dynamically add remove control form linearlayout

Question

I have 3 layouts, I need when click on button access certain layout and ad remove controls from and in it any idea how to achieve that , this is the code I use

Answer 1

Add andoird:id="@+id/linerlayout_1" after that you can access this view easy inside the code with the findviewbyid() method.

For examlpe: place this inside the button's onclicklistener method.

LinearLayout ll = (LinearLayout) findViewById(R.id.linerlayout);
ll.setVisibility(View.GONE); // this row will hide the entire linerlayout
ll.addView(someView); //this row will add the specified View f.e.: TextView
ll.removeView(otherView); // this row will remove the view

And you can manage th view visibility by xml attribute android:visibility too.
