Android - how to remove linear layout view

Question

In my application, I dynamically add a view to a linear layout. each view consists of one button, if you click on it, then the view will be deleted. How to update the linear layout? because when I delete any view, the position of the position will be changed.

Answer 1

To remove any kind you can use

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

Use the following logic to remove any view from the layout

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

Answer 2

You doubt it is not clear. But you can try to set the view as visibility = gone.

Answer 3

When deleting or adding views, linearlayout needs to measure and compose all of its children again, and that is why they move. You can simply try to set the visibility to invisible.

 myLinearLayout.setVisibility(View.INVISIBLE); 

any view set to invisible retains its size and layout, but can no longer be seen.

Answer 4

You tried

 setContentView(R.layout.main); 

after removal?

use listview with the adapter to dynamically populate the data (due to the fact that it is made), and whenever your data or user interface changes, create a new adapter (data set) and notify the adapter.

Just use linearLayout.removeView (View view); It will be automatically updated.
