My java class file:

if(!reccinc.equals("0"))
            {
                System.out.println("Inside if");
            EditText rec=(EditText)findViewById(R.id.reccedit);
            EditText reccdate=(EditText)findViewById(R.id.reccdateedit);
            EditText recctype=(EditText)findViewById(R.id.recccatedit);

            String recc=null;
            String date=null;
            String type=null;
            db.open();               
            if(!intent.getStringExtra("Recc").equals("0"))
            {
                 Cursor c= db.getReccurenceCount(intent.getStringExtra("Recc"));    
                 startManagingCursor(c);
                 recc=c.getString(c.getColumnIndex("increment"));
                 date=c.getString(c.getColumnIndex("startdate"));
                 type=c.getString(c.getColumnIndex("recurrencetype"));
            }

            rec.setText(recc);
            recctype.setText(type);
            reccdate.setText(date);
            }

Answer 1

You can call

view.setVisibility(View.GONE);

to make a view disappear from a layout. You can call

view.setVisibility(View.VISIBLE);

to bring it back again (assuming it has not been removed from the layout).
