To click on a piece of the text  not the whole TextView   you can use Html or Linkify  both create links that open urls  though  not a callback in the app    Linkify  Use a string resource like    lt string name  links  gt Here is a link  http   www stackoverflow com lt  string gt    Then in a textview   TextView textView       textView setText R string links   Linkify addLinks textView  Linkify ALL     Html  Using Html fromHtml    lt string name  html  gt Here you can put html  amp lt a href  http   www stackoverflow com  amp gt Link  amp lt   amp gt  lt  string gt    Then in your textview   textView setText Html fromHtml getString R string html

You can set the click handler in xml with these attribute   android onClick  onClick  android clickable  true    Don t forget the clickable attribute  without it  the click handler isn t called     main xml                 lt TextView         android id    id click         android layout width  wrap content         android layout height  wrap content                        android text  Click Me         android textSize  55sp         android onClick  onClick                         android clickable  true   gt            MyActivity java           public class MyActivity extends Activity              public void onClick View v

You can use TextWatcher for TextView  is more flexible than ClickLinstener  not best or worse  only more one way    holder bt foo ex addTextChangedListener new TextWatcher               Override         public void onTextChanged CharSequence s  int start  int before  int count                   code during                       Override         public void beforeTextChanged CharSequence s  int start  int count  int after                   code before                       Override         public void afterTextChanged Editable s                   code after

from inside an activity that calls a layout and a textview  this click listener works   setContentView R layout your layout   TextView tvGmail    TextView  findViewById R id tvGmail   String TAG    yourLogCatTag   tvGmail setOnClickListener new OnClickListener                  Override             public void onClick View viewIn                    try                       Log d TAG  GMAIL account selected                      catch  Exception except                        Log e TAG  Ooops GMAIL account selection problem   except getMessage                                                   the text view is declared like this  default wizard             lt TextView             android id    id tvGmail              android layout width  fill parent              android layout height  wrap content              android text   string menu id google              android textSize  30sp    gt    and in the strings xml file   lt string name  menu id google  gt Google ID  Gmail  lt  string gt

Although you can resolve the problem by setting the listener to textview  it s recommended not to  You should use flat button as it is a subclass of Button and it provides many attributes which TextView doesn t     To use flat button  add style   android attr borderlessButtonStyle  attribute -   lt Button     android layout width  wrap content      android layout height  wrap content      android text  DONE      style   android attr borderlessButtonStyle   gt
