想請問一下listview要怎麼抓www下的圖片 - Android 台灣中文網

try {
String result = DBConnector.executeQuery("我這邊下query");
JSONArray jsonArray = new JSONArray(result);
JSONArray jsonArray = new JSONArray(result);
for(int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonData = jsonArray.getJSONObject(i);
id = jsonData.getString("Name")+ "
";
name = jsonData.getString("Content") + "
";
sum = id+name;
imageFileURL= jsonData.getString("img");
myImageView = (ImageView) findViewById(R.id.ivImage);
//建立一個AsyncTask執行緒進行圖片讀取動作，並帶入圖片連結網址路徑
new AsyncTask<String, Void, Bitmap>() {
@Override
protected Bitmap doInBackground(String... params) {
String url = params[0];
return getBitmapFromURL(url);
}
@Override
protected void onPostExecute(Bitmap result) {
myImageView.setImageBitmap(result);
super.onPostExecute(result);
}
}.execute("http://192.168.1.13/XXXX/img/p01");
memberList.add(new Member(i, R.id.ivImage, sum));
}
} catch(Exception e) {
// Log.e("log_tag", e.toString());
}
}
public int getCount() {
return memberList.size();
}
@Override
public Object getItem(int position) {
return memberList.get(position);
}
@Override
public long getItemId(int position) {
return memberList.get(position).getId();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.listview_item, parent, false);
}
Member member = memberList.get(position);
myImageView = (ImageView) convertView
.findViewById(R.id.ivImage);
myImageView.setImageResource(member.getImage());
TextView tvId = (TextView) convertView
.findViewById(R.id.tvId);
tvId.setText(String.valueOf(member.getId()));
TextView tvName = (TextView) convertView
.findViewById(R.id.tvName);
tvName.setText(member.getName());
return convertView;
}
}
private static Bitmap getBitmapFromURL(String imageUrl)
