（4.3.1.15.1）抽屉控件+NavigationLeftFragment的方案修改

原来为：

<fragment
                android:id="@+id/navigation_drawer_old"
                android:name="com.android.yunshi.fragment.NavigationLeftFragment"
                android:layout_width="@dimen/navigation_drawer_width"
                android:layout_height="match_parent"
                android:layout_gravity="start"
                android:visibility="gone"
                tools:layout="@layout/fragment_navigation_drawer" />

mNavigationDrawerFragment = (NavigationLeftFragment) getSupportFragmentManager()
		//		.findFragmentById(R.id.navigation_drawer);
mNavigationDrawerFragment.setUp(R.id.navigation_drawer,
				(DrawerLayout) findViewById(R.id.yunshi_root));

这几天，收集到的回馈中，有大量错误这样就会出现错误： 

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.android.yunshi/com.android.yunshi.MainActivity}: android.view.InflateException: Binary XML file line #25: Error inflating class fragment

	at dalvik.system.NativeStart.main(Native Method)

     原因就是，v4.fragment不支持<fragment>静态标签，部分型号的手机，会导致程序崩溃

解决方案：

mNavigationDrawerFragment=new NavigationLeftFragment();
		FragmentManager fragmentManager = getSupportFragmentManager();  
		FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();  
		fragmentTransaction.replace(R.id.navigation_drawer, mNavigationDrawerFragment);
		fragmentTransaction.commit();
		fragmentManager.executePendingTransactions();
		// Set up the drawer.  找到抽屉控件
		mNavigationDrawerFragment.setUp(R.id.navigation_drawer,
				(DrawerLayout) findViewById(R.id.yunshi_root));

注意，一定要fragmentManager.executePendingTransactions();  立即提交事务

不然commit()总是在activity的UI完成后，才提交，这样你在Fragment中的getActivity（）就会报错，因为是空
