I have TextView added Programmatically in to LinearLayout and on some external events I want to decrease bottom margin of that TextView to -10, for that I tried following.
LinearLayout.LayoutParams lastTxtParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); lastTxtParams.setMargins(0, 0, 0, -10); mOldTextView.setLayoutParams(lastTxtParams); mOldTextView.invalidate();
Is the right way of modifying Margin of widget that has been added to View?
Some how it is not working.
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.
