Android 屏蔽ScrollView滑动操作
屏蔽ScrollView滑动操作，如下，会用到ViewConfiguration这个类，这个类可以获取到用户是否为滑动操作的临界值。
代码如下：
package com.xx.uikit.view;
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewConfiguration;
import android.widget.ScrollView;
/**

*/
public class RecyclerScrollview extends ScrollView {
private int downY;
private int mTouchSlop;
public RecyclerScrollview(Context context) {
super(context);
mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
}
public RecyclerScrollview(Context context, AttributeSet attrs) {
super(context, attrs);
mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
}
public RecyclerScrollview(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:
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);
}
}
