코드 다음에 Update Adapter를 시도합니다. 코드는 정상적으로 완료되었습니다. 그러나 모바일은 Hong 모드로 전환됩니다. 루프가 끝난 후. 데이터가 표시됩니다.update adapter에 runOnUiThread를 사용하는 방법
(MainActivity.this).runOnUiThread(new Runnable() {
@Override
public void run() {
for(News news : SharedVar.getCurrentNews()){
_adapter.notifyDataSetChanged();
int currentIndex=news.getIndex();
Log.d("SRC_IMAGE_ADDRESS", news.getImageNewsAddress());
News replaceNews=new News();
News oldNews =_adapter.getItem(currentIndex);
replaceNews.setTitle(oldNews.getTitle()+" ("+String.valueOf(currentIndex)+")");
replaceNews.setImageNews(Helpers.GetImageFromUrl(news.getImageNewsAddress()));
SharedVar.getCurrentNews().set(currentIndex, replaceNews);
_adapter.notifyDataSetChanged();
}
}
});
업데이트 :
는 다음 코드처럼 내 코드를 변경했습니다. Hong 모드가 여전히 해결되지 않았습니다. 어떻게 수정합니까?
(MainActivity.this).runOnUiThread(new Runnable() {
@Override
public void run() {
for(News news : SharedVar.getCurrentNews()){
int currentIndex=news.getIndex();
Log.d("SRC_IMAGE_ADDRESS", news.getImageNewsAddress());
News replaceNews=new News();
News oldNews =_adapter.getItem(currentIndex);
replaceNews.setTitle(oldNews.getTitle()+" ("+String.valueOf(currentIndex)+")");
replaceNews.setImageNews(Helpers.GetImageFromUrl(news.getImageNewsAddress()));
SharedVar.getCurrentNews().set(currentIndex, replaceNews);
}
_adapter.notifyDataSetChanged();
}
});
업데이트 2 :
public static Bitmap GetImageFromUrl(String url) {
URL urlForImage;
Bitmap imageNews=null;
try {
urlForImage = new URL(url);
URLConnection conn = urlForImage.openConnection();
imageNews= BitmapFactory.decodeStream(conn.getInputStream());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return imageNews;
}
업데이트 3 :
다시 : 다음 코드처럼 내 코드를 변경했습니다. 홍 모드는 여전히 해결되지 않습니다.
public class AsyncTaskReadImageNews extends AsyncTask<Void, Void, Void>{
@Override
protected Void doInBackground(Void... arg0) {
(MainActivity.this).runOnUiThread(new Runnable() {
@Override
public void run() {
for(News news : SharedVar.getCurrentNews()){
int currentIndex=news.getIndex();
Log.d("INDEX_ITEM", String.valueOf(currentIndex));
News replaceNews=new News();
News oldNews =_adapter.getItem(currentIndex);
replaceNews.setTitle(oldNews.getTitle()+" ("+String.valueOf(currentIndex)+" )");
replaceNews.setImageNews(Helpers.GetImageFromUrl(news.getImageNewsAddress()));
SharedVar.getCurrentNews().set(currentIndex, replaceNews);
}
}
});
return null;

@Override
