Answer 1

Since you are using android's array adapter, you can use its getFilter() method too. So you just have to change minor things in your code.

Instead of setting array adapter like this

list1.setAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1, array));

Create a private variable outside of the methods

private ArrayAdapter adapter;

Then initialize and set it

adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1, array);
list1.setAdapter(adapter);

Now text changed method can call MainActivity.this.adapter.getFilter().filter(cs); without any problem
