Question

画出红线以显示橙色线应继续前进的地方。

搜索类似的问题后，我找不到解决问题的方法。我有一个切换按钮显示在我的活动中，但是当我按下它时，它不会打开导航抽屉（如果我滑动手指会打开它）。

*活动中显示切换按钮（工具栏为透明）

OnCreate和onOptionsItemSelect

ActionBarDrawerToggle toggle;
DrawerLayout drawer;
NavigationView navigationView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.my_toolbar);
    setSupportActionBar(toolbar);

    drawer = findViewById(R.id.drawer_layout);

    toggle = new ActionBarDrawerToggle
            (
                    this,
                    drawer,
                    R.string.navigation_drawer_open,
                    R.string.navigation_drawer_close
            )
    {
    };

    drawer.addDrawerListener(toggle);
    toggle.syncState();
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setTitle("");
    toggle.getDrawerArrowDrawable().setColor(getResources().getColor(R.color.colorPrimaryDark));

    FloatingActionButton fab =   findViewById(R.id.action_btn);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(getApplicationContext(), NewEventActivity.class);
            startActivity(intent);
            /*Intent intent = new Intent(getApplicationContext(), testes.class);
            startActivity(intent);*/

        }
    });

    navigationView = findViewById(R.id.navigation_view);
    navigationView.setNavigationItemSelectedListener(this);

}

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

    return super.onOptionsItemSelected(item);
}
