The toggle button does not display the text ON and OFF on Android

Question

I create a switch button programmatically. The problem is that the button does not display the text ON / OFF . This is the creation code:

  final RelativeLayout.LayoutParams ll = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); ll.addRule(RelativeLayout.ALIGN_PARENT_RIGHT); sw.setLayoutParams(ll); sw.setTextOn(values[0].getName()); sw.setTextOff(values[1].getName()); values[0].getName() returns "OK", and values[1].getName() returns "NOK" 

What could be?

Thanks Jaime

Answer 1

You can do it through XML

 <Switch ... android:showText="true" /> 

Or programmatically as

 mSwitch.setShowText(true); 

Answer 2

Here is the answer from the Android API. You must specify the switch so that it can show shortcuts at all!

public void setShowText (boolean showText) Added to API level 21

Sets whether to turn on / off text.

Related XML Attributes:

 android:showText 

Parameters showText true to display text on / off
