I wrote a code to download an image from internet. And i have to show it in a ImageView
which is dynamically created.
And i am getting an error that Only the original thread that created a view hierarchy can touch its views. I know i have to write a handle but how can i do that?
Here is my code:
public class ResimCek implements Runnable {
int resimID = 0;
public ResimCek(int parcaID) {
// store parameter for later user
resimID = parcaID;
}
public void run() {
int resID = getResources().getIdentifier(Integer.toString(resimID) , "tag", getPackageName());
ImageView resim = (ImageView) findViewById(resID);
Drawable image = ImageOperations(getBaseContext(),"http://141.11.11.206/parca/" + Integer.toString(resimID) + ".jpg" ,"I" + Integer.toString(resimID) + ".jpg");
// I AM GETTING ERROR HERE ******************
resim.setImageDrawable(image); // *************************
}
}
private Drawable ImageOperations(Context ctx, String url, String saveFilename) {
try {
InputStream is = (InputStream) this.fetch(url);
Drawable d = Drawable.createFromStream(new URL(url).openConnection().getInputStream(),saveFilename);
return d;
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
public Object fetch(String address) throws MalformedURLException,IOException {
URL url = new URL(address);
Object content = url.getContent();
return content;
}
private void MalzemeEkle(String malzemeKodu, String malzemeTanimi) {
ImageView parcaresmi = new ImageView(this);
parcaresmi.setId(Integer.parseInt(malzemeKodu));
Runnable r = new ResimCek(Integer.parseInt(malzemeKodu));
new Thread(r).start();
}
public class ResimCek implements Runnable {
int resimID = 0;
public ResimCek(int parcaID) {
// store parameter for later user
resimID = parcaID;
}
public void run() {
int resID = getResources().getIdentifier(Integer.toString(resimID) , "tag", getPackageName());
ImageView resim = (ImageView) findViewById(resID);
Drawable image = ImageOperations(getBaseContext(),"http://141.11.11.206/parca/" + Integer.toString(resimID) + ".jpg" ,"I" + Integer.toString(resimID) + ".jpg");
// I AM GETTING ERROR HERE ******************
resim.setImageDrawable(image); // *************************
}
}
new Handler().post(new ResimCek(Integer.parseInt(malzemeKodu))); instead of new Thread(r).start();
by any case if this is an Activity.. then
runOnUIThread(new ResimCek(Integer.parseInt(malzemeKodu))); `instead of new Thread(r).start();`
will also work..
