Android Custom Adapter with Bar Progress
- by xger86x
Hi,
i have a custom adapter for an arraylist.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ProgressBar android:id="@+id/downloadprogress"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="200dip"
android:layout_height="wrap_content"
android:max="100"
android:progress="50"
android:secondaryProgress="75" />
<TextView android:id="@+id/tripsname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
but when i try to access to the progress bar in the adapter
private class MyAdapter extends ArrayAdapter<Trip> {
int resource;
public MyAdapter(Context context, int resource, ArrayList<Trip> items) {
super(context, resource,items);
this.resource=resource;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LinearLayout tripListItemView;
final Trip t = getItem(position);
String name = t.getName();
boolean offline = t.isOffline() ;
if(convertView==null) {
tripListItemView = new LinearLayout(getContext());
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater vi;
vi = (LayoutInflater)getContext().getSystemService(inflater);
vi.inflate(resource, tripListItemView, true);
}
else {
tripListItemView = (LinearLayout) convertView;
}
setProgressBarVisibility(true);
View v = findViewById(R.id.downloadprogress);
ProgressBar progressHorizontal = (ProgressBar) findViewById(R.id.downloadprogress);
it always return null, like it doesn't find the progress bar. However, the progress bar is shown in the list, but i need to access to it inside the adapter.
Anybody knows the solution?
Thanks
