您好,我正在使用 minSDKVersion 8 到 17 使用 Android Navigation Drawer。在程序中,我正在使用操作栏组件来工作导航抽屉。每当在 4.1v android 设备中运行程序时,它都会成功运行,但是当我尝试在 2.3v android 设备中运行相同的程序时,它会显示异常。这是我的详细片段。

MainActivity.java

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public class MainActivity extends ActionBarActivity{

    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ActionBarDrawerToggle mDrawerToggle;

    private CharSequence mDrawerTitle;
    private CharSequence mTitle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTitle = mDrawerTitle = "Event Option";//getTitle();
        mEventOptions = getResources().getStringArray(R.array.event_options);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.left_drawer);

        // set a custom shadow that overlays the main content when the drawer opens
        mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
        // set up the drawer's list view with items and click listener
        mDrawerList.setAdapter(new ArrayAdapter<String>(this,
                R.layout.drawer_list_item, mEventOptions));
        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

        // enable ActionBar app icon to behave as action to toggle nav drawer
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);

        // between the sliding drawer and the action bar app icon

用 替换所有出现getFragmentManagergetSupportFragmentManager。您可能需要相应地替换应用程序的其他部分。
