GridView在ScrollView中实现在家更多

这个本身会有bug  应该在滑动监听中作出判断的

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">    <ScrollView        android:id="@+id/s"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:fillViewport="false"        android:scrollbars="none">         <LinearLayout             android:layout_width="match_parent"             android:layout_height="match_parent"             android:orientation="vertical">            <TextView                android:id="@+id/love"                android:layout_width="match_parent"                android:layout_height="100dp"                android:background="#fffccc"                android:text="caini xihuan " />             <com.maoyudun.alimamaproject.widget.MyGridView                 android:id="@+id/fourth_GridView"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:background="#f4f5f9"                 android:horizontalSpacing="10px"                 android:numColumns="2"                 android:verticalSpacing="10px" />             <LinearLayout                 android:id="@+id/loadmore"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:gravity="center"                 android:visibility="gone">                 <ProgressBar                     android:id="@+id/pb_progress"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:layout_gravity="center"                     android:indeterminateDrawable="@drawable/custom_progress" />                 <TextView                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:layout_gravity="center_vertical"                     android:layout_marginLeft="5dp"                     android:text="正在加载..."                     android:textColor="@android:color/black"                     android:textSize="20dp"                     android:visibility="visible" />             </LinearLayout>        </LinearLayout>    </ScrollView></RelativeLayout>  

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 onLoadMoreListener(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
