I'm using AsyncHttpClient of loopj to get image file from the internet and display it on typical image view.
I found the convenient handler named FileAsyncHttpClient and I've checked following simple code works as well as I expected.
public class MainActivity extends ActionBarActivity {
ImageView imgView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgView = (ImageView) findViewById(R.id.imgView);
AsyncHttpClient client = new AsyncHttpClient();
client.get("http://www.some_image_url.png",
new FileAsyncHttpResponseHandler(this){
@Override
public void onFailure(int statusCode, Header[] headers, Throwable throwable, File response) {}
@Override
public void onSuccess(int statusCode, Header[] headers, File response) {
imgView.setImageBitmap(BitmapFactory.decodeFile(response.getPath()));
}
});
}
}
But when I use this code in ArrayAdpater class, not in Activity class, setImageBitmap(...) does not work. Moreover, any view controlling seems to be not allowed such as setVisibility(...).
Following code is the one in question.
public class MainActivity extends Activity {
private List<CustomClass> objectList = new ArrayList<CustomClass>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// ... make objectList from given data ... (omitted)
ArrayAdapter<CustomClass> adapter = new CustomListAdapter();
ListView list = (ListView) findViewById(R.id.customListView);
list.setAdapter(adapter);
}
private class CustomListAdapter extends ArrayAdapter<CustomClass> {
private View itemView;
ImageView imgView;
public MemberListAdapter() {
super(MainActivity.this, R.layout.custom_list, objectList);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
itemView = convertView;
if(itemView == null){
itemView = getLayoutInflater().inflate(R.layout.custom_list, parent, false);
}
CustomClass currentObj = objectList.get(position);
imgView = (ImageView) itemView.findViewById(R.id.imgView);
AsyncHttpClient client = new AsyncHttpClient();
client.get("http://www.some_image_url.png",
new FileAsyncHttpResponseHandler(this){
@Override
public void onFailure(int statusCode, Header[] headers, Throwable throwable, File response) {}
@Override
public void onSuccess(int statusCode, Header[] headers, File response) {
imgView.setImageBitmap(BitmapFactory.decodeFile(response.getPath()));
}
});
return itemView;
}
}
}
I don't know why this is not working. Please let me get an advice. Thanks.
p.s. I've checked controlling view inside the adapter but outside the handler is possible.
