Your TextView need to implemented Checkable interface. Try to use Known Indirect Subclasses of Checkable eg. CheckedTextView or implement your own TextView.

Replace the TextView by CheckedTextView then your selector must be as following

   <?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android">
     <item  android:state_checked="true"   android:color="#12fdfd"/>
     <item  android:color="#000"/>
  </selector>

use the setChecked(boolean bln) function for your CheckedTextView

 mCTxtView.setChecked(true);

You can use it as checkbox ui by setting drawable for checkedTextView

android:drawableLeft="@drawable/radio_drawable"

radio_drawable.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:drawable="@drawable/radio_checked"  android:state_checked="true"/>
  <item android:drawable="@drawable/radio_unchecked" />
</selector>

would there be a checkbox in ui with checkedTextView? – Zeeshan Shabbir Mar 19 '16 at 08:58
Yes you can by setting drawable – Ahmed Khamis Mar 19 '16 at 09:01
once mCTxtView.setChecked(true); is set then it will remain true whole time. how would i make it false when other textview would be clicked so only one textview should be checked at a one one – Zeeshan Shabbir Mar 19 '16 at 09:05
you must implement mCTxtView.setOnClickListener(new View.OnClickListener() { } to set others unchecked do you use RecyclerView or ListView ? – Ahmed Khamis Mar 19 '16 at 09:21
that would make my code so long if i go like this. There could be hunderd of static textviews – Zeeshan Shabbir Mar 19 '16 at 09:23
No It wouldn't if you use RecyclerView or ListView – Ahmed Khamis Mar 19 '16 at 09:25
