how to make multi color gradient in xml for android background?

how to make a gradient color background like this in xml android?
Can we make like this background in android?

The image you provide is not a gradient it's normal image but to make gradient in android you can do this:
1- create new drawable resource file
2-change selector to shape
3- inside shape u can start creating your gradient like this:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:type="linear"
android:angle="90"
android:startColor="#f6ee19"
android:endColor="#115ede" />
</shape>

MPAndoid Chart with following styling

I am using MPAndroid Chart for my project.
I want to make the styling of LineChart as follows. Basically I want all 4 Quadrants and other styling like gradient colors etc.

First make it to fill color behind line by doing this:
dataset.setDrawFilled(true);
After that you have to give gradient for that you have make an xml file like that in drawables as gradient_chart_color:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="90"
android:startColor="#FFF300"
android:endColor="#F5F094" />
</shape>
After that you have to do this :
Drawable drawable = ContextCompat.getDrawable(this, R.drawable.fade_red);
dataset.setFillDrawable(drawable);

How to create a rectangle shape with 2 sides in android

I want to show edit text box with two sides. so, for that i need to create a rectangle shape with two sides. PLease help some one.

create a drawable under drawable folder and add the belwow contents (border.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<solid android:color="#color/black" />
<stroke android:width="1dip" android:color="#color/white"/>
</shape>
Now set the Background of the EditText to this draw able like :
android:background="#drawable/border"

I think the best way to do this is to create a 9-patch in PhotoShop with required border sides... there are also several other ways... depends on your design.

How to get more control over gradients

I have the following drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#2F2F2F"
android:endColor="#5A5A5A"
android:angle="90"
android:dither="true"
/>
</shape>
Is there anyway to start the startColor at 50% or the endColor at 50%?
Are there any links that show me all of the attributes I can apply to a gradient?

These pages show all the attributes you can apply to a gradient.

To do something in the middle like you are asking, try experimenting with the android:centerColor attribute.

Are you talking about transparency? I'm fairly certain you can just use a 8-digit color code rather than a 6-digit, the first 2 of which constitute the alpha value. So #AARRGGBB, or something like #882F2F2F.
