You can easily add a View with the height of 1dp aligning start and the end of TextView  right below it  You can also use marginTop with negative value to make the underline closer to TextView  If you use your TextView and the under inside a relative layout  it would be much easier for alignments  here is the example    lt RelativeLayout android layout width  match parent  android layout height  wrap content  gt    lt View   android id    id viewForgotPasswordUnderline    android layout width  wrap content    android layout height  1dp    android layout below   id txtForgotPassword    android layout alignStart   id txtForgotPassword    android layout alignEnd   id txtForgotPassword    android layout marginTop  -2dp    android background   color lightGray    gt    lt androidx appcompat widget AppCompatTextView   android id    id txtForgotPassword    android layout width  wrap content    android layout height  wrap content    android layout centerHorizontal  true    android paddingTop  8dp    android text   string userLoginForgotPassword    android textColor   color lightGray    android textSize  16dp    gt   lt  RelativeLayout gt

Android supports string formatting using HTML tags in the strings xml  So the following would work     lt string name  label testinghtmltags  gt  lt u gt This text has an underscore lt  u gt  lt  string gt    Then you just use it as you normally would  You can see more in the documentation here  Update   To further expand on the answer  the documentation says          the format String  Object     and getString int  Object     methods strip all the style information from the string    The work-around to this is to write the HTML tags with escaped entities  which are then recovered with fromHtml String   after the formatting takes place   For example  the resulting string from the following code snippet will not show up as containing underscored elements    lt string name  html bold test  gt This  lt u gt  1 s lt  u gt  has an underscore lt  string gt  String result   getString R string html bold test   text     However the result from the following snippet would contain underscores    lt string name  html bold test  gt This  amp lt u gt   1 s  amp lt  u gt  has an underscore lt  string gt  String result   Html fromHtml getString R string html bold test   text

Simple and easy way to display underline in TextView is     yourTextView getPaint   setUnderlineText true     And if you want to remove underlining for that view  you can write below code      yourTextView getPaint   setUnderlineText false      It will work even though you set android textAllCaps  true
