這是我的代碼。我試過這段代碼，但是在MapActivity，MapView和其他位置有錯誤。而當我把光標放在那裏時，我寫這段代碼，它不顯示導入選項......我不知道爲什麼。與此代碼的方法並不here..check導入它PLZ任何一個嘗試我沒有得到MapView和任何一個確切的位置幫助我嗎？
package com.bened;
import android.os.Bundle;
public class mapExactDemoActivity extends MapActivity {
/** Called when the activity is first created. */
MapView mv;
double lat=17.441966,lon=78.445127;
GeoPoint gp;
MapController mc;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mv=(MapView)findViewById(R.id.map);
gp=new GeoPoint((int)(lat*1000000),(int)(lon*1000000));
mc=mv.getController();
mc.setCenter(gp);
mc.setZoom(20);
mv.setBuiltInZoomControls(true);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}

您可以添加logcat嗎？ – aNi
請編輯您的問題並插入您收到的錯誤（例外？）。這將幫助其他用戶瞭解您的問題。 – oers
我試圖通過修正語法來解決你的問題，但我無法弄清楚你的意思是「如果我把光標放在那裏，它不會導入選項」。你能改述一下嗎？ –
