2014.04.22 ——— android listview header和左右滑动冲突

有的时候，listview的好hearder会展示焦点图，这些图是可以左右滑动的，但是可能整个listview也可以左右切换到其他fragment里面，这个时候就会有冲突了，解决：

public class HotListView extends ListView {    private boolean mHeaderViewsScrollable = true;    public HotListView(Context context) {        super(context);    }    public HotListView(Context context, AttributeSet attrs) {        super(context, attrs);    }    public HotListView(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);    }    public void setHeaderViewsScrollable(boolean scrollable) {        mHeaderViewsScrollable = scrollable;    }    @Override    public boolean onInterceptTouchEvent(MotionEvent ev) {        return !(!mHeaderViewsScrollable && isInHeaderView(ev)) && super.onInterceptTouchEvent(ev);    }    private boolean isInHeaderView(MotionEvent ev) {        boolean result = false;        int lastHeaderViewPosition = getHeaderViewsCount() - 1;        int firstVisiblePosition = getFirstVisiblePosition();        int lastVisiblePosition = getLastVisiblePosition();        if (firstVisiblePosition <= lastHeaderViewPosition) {            if (lastHeaderViewPosition <= lastVisiblePosition) {                View lastHeaderView = getChildAt(lastHeaderViewPosition - firstVisiblePosition);                result = ev.getY() < lastHeaderView.getBottom();            } else {                result = true;            }        }        return result;    }}
