(新手求救)关于MapActivity的使用问题，困扰几天了
有三个页面（android 新手，姑且这样称呼吧），A登录页面（普通Activity），B功能页面（普通Activity），C地图页面(MapActivity)，在模拟器中,登录过后，显示功能页面，点击功能页面某按钮显示地图页面，但是当跳转到C页面时，又被自动返回到A页面中了，地图就是不显示，如果直接显示C页面没问题，或者从B页面直接点击到C页面也是没问题，
部分代码：
登录后：
if(responsepost.getStatusLine().getStatusCode()==200){
String result=EntityUtils.toString(responsepost.getEntity());
JSONObject resultobj=new JSONObject(result.toString());
//在这里解析json .......
Intent intent=new Intent();
intent.setClass(Login.this,MapShow.class);
startActivity(intent);
}else{
tvTip.setText("请求失败，请检查网络。");
}
b页面按钮事件：
button1.setOnClickListener(new View.OnClickListener() {
//@Override
public void onClick(View v) {
Intent intent = new Intent(MapShow.this, DisplayMap.class);
Bundle bundle = new Bundle();
double longitude = Double.valueOf(114.567421);
double latitude = Double.valueOf(40.491295);
int lat = (int) (latitude * 1E6);
int lng = (int) (longitude * 1E6);
bundle.putInt(ConstConfiguration.BUDDLE_INT_KEY_LAT, lat);
bundle.putInt(ConstConfiguration.BUDDLE_INT_KEY_LON, lng);
intent.putExtras(bundle);
startActivity(intent);
}
});
地图页部分代码：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mapview);
MapView map = (MapView)findViewById(R.id.map);//获得MapView对象
int longitude = 113085530;
int latitude = 28240846;
mGeoPoint = new GeoPoint(latitude,longitude);
MapController mapControl = map.getController();
//map.getController().setCenter();//设置地图中心
mapControl.animateTo(mGeoPoint);
mapControl.setZoom(15);//设置缩放级别
map.setBuiltInZoomControls(true);
map.setFocusable(true);
MyLocationOverlay myLocationOverlay = new MyLocationOverlay();
List<Overlay> list = map.getOverlays();
list.add(myLocationOverlay);
}

[解决办法]
好想把你的代码直接拿过来改
