Hi i'm trying to add an image to an ImageView from a URL i have tried loading it as a bitmap but nothing is showing. so does anyone know what the best method to do this is or what i'm doing wrong?
heres my code
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
//Check Preferences which sets UI
setContentView(R.layout.singlenews);
TextView headerText = (TextView) findViewById(R.id.header_text);
headerText.setText("Latest News");
PostTask posttask;
posttask = new PostTask();
posttask.execute();
}
public void loadNews(){
newsStr = getIntent().getStringExtra("singleNews");
try {
JSONObject obj = new JSONObject(newsStr);
content = obj.getString("content");
title = obj.getString("title");
fullName = obj.getString("fullname");
created = obj.getString("created");
NewsImageURL = obj.getString("image_primary");
tagline = obj.getString("tagline");
meta = "posted by: " + fullName + " " + created;
URL aURL = new URL("NewsImageURL");
URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
/* Buffered is always good for a performance plus. */
BufferedInputStream bis = new BufferedInputStream(is);
/* Decode url-data to a bitmap. */
bm = BitmapFactory.decodeStream(bis);
bis.close();
is.close();
/* Apply the Bitmap to the ImageView that will be returned. */
Log.v("lc", "content=" + content);
Log.v("lc", "title=" + title);
Log.v("lc", "fullname=" + fullName);
Log.v("lc", "created=" + created);
Log.v("lc", "NewsImage=" + NewsImageURL);
Log.v("lc", "Meta=" + meta);
Log.v("lc", "tagline=" + tagline);
} catch
(JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public class PostTask extends AsyncTask<Void, String, Boolean> {
@Override
protected Boolean doInBackground(Void... params) {
boolean result = false;
loadNews();
publishProgress("progress");
return result;
}
protected void onProgressUpdate(String... progress) {
StringBuilder str = new StringBuilder();
for (int i = 1; i < progress.length; i++) {
str.append(progress[i] + " ");
}
}
@Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
Log.v("BGThread", "begin fillin data");

}
}
public void fillData(){

Log.v("BGThread", "Filled results");
adapter = new MergeAdapter();
adapter.addView(NewsView);
setListAdapter(adapter);
