高德地圖精確查詢與定位RegeocodeQuery與GeocodeQuery
阿新 • • 發佈：2019-01-24
根據輸入的字串精確查詢位置，用GeocodeQuery查詢座標，然後根據獲取到的座標，用RegeocodeQuery查詢地址。例子中用了兩個頁面，一個是顯示地址資訊及定位的頁面，另一個是搜尋頁面，點選搜尋結果返回顯示頁面，顯示資訊並定位：
顯示並定位的頁面：
public class SaleMapActivity extends AppCompatActivity implements GeocodeSearch.OnGeocodeSearchListener { private static final String TAG = "SaleMapActivity"; @BindView2. 搜尋頁面：(R.id.iv_mapBack) ImageView ivMapBack;
