Android开发笔记之 RecyclerView和ScrollView嵌套使用，ListView和ScrollView嵌套使用对比

直接上代码：

    1、 Activity的代码：

public class MainActivity extends AppCompatActivity {
    private List list;

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

        list = new ArrayList<>();
        for (int i = 0; i < 20; i++) {
            list.add("item:" + i);
        }
            
        ListView listView = findViewById(R.id.listView);
        listView.setAdapter(new MyListViewAdapter(this, list));

        RecyclerView recyclerView = findViewById(R.id.recyclerView);
        recyclerView.setAdapter(new MyAdapter(this, list));
        LinearLayoutManager manager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
        recyclerView.setLayoutManager(manager);

    }
}

    2、Activity中加载的view的布局：

xml version="1.0" encoding="utf-8"?>
xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.wuxia.recyclerviewdemo.MainActivity">

            android:id="@+id/title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:text="嵌套使用滑动view时事件冲突问题" />

            android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/title">

                    android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

                            android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="5dp"
                android:src="@mipmap/ic_launcher" />

                            android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:padding="10dp"
                android:text="山东方后来分开哈里斯发酵方法" />

                            android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="5dp"
                android:src="@mipmap/ic_launcher" />

                            android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:padding="10dp"
                android:text="阿是大陆首发螺蛳粉" />

                            android:id="@+id/listView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:visibility="visible" />

                            android:id="@+id/recyclerView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:visibility="gone" />
        

    

    3、RecyclerView的Adapter：

public class MyRecyclerViewAdapter extends RecyclerView.Adapter {
    private Context context;
    private List list;

    public MyRecyclerViewAdapter(Context context, List list) {
        this.context = context;
        this.list = list;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.item, null);
        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        holder.title.setText(list.get(position));
    }

    @Override
    public int getItemCount() {
        return list.size();
    }

    class MyViewHolder extends RecyclerView.ViewHolder {

        private TextView title;

        public MyViewHolder(View itemView) {
            super(itemView);
            title = itemView.findViewById(R.id.title);
        }
    }
}

    4、运行效果：

结论：6.0模拟器上recyclerview的数据显示完全，并且recyclerview也可以滑动，额、、、模拟器上操作起来稍稍有点卡顿的意思。oppo r9  Android5.1真机上，recyclerview数据显示完全，recyclerview失去滑动能力。

下面演示ScrollView里嵌套使用ListView，Adapter的代码如下：

public class MyListViewAdapter extends BaseAdapter {
    private Context context;
    private List list;

    public MyListViewAdapter(Context context, List list) {
        this.context = context;
        this.list = list;
    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        MyViewHolder myViewHolder = null;
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.item, null);
            myViewHolder = new MyViewHolder();
            convertView.setTag(myViewHolder);
        } else {
            myViewHolder = (MyViewHolder) convertView.getTag();
        }
        myViewHolder.title = (TextView) convertView.findViewById(R.id.title);
        myViewHolder.title.setText(list.get(position));

        return convertView;
    }

    class MyViewHolder {
        TextView title;
    }
}

接下来在布局文件中设置RecyclerView隐藏，ListView设置为显示，运行效果如下：

结论：6.0模拟器上ListView数据显示不全，ListView可以滑动，oppo r9  Android5.1真机上，ListView数据显示不全，ListView可以滑动。
