protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CustomTextView customTextView = (CustomTextView) findViewById(R.id.pager_title);
}
}

</RelativeLayout>
attars:

Programmatically usage:
CustomTextView mtxt_name = (CustomTextView) findViewById(R.id.pager_title);
//then use
setStroke(float width, int color, Paint.Join join, float miter);
//method before setting
setText("Sample Text");
