I want to know, How to write Multiline Text on Button
For Android layout, multiple lines of text could be added to the elements.
Create a new variable with the character endOfLine "\n" in the res/values/strings.xml.
For example:
<string name="multiplelines">Line1 \n Line2</string>
Refer it in the layout file. For example,
<Button
android:id="@+id/start"
android:text="@string/multiplelines"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
</Button>
The solution that can be used in strings.xml, the separator is \n within CDATA
<string name="switch_on_bluetooth"><![CDATA[Allumer\nBluetooth]]></string>
