Scrollview嵌套RecyclerView

这个嵌套形式挺常见的，网上有好些解决办法，但我用着不是很好，就自己试了试，有一些注意的地方：
A…Scrollview的唯一子view必须是RelativeLayout，为什么用线性布局不行，我也不是很清楚，可能和布局绘制渲染有关系吧
B…Scrollview必须自定义，不然滑动会黏住，没有惯性滑动，尴尬症会犯的.
C…demo在最下面，这里只是贴了下代码，说一下注意的地方.

1.首先compile下需要的组件，放build.gradle(Module:app),

// Recyclerviewcompile 'com.android.support:recyclerview-v7:25.3.1'//代替findviewbyid的好东西compile 'com.jakewharton:butterknife:7.0.1'

然后sync new

2.activity_main.xml
这里的一个注意的地方，Scrollview的唯一子view必须是RelativeLayout

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"                android:layout_width="match_parent"                android:layout_height="match_parent">    <!--自定义的scrollview，解决滑动惯性冲突，否则会滑动黏住，没有惯性-->    <com.zhb.scrollviewrecyclerview.MyScrollview        android:layout_width="match_parent"        android:layout_height="match_parent">        <!--这里必须是RelativeLayout-->        <RelativeLayout            android:background="#FFFFFF"            android:layout_width="match_parent"            android:layout_height="wrap_content">            <RelativeLayout                android:background="@color/colorPrimary"                android:id="@+id/re"                android:layout_width="match_parent"                android:layout_height="200dp">            </RelativeLayout>            <android.support.v7.widget.RecyclerView                android:id="@+id/bb"                android:layout_below="@id/re"                android:layout_width="wrap_content"                android:layout_height="wrap_content">            </android.support.v7.widget.RecyclerView>        </RelativeLayout>    </com.zhb.scrollviewrecyclerview.MyScrollview></RelativeLayout>

3.MainActivity
这里butterknife组件的使用自己百度吧，挺好用的，不会就findviewbyid

package com.zhb.scrollviewrecyclerview;import android.app.Activity;import android.os.Bundle;import android.support.v7.widget.DefaultItemAnimator;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import android.widget.RelativeLayout;import java.util.ArrayList;import butterknife.Bind;import butterknife.ButterKnife;public class MainActivity extends Activity{    ArrayList<String> datas = new ArrayList<>();    @Bind (R.id.re)    RelativeLayout re;    @Bind (R.id.bb)    RecyclerView bb;    NormalRecyclerViewAdapter normalRecyclerViewAdapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        //设置RecyclerView        normalRecyclerViewAdapter = new NormalRecyclerViewAdapter(this, datas);        bb.setLayoutManager(new LinearLayoutManager(this));        bb.setAdapter(normalRecyclerViewAdapter);        //设置Item增加、移除动画        bb.setItemAnimator(new DefaultItemAnimator());        //模拟加载数据，一般需要从后台获取的        for(int i = 0; i < 50; i++) {            datas.add("" + i);        }        normalRecyclerViewAdapter.setList(datas);    }}

4.适配器NormalRecyclerViewAdapter

package com.zhb.scrollviewrecyclerview;import android.content.Context;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.TextView;import java.util.ArrayList;/** * Created by zhb on 2016/9/13. */public class NormalRecyclerViewAdapter extends RecyclerView.Adapter<NormalRecyclerViewAdapter.NormalTextViewHolder> {    private final LayoutInflater mLayoutInflater;    private final Context mContext;    ArrayList<String> datas = new ArrayList<String>();    public NormalRecyclerViewAdapter(Context context, ArrayList<String> datas) {        this.datas = datas;        this.mContext = context;        mLayoutInflater = LayoutInflater.from(context);    }    @Override    public NormalTextViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        return new NormalTextViewHolder(mLayoutInflater.inflate(R.layout.item_text, parent, false));    }    @Override    public void onBindViewHolder(NormalTextViewHolder holder, int position) {        holder.mTextView.setText(position + "");    }    public void setList(ArrayList<String> datas){        this.datas = datas;        notifyDataSetChanged();    }    @Override    public int getItemCount() {        return datas.size();    }    public static class NormalTextViewHolder extends RecyclerView.ViewHolder {        TextView mTextView;        NormalTextViewHolder(View view) {            super(view);            mTextView = (TextView) view.findViewById(R.id.text_view);        }    }}

5.适配器布局item_text.xml
就简单一个TextView而已，还是贴一下好了。。

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              android:layout_width="match_parent"              android:layout_height="wrap_content">    <TextView        android:background="@color/colorAccent"        android:textColor="#5f5"        android:textSize="15sp"        android:id="@+id/text_view"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        /></LinearLayout>

6.自定义Scrollview，，MyScrollview解决滑动问题

package com.zhb.scrollviewrecyclerview;import android.content.Context;import android.util.AttributeSet;import android.view.MotionEvent;import android.view.ViewConfiguration;import android.widget.ScrollView;/** * Created by zhb on 2017/6/14. * 嵌套recyclerview,滑动惯性问题 */public class MyScrollview extends ScrollView {    private int downX;    private int downY;    private int mTouchSlop;    public MyScrollview(Context context) {        super(context);        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();    }    public MyScrollview(Context context, AttributeSet attrs) {        super(context, attrs);        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();    }    public MyScrollview(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();    }    @Override    public boolean onInterceptTouchEvent(MotionEvent e) {        int action = e.getAction();        switch (action) {            case MotionEvent.ACTION_DOWN:                downX = (int) e.getRawX();                downY = (int) e.getRawY();                break;            case MotionEvent.ACTION_MOVE:                int moveY = (int) e.getRawY();                if (Math.abs(moveY - downY) > mTouchSlop) {                    return true;                }        }        return super.onInterceptTouchEvent(e);    }}
