这个本身会有bug  应该在滑动监听中作出判断的

解决显示不全的问题自定义的GridView

public class MyGridView extends GridView
{
    public MyGridView(Context context) {
        super(context);
    }
    public MyGridView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyGridView(Context context, AttributeSet attrs,
                      int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}
定义接口监听什么时候显示最后一条数据

public interface LoadMoreGridViewListener {
    void loadMore(int position);
}
在adapter中调用接口回传数据

LoadMoreGridViewListener loadmore;
public void onl oadMoreListener(LoadMoreGridViewListener load){
    loadmore=load;
}

/**
 * 判断滑动的位置
 */
if(position==mDatas.size()-1){
    loadmore.loadMore(position);
}
在new adapater使用

void loadMore(int position);接口方法获取最后一个  

adapter.onLoadMoreListener(new LoadMoreGridViewListener() {
    @Override
    public void loadMore(int position) {
        loadmore.animate().translationY(0).setDuration(300).setInterpolator(new AccelerateDecelerateInterpolator())
                .setListener(new Animator.AnimatorListener() {
                    @Override
                    public void onAnimationStart(Animator animation) {
                        loadmore.setVisibility(View.VISIBLE);
                        handler.sendEmptyMessageDelayed(1,5000);

                    }

                    @Override
                    public void onAnimationEnd(Animator animation) {

                    }

                    @Override
                    public void onAnimationCancel(Animator animation) {

                    }

                    @Override
                    public void onAnimationRepeat(Animator animation) {

                    }
                });
    }
});

隐藏加载更多的时候直接GONE

GridView在ScrollView中实现在家更多
