將導航抽屜鏈接到工具欄按鈕

Question

我使用的是Navigation Drawer和ActionBarDrawerToggle是同步的，當我通過滑動打開抽屜時，但是當我點擊Toolbar圖標時，它不打開抽屜。 我的代碼有什麼問題。

actionBarDrawerToggle = new ActionBarDrawerToggle(Main2Activity.this, drawerLayout, toolbar, R.string.drawer_open, R.string.close_drawer) { 
     @Override 
     public void onDrawerClosed(View drawerView) { 
      super.onDrawerClosed(drawerView); 
     } 

     @Override 
     public void onDrawerOpened(View drawerView) { 
      super.onDrawerOpened(drawerView); 
     } 
    }; 
    drawerLayout.setDrawerListener(actionBarDrawerToggle); 
    drawerLayout.post(new Runnable() { 
     @Override 
     public void run() { 
      actionBarDrawerToggle.syncState(); 
     } 
    }); 

事情我必須嘗試所以：

actionBar.setDisplayHomeAsUpEnabled(true); 
    @Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     case android.R.id.home: 
      drawerLayout.openDrawer(Gravity.START); 
      return true; 
    } 

    return super.onOptionsItemSelected(item); 
} 

這是我的佈局，我已經使用。我有NavigationView和抽屜佈局。

     </LinearLayout>

那麼請問，現在的問題在哪裏？

感謝所有我已解決我的問題。這個問題實際上並不在代碼中，但問題出在Layout中，我添加了一個TabHost，它不允許單擊工具欄，所以這是實際的問題。

Answer 1

創建toolbar.xml：

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v7.widget.Toolbar 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:background="@color/toolbar" 
    android:minHeight="?attr/actionBarSize" 
    android:fitsSystemWindows="true" 
    > 

</android.support.v7.widget.Toolbar> 

創建drawer_menu.xml：

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android"> 

    <group 
     android:checkableBehavior="single" 
     android:id="@+id/first_group"> 

     <item 
      android:id="@+id/first_item" 
      android:title="First Item" 
      android:icon="@drawable/first_item" 
      /> 

    </group> 

    <group 
     android:checkableBehavior="single" 
     android:id="@+id/second_group"> 
     <item 
      android:id="@+id/second_item" 
      android:title="Second Item" 
      android:icon="@drawable/second_item"> 

     </item> 
    </group> 

</menu> 

那麼你的活動格式應該是這樣的：

<?xml version="1.0" encoding="utf-8"?> 
    <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:id="@+id/drawer_layout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     tools:context=".MainActivity"> 

     <!--First child represents elements of activity in drawerLayout--> 

     <RelativeLayout 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:orientation="vertical" 
      android:id="@+id/relative_layout"> 

      <include 
       android:id="@+id/toolbar" 
       layout="@layout/toolbar" 
       /> 

     </RelativeLayout> 

     <!--Second child (navigation view) represents elements of navigation drawer in drawerLayout--> 

     <android.support.design.widget.NavigationView 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:id="@+id/navigation_view" 
      android:layout_gravity="start" 
      android:background="@color/toolbar" 
      app:menu="@menu/drawer_menu"> 

     </android.support.design.widget.NavigationView> 

    </android.support.v4.widget.DrawerLayout> 

對於漢堡包圖標：

drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 

actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close); 

drawerLayout.addDrawerListener(actionBarDrawerToggle); 

，然後創建一個方法：

@Override 
protected void onPostCreate(Bundle savedInstanceState) { 
    super.onPostCreate(savedInstanceState); 
    actionBarDrawerToggle.syncState(); 
} 

讓我知道，如果它幫助。
