使用SimpleAdapter 适配器时显示网络上图片方法

?SimpleAdapter listItemAdapter = new SimpleAdapter(this, listItem,
????R.layout.items_list,
????new String[] { "imagePath", "name", "njname", "length", "id" },
????new int[] { R.id.imagePath, R.id.name, R.id.njname, R.id.length, R.id.hiddenId });

第一步：设置listItemAdapter
??listItemAdapter.setViewBinder(new CustomViewBinder());

?

第二步：

import android.graphics.Bitmap;
import android.view.View;
import android.widget.ImageView;
import android.widget.SimpleAdapter.ViewBinder;

public class CustomViewBinder implements ViewBinder {
?public boolean setViewValue(View view, Object data, String textRepresentation) {
??if ((view instanceof ImageView) & (data instanceof Bitmap)) {
???ImageView iv = (ImageView) view;
???Bitmap bm = (Bitmap) data;
???iv.setImageBitmap(bm);
???return true;
??}
??return false;
?}
}
