RecyclerView 出现以后 很受大家欢迎 漂亮流畅的列表 简单的操作 可以帮我们完成很多的列表 但是有一种listview 嵌套gridview 的效果 目前还是需要嵌套才能完成 现在就简单说一下我的思路 本人的需求是例如手机淘宝页 本人使用老套的实现模式 Scrollview+recyclerView+gridview 实现 重写gridview 屏蔽recyclerview 滑动 利用Scrollview 进行刷新
下面上代码
<com.handmark.pulltorefresh.library.PullToRefreshScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:id="@+id/test_refreush">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="@+id/tttt_1"
android:layout_width="match_parent"
android:layout_height="300dp" />
<android.support.v7.widget.RecyclerView
android:layout_below="@+id/tttt_1"
android:id="@+id/atest_list"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</RelativeLayout></com.handmark.pulltorefresh.library.PullToRefreshScrollView>
// activity
private RecyclerView atest_list;
private String auuid;
private String aappid;
private String aes;
private List<ATestBean.DataBean> mData = new ArrayList<>();
private MyTestAdapter adapter;
private PullToRefreshScrollView test_refreush;
private int no = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_atest);
atest_list = (RecyclerView) findViewById(R.id.atest_list);
test_refreush = (PullToRefreshScrollView) findViewById(R.id.test_refreush);
atest_list.setHasFixedSize(true);
atest_list.setNestedScrollingEnabled(false);
findViewById(R.id.rl_back).setOnClickListener(this);
LinearLayoutManager manager = new LinearLayoutManager(context,LinearLayoutManager.VERTICAL,false);
atest_list.setLayoutManager(manager);
adapter = new MyTestAdapter(context,mData);
atest_list.setAdapter(adapter);
test_refreush.setMode(PullToRefreshBase.Mode.BOTH);
test_refreush.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener2<ScrollView>() {
@Override
public void onPullDownToRefresh(PullToRefreshBase<ScrollView> refreshView) {
no++;
getShopList(no);
}@Override public void onPullUpToRefresh(PullToRefreshBase<ScrollView> refreshView) { no++; getShopList(no); } }); getShopList(no); } //解析数据 Gson gson = new Gson();
ATestBean testBean = gson.fromJson(data, ATestBean.class);
mData.addAll(testBean.getData());
adapter.notifyDataSetChanged();
if (test_refreush!=null&&test_refreush.isRefreshing()){
test_refreush.onRefreshComplete();
}
