導航抽屜選擇零索引位置而不是其他位置

Question

我正在創建一個應用程序，我希望在選擇列表視圖可用抽屜的基礎上導航不同的活動，但它只是選擇列表視圖的零位置，甚至沒有工作其他位置編號我嘗試了很多但不知道如何處理這里有代碼......

  public class NowPlaying extends Activity {

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

  private CharSequence mDrawerTitle;
  private CharSequence mTitle;
  private String[] mPlanetTitles;
  Intent drawerIntent;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.now_playing);

    mTitle = mDrawerTitle = getTitle();
    mPlanetTitles = getResources().getStringArray(R.array.playing_now_list);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.left_drawer);

                 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, mPlanetTitles));
    mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

    mDrawerToggle = new ActionBarDrawerToggle(
            this,
            mDrawerLayout,
            R.drawable.ic_drawer,
            R.string.drawer_open,
            R.string.drawer_close
    ) {
        public void onDrawerClosed(View view) {
           // getActionBar().setTitle(mTitle);
            invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        }

        public void onDrawerOpened(View drawerView) {
         //   getActionBar().setTitle(mDrawerTitle);
            invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        }
    };
    mDrawerLayout.setDrawerListener(mDrawerToggle);

    if (savedInstanceState == null) {
        selectItem(0);
    }
}
public boolean onPrepareOptionsMenu(Menu menu) {

    boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
    //menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
    return super.onPrepareOptionsMenu(menu);
}



private class DrawerItemClickListener implements ListView.OnItemClickListener {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
      selectItem(position);

    }
}
private void selectItem(int position) {

    mDrawerList.setItemChecked(position, true);



    /*switch(position){

        case 0:
           drawerIntent = new Intent(NowPlaying.this,MainActivity.class);
           startActivity(drawerIntent);
           break;
        case 1:
            drawerIntent = new Intent(NowPlaying.this,Artist.class);
            startActivity(drawerIntent);
            break;
        case 2:
        drawerIntent = new Intent(NowPlaying.this,Favorites.class);
        startActivity(drawerIntent);
        break;

            startActivity(drawerIntent);
            break;
    }*/

    mDrawerLayout.closeDrawer(mDrawerList);
}

@Override

    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    // Pass any configuration change to the drawer toggls
    mDrawerToggle.onConfigurationChanged(newConfig);
}

public static class PlanetFragment extends Fragment {

public PlanetFragment() {

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

實際上logcat說什么？ 我已經看到你已經注釋掉了你的開關部分。另一個觀察是，當你使用滑動抽屜時，我認為你需要那個抽屜，因為你進一步進入你的應用程序。但是你在點擊一個選項后使用意圖。你必須使用fragment 。你可以看到這個鏈接來學習slidedrawer。我可以像這樣實現。

My code:

public class SlidingDrawerActivity extends ActionBarActivity {
    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ActionBarDrawerToggle mDrawerToggle;
    private LinearLayout mDrawerLinear;
    private TextView profile_name;
    public ArrayList <Search> searchData;
    private ImageView profilePic;
    public int Count;
    // nav drawer title
    private CharSequence mDrawerTitle;

    Fragment fragment = null;

    // used to store app title
    private CharSequence mTitle;

    // slide menu items
    private String[] navMenuTitles;
    private TypedArray navMenuIcons;

    private ArrayList<NavDrawerItem> navDrawerItems;
    private NavDrawerListAdapter adapter;

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

        //initializing profile_name
        profile_name = (TextView) findViewById(R.id.profile_name);
        profilePic = (ImageView) findViewById(R.id.profile_image);

        String profileName = getIntent().getExtras().getString(PropertyNames.Userinfo_Username.getProperty());
        profile_name.setText(profileName);

        String imageString = getIntent().getExtras().getString(PropertyNames.Userinfo_Profilepic.getProperty());
        if(imageString != null)
            profilePic.setImageBitmap(ImageConverter.stringToimageConverter(imageString));

        mTitle = mDrawerTitle = getTitle();

        // load slide menu items
        navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);

        // nav drawer icons from resources
        navMenuIcons = getResources()
                .obtainTypedArray(R.array.nav_drawer_icons);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerLinear = (LinearLayout) findViewById(R.id.left_drawer);
        mDrawerList = (ListView) findViewById(R.id.list_slidermenu);

        navDrawerItems = new ArrayList<NavDrawerItem>();

        // adding nav drawer items to array

        navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[6], navMenuIcons.getResourceId(6, -1)));
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[7], navMenuIcons.getResourceId(7, -1)));


        // Recycle the typed array
        navMenuIcons.recycle();

        // setting the nav drawer list adapter
        adapter = new NavDrawerListAdapter(getApplicationContext(),
                navDrawerItems);
        mDrawerList.setAdapter(adapter);





        // enabling action bar app icon and behaving it as toggle button
        // getActionBar().setDisplayHomeAsUpEnabled(true);
        //getActionBar().setHomeButtonEnabled(true);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_toggle, //nav menu toggle icon
                R.string.app_name, // nav drawer open - description for accessibility
                R.string.app_name // nav drawer close - description for accessibility
        ) {
            public void onDrawerClosed(View view) {
                //getActionBar().setTitle(mTitle);
                // calling onPrepareOptionsMenu() to show action bar icons
                invalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {
                //getActionBar().setTitle(mDrawerTitle);
