Create a Horizontal dotted line in android layout - android

in my layout I am trying to draw a DOTTED LINE.for drawing a horizontal line i am defining a view in my layout file.
<View
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="#drawable/customdots" />
and customdots.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:left="10dp"
android:right="10dp"
android:width="4dp"
android:drawable="#drawable/dotted" />
</layer-list>
dotted.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line" >
<size
android:height="4dp"
android:width="1024dp"/>
<stroke
android:width="4dp"
android:dashWidth="4dp"
android:color="#android:color/black"
android:dashGap="5dp"/>
</shape>
But i don't get any line using this code. please help me out.
When i use customdots.xml in the listView Divider as
android:divider="#drawable/customdots"
it shows a good dotted line

I was pulling my hair on this issue too until I figured out there is a bug in the latest versions of Android when rendering lines like this.
This bug can be circumvented by adding android:layerType="software" to the view which is using the dotted line as a background.
Example:
dotted.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:dashGap="3dp"
android:dashWidth="8dp"
android:height="2px"
android:color="#FFFFFF" />
</shape>
layout.xml:
<View
android:id="#+id/vDottedLine"
android:background="#drawable/dotted"
android:layout_width="match_parent"
android:layout_height="2px"
android:layerType="software" />

You can use following code . it may help you.
Create a dotted.xml in drawable folder like this...
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line" >
<stroke
android:color="#A52A2A"
android:dashWidth="10px"
android:dashGap="10px" />
</shape>
then use this xml in your layout with image view like this....
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is above line of code " />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="3dp"
android:layout_marginBottom="3dp"
android:src="#drawable/dottede" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="this is below code " />
</LinearLayout>

Android - Draw a ribbon shape

I am trying not to use image view. This is because, later, I will generate many objects with the same shape but different colors, so I wouldn't need to keep adding image views but simply adding colors on my code.
How can I create those images on Android Studio? I looked over Paint, onDraw, Canvas, etc, but this looks difficult to me.
If you want to use from XML , Try this way it will work
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<size
android:width="100dp"
android:height="40dp" />
<solid android:color="#5EB888" />
<corners android:radius="0dp"/>
</shape>
</item>
<item
android:top="-26dp"
android:bottom="31dp"
android:left="-90dp"
android:right="75dp">
<rotate
android:fromDegrees="45">
<shape android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>
</rotate>
</item>
</layer-list>
OUTPUT
You can create vector image using any vector program like Adobe Illustrator or convert it using a conversion tool like vectormagic or find already existing one then import it to android studio.
it will be imported as xml file where you can change the colors as you want
Create a drawable file as named left_arrow.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<rotate
android:fromDegrees="45"
android:toDegrees="90"
android:pivotX="0%"
android:pivotY="1%" >
<shape android:shape="rectangle" >
<stroke
android:width="10dp"
android:color="#00000000" />
<solid android:color="#ffffff" />
</shape>
</rotate>
</item>
Now, create a view layout to create this type of stripes or image like this, here is the below code:-
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/llMain"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.1"
android:background="#color/black"
android:orientation="horizontal">
<ImageView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.1"
android:background="#drawable/left_arrow"
android:contentDescription="#string/app_name" />
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.9"
android:contentDescription="#string/app_name" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.9" />
This above layout creates the required arrow stripe as a layout.
Now add this layout to your required layout where you wan't to show this stripes. For example,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:id="#+id/llMain"
layout="#layout/xtra"/>
</LinearLayout>
Now, you are able to also use OnClickListener by using "llMain".
Hope it will help.
You could use the white png image you already have and use the setColorFilter method on the image view class to tint it with any color you desire

semi-circle button android

I have two buttons and I want to change the shape of them to be semi-circles. Then place them beside each other to make a full circle. An image has been attached to show how I want the buttons to look. Any help would be greatly appreciated. Thank you.
You have to create one drawable xml file.
left_corner.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1dp"
android:bottomRightRadius="0dp" android:bottomLeftRadius="25dp"

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1dp"
android:bottomRightRadius="25dp" android:bottomLeftRadius="0dp"
android:topLeftRadius="0dp" android:topRightRadius="25dp"/> // here you have to put dimen as per reqiurement

