android recyclerview,AndroidRecyclerView中的Item嵌套RecyclerView使用实例

最近项目中有一个需求是RecyclerView中的Item中嵌套RecyclerView，在网上没找到什么资料，然后就自己尝试了一下。

首先看一下效果图

录制GIF现在不大方便，就直接上两个图了。

关于RecyclerView，都已经很熟悉了不熟悉的去百度一下，这里就不多介绍了。

先说一下需求，最外层的是一个RecyclerView是竖向的，然后外层RecyclerView里面Item中的RecyclerView是GridManager。

我们先看一下具体的代码：

最外层的布局代码：

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical">

android:id="@+id/rvMultipleItem"

android:layout_width="match_parent"

android:layout_height="match_parent"/>

public class MultipleActivity extends AppCompatActivity {

private static final String TAG = "MultipleActivity";

RecyclerView mRecyclerView;

TopCategoryBean mCategoryBean = new TopCategoryBean();

MultipleAdapter mMultipleAdapter;

@Override

protected void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_multiple);

mRecyclerView = (RecyclerView) findViewById(R.id.rvMultipleItem);

mMultipleAdapter = new MultipleAdapter(this, mCategoryBean);

mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

new Thread(new Runnable() {

@Override

public void run() {

try {

URL url = new URL("http://api.zhuishushenqi.com/cats/lv2/statistics");

HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

urlConnection.setRequestMethod("GET");

urlConnection.setConnectTimeout(60000);

urlConnection.setConnectTimeout(10000);

int responseCode = urlConnection.getResponseCode();

if (responseCode == 200) {

InputStream inputStream = urlConnection.
