粉红色部分就是vpopupwindow要使用的,红色的部分一定要添加 不然点击事件不执行。
layout.gridviewpopup 如下:
[code="java<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridviewparent"
android:orientation="horizontal"

android:paddingLeft="10dip"
android:paddingRight="10dip"

这个呢只是图片的一个外边框背景。
ImageAdapter的扩展
引用public class ImageAdapter extends BaseAdapter { private Context mContext; private int itemBackground; public ImageAdapter(Context c) { mContext = c; //---setting the style--- <SPAN style="COLOR: #ffcc00">TypedArray a = c.obtainStyledAttributes(R.styleable.Gallery1); itemBackground = a.getResourceId(R.styleable.Gallery1_android_galleryItemBackground, 0); a.recycle();</SPAN> } public int getCount() { return images.length; } public Object getItem(int position) { //return images[position]; return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { imageView = new ImageView(mContext); } else { imageView = (ImageView) convertView; } imageView.setImageResource(images[position]); imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE); <SPAN style="COLOR: #ffcc00">imageView.setBackgroundResource(itemBackground);</SPAN> return imageView; } public Integer[] images = { R.drawable.android, R.drawable.icon, R.drawable.android }; }