Hope this will help~
Hi user23423534,
Applying xml shape as background to button and placing button side by side will help u solve the problem.
Please check the below code.
Layout file:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:layout_width="50dp"
android:layout_height="100dp"
android:background="#drawable/shape"/>
<Button
android:layout_width="50dp"
android:layout_height="100dp"
android:background="#drawable/shape1"/>
</LinearLayout>
shape drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#fff"/>
<corners android:bottomLeftRadius="50dp"
android:topLeftRadius="50dp"/>
</shape>
shape1 drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#fff"/>
<corners android:bottomRightRadius="50dp"
android:topRightRadius="50dp"/>
</shape>

Background transition to remove corner radius

We have a linearlayout that has a background which is partially rounded (only the right side), at a determinate moment we need to migrate that background to a not rounded one, so I thought about using the TransitionDrawable, but for some reason this is not working. This are my files:
R.drawable.bg_right_rounded:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/blue" />
<padding android:left="0dip" android:top="0dip" android:right="10dip" android:bottom="0dip" />
<corners android:topLeftRadius="0dp" android:topRightRadius="10dp"
android:bottomLeftRadius="0dp" android:bottomRightRadius="10dp"/>
</shape>
R.drawable.bg_blue:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/blue" />
</shape>
R.drawable.bg_transition:
<?xml version="1.0" encoding="utf-8"?>
<transition xmlns:android=
"http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/bg_right_rounded"/>
<item android:drawable="#drawable/bg_blue"/>
</transition>
Then the layout is something like:
<LinearLayout
android:id="#+id/vg_chat_typer_inner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#drawable/bg_transition">
....
</LinearLayout>
Then at a given moment we do:
TransitionDrawable transition = (TransitionDrawable) layout.getBackground();
transition.startTransition(1000);
If I do it in a normal situation it works fine, but when I put that linearlayout inside another linear layout with another one, then it stops working. The situation where it fails is the following one:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:layout_alignParentBottom="true">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal"
android:background="#drawable/bg_transition">
....
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="0">
....
</LinearLayout>
</LinearLayout>
Is it because of weight? Why is it not working?
Thanks in advance

set space between rows in listview Android

I have a listView with custom rows and I need to set a custom divider between each row.
This is the code of the listView:
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="#dimen/menu_padding"
android:background="#color/customBlue"
android:divider="#drawable/list_divider"
android:dividerHeight="2px" />
This is the code of the rows:
<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="50dp"
android:orientation="horizontal"
tools:ignore="contentDescription"
android:background="#color/strongBlue" >
<ImageView
android:id="#+id/row_icon"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="10dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/row_title"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:padding="10dp"
android:textColor="#color/white"
android:textAppearance="#android:style/TextAppearance.Medium" />
</LinearLayout>
And this is the code for the 2 pixel divider:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:bottom="1px">
<shape android:shape="line">
<stroke
android:color="#0C0832"
android:width="2dp"
/>
<size
android:height="1px"
/>
</shape>
</item>
<item android:top="1px">
<shape android:shape="line">
<stroke
android:color="#2D2E57"
android:width="2dp"
/>
<size
android:height="1px"
/>
</shape>
</item>
</layer-list>
The problem is that I have a random space between each row that has the same color as the listView backgroundColor and if I set the dividerHeight to 4px I can see my divider. How can I remove the space that gets created automatically and only have my custom divider?
Use the following code in rows in linear layout
android:layout_marginTop="15dp"
Instead of pixel you can provide dp in xml
android:dividerHeight="10dp"
android:divider="#ffffff"
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="schemas.android.com/apk/res/android">;
<gradient
android:type="radial"
android:startColor="#343030"
android:endColor="#151515"
android:gradientRadius="300"
android:angle="270"
android:centerY="0.3"/>
</shape>
Instead of making custom drawable for divider you can directly give color to divider.

Multi color Stroke image with XML

Does it possible to create multi-color stroke with the help of XML? I want to create exact view attached here.
Thanks
You could use a trick by creating a drawable shape with gradient and make it a parent's background... something like this:
gradient_stroke.xml (in res/drawable):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle" >
<gradient
android:angle="180"
android:startColor="#fff96200"
android:centerColor="#fffff60f"
android:endColor="#fff96200"
android:centerX="50%"
>
</gradient>
<corners android:radius="5dp"></corners>
</shape>
</item>
your_view.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:padding="2dp"
android:background="#drawable/gradient_stroke"
android:layout_height="wrap_content">
<Button android:text="Submit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/green"
android:id="#+id/button"/>
</LinearLayout>
Just an idea - play around with it to get desired values...
