     } 

     DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
     drawer.closeDrawer(GravityCompat.START); 
     return true; 
    } 

}

和我有setSupportActionBar(toolbar);
一個錯誤，你能幫我嗎？

請附上您的清單文件 –

看起來你MainActivity主題已經在款式有動作條，設置您的活動主題noActionBar再試試這個setSupportActionBar（工具欄）; –

試試你的活動的父主題設置爲Theme.AppCompat.Light.NoActionBar

的重要組成部分，是「NoActionBar」

然後你就可以在你的佈局中使用自定義ToolBar。

泰克你的建議 –

套裝windowNoTitle和「windowActionBar`在styles.xml的基本主題，並在AndroidManifest.xml這個主題應用到您的應用程序

<!-- Base application theme. --> 
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
     <!-- Customize your theme here. --> 
     <item name="colorPrimary">@color/colorPrimary</item> 
     <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
     <item name="colorAccent">@color/colorAccent</item> 
     <item name="windowNoTitle">true</item> 
     <item name="windowActionBar">false</item> 

    </style>
