小賴的實戰記錄

我使用了ViewPager 跟  MapView的組合，

結果，發生不少錯誤是

MapView.onCreate(Unknow Source)

的問題。

 

找到一個比較能解決問題是下面這個連結

https://code.google.com/p/gmaps-api-issues/issues/detail?id=6237#c9

public void onSaveInstanceState(Bundle outState){
   //This MUST be done before saving any of your own or your base class's variables
   final Bundle mapViewSaveState = new Bundle(outState);
   mapView.onSaveInstanceState(mapViewSaveState);
   outState.putBundle("mapViewSaveState", mapViewSaveState);
   //Add any other variables here.
   super.onSaveInstanceState(outState);
}

public void onCreate(Bundle savedInstanceState){
     super.onCreate(savedInstanceState);
     final Bundle mapViewSavedInstanceState = savedInstanceState != null ? savedInstance.getBundle("mapViewSaveState") : null;
     mapView.onCreate(mapViewSavedInstanceState);
     //....
}

不過滑動時有遲頓遲頓的感覺，

後來覺得，可能MapView 加上 ViewPager，可能不適合，（好像也沒人這樣幹）

不然感覺效能很差，最後覺得該放棄使用。
