У меня есть Button
в моем ListView
Adapter
.Я хотел бы показать Custom Dialog
после того, как пользователь нажмет на этот Button
.
Как я могу это сделать?
Код Adapter
:
package ...
import ...
public class UserBooksListAdapter extends BaseAdapter {
private List<UserBook> items;
private LayoutInflater inflater;
public UserBooksListAdapter(Activity context, List<UserBook> items) {
super();
this.inflater = LayoutInflater.from(context);
this.items = items;
}
@Override
public int getCount() {
return this.items.size();
}
@Override
public UserBook getItem(int position) {
return this.items.get(position);
}
@Override
public long getItemId(int position) {
return this.items.get(position).hashCode();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
final UserBook item = items.get(position);
if(convertView==null){
vi=inflater.inflate(R.layout.userbook_info, null);
}
//set the elements in the UI for this book
TextView bookName = (TextView) vi.findViewById(R.id.bookName);
TextView booksDates = (TextView) vi.findViewById(R.id.bookDates);
Button LibrariesButton = (Button) vi.findViewById(R.id.LibrariesButton);
final Switch isActive = (Switch) vi.findViewById(R.id.isActive);
//check if the user still get notification for this book (= the book is active).
if (item.getACTIVE().equals("1")){
//the book is active
isActive.setChecked(true);
//coloring the the to white
bookName.setTextColor(0xffffffff);
booksDates.setTextColor(0xffffffff);
} else {
//the book is not active
isActive.setChecked(false);
//coloring the text to gray
bookName.setTextColor(0Xff838383);
booksDates.setTextColor(0Xff838383);
}
//put the values to the TextViews
bookName.setText(item.getBook().getName());
booksDates.setText(item.getSTART_DATE() + " - " + item.getEND_DATE());
//if the user click on Library Button:
LibrariesButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
AlertDialog.Builder mBuilder = new AlertDialog.Builder(UserBooksListAdapter.this);
}
});
return vi;
}
}
