這裏我想根據其latlong顯示標記到infowindow中的詳細信息，並且想要做新的事件onclick infowindow。在這裏，我做了一個markerlist和LAT1 long1陣列是從網址服用，你可以看到私人無效setUpMapIfNeeded（）這個函數 這裏nameb是含有標記名稱列表如何在infowindow中顯示各個標記的適當的多個數據

你想添加標記在infowindow中，你從一個特定的網址得到的名稱？ –
@swatisrivastav是的，你是正確的，我從URL獲取所有細節，我將所有數據作爲各自的陣列 – Nitin
好吧。做一件事。首先在logcat中打印名稱，以確認你獲得了各自的lat和long的所有名字。打印3件東西 –
