TextView forgot_pswrd = (TextView) findViewById(R.id.ForgotPasswordText);
forgot_pswrd.setOnTouchListener(this);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
llp.setMargins(50, 0, 0, 0); // llp.setMargins(left, top, right, bottom);
forgot_pswrd.setLayoutParams(llp);
I did this and it worked perfectly.
Maybe as you are giving the value in -ve, that’s why your code is not working.
You just put this code where you are creating the reference of the view.
