在nutiteq上繪製標記時位圖大小超過32位

Question

我在我的android應用程序中創建動態地圖標記，但有時我得到了OutOfMemoryError和IllegalArgumentException，它們具有相同的logcat錯誤。這裏是我的代碼來繪製多個標記

for (int i = 0; i < lats.size(); i++) { 
     // draw marker 
     Bitmap markerBitmap = UnscaledBitmapLoader.decodeResource(getResources(), R.drawable.ic_place); 
     MarkerStyle markerStyle = MarkerStyle.builder().setBitmap(markerBitmap).setSize(0.5f).setColor(Color.RED).build(); 

     // define custom label 
     try { 
      Label markerLabel = new DefaultLabel("", data.get(i)); 
      // define map location marker, convert to base map coordinate 
      MapPos position = maplayer.getProjection().fromWgs84(Double.parseDouble(lngs.get(i)), Double.parseDouble(lats.get(i))); 

      // add marker to the current map layer 
      markerLayer = new MarkerLayer(maplayer.getProjection()); 
      marker = new Marker(position, markerLabel, markerStyle, markerLayer); 
      markerLayer.add(marker); 
      mapView.getLayers().addLayer(markerLayer); 
     } catch (Exception e) { 
      Log.d("Error Marker", e.getMessage() + " " + e.getCause()); 
     } catch (OutOfMemoryError e){ 
      Toast.makeText(getApplicationContext(), "OutOfMemory " + e.getMessage() + " " + e.getCause(), Toast.LENGTH_LONG).show(); 
      Log.d("OutOfMemory", e.getMessage() + " " + e.getCause()); 
     } 
    } 

，這是logcat的錯誤

是否有人遇到這個？我會感謝任何幫助。謝謝。

你爲每個標記做了很多位圖副本，爲什麼不把這些行放在for（）之前，並且爲標記使用相同的位圖和樣式？

 Bitmap markerBitmap = UnscaledBitmapLoader.decodeResource(getResources(), R.drawable.ic_place); 
     MarkerStyle markerStyle = MarkerStyle.builder().setBitmap(markerBitmap).setSize(0.5f).setColor(Color.RED).build(); 

你甚至每個標記創建新的圖層，所以請之前也把這些線（）：

 markerLayer = new MarkerLayer(maplayer.getProjection()); 
    mapView.getLayers().addLayer(markerLayer); 

因此，代碼是：

Bitmap markerBitmap = UnscaledBitmapLoader.decodeResource(getResources(), R.drawable.ic_place); 
    MarkerStyle markerStyle = MarkerStyle.builder().setBitmap(markerBitmap).setSize(0.5f).setColor(Color.RED).build(); 

    markerLayer = new MarkerLayer(maplayer.getProjection()); 
    mapView.getLayers().addLayer(markerLayer); 

    for (int i = 0; i < lats.size(); i++) { 
     // draw marker 
     // define custom label 
     try { 
      Label markerLabel = new DefaultLabel("", data.get(i)); 
      // define map location marker, convert to base map coordinate 
      MapPos position = maplayer.getProjection().fromWgs84(Double.parseDouble(lngs.get(i)), Double.parseDouble(lats.get(i))); 

      // add marker to the current map layer 
      marker = new Marker(position, markerLabel, markerStyle, markerLayer); 
      markerLayer.add(marker); 
     } catch (Exception e) { 
      Log.d("Error Marker", e.getMessage() + " " + e.getCause()); 
     } catch (OutOfMemoryError e){ 
      Toast.makeText(getApplicationContext(), "OutOfMemory " + e.getMessage() + " " + e.getCause(), Toast.LENGTH_LONG).show(); 
      Log.d("OutOfMemory", e.getMessage() + " " + e.getCause()); 
     } 
    }
