我想在应用程序中使用滑动导航抽屉。但是，它似乎没有处理OnItemClick方法。当我点击一个项目什么我happens.How使它发挥作用？谢谢

// MainActivity

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

    drawer_layout = (DrawerLayout)findViewById(R.id.drawerLayout); 
    list_view = (ListView)findViewById(R.id.drawerList); 
    menu_items = getResources().getStringArray(R.array.nav_drawer_items); 
    list_view.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, menu_items)); 
    list_view.setOnItemClickListener(this); 

} 

@Override 
public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
    // TODO Auto-generated method stub 



     Toast.makeText(MainActivity.this, menu_items[position] + " was selected", Toast.LENGTH_LONG).show(); 

}

Answer 1

你DrawerLayout的孩子View小号不正确的z顺序。抽屉的View - 在这种情况下，ListView - 需要最后列出才能成为其他任何东西的首选。

Answer 2

对于左侧菜单中的抽屉完成简单的，你可以试试下面的简单....

MainActivity.class

private DrawerLayout mDrawerLayout; 
private ListView mDrawerList; 
private ActionBarDrawerToggle mDrawerToggle; 
private CharSequence mDrawerTitle; 
private CharSequence mTitle; 
private String[] navMenuTitles; 
private ArrayList<MainDrawerItem> navDrawerItems; 
private NavDrawerListAdapter adapter; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    // for lefdrawer 
    mTitle = mDrawerTitle = getTitle(); 

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

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_dashboard_layout); 
    mDrawerList = (ListView) findViewById(R.id.main_dash_left_list_drawer); 
    navDrawerItems = new ArrayList<MainDrawerItem>(); 
    navDrawerItems.add(new MainDrawerItem(navMenuTitles[0], 0, 
      null, false)); 
     mDrawerList.setOnItemClickListener(new SlideMenuClickListener()); 

    // 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_drawer, // 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); 

    if (savedInstanceState == null) { 
     // on first time display view for first nav item 
     displayView(0); 
    } 
private void displayView(int position) { 
    // update the main content by replacing fragments 
    switch (position) { 
    case 0: 

    Toast.makeText(MainActivity.this, ..... + " was selected",Toast.LENGTH_LONG).show(); 
     break; 
    default: 

     break; 
} 
} 

private class SlideMenuClickListener implements 
     ListView.OnItemClickListener { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, 
      long id) { 
     // display view for selected nav drawer item 
     displayView(position); 
    } 
} 

    @Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // toggle nav drawer on selecting action bar app icon/title 
    if (mDrawerToggle.onOptionsItemSelected(item)) { 
     return true; 
    } 
    // Handle action bar actions click 
    switch (item.getItemId()) { 
    case R.id.action_settings: 
     return true; 
    default: 
     return super.onOptionsItemSelected(item); 
    } 
} 

MainDrawerItem.class

public class MainDrawerItem { 
private String title; 
public MainDrawerItem(){ 
} 

public MainDrawerItem(String title){ 
    this.title = title; 

} 

public String getTitle(){ 
    return this.title; 
} 
} 

对于适配器类别

public class NavDrawerListAdapter extends BaseAdapter { 

private Context context; 
private ArrayList<MainDrawerItem> navDrawerItems; 

public NavDrawerListAdapter(Context context, ArrayList<MainDrawerItem> navDrawerItems){ 
    this.context = context; 
    this.navDrawerItems = navDrawerItems; 
} 
@Override 
public Object getItem(int position) {  
    return navDrawerItems.get(position); 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    if (convertView == null) { 
     LayoutInflater mInflater = (LayoutInflater) 
       context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     convertView = mInflater.inflate(R.layout.drawer_list_item, null); 
    } 

    TextView txtTitle = (TextView) convertView.findViewById(R.id.title);  
    txtTitle.setText(navDrawerItems.get(position).getTitle()); 

    return convertView; 
} 

}
