I have a listview
to be populated/fed by a webservice, but only load my images with a handler.
I want to use a Thread, but only run with a Handler
and I don’t understand why...
Can someone help me?
Here is the code (excerpt):
new Thread(new Runnable() {
public void run() {
do{
if(isOnline()){
initializeArrays();
populateList();
populateListView();
}
}while(!isOnline());
progresso.dismiss();
}
})start();
private void populateListView() {
ArrayAdapter<Clube> adapter = new MyArrayAdapter();
list = (ListView) findViewById(R.id.classificacaoGeral);
list.setAdapter(adapter);
list.setOnItemClickListener(this);
}
private class MyArrayAdapter extends ArrayAdapter<Clube> {
public MyArrayAdapter() {
super(Main.this, R.layout.list_item, clubes);
}
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = getLayoutInflater().inflate(R.layout.list_item,
parent, false);
}
// Counter de position no Ranking
if(position == 0){
convertView.setBackgroundColor(Color.rgb(235, 235, 235));
}else if(position == 1){
convertView.setBackgroundColor(Color.rgb(240, 240, 240));
}else if(position == 2){
convertView.setBackgroundColor(Color.rgb(249, 249, 249));
}else{
convertView.setBackgroundColor(Color.rgb(255, 255, 255));
}
Clube actual = clubes.get(position);
TextView tv = (TextView) convertView.findViewById(R.id.item_name);
tv.setText(actual.getName());
// Logo do clube
ImageView imgView = (ImageView) convertView
.findViewById(R.id.item_img);
imgView.setImageBitmap(this.getClubeLogo(actual.getImgURL()));
// ID de Clube de acordo com a BD
TextView pontos = (TextView) convertView
.findViewById(R.id.item_pontos);
pontos.setText(actual.getPontos() +" pontos");
return convertView;
}
/**
* Metodo para fazer o load de uma imagem por um URL
*
* @param src
* String de URL de image
* @return Bitmap
*/
private Bitmap getClubeLogo(String src) {
try {
URL url = new URL(src);
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap logo = BitmapFactory.decodeStream(input);
return logo;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
What exactly is the problem? This code works or presents some error?
