public class MainActivity extends AppCompatActivity {
    ListView listView;
    SwipeRefreshLayout swipeRefreshLayout;
    ArrayList<String> list;
    ArrayAdapter<String> arrayAdapter;

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

        list=new ArrayList<>();
        list.add("aaaaa");
        swipeRefreshLayout= (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
        //刷新条变颜色
        swipeRefreshLayout.setColorSchemeResources(android.R.color.holo_blue_bright,android.R.color.holo_green_dark,
                android.R.color.black,android.R.color.holo_orange_dark);

        arrayAdapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,list);
        listView.setAdapter(arrayAdapter);

        //下拉监听
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                list.add(0,"oooo");
                arrayAdapter.notifyDataSetChanged();        //刷新
                swipeRefreshLayout.setRefreshing(false);    //停止刷新
            }
        });
    }
