I need to draw a background of layout as a triangle, like you can see in the picture.

I've found an example where they do something similar, but I don't know how to adapt it to my case. Here is the example

Can anyone help me? Best.

Here is an example of a drawable resource with a triangle in the right bottom corner in front of an image. As the image I used the default android launcher icon. You can use any other image.

Create triangle.xml file in res/drawable like this:

android:drawable="@drawable/ic_launcher">

android:fromDegrees="-45"

android:toDegrees="0"

android:pivotX="150%"

android:pivotY="20%" >

android:shape="rectangle" >

Then use it as background attribute of a view:

android:background="@drawable/triangle"
