Current Time:

                txtCurrentTime= (TextView)findViewById(R.id.txtcurrunt);
                Date dt = new Date();
                int hours = dt.getHours();
                int minutes = dt.getMinutes();
                int seconds = dt.getSeconds();
                String curTime = hours + ":" + minutes + ":" + seconds;
                txtCurrentTime.setText(curTime);

User Input:

                userInput=(EditText)findViewById(R.id.userInputInSeconds);
                String userInput=userInput.getText().toString();
                long increment=Long.parseLong(userInput);
//New Time
              Date dt = new Date();
              long newTime =dt.getTime()+(increment)/1000;
              Date newData=new Date(newTime);
              int hours = newData.getHours();
              int minutes = newData.getMinutes();
              int seconds = newData.getSeconds();
              String newTimeString = hours + ":" + minutes + ":" + seconds;

              txtNewTime= (TextView)findViewById(R.id.txtNew);
              txtNewTime.setText(newTimeString);

I hope it will help you…:)
