SwipeRefreshLayout的功能就是可以让我们的界面在不动的情况下,下拉直接刷新

废话不多说,效果图奉上:

activity_listview布局文件

<android.support.v4.widget.SwipeRefreshLayout android:id="@+id/sr1" android:layout_width="match_parent" android:layout_height="match_parent"> <ListView android:id="@+id/lv" android:layout_width="match_parent" android:layout_height="wrap_content"/> </android.support.v4.widget.SwipeRefreshLayout>

Activity代码(ListViewActivity)

public class ListViewActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener { private SwipeRefreshLayout swipeRefreshLayout; private ListView listView; private List<String> list; private ArrayAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_list_view); swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.sr1); swipeRefreshLayout.setOnRefreshListener(this); list = new ArrayList<>(); list.add("ssss"); listView = (ListView) findViewById(R.id.lv); adapter = new ArrayAdapter(this , android.R.layout.simple_list_item_1 , android.R.id.text1 , list); listView.setAdapter(adapter); } @Override public void onRefresh() { new Handler().postDelayed(new Runnable() { @Override public void run() { swipeRefreshLayout.setRefreshing(false); adapter.clear(); list.add("1111"); adapter.notifyDataSetChanged(); } }, 1000); } }
