Question

我试图在我的激动项目中添加NavigationDrawer，当我运行应用程序并在android studio的设计窗口中时，会出现此错误：

java.lang.IllegalStateException: Child drawer has absolute gravity LEFT but this DrawerLayout already has a drawer view along that edge

我自己试图解决它，但无法找到错误所在的第二个抽屉，为什么我会收到错误？这是xml fileI

以下是MainActivity的OnCreate

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

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


    dbHelper = new DBHelper(this);
    textViewGold = (TextView) findViewById(R.id.textViewGold);
    taskListFragment = (TaskListFragment) getSupportFragmentManager().findFragmentByTag("taskList");
    inventoryFragment = (InventoryFragment) getSupportFragmentManager().findFragmentByTag("inventory");
    loadGuiStuff();

    if (taskListFragment == null)
    {
        taskListFragment = new TaskListFragment();
        transaction = getSupportFragmentManager().beginTransaction();
        transaction.add(R.id.fragmentParentViewGroup, taskListFragment);
        transaction.commit();
    }


}
