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
