============问题描述============
传输数据（title，imgurl，account）当传输title或title+account时数据正常传输，但是无法传输Imgurl项，即使imgurl+title都一样，没有任何数据显示
请教
1.httpcon.java复制内容到剪贴板代码:
//数据交互，输入输出流与读取流

2.dbUtil.java复制内容到剪贴板代码:
//算是逻辑层吧
import java.sql.Connection;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
public class dbUtil {
private ArrayList<String> arrayList = new ArrayList<String>();
private ArrayList<String> brrayList = new ArrayList<String>();

方法名，参数名，参数值

}}

a[j]="http://10.0.2.2:56041/Web"+crrayList.get(j);//补足路径，imgurl存储的为相对路径
return a;}
}
3.mainactivity.java主要代码
复制内容到剪贴板代码:
//显示网络图片，从dbutil.ava获取imgurl路径
Gallery gallery=(Gallery)findViewById(R.id.gallery);
try {
//设置Gallery的Adapter
gallery.setAdapter(new galleryadapter(this));
gallery.setSelection(0);//设置第一个图标居中
gallery.setSpacing(00);//图标之间的距离
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();}
public class galleryadapter extends BaseAdapter {
private String[] myImageURL = dbUtil_1.tpxw();//imgurl传输正常
//gallery格式
public galleryadapter(Context c){
mContext=c;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return myImageURL.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
} @Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ImageView imageView = new ImageView(this.mContext);
try{
URL aryURI = new URL(myImageURL[position]);
// 打开连接
URLConnection conn = aryURI.openConnection();
conn.connect();
// 转变为 InputStream
InputStream is = conn.getInputStream();
// 将InputStream转变为Bitmap
Bitmap bm = BitmapFactory.decodeStream(is);
// 关闭InputStream
is.close();
//添加图片
imageView.setImageBitmap(bm);
} catch (IOException e)
{
e.printStackTrace();
}
//设置布局参数
imageView.setLayoutParams(new Gallery.LayoutParams(350, 300));
return imageView;
}}
4.ej.java复制内容到剪贴板代码:
//调用dbutil.ava，用listview显示所得Imgurl数据

import android.content.Intent;
public class ej extends Activity {
private TextView stvtitle;
private ListView slv;
private dbUtil dbutil_1;
private SimpleAdapter adapter;
private List<HashMap<String, String>> list;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ejym);
//intent传参，在此未粘出代码，但是传参肯定没问题
String yh = null;
final String ej1 = it.getStringExtra(yh);
stvtitle=(TextView)findViewById(R.id.stvtitle);
slv=(ListView)findViewById(R.id.slv);
stvtitle.setText(ej1);
List<HashMap<String, String>> list1 = new ArrayList<HashMap<String, String>>();
list1.clear();
try{
dbutil_1=new dbUtil();//类的实例化
list1=dbutil_1.ejym(ej1);
System.out.println("0000000"+list1);
adapter = new SimpleAdapter(//adapter填充数据，但是到这儿数据已经为空
list，
R.layout.lv02,
new String[]{"biaoti"},
new int[]{R.id.stv00});
slv.setAdapter(adapter);
int totalHeight = 0;
//获取listview项目总数
i = 0; i < adapter.getCount(); i++) {
View listItem = adapter.getView(i, null, slv);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = slv.getLayoutParams();
params.height = totalHeight + (slv.getDividerHeight() * (slv.getCount() - 1));
slv.setLayoutParams(params); }
catch(Exception e)
{
System.out.println("list1异常");
}}}//在mainactivity中传输正常，在ej.java中数据不显示，根据System.out.println（）提示数据在httpcon.java中中断.在httpcon中初始有数据，到最后输出时数据变为空？？但是同样的Imgurl数据在mainactivity.java中正常显示，而换了其他数据在ej.java显示也没问题？？求教啊！！
//传输数据：Imgurl

============解决方案1============
不敢当，只不过是我这几天刚好也遇到了这个问题，你按照我3楼和7楼所写的修改，程序就能跑起来了。我的已经能正确运行了。
