LinearLayout ll = findViewById(R.id.yourLinearLayout);

To remove any view you can use

ll.removeView(view)// to remove particular view
ll.removeViewAt(position);// to remove view from particular position

Use following logic to remove any view from layout

ll.post(new Runnable() {
    public void run() {
        ll.removeView(view);
    }
});

Simply Use linearLayout.removeView(View view); It would refresh automaically.

use listview with Adapter to fill the data dynamically (because that's what for they are made) and whenever your data or UI gets changed create new adapter (data set) and notify the adapter about change.

By removing or adding views the linearlayout has to measure and layout all its children again which is why they move. You could simply try setting the visibility to invisible.

myLinearLayout.setVisibility(View.INVISIBLE);

any view set to invisible still retains its size and positioning in the layout but can no longer be seen.

You question is not that clear. But you could try setting the view as visibility = gone.
