源码：

 @VisibleForTestingNearestTouchFrame(Context context, AttributeSet attrs, Configuration c) {super(context, attrs);mIsActive = c.smallestScreenWidthDp < 600;int[] attrsArray = new int[] {R.attr.isVertical};TypedArray ta = context.obtainStyledAttributes(attrs, attrsArray);mIsVertical = ta.getBoolean(0, false);ta.recycle();}

修改为：

@VisibleForTestingNearestTouchFrame(Context context, AttributeSet attrs, Configuration c) {super(context, attrs);mIsActive = false;int[] attrsArray = new int[] {R.attr.isVertical};TypedArray ta = context.obtainStyledAttributes(attrs, attrsArray);mIsVertical = ta.getBoolean(0, false);ta.recycle();}
