I've done it like so:

((ViewManager)entry.getParent()).removeView(entry);

ViewGroup extends View implements ViewParent, ViewManager. nicer to call it with casting to (ViewGroup) – Mercury Apr 25 '17 at 21:30

Use ViewStub and specify the layout of the view you want to toggle. To view:

mViewStub.setVisibility(View.VISIBLE) or mViewStub.inflate();

To disappear:

mViewStub.setVisibility(View.GONE);

Hiding is not the same as removing. – Darkwater Jan 26 '15 at 21:39
If you want to hide/unhide you could use .setVisibility(View.INVISIBLE) and .setVisibility(View.VISIBLE). When the view is invisible the user can't interact with it. – Dennis van der Schagt Aug 28 '15 at 19:07
Let's say I have a textView with an onClickListener attached to it. If I make it disappear and then I tap on it, will the event still fire? – ahitt6345 Aug 04 '16 at 19:47

This is the best way

LinearLayout lp = new LinearLayout(this);
lp.addView(new Button(this));
lp.addView(new ImageButton(this));
// Now remove them 
lp.removeViewAt(0); // and so on

If you have xml layout then no need to add dynamically.just call

lp.removeViewAt(0);

What will be the diff in terms of performance? I mean the performance diff of adding them dynamically or putting them into a static xml layout file and let it be inflated ? – stdout Jun 15 '16 at 13:24

To add view to a layout, you can use addView method of the ViewGroup class. For example,

TextView view = new TextView(getActivity());
view.setText("Hello World");

ViewGroup Layout = (LinearLayout) getActivity().findViewById(R.id.my_layout);
layout.addView(view);

There are also a number of remove methods. Check the documentation of ViewGroup. One simple way to remove view from a layout can be like,

layout.removeAllViews(); // then you will end up having a clean fresh layout

removeAllViews() is what I was looking for! – Alan May 26 '13 at 17:41 — Alan, May 26 '13 at 17:41

Great anwser from Sameer and Abel Terefe. However, when you remove a view, in my option, you want to remove a view with certain id. Here is how do you do that.

1, give the view an id when you create it:

_textView.setId(index);

2, remove the view with the id:

removeView(findViewById(index));

For changing visibility:

predictbtn.setVisibility(View.INVISIBLE);

For removing:

predictbtn.setVisibility(View.GONE);

It fixed my problem, more than every other answer. Useful if like me, your background or some params prevent the view to disappear totally. – Virthuss Oct 07 '15 at 01:50

it is because View.GONE don't remove the view for the layout, only make it invisible, and it doesn't take any space for layout purposes. – Victor Mar 23 '16 at 15:28

you can use addView or removeView

java:

// Root Layout
LinearLayout linearLayout = new LinearLayout(context);
linearLayout.setGravity(Gravity.CENTER);
linearLayout.setOrientation(LinearLayout.VERTICAL);

// TextView
TextView textView = new TextView(context);
textView.setText("Sample");

// Add TextView in LinearLayout
linearLayout.addView(textView);

// Remove TextView from LinearLayout
linearLayout.removeView(textView);

kotlin:

// Root Layout
val linearLayout = LinearLayout(context)
linearLayout.gravity = Gravity.CENTER
linearLayout.orientation = LinearLayout.VERTICAL

// TextView
val textView = TextView(context)
textView.text = "Sample"

// Add TextView in LinearLayout
linearLayout.addView(textView)

// Remove TextView from LinearLayout
linearLayout.removeView(textView)

Kotlin Reusable Extension Solution

Simplify removal

Add this extension:

myView.removeSelf()

fun View?.removeSelf() {
    this ?: return
    val parent = parent as? ViewGroup ?: return
    parent.removeView(this)
}

Simplify addition

Here are a few options:

// Built-in
myViewGroup.addView(myView)

// Null-safe extension
fun ViewGroup?.addView(view: View?) {
    this ?: return
    view ?: return
    addView(view)
}

// Reverse addition
myView.addTo(myViewGroup)

fun View?.addTo(parent: ViewGroup?) {
    this ?: return
    parent ?: return
    parent.addView(this)
}

hi if are you new in android use this way Apply your view to make it gone GONE is one way, else, get hold of the parent view, and remove the child from there..... else get the parent layout and use this method an remove all child parentView.remove(child)

I would suggest using the GONE approach...

GONE will effectively hide the view but it won't remove it from the layout – Sababado Nov 28 '12 at 16:38

Simple use the parentView.remove(removeViewName); – Zala Janaksinh Nov 29 '12 at 04:26
You're right about that, but I was trying to hint that you weren't answering the question by providing the "GONE" solution. – Sababado Nov 29 '12 at 15:20
