in image view then adjust the alpha value to show both shape and image,
layout.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="120dp"
android:background="#drawable/shape">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/blue_image"
android:alpha=".2"/>
</RelativeLayout>
Output will be like this
Hope this will help.
I came across with this library. RoundedImageView Github link
All I needed to do was:
<com.makeramen.roundedimageview.RoundedImageView
android:layout_width="0dp"
android:layout_height="200dp"
android:src="#drawable/add_card_head_bg"
android:scaleType="centerCrop"
app:riv_corner_radius="90dip"
app:riv_mutate_background="true"
app:riv_corner_radius_bottom_left="50dp"/>
This is what I am trying to achieve
The black rectangle is an image asset which i need to move left and right on related touch events/drags
Being relatively new to Android , I am finding this difficult to implement.
So was hoping I could get some tips,guides,examples if there are any.
EDIT:
I Have tried viewflipper but that is not what I need here,
I tried making a slider like a seek bar , but didn't work out.
Some one suggested that I use a framelayout over the main image to slide but I don't know how to do it.
So any help which will help me out here is appreciated
Use SeekBar because it suits your needs completely.
First create a drawable xml file named "rect_border.xml" in res/drawable folder with these contents:
// **EDITED**
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:color="#000000"
android:width="5dp"
/>
// change the width to any value that suits your needs.
// set the height property greater than your image height
<size android:width="50dp" android:height="360px" />
</shape>
Then in your layout:
// **EDITED**
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="300px"
android:layout_centerVertical="true"
android:scaleType="fitXY"
android:src="#drawable/your_image"
/>
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:thumb="#drawable/rect_border"
android:progressDrawable="#android:color/transparent"
/>
</RelativeLayout>
I tested it and I'm sure it's actually what you want (as described).
So what's the problem about the SeekBar?
My current approach:
I create Rectangle in separate file:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid>#color/red</solid>
</shape>
And later I reference it in my layout like this:
<ImageView
android:id="#+id/rectimage"
android:layout_width="17dp"
android:layout_height="17dp"
android:src="#drawable/rectangle">
</ImageView>
How to change the color in xml layout? I'd like to have different color for each rectangle, but I don't want to create separate drawable files for each of them.
The answer is very simple.
<ImageView
android:id="#+id/rectimage"
android:layout_width="17dp"
android:layout_height="17dp"
android:src="#drawable/rectangle">
android:background="#color/blue"
</ImageView>
All is needed is to set background color. My failure was to set unsupported in 2.3 colors, so the rectangles were black.
You cannot change the value of drawable xmls. All you can do is to create the rectangles using ShapeDrawables.
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"
I want to draw an image with gradient background. I've created a drawable bitmap resource like below
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/bg"
android:tileMode="repeat"
android:gravity="bottom"
/>
As you know, gravity is ignored when tileMode is defined. I tried creating my own class which is inherited from BitmapDrawable, but I couldn't achieve success with that.
Please help me to apply both properties: tileMode and gravity.
I did not understand the question clearly. What is the goal here?
Is it using a gradient image (like .png .jpg) with tileMode?
Or is it using a transparent icon and making it's background gradient?
Also why would you need gravity when you are using tileMode? tileMode means tile the whole area of bitmap with the same image. Since it will do it to the whole image no point giving gravity on that image since all of it will be filled.
If the goal is to use this drawable bitmap in the some part of the screen add this to your layout:
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/mydrawablebitmap"
android:id="#+id/imageview1" />
You can put it to your layout.xml and set your own width and height and align whichever you like.
If the goal is using an image and making its background here is how you go with it:
Create a gradient.xml in your drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#E0E0E0"
android:endColor="#FFFFFF"
android:angle="-90"/>
</shape>
Then add this imageview to your layout:
<ImageView
android:id="#+id/myimagewithgradientbackground"
android:layout_width="match_parent"
android:layout_height="160dp"
android:background="#drawable/gradient"
android:src="#drawable/foregroundimage" />
If you give me some more details about the question I'll go ahead and edit my answer accordingly.
