爲什麼在我的活動中有2個標題欄在棉花糖設備中使用導航抽屜

當我在低於棉花糖設備的設備上運行我的應用程序時，它只顯示一個標題欄。但是，當我在棉花糖設備嘗試它時，導航抽屜出現在第二個標題欄中。像這樣。爲什麼在我的活動中有2個標題欄在棉花糖設備中使用導航抽屜

有人能告訴我如何解決這一問題？

我的MainActivity，activity_main，清單和樣式如下。

謝謝。

MainActivity

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { 

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


try { 


    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 

    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    setTitle("Case Sheets"); 

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawer.setDrawerListener(toggle); 
    toggle.syncState(); 

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 

    myDB = MainActivity.this.openOrCreateDatabase("hoteldb", MODE_PRIVATE, null); 

     mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view); 
     RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext()); 
     mRecyclerView.setLayoutManager(mLayoutManager); 
     mRecyclerView.setItemAnimator(new DefaultItemAnimator()); 
     mRecyclerView.addItemDecoration(new DividerItemDecoration(getApplicationContext())); 
     try { 

      showList(); 

     }catch (Exception e) 
     { 
      Toast.makeText(getApplicationContext(),"Please Synch the data",Toast.LENGTH_SHORT).show(); 
     } 



    } catch (Exception e) { 
     e.printStackTrace(); 
     Toast.makeText(getApplicationContext(),"Please Login",Toast.LENGTH_LONG).show(); 
     Intent logout = new Intent(MainActivity.this, LoginPage.class); 
     startActivity(logout); 

    } 



}

我終於修好了。

我所做的是：

1.Deleted從佈局

2.Changed我MainActivity這樣的工具欄。 refer here

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { 

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


try { 


Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 

getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
setTitle("Case Sheets"); 

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
mDrawerToggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) { 
     @Override 
     public void onDrawerClosed(View drawerView) { 
      super.onDrawerClosed(drawerView); 
     } 

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

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
navigationView.setNavigationItemSelectedListener(this); 

myDB = MainActivity.this.openOrCreateDatabase("hoteldb", MODE_PRIVATE, null); 

    mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view); 
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext()); 
    mRecyclerView.setLayoutManager(mLayoutManager); 
    mRecyclerView.setItemAnimator(new DefaultItemAnimator()); 
    mRecyclerView.addItemDecoration(new DividerItemDecoration(getApplicationContext())); 
    try { 

     showList(); 

    }catch (Exception e) 
    { 
     Toast.makeText(getApplicationContext(),"Please Synch the data",Toast.LENGTH_SHORT).show(); 
    } 



} catch (Exception e) { 
    e.printStackTrace(); 
    Toast.makeText(getApplicationContext(),"Please Login",Toast.LENGTH_LONG).show(); 
    Intent logout = new Intent(MainActivity.this, LoginPage.class); 
    startActivity(logout); 

} 



}

，並保持該活動的主題爲Apptheme本身。

它工作在兩個MARSHMELLOW，棒棒糖設備..

工具欄初始化後添加此setSupportActionBar(myToolbar);。

你缺少這樣的：setSupportActionBar()

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
setSupportActionBar(toolbar);

價值觀

/styles.xml：

<style name="AppTheme.NoActionBar"> 
    <item name="windowActionBar">false</item> 
    <item name="windowNoTitle">true</item> 
</style>

應用主題：烏拉圭回合活動清單

在清單：

<activity 
    android:name=".Oodo.CaseSheets.MainActivity" 
    android:theme="@style/AppTheme.NoActionBar" //change here

'java.lang.IllegalStateException：此活動已經有一個由窗口裝飾提供的操作欄。請勿在您的主題中請求Window.FEATURE_SUPPORT_ACTION_BAR並將windowActionBar設置爲false以代替使用工具欄。' – Ben

出現此錯誤。 – Ben

我必須刪除這兩行才能正常工作。 getSupportActionBar（）。setDisplayHomeAsUpEnabled（真）; setSupportActionBar（toolbar）; 現在我不能在marshmellow下面的devies上運行它時看到任何標題欄。 – Ben

爲什麼在我的活動中有2個標題欄在棉花糖設備中使用導航抽屜
