I want to make a edit note and draw a paper line in background of that. Like the image below (as you can see, either vertical and horizontal line):
I don't know how can I draw it and how can I repeat it?

1If your just drawing lines why can't you use a canvas? – cjds Dec 17 '12 at 11:39

How can I use a canvas? could you tell me a sample from a picture with multi line? – Omid Nazifi Dec 17 '12 at 11:46

It seems like this is a feature that is currently lacking within an ImageView. I suspect you'll need to create your own View class to handle the repeating drawing on your own. – jsmith Dec 17 '12 at 14:13

Here is the answer for your problem https://stackoverflow.com/a/10770670/619673
Of course you can implement it in textview (linked topic is about edittext) but it is quite the same operation (i think :D ).
To use it in your xml you have to write instead of TextView your package path to custom widget class i.e. com.example.notepad.linkededit
Example:
<RelativeLayout 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"
tools:context=".MainActivity" >
<com.example.notepadline.LinedEditText
android:id="@+id/tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:singleLine="false"
android:text="AAAA AAAA AAA AAAA AAAA AAA AAAA AAAA AAA AAAA AAAA AAA AAAA AAAA AAA AAAA AAAA AAA" />
</RelativeLayout>
The rest of information is in reference link.
