动作栏抽屉切换直到我手动向右滑动以打开导航抽屉时才起作用。在此之后，它会完美响应

Question

问题：当我打开我的应用程序并单击 ActionBarDrawerToggle 时，它不会打开导航抽屉。但是，当我向右滑动然后打开和关闭导航抽屉时，在此之后，ActionBarDrawerToggle 通过打开抽屉可以很好地响应，就像它应该的那样。

我的主屏幕.java

    public class HomeScreen extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
        private Toolbar toolbar;
        private DrawerLayout drawerLayout;
        private NavigationView navigationView;
        private ActionBarDrawerToggle toggle;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.home_screen);
            instantiateViews();
            setSupportActionBar(toolbar);
            navigationView.setNavigationItemSelectedListener(this);
            toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
            drawerLayout.addDrawerListener(toggle);
            toggle.syncState();
    }
        public void instantiateViews(){
                toolbar = findViewById(R.id.drawer_menu_toolbar);
                drawerLayout = findViewById(R.id.home_screen_main_drawer_layout);
                navigationView = findViewById(R.id.home_screen_navigation_view);
            }
    @Override
        public void onBackPressed(){
            if(drawerLayout.isDrawerOpen(GravityCompat.START)){
                drawerLayout.closeDrawer(GravityCompat.START);
            }else {
                super.onBackPressed();
            }
        }
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
            switch (menuItem.getItemId()){
                case R.id.nav_home:
                    break;
                case R.id.nav_account:
                    break;
                case R.id.nav_share:
                    break;
                case R.id.nav_logout:
                    session.logoutUser();
                    break;
            }
            drawerLayout.closeDrawer(GravityCompat.START);
            return true;
        }
}

我已经尝试了以下线程中的所有内容：导航抽屉动作栏按钮不起作用，即使对于那个人来说，动作栏抽屉切换并非在所有情况下都有效，但我的在导航抽屉打开之前不起作用。在那之后，我的工作完美

我尝试过做什么：

1.

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (toggle.onOptionsItemSelected(item)) {
          return true;
        }
        return super.onOptionsItemSelected(item);
    }

阿拉伯数字。

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

3.

toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            drawerLayout.openDrawer(GravityCompat.START);
        }
    });

这些都不适合我

试试这个，或者尝试从相对布局中取出工具栏。

   <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />
    </android.support.design.widget.AppBarLayout>

我对您的布局进行了一些小的修改，希望对您有所帮助。
