Почему мой списокView не будет очищен?

Question

У меня проблема с моим списком, когда я нажимаю кнопку очистки, я ожидаю, что мой список будет очищен (очевидно), но по какой-то причине мой список не очищает здесь код ниже, любая помощь будет оценена. Спасибо

MainClass

public class MainActivity extends AppCompatActivity { 
ArrayList<SearchResults> searchResults; 
private FloatingActionButton add; 
private FloatingActionButton clear; 
ArrayList<SearchResults> results = new ArrayList<SearchResults>(); 
final Context context = this; 
String time1, people1, description1, mDate, hour, minute, MeridiemIndicator, dateNumber; 
int Year, Month, Day, Hour, Minute; 


@Override 
public void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 
    searchResults = new ArrayList<SearchResults>(); 
    setContentView(R.layout.activity_main); 
    final ListView lv1 = (ListView) findViewById(R.id.ListView); 
    final CustomAdapter myAdapter = new CustomAdapter(context, R.layout.custom_row_view, results); 
    lv1.setAdapter(myAdapter); 


    add = (FloatingActionButton) findViewById(R.id.add); 
    add.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(final View view) { 

      dialogMethod(lv1); 
     } 


    }); 

    lv1.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
      CustomAdapter adapter = (CustomAdapter) parent.getAdapter(); 
      adapter.remove(results.get(position)); 
      adapter.notifyDataSetChanged(); 


     } 
    }); 
    lv1.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { 
     @Override 
     public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long l) { 
      CustomAdapter adapter = (CustomAdapter) parent.getAdapter(); 
      adapter.remove(results.get(position)); 
      adapter.notifyDataSetChanged(); 
      dialogMethod(lv1); 

      return false; 
     } 


    }); 
    clear = (FloatingActionButton) findViewById(R.id.clear); 
    clear.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(final View view) { 
      results.clear(); 
      myAdapter.notifyDataSetChanged(); 
     } 


    }); 
} 

private ArrayList<SearchResults> GetSearchResults() { 


    SearchResults sr1 = new SearchResults(); 
    sr1.setName(" Meeting With: " + people1); 
    sr1.setTimeOfMeeting(" Starts At: " + time1); 
    sr1.setDescription(" Details: " + description1); 
    sr1.setDate(" Date: " + mDate); 
    sr1.setDateNumber(dateNumber); 
    results.add(sr1); 
    Collections.sort(results, new Comparator<SearchResults>() { 
     public int compare(SearchResults x, SearchResults y) { 
      return Integer.parseInt(x.getDateNumber()) - Integer.parseInt(y.getDateNumber()); 
     } 
    }); 


    return results; 
} 

Вот мой заказ адаптер

public class CustomAdapter extends ArrayAdapter { 
private static ArrayList<SearchResults> searchArrayList; 
private LayoutInflater mInflater; 


public CustomAdapter(Context context, int custom_row_view, ArrayList<SearchResults> results) { 
    super(context,custom_row_view,results); 

    searchArrayList = results; 
    mInflater = LayoutInflater.from(context); 

} 

public int getCount() { 
    return searchArrayList.size(); 
} 

public Object getItem(int position) { 
    return searchArrayList.get(position); 
} 

public long getItemId(int position) { 
    return position; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 
    ViewHolder holder; 
    if (convertView == null) { 
     convertView = mInflater.inflate(R.layout.custom_row_view, null); 
     holder = new ViewHolder(); 
     holder.txtName = (TextView) convertView.findViewById(R.id.name); 
     holder.txtTimeOfMeeting = (TextView) convertView.findViewById(R.id.timeOfMeeting); 
     holder.txtDescription = (TextView) convertView.findViewById(R.id.description); 
     holder.txtDate = (TextView) convertView.findViewById(R.id.date); 

     convertView.setTag(holder); 
    } else { 
     holder = (ViewHolder) convertView.getTag(); 
    } 

    holder.txtName.setText(searchArrayList.get(position).getName()); 
    holder.txtTimeOfMeeting.setText(searchArrayList.get(position).getTimeOfMeeting()); 
    holder.txtDescription.setText(searchArrayList.get(position).getDescription()); 
    holder.txtDate.setText(searchArrayList.get(position).getDate()); 

    return convertView; 
} 

static class ViewHolder { 
    TextView txtName; 
    TextView txtTimeOfMeeting; 
    TextView txtDescription; 
    TextView txtDate; 
    } 
} 

Проблема более конкретно находится в главном методе чуть ниже кнопки плавающих действий «ясно». Еще раз спасибо

Answer 1

После того,

clear.setOnClickListener(new View.OnClickListener() { 

    @Override 
    public void onClick(final View view) { 
     results.clear(); 
     CustomAdapter myAdapter = new CustomAdapter(context, R.layout.custom_row_view, results); 
lv1.setAdapter(myAdapter); 
     myAdapter.notifyDataSetChanged(); 
    } 


}); 

ИЛИ

Clear адаптер

myAdapter.clear(); 
myAdapter.notifyDataSetChanged();
