Php SearchView总是给出前几个json值的值

当我将内容写入搜索框时，它会正确过滤，但过滤后，如果我单击任何项目，它总是在同一位置打开上一个项目的值。这些值始终是json值的前几个值。我应该如何解决此问题？

给你

您在建议侦听器中获得的位置与相应的搜索查询结果集相对应。您不能使用相同的位置

CursorAdapter ca = searchView.getSuggestionsAdapter(); 
Cursor cursor = ca.getCursor();
If (cursor.moveToPosition(position)) {
 String selectedID = cursor.getString(cursor.getColumnIndex("id");
 searchView.setQuery(cursor.getString(cursor.getColumnIndex("title")),false); 
 Log.d("strArr id",strArrData[position].id); 
 Intent intent = new Intent(SearchActivity.this,RetrieveIndividualWarehouseSales.class);
 intent.putExtra("pid",selectedID); 
 startActivity(intent);
 }

---

出现此错误android.database.CursorIndexOutOfBoundsException:请求的列：-1，#个列：2My bad。这应该是标题而不是id。String selectedID=cursor.getString（cursor.getColumnIndex（“标题”）；selectedID是标题的值而不是id
