You can use the  android hint  attribute in your EditText also from code   editText setHint CharSequence hint   int resid     Then you don t need any onClickListener or similar  But consider that the hint value won t be passed  The editText will be stayed empty  In this case you can set your editText with your deflault value   if editText getText   toString   equals            use your default value instead of the editText

It s simple  declare the widget variables  editText  textView  button etc   in class but initialize it in onCreate after setContentView   The problem is when you try to access a widget of a layout first you have to declare the layout  Declaring the layout is setContentView   And when you initialize the widget variable via findViewById you are accessing the id of the widget in the main layout in the setContentView    I hope you get it

First you need to call setContentView R layout main  then all other initialization   Please try below Code   public class Trackfolio extends Activity implements OnClickListener           Called when the activity is first created         public EditText editText        Override     public void onCreate Bundle savedInstanceState            super onCreate savedInstanceState            setContentView R layout main            editText    EditText  findViewById R id editText1           editText setOnClickListener this               Override     public void onClick View v            editText getText   clear      or you can use editText setText
