【中文标题】导航抽屉操作栏按钮不起作用【英文标题】:Navigation Drawer ActionBar button not working 【发布时间】:2013-05-20 15:31:53 【问题描述】:我正在开发一个 android 项目,我正在尝试使用来自 http://developer.android.com/training/implementing-navigation/nav-drawer.html 的示例集成新的 Navigation Drawer。
它主要工作除了一件事,操作栏向上按钮不显示菜单,但如果我从边缘在主活动屏幕上滑动手指,然后菜单出现,所以我知道没有任何问题实际的菜单,它只是操作栏按钮。
下面是代码
public class MainActivity extends Activity
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mTitle;
private CharSequence mDrawerTitle;
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.left_drawer);
MenuItemAdapter menuAdapter = new MenuItemAdapter(this);
menuAdapter.add(new MenuItem("Hello"));
menuAdapter.add(new MenuItem("World"));
menuAdapter.add(new MenuItem("Parsnips"));
menuAdapter.add(new MenuItem("Turnips"));
mDrawerList.setAdapter(menuAdapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_closed)
public void onDrawerClosed(View view)
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
public void onDrawerOpened(View drawerView)
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
;
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null)
selectItem(0);
@Override
public boolean onCreateOptionsMenu(Menu menu)
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
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)
// update the main content by replacing fragments
android.app.Fragment fragment = new PlanetFragment();
Bundle args = new Bundle();
args.putInt(PlanetFragment.ARGS_PLANET_NUMBER, position);
fragment.setArguments(args);
android.app.FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
@Override
public void setTitle(CharSequence title)
mTitle = title;
getActionBar().setTitle(mTitle);
@Override
protected void onPostCreate(Bundle savedInstanceState)
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
@Override
public void onConfigurationChanged(Configuration newConfig)
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
public static class PlanetFragment extends android.app.Fragment
public static final String ARGS_PLANET_NUMBER = "planet_number";
public PlanetFragment()
@Override
public View onCreateView(LayoutInflater inflator, ViewGroup container, Bundle savedInstanceState)
View rootView = inflator.inflate(R.layout.fragment_planet, container, false);
int i = getArguments().getInt(ARGS_PLANET_NUMBER);
String planet = getResources().getStringArray(R.array.planets_array)[i];
//((TextView)rootView.findViewById(R.id.fragment_text_view)).setText(planet);
getActivity().setTitle("Planet: " + planet);
return rootView;
private class MenuItem
public String menuName;
public MenuItem(String menuName)
this.menuName = menuName;
public class MenuItemAdapter extends ArrayAdapter<MenuItem>
public MenuItemAdapter (Context context)
super(context,0);
public View getView (int position, View convertView, ViewGroup parent)
convertView = null;
if (convertView == null)
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row_menu_item, null);
/*TextView title = (TextView)convertView.findViewById(R.id.row_title);
title.setText(getItem(position).menuName);
title.setVisibility(View.VISIBLE);*/
EditText title = (EditText)convertView.findViewById(R.id.row_edittext);
title.setHint(getItem(position).menuName);
title.setVisibility(View.VISIBLE);
return convertView;
感谢您提供的任何帮助。
【问题讨论】:
【参考方案1】:你忘了实现 onOptionsItemSelected
这就是神奇发生的地方:
@Override
public boolean onOptionsItemSelected(MenuItem item)
// Pass the event to ActionBarDrawerToggle, if it returns
// true, then it has handled the app icon touch event
if (mDrawerToggle.onOptionsItemSelected(item))
return true;
// Handle your other action bar items...
return super.onOptionsItemSelected(item);

