Android ScrollView 嵌套 ScrollView 滑动

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
