无法更改我的导航抽屉中ActionBar中应用程序图标旁边的Up插入符号

我目前正在尝试按照Google IO 2013指南实施新的NavigationDrawer。 我正在使用ActionbarSherlock。 代码运行良好。 唯一的问题是,当抽出导航抽屉时,我无法在应用程序图标旁边切换“上”字样。 我在下面粘贴我的整个代码。 请帮助。

public class MainActivity extends SherlockFragmentActivity { private DrawerLayout mDrawerLayout; private ListView mDrawerList; private ActionBarDrawerToggle mDrawerToggle; private CharSequence mDrawerTitle; private CharSequence mTitle; private String[] mPlanetTitles; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTitle = mDrawerTitle = getTitle(); mPlanetTitles = getResources().getStringArray(R.array.planets_array); mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerList = (ListView) findViewById(R.id.drawer); mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mPlanetTitles)); mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); mDrawerToggle = new ActionBarDrawerToggle(this, /* host Activity */ mDrawerLayout, /* DrawerLayout object */ R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */ R.string.drawer_open, /* "open drawer" description for accessibility */ R.string.drawer_close /* "close drawer" description for accessibility */ ) { public void onDrawerClosed(View view) { getSupportActionBar().setTitle(mTitle); supportInvalidateOptionsMenu(); } public void onDrawerOpened(View drawerView) { getSupportActionBar().setTitle(mDrawerTitle); supportInvalidateOptionsMenu(); } }; getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setHomeButtonEnabled(true); mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { selectItem(0); } new Thread(new Runnable() { @Override public void run() { prefs = getPreferences(MODE_PRIVATE); opened = prefs.getBoolean(OPENED_KEY, false); if(opened == false) { mDrawerLayout.openDrawer(mDrawerList); } } }).start(); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getSupportMenuInflater();

如果你不需要移动3行(如在Gmail应用程序),你可以添加:

 <item name="homeAsUpIndicator">@drawable/ic_drawer</item> <item name="android:homeAsUpIndicator">@drawable/ic_drawer</item> 

在你的活动的主题。 我更喜欢这个在我的应用程序中使用另一个库。

ic_drawer可以从这里下载: http : //developer.android.com/training/implementing-navigation/nav-drawer.html

尝试在切换抽屉上调用syncState,如下所示:

  @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); //your ActionBarDrawerToggle is below mDrawerToggle.syncState(); } 

或者在你实例化之后。

我也有同样的问题,并就这个话题做了一些研究。 在较旧的SDK上正确使用插入符号似乎并不容易。 长话短说,有一个人有一个基于反思的运行示例实现:

我testing了它,即使在Android 2.x上,它也适用于我。

我在4.x设备中删除了插入符,但不是2.x设备。 存储库在这里,如果你需要它: https : //github.com/bcrider/NavigationDrawerSherlocked

这只是Google提供的样例,我已经使用ActionBarSherlock进行了修改。 我解决了一个方法问题(onOptionsItemSelected),最初在ActionBarSherlock被集成到应用程序后阻止了轻敲的图标做任何事情。

希望这可以帮助!