谢谢,我不知道有多少次我仔细检查了文档并且每次都设法错过了。感谢您的帮助 如果我不想要上面的操作栏怎么办,那我可以不包括上面提到的代码吗? 哇...节省了我的时间 我傻眼了,因为我的工作,然后没有,但这是因为我删除了这个方法没有注意,因为我删除了我的操作栏项目...... @TintinabulatorZea 你还是错过了一些东西。您需要覆盖onPostCreate()
并添加actionBarDrawerToggle.syncState();
【参考方案2】:
对于那些仍然有问题的人,你可能错过了这个方法(OP有但我已经删除了):
@Override
protected void onPostCreate(Bundle savedInstanceState)
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
【讨论】:
在onPostCreate
中调用它真的很重要。在onCreate
中调用它是行不通的!谢谢老哥
这带来了我正在寻找的汉堡图标。谢谢:)【参考方案3】:
它对我有用。
drawerToggle.setToolbarNavigationClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
mDrawer.openDrawer(GravityCompat.START);
);

【参考方案4】:在这里,我将告诉您在不使用 android studio 的情况下在 android 中创建抽屉导航的简单方法。我刚刚使用 ADT 创建导航抽屉。 下面是代码看看
activity_main.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/dr_layout"
android:layout_
android:layout_>
<RelativeLayout
android:id="@+id/mainContent"
android:layout_
android:layout_>
<TextView
android:id="@+id/txt1"
android:layout_
android:layout_
android:text="swipe content"/>
<Button
android:id="@+id/bt1"
android:layout_
android:layout_
android:text = "Click to open d"/>
</RelativeLayout>
<RelativeLayout
android:id="@+id/drawer"
android:layout_
android:layout_
android:layout_gravity = "start"
android:background="#FFFFFF">
<TextView
android:id="@+id/txt2"
android:layout_
android:layout_
android:text="drawer content are here arr"/>
<Button
android:id="@+id/bt2"
android:layout_
android:layout_
android:text = "Click to open d"/>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>

import android.view.MotionEvent;
import android.view.View;

import android.widget.Toast;
public class MainActivity extends Activity
private DrawerLayout drawerLayout;
private View drawerView;
Button bt1,bt2;
private DrawerListener myDrawerListner;
private ActionBarDrawerToggle mDrawerTogle;
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
drawerLayout = (DrawerLayout) findViewById(R.id.dr_layout);
drawerView = (View) findViewById(R.id.drawer);
drawerLayout.setDrawerListener(myDrawerListner);
bt1 = (Button) findViewById(R.id.bt1);
bt2 = (Button) findViewById(R.id.bt2);
mDrawerTogle =new ActionBarDrawerToggle(this, drawerLayout,
R.drawable.ic_drawer,R.string.open_drawer,R.string.close_drawer)
public void onDrawerOpened(View drawerView)
// TODO Auto-generated method stub
super.onDrawerOpened(drawerView);
getActionBar().setTitle("SpeakEng");
public void onDrawerClosed(View view)
// TODO Auto-generated method stub
super.onDrawerClosed(view);
getActionBar().setTitle("SpeakEng");
;
drawerLayout.setDrawerListener(mDrawerTogle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
bt2.setOnClickListener(new OnClickListener()
@Override
public void onClick(View arg0)
// TODO Auto-generated method stub
drawerLayout.closeDrawer(drawerView);
);
bt1.setOnClickListener(new OnClickListener()
@Override
public void onClick(View arg0)
// TODO Auto-generated method stub
drawerLayout.openDrawer(drawerView);
);
@Override
public void onConfigurationChanged(Configuration newConfig)
super.onConfigurationChanged(newConfig);
mDrawerTogle.onConfigurationChanged(newConfig);
public boolean onOptionsItemSelected(MenuItem item)
if (mDrawerTogle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
@Override
protected void onPostCreate(Bundle savedInstanceState)
super.onPostCreate(savedInstanceState);
//Sync the toogle state after onRestoreInstanceState has occured.
mDrawerTogle.syncState();
您可以打开抽屉 1)通过单击按钮,2)从左侧拉,3)单击操作栏上的抽屉图标。您可以根据需要打开它。我给了您三个选项。
注意:drawerLayout 必须是根元素,如代码所示。 并保持 onConfigurationChanged()、onOptionsItemSelected()、onPostCreate()。 这三个方法对于创建抽屉式导航非常重要。
祝你好运!
