Android谷歌地圖自定義標記

我使用自定義標記爲我的谷歌地圖。所有的標記圖像都從服務器獲得，並藉助延遲加載我可以顯示。問題是，如果在圖像下載完成之前設置製造商，則不會使用新圖像更新地圖。Android谷歌地圖自定義標記

任何幫助，將不勝感激

想要在圖像完成下載時更改標記圖標嗎？ –

也許這有助於：http://stackoverflow.com/questions/13733299/initialize-mapfragment-programmatically-with-maps-api-v2 – runDOSrun

@Rod_Algonquin：是的，但問題是圖像正在第二次渲染更新只:( – Bytecode

發出定額。谷歌地圖標記有setIcon方法，它可以幫助我們更新圖標。所以每當我從圖片下載器得到回調，我都會通過setIcon方法更新它。到目前爲止沒有問題，工作完美。
