上面这个是左右上下联动滑动列表效果，其实就是左边一个列表可以上下滑动，右边一个列表可以上下左右滑动，然后再将左边列表和右边列表关联起来。
这里上下滑动用的是ListView和ScrollView，左右滑动用的是ListView和HorizontalScrollView，ListView和ScrollView及HorizontalScrollView会有冲突，首先要解决它们之间的冲突，ListView和ScrollView一起使用会造成ListView显示不全，可以自定义ListView重写它的onMeasure方法，也可以计算ListView条目的总高度，将总高度设值给ListView，这里采用的是计算ListView条目的总高度，不过需要注意的是ListView条目的总高度这个方法在父布局是LinearLayout的时候才会有效；ListView和HorizontalScrollView冲突解决是自定义HorizontalScrollView的方式；
public class SyncHorizontalScrollView extends HorizontalScrollView {
private View mView;
public SyncHorizontalScrollView(Context context) {
super(context);
}
public SyncHorizontalScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public SyncHorizontalScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
super.onScrollChanged(l, t, oldl, oldt);
if(mView!=null) {
mView.scrollTo(l, t);
}
}
/**
*
* @param view
*/
public void setScrollView(View view) {
mView = view;
}
}
接着去布局里面将控件摆放好，并给对应的列表设置适配器；
