First of all ensure that listview id in your activity_main.xml equals to "android:id="#android:id/list".
In code change line
setListAdapter(new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1,list));
If you want to manipulate with listView use:
ListView myListView = getListview();
