导航抽屉选择零索引位置而不是其他位置

Question

I am creating an application in which I want to navigate different activities on the basis of selection of list view available drawer but it is just selecting zero position of list view and not even working other position number I tried a lot but no idea how to deal with it here is the code...

  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;
        case 3:
            drawerIntent = new Intent(NowPlaying.this,Store.class);
            startActivity(drawerIntent);
            break;
        case 4:
            drawerIntent = new Intent(NowPlaying.this,Scan.class);
            startActivity(drawerIntent);
            break;
    }*/

    mDrawerLayout.closeDrawer(mDrawerList);
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    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,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.store, container, false);
    return rootView;
}

} }

Answer 1

What actually logcat says?? And i have seen that you have commented out your switch portion..Another observation is that as you are using sliding drawer i think you need that drawer as you go further into your app.But you are using intent after clicking one option.You must use fragment .You can see this link to learn slidingdrawer.I thing you can implement like this.

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);
                // calling onPrepareOptionsMenu() to hide action bar icons
                invalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        }
