我想在Android中創建應用,並且我想在導航抽屜中添加地圖。抽屜選項打開新的碎片,但無法使Map碎片工作。無法將谷歌地圖添加到導航抽屜片段
的MainActivity.java設置片段方式如下:
/**
* Diplaying fragment view for selected nav drawer list item
* */
private void displayView(int position) {
// update the main content by replacing fragments
Fragment fragment = null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new PoliFragment();
break;
case 2:
fragment = new TilefonaFragment();
break;
case 3:
fragment = new DromologiaFragment();
break;
case 4:
fragment = new XartisFragment();
break;
default:
break;
}
if (fragment != null) {
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
//setTitle(navMenuTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
// error in creating fragment
Log.e("MainActivity", "Error in creating fragment");
}
}
的地圖片段(XartisFragment.java)如下:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
public class XartisFragment extends Fragment {
private GoogleMap map;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.map_layout,container, false);
map = ((SupportMapFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.map)).getMap();//((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map)).getMap();
return rootView;
}
}
的map_layout.xml是以下內容:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="8dp" />
</RelativeLayout>
當我嘗試運行它,我得到:
Error:(178, 15) error: incompatible types: XartisFragment cannot be converted to Fragment
它指向錯誤此行MainActivity.java關於以使其加載哪些改變
fragment = new XartisFragment();
任何想法?
import android.support.v4.app.Fragment;在哪裏displayView()方法類 – 2014-10-28 10:58:45
fragmentManager.beginTransaction() .replace(R.id.frame_container,fragment).commit();錯誤從此處拋出。 – 2014-10-28 10:59:29
