Dynamically adding widgets to a User interface

Normally the views defined using the XML layout field can be simply inflated by using the setContetntView(R.layout.main).

The following code is used to add a button dynamically:

public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);

   //Inflate the layout file res\layout\activity_uc.xml

   LinearLayout layout = (LinearLayout)getLayoutInflater().inflate(R.layout.main,null);

   //Initiate a new button

   Button reset = new Button(this);
   reset.setText("Reset Form");

   //Add the new button to the layout

   layout.addView(reset,new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,

   LayoutParams.WRAP_CONTENT));

   //Attach the view to the window

   setContentView(layout);

}
