                          int x=Integer.parseInt(lEditText.getText().toString());

                          tv.setText(x);

Answer 1

Try to make changes as below to set the text in your TextView

 int x=Integer.parseInt(lEditText.getText().toString());
   tv.setText(x+""); <-- Add "" to set the integer value in your textview.

EDITED:

Try out below code for your dynamically adding values:

   final EditText et1=(EditText)findViewById(R.id.editText1);
   final EditText et2=(EditText)findViewById(R.id.editText3);
    Button bt=(Button)findViewById(R.id.button1);
    bt.setOnClickListener(new OnClickListener() {           
        @Override
        public void onClick(View arg0) {
            try
            {
            int x=Integer.valueOf(et1.getText().toString());
            int y= Integer.valueOf(et2.getText().toString());
            int z=x+y;
            System.err.println(z+"");
                    tv.setText(z+""); 
            }
            catch (NumberFormatException e) {
                // TODO: handle exception
            }
        }
    });
