當標記點擊Google地圖時，如何從標記獲取數據到BottomSheet

Question

我正面臨着從標記到BottomSheet的NestedScrollView獲取詳細信息（數據）的問題。 當我點擊標記時，NestedScrollView將從底部向上滾動並顯示相應的數據。我使用JSON來獲取數據。

我的源代碼：

public class SeekingMapActivity extends AppCompatActivity implements 
    GoogleApiClient.OnConnectionFailedListener, 
    GoogleApiClient.ConnectionCallbacks, 
    View.OnClickListener { 

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_seeking_main); 

    ... 

    ArrayList<HashMap<String, String>> location = null; 
    String url = "myURL"; 
    try { 
     JSONArray data = new JSONArray(getHttpGet(url)); 
     location = new ArrayList<HashMap<String, String>>(); 
     HashMap<String, String> map; 

     for (int i = 0; i < data.length(); i++) { 
      JSONObject c = data.getJSONObject(i); 

      map = new HashMap<String, String>(); 
      map.put("title", c.getString("title")); 
      map.put("avatar", c.getString("avatar")); 
      map.put("lat", c.getString("lat")); 
      map.put("mapLong", c.getString("mapLong")); 
      map.put("address", c.getString("address")); 
      location.add(map); 
     } 

    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 

    // googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); 

    IconGenerator tc = new IconGenerator(this); 
    String price = "1200K"; 
    Bitmap bmp = tc.makeIcon(price); // pass the text you want. 

    lat = Double.parseDouble(location.get(0).get("lat").toString()); 
    mapLong = Double.parseDouble(location.get(0).get("mapLong").toString()); 

    LatLng coordinate = new LatLng(lat, mapLong); 
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
    googleMap.getUiSettings().setMapToolbarEnabled(false); 
    googleMap.getUiSettings().setRotateGesturesEnabled(true);  // Enable RotateGestures 
    googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(coordinate, 15)); 

    for (int i = 0; i < location.size(); i++) { 

     lat = Double.parseDouble(location.get(i).get("lat").toString()); 
     mapLong = Double.parseDouble(location.get(i).get("mapLong").toString()); 

     String title = location.get(i).get("title").toString(); 
     String avatar = location.get(i).get("avatar".toString()); 
     String address = location.get(i).get("address").toString(); 

     MarkerOptions marker = new MarkerOptions().position(new LatLng(lat, mapLong)) 
       .title(title) 
       .snippet(address) 
       .icon(BitmapDescriptorFactory.fromBitmap(bmp)); // .anchor(0.5f, 0.6f) 
     googleMap.addMarker(marker); 

     googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() 
     { 
      @Override 
      public boolean onMarkerClick(Marker arg0) { 
       if(isClick==false) 
        mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED); 
       else 
        mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED); 

       isClick=!isClick; 
       // Toast.makeText(SeekingMapActivity.this, arg0.getTitle(), Toast.LENGTH_SHORT).show();// display toast 
       return true; 
      } 
     }); 
    } 
} 
... 

} BottomSheet的

佈局：

我不知道如何從製造商的數據NestedScrollView

例子：

When click: Marker A, data of marker A will display on NestedScrollView 
      Marker B, data of marker B will display on NestedScrollView 

如果您需要更多信息，我會發布更多！

Answer 1

1 - 與您的屬性，如標題，頭像，地址等創建模型類...

2 - 創建模型類型的ArrayList

3 - 將所有這些數據在您的ArrayList

4 - 現在您的標記onMarkerClick方法，迭代for循環，並與您的ArrayList標題/唯一ID的位置如下圖所示比較該標記的標題或唯一ID：

googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() { 
      @Override 
      public boolean onMarkerClick(Marker marker) { 
       for (int i = 0; i < arrayList.size(); i++) { 
        if (marker.getTitle().equals(finalMSearchResultModel.getRecords().get(i).getHotelName())) { 
        // YOUR ACTION GOES HERE 
        } 
       } 
       return false; 
      } 
     });
