처음으로 본 에러라 어떻게 해야 할지 모르겠네요.

custom_list.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> arg0, View arg1, final int arg2, long arg3) {
// TODO Auto-generated method stub
//arg2는 position;
final Cursor c = (Cursor)adapter.getItem(arg2);
//삭제 AlertDialog 생성
new AlertDialog.Builder(Measure.this)
.setTitle(R.string.app_notification)
//StripInfo(Integer.parseInt(c.getString(5))) + " " +
.setMessage(c.getString(1).substring(0,4)+"-"+c.getString(1).substring(4, 6)+"-"+c.getString(1).substring(6, 8) + " " + c.getString(2) + " " + c.getString(3).replace("$", "/") +"ppm"+ " " + getString(R.string.measure_message_delete))
.setPositiveButton(R.string.app_yes,new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Global.DBadapter.DeleteData(Hardness_M.USER_NAME, Integer.parseInt(c.getString(0)));
UpdateList();
series.getPoints().clear();
chart_handler.obtainMessage(graph_flag).sendToTarget();
}
})
.setNegativeButton(R.string.app_no,null)
.show();
return false;
}
});
