在 Android 中搜索取决于微调器的值

Question

我创建了一个显示地点列表的应用程序，并创建了一个搜索对话框，用户可以在其中输入编辑文本，这样 he/she 就会找到所需的地点。首先，搜索在它唯一的地方工作，我尝试添加微调器，其值是地方的区域，我在下面的行上遇到问题 post。

GetSearchPlace = dbhelper.getPlaceSearch(placeLocationEditText.getText().toString(),dbhelper.getPlaceSearch(placeRegion.getSelectedItem().toString()));

它说 DatabaseHelper 中的 getPlaceSearch (String, string) 不能应用于 (String)

这是我的数据库助手

public List<PlaceModel> getPlaceSearch(String location, String region) {
        List<PlaceModel> search = new ArrayList<PlaceModel>();

        String selectQuery = "SELECT * FROM listing_place where province_name like '" + location + "' and region = '"+region+"'";
        SQLiteDatabase db = this.getReadableDatabase();
        Cursor cursor = db.rawQuery(selectQuery, null);

        if (cursor.moveToFirst()) {
            do {
                PlaceModel pm = new PlaceModel();
                pm.setlisting_title(cursor.getString(cursor.getColumnIndex(KEY_PLACE)));
                search.add(pm);
            }
            while (cursor.moveToNext());
        }
        cursor.close();
        return search;
    }

这是我的主要activity

final Spinner placeRegion = (Spinner) dialog.findViewById(R.id.spinnerregion);
                ArrayAdapter<String> RegionAdapter = new ArrayAdapter<String>(MainActivity.this,R.layout.spinner_layout, db.getAllRegion());
                RegionAdapter.setDropDownViewResource(R.layout.spinner_layout);
                placeRegion.setAdapter(RegionAdapter);
    placeLocationEditText = (EditText)dialog.findViewById(R.id.placelocation);

                    Button button = (Button) dialog.findViewById(R.id.btnplacesearch);

                    button.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            dialog.dismiss();

                            PlaceListView = findViewById(R.id.placelayout);
                            ViewGroup parent = (ViewGroup) PlaceListView.getParent();
                            parent.removeView(PlaceListView);
                            PlaceSearchView = getLayoutInflater().inflate(R.layout.searchresult_place, parent, false);
                            parent.addView(PlaceSearchView);

                            GetSearchPlace = dbhelper.getPlaceSearch(placeLocationEditText.getText().toString(),dbhelper.getPlaceSearch(placeRegion.getSelectedItem().toString()));
                            lv2 = (ListView) findViewById(R.id.searchplace_list);
                            lv2.setAdapter(new ViewAdapterSearchPlace());

确定将您的代码替换为下面..

GetSearchPlace = dbhelper.getPlaceSearch(placeLocationEditText.getText().toString(),placeRegion.getSelectedItem().toString());
