我是靠谱客的博主复杂电话，最近开发中收集的这篇文章主要介绍Android ScrollView 嵌套 ScrollView 滑动，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

滑动问题就是解决事件的分发问题
MainActivity不需要任何代码，直接在布局中使用就可以了。

1：相配合的自定义布局，onInterceptTouchEvent MotionEvent.ACTION_DOWN情况下拦截情况

package com.example.test.scrollnesttest;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.RelativeLayout;

public class MyRelativelayout extends RelativeLayout {
    public MyRelativelayout(Context context) {
        super(context);
    }

    public MyRelativelayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            return false;
        } else {
            return true;
        }
    }
}

2：自定义MyScroll 嵌套在Scrollview中
需要了解requestDisallowInterceptTouchEvent();
事件是由父view传递到子view 此方法就是提醒父view是否拦截该事件。

package com.example.test.scrollnesttest;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ScrollView;

/**
 * Created by win7 on 2016/9/13.
 */

public class MyScroll extends ScrollView {
    public MyScroll(Context context) {
        super(context);
    }

    public MyScroll(Context context, AttributeSet attrs) {
        super(context, attrs);
    }


    private static final String TAG = "InnerScrollView";
    private int oldY;

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                Log.e(TAG, "ACTION_DOWN: " + ev.getY());
                oldY = (int) ev.getY();
                //提醒父view不要拦截down事件
                getParent().requestDisallowInterceptTouchEvent(true);
                break;
            case MotionEvent.ACTION_MOVE:
                Log.e(TAG, "ACTION_MOVE: " + ev.getY());
                View childView = getChildAt(0);
                Log.e(TAG, "childView.getMeasuredHeight(): " + childView.getMeasuredHeight());
                Log.e(TAG, "getScrollY(): " + getScrollY());
                Log.e(TAG, "getHeight(): " + getHeight());
                if ((getScrollY() == 0 && ev.getY() - oldY > 5) || (childView.getMeasuredHeight() <= getScrollY() + getHeight() && oldY - ev.getY() > 5)) {
                    Log.e(TAG, "ev.getY() - oldY " + (ev.getY() - oldY));
                    //当滑动到最顶端和最底端的时候提醒父view拦截move事件
                    getParent().requestDisallowInterceptTouchEvent(false);
                }
                oldY = (int) ev.getY();
                break;
            case MotionEvent.ACTION_UP:
                break;
        }
        return super.onTouchEvent(ev);
    }

}

布局中直接调用即可
