Code for MainActivity.java file.

public class MainActivity extends Activity {

    ListView listview;
    Button Addbutton;
    EditText GetValue;
    String[] ListElements = new String[] {
        "Android",
        "PHP"
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listview = (ListView) findViewById(R.id.listView1);
        Addbutton = (Button) findViewById(R.id.button1);
        GetValue = (EditText) findViewById(R.id.editText1);

        final List < String > ListElementsArrayList = new ArrayList < String >
            (Arrays.asList(ListElements));


        final ArrayAdapter < String > adapter = new ArrayAdapter < String >
            (MainActivity.this, android.R.layout.simple_list_item_1,
                ListElementsArrayList);

        listview.setAdapter(adapter);

        Addbutton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                ListElementsArrayList.add(GetValue.getText().toString());
                adapter.notifyDataSetChanged();
            }
        });
    }
