I am use data from web using XML parser and setting data using custom adapter for this use asyncTask . My problem is that some devices like Samsang duos,gallaxy work perfectly but on micromax devices it will not work properly.
My adapter is
public class HallBookingAdapter extends ArrayAdapter<MyHall> {
private Context context;
private ArrayList<MCCIAHall> halls;
private int resource;
MyHall objHall;
public int count;
View view;
public static Boolean isScrollingHalls=true;
LayoutInflater inflater;
static class HallBookingHolder
{
public TextView txtTitle,txtLocation,txtCapacity,txtCapacityTitle;
public ImageView imgHall;
public LinearLayout hallBookingLayout;
}
public HallBookingAdapter(Context context, int resource, ArrayList<MyHall> halls) {
super(context, resource, halls);
this.context=context;
this.halls=halls;
this.resource=resource;
inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
count=halls.size();
return halls.size();
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
view=convertView;
objHall=halls.get(position);
HallBookingHolder holder=new HallBookingHolder();
if (convertView==null) {
view = inflater.inflate(resource, null);
holder.txtTitle=(TextView)view.findViewById(R.id.txtListHallTitle);
holder.txtLocation=(TextView)view.findViewById(R.id.txtListHallLocation);
holder.txtCapacity=(TextView)view.findViewById(R.id.txtListHallCapacity);
holder.txtCapacityTitle=(TextView)view.findViewById(R.id.txtListHallCapacityHeadding);
holder.imgHall=(ImageView)view.findViewById(R.id.imgListHall);
view.setTag(holder);
}
else
{
holder = (HallBookingHolder)convertView.getTag();
}
//Creating the Font to the text
Typeface tfLight = Typeface.createFromAsset(context.getAssets(),"OpenSans-Light.ttf");
Typeface tfRegular = Typeface.createFromAsset(context.getAssets(),"OpenSans-Regular.ttf");
Typeface tfsemiBold = Typeface.createFromAsset(context.getAssets(),"OpenSans-Semibold.ttf");
//Setting the font
holder.txtTitle.setTypeface(tfRegular);
holder.txtLocation.setTypeface(tfLight);
holder.txtCapacity.setTypeface(tfsemiBold);
holder.txtCapacityTitle.setTypeface(tfLight);
//Setting data to textview and image
holder.txtTitle.setText(objHall.hallName);
holder.txtLocation.setText(objHall.location);
holder.txtCapacity.setText(objHall.capacity);
//Using Guild Library Image Load using image web url
String imgurl=objHall.getImageUrl();
Glide.load(imgurl).centerCrop().into(holder.imgHall);
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent=new Intent(context, HallDetailsActivity.class);
intent.putExtra("position", position);
context.startActivity(intent);
}
});
return view;
}
}
read it listview smooth-scrolling
Using a background thread ("worker thread") removes strain from the main thread so it can focus on drawing the UI. In many cases, using AsyncTask provides a simple way to perform your work outside the main thread. AsyncTask automatically queues up all the execute() requests and performs them serially. This behavior is global to a particular process and means you don’t need to worry about creating your own thread pool.
