これは、actiobBarSherlock を使用してカスタム アクション バーを作成する方法のコードです。
private void createCustomActionBar() {
List<SiteLink> links = new ArrayList<SiteLink>();
links.add(...)
LinksAdapter linkAdapter = new LinksAdapter(this, R.layout.external_link, links);
View customNav = LayoutInflater.from(this).inflate(R.layout.custom_show_action_bar, null);
IcsSpinner spinner = (IcsSpinner)customNav.findViewById(R.id.spinner);
spinner.setAdapter(linkAdapter);
ImageView refresh = (ImageView) customNav.findViewById(R.id.refresh);
refresh.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
...
}
});
ImageView settings = (ImageView) customNav.findViewById(R.id.settings);
settings.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
...
}
});
getSupportActionBar().setCustomView(customNav, new ActionBar.LayoutParams(Gravity.RIGHT));
getSupportActionBar().setDisplayShowCustomEnabled(true);
}
アダプタ
private static class LinksAdapter extends ArrayAdapter<SiteLink> {
private List<SiteLink> strings;
private Context context;
private LinksAdapter(Context context, int textViewResourceId, List<SiteLink> objects) {
super(context, textViewResourceId, objects);
this.strings = objects;
this.context = context;
}
@Override
public int getCount() {
if (strings == null) return 0;
return strings.size();
}
@Override
public SiteLink getItem(int position) {
return super.getItem(position);
}
// return views of drop down items
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
final SiteLink siteLink = strings.get(position);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// at 0 position show only icon
TextView site = (TextView) inflater.inflate(R.layout.external_link, null);
site.setText(siteLink.getName());
site.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(siteLink.getUrl()));
context.startActivity(i);
}
});
return site;
}
// return header view of drop down
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
return inflater.inflate(R.layout.icon, null);
}
}
