好的，所以我剛開始使用Android開發，基本上我的問題是標題描述。我到現在爲止所嘗試的是創建一個默認的Drawer Navigation Activity項目並編寫一個Google Maps Fragment類，最後將其膨脹爲主要內容。無法使用導航抽屜繪製Google Maps v2
我希望這項工作的原因是因爲Drawer Nav Activity看起來很不錯，並且在它的主屏幕中顯示Google地圖會很好。
通過閱讀Docs：http://developer.android.com/guide/components/fragments.html我知道，爲了在另一個活動中成功顯示片段，您需要首先創建一個Google Maps類，它擴展MapFragment或Fragment，然後在活動的佈局文件中聲明該片段。
無論我嘗試過什麼，它都無法工作。我設法成功繪製Google地圖，但其類別代碼未被調用，因此地圖操作不存在。
谷歌地圖負責GMapsFragment類（我認爲標記線以下（35）與所述地圖xml文件造成一起選擇的錯誤）：
package com.example.s0me0n3.ytgooglemapstut;
import android.app.Fragment;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;

import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class GMapsFragment extends Fragment {
public MapView mapView;
private static GoogleMap googleMap;
public GMapsFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
Log.w("GMAPS", "Map place 1");
// **********************************************************************************
// The line below throws an inflation error when trying to parse the fragment_map xml
// **********************************************************************************
View rootView = inflater.inflate(R.layout.fragment_map, container, false);
// Log.w("GMAPS", "Map place 1");
if (googleMap != null)
setUpMap();
if (googleMap == null) {
googleMap = ((MapFragment) MyActivity.fragmentManager.findFragmentById(R.id.ContactMapView)).getMap();
if (googleMap != null) {
setUpMap();
}
}
return rootView;
}
private static void setUpMap() {
googleMap.setMyLocationEnabled(true);
googleMap.addMarker(new MarkerOptions().position(new LatLng(41.009471, 28.916134)).title("baslik"));
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(41.009471, 28.916134), 12.0f));
}
@Override
public void onDestroyView() {
super.onDestroyView();
if (googleMap != null) {
MyActivity.fragmentManager.beginTransaction()
.remove(MyActivity.fragmentManager.findFragmentById(R.id.ContactMapView))
.commit();
googleMap = null;
}
}
}
和主活動類MyActivity：
package com.example.s0me0n3.ytgooglemapstut;
import android.app.Activity;
import android.app.ActionBar;
import android.app.Fragment;
import android.app.FragmentManager;

private NavigationDrawerFragment mNavigationDrawerFragment;
/**

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
mNavigationDrawerFragment = (NavigationDrawerFragment)
getFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// _gmaps = (GMapsFragment)
// getFragmentManager().findFragmentById(R.id.ContactMapView);
// FragmentTransaction fragmentTransaction = _gmaps.beginTransaction();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
// *** The Note below is pointing here! ***
GMapsFragment fragment = new GMapsFragment();
fragmentTransaction.add(R.id.container, fragment);
fragmentTransaction.commit();
}
@Override
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
.commit();
}
public void onSectionAttached(int number) {

actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setTitle(mTitle);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
if (!mNavigationDrawerFragment.isDrawerOpen()) {
// Only show items in the action bar relevant to this screen
// if the drawer is not showing. Otherwise, let the drawer
// decide what to show in the action bar.
getMenuInflater().inflate(R.menu.my, menu);
restoreActionBar();
return true;
}
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {

// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
// showMsg("Settings reeee");
// Log.w("MyActivity", "Will now log u out...");
Intent intent = new Intent();

// return true;

return super.onOptionsItemSelected(item);
}
private void showMsg(String msg) {
Toast toast = Toast.makeText(this, msg, Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, toast.getXOffset()/2, toast.getYOffset()/2);

}
@Override

return rootView;
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
((MyActivity) activity).onSectionAttached(
getArguments().getInt(ARG_SECTION_NUMBER));
}
}
}
注意：如果我改變第73行「GMapsFragment fragment = new GMapsFragment（）;」在類似這樣的MyActivity類「片段片段=新的MapFragment（）;」那麼它工作正常，但GMapsFragment當然沒有運行。相反，默認的gmaps根本沒有功能。但是，我不明白爲什麼我自己的gmaps片段的通脹不起作用。
在那之後，我明白我必須包括對主XML裏面的谷歌地圖片段..所以這裏是activity_my.xml：
<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MyActivity">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.

android:layout_gravity="left" instead. -->
<!-- The drawer is given a fixed width in dp and extends the full height of
the container. -->
<fragment android:id="@+id/navigation_drawer"
android:layout_width="@dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
android:name="com.example.s0me0n3.ytgooglemapstut.NavigationDrawerFragment"
tools:layout="@layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
和fragment_map.xml：
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/ContactMapView"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
這裏是我的AndroidManifest.xml：

的logcat的錯誤，我る後我收到nning應用程序是：

最後的話。我試圖運行從其他XML文件中的GMapsFragment類或my_activity.xml但我總是最後得到錯誤。
所以，之後牆上的垃圾郵件，讓我向你解釋我的目標。我想使用Android Studio中默認生成的Drawer Nav代碼，並結合主內容上顯示的Google地圖。
任何啓蒙會很棒。我一直在尋找最後6天的解決方案，但沒有運氣。它必須是一個非常愚蠢的錯誤，我知道但我被卡住了。
P.S：我已經看過使用SupportMapFragment的例子，但是我想讓我的上面的代碼工作，或者理解爲什麼這是不可能的，如果是這樣的話。
