This is my layout code. I wanted to add a text data from EditText to the ListView which is on same page. How to write a code to add text to the list when I click on the AddValue Button.
Thanks in advance.

Answer 1

use this code

 addbutton.setOnClickListener(new View.OnClickListener() {
      public void onClick(View v) {     
         String val = edittext.getText().toString();
         list.add(val);
         ((ArrayAdapter<Object>) listView.getAdapter()).notifyDataSetChanged();
     }
});
