Android 如何从上一个Listview中的选定项访问另一个Listview？

我是新手。大家好。我想开发一个应用程序，它首先显示马来西亚的一个州列表，然后当一个州被选中时，另一个显示该州学校名称的列表就会弹出。到目前为止，我已经完成了第一部分。我怎么去第二部分？我做了一些研究，但还是迷路了。非常感谢您的建议、示例和教程链接

public class MainActivity extends Activity {

    //Initialize the array
    String[] states = { "Federal Territory of Kuala Lumpur", "Federal Territory of Labuan", "Federal Territory of Putrajaya", 
                       "Johor", "Kedah", "Kelantan", "Malacca", "Negeri Sembilan", "Pahang", "Perak", "Perlis", "Penang",
                       "Sabah", "Sarawak", "Selangor", "Terengganu" };

    // Declare the UI components
    private ListView statesListView;

    private ArrayAdapter arrayAdapter;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initialize the UI components
        statesListView = (ListView) findViewById(R.id.listview);

        arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, states);

        // By using setAdapter method, you plugged the ListView with adapter
        statesListView.setAdapter(arrayAdapter);
    }

}
