Question

我想将左上角的默认DrawerLayout图标更改为我自己的图像，但我不知道为什么它在app的加载时不起作用。仅当我打开或关闭侧边菜单时，图标才会更改。我也想禁用动画，在我更改图标后它被禁用但只有在打开和关闭后才会发生。我不知道为什么这对活动的加载不起作用

actionBar = (Toolbar) findViewById(R.id.custom_screen_toolbar);

    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    drawerToggle = new ActionBarDrawerToggle(this, /* host Activity */
    drawerLayout, actionBar, R.string.drawer_open, R.string.drawer_close) {

        /** Called when a drawer has settled in a completely closed state. */
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            actionBar.setTitle("Nav Menu Close");
            actionBar.setNavigationIcon(R.drawable.action_bar_menu);
        }

        /** Called when a drawer has settled in a completely open state. */
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            actionBar.setTitle("Nav Menu Open");
            actionBar.setNavigationIcon(R.drawable.action_bar_back_icon);
        }
    };

    // Set the drawer toggle as the DrawerListener
    drawerLayout.setDrawerListener(drawerToggle);
    actionBar.setSubtitleTextColor(getResources().getColor(
            R.color.light_gray));
    actionBar.setBackgroundResource(R.drawable.divider_action_bar);
    actionBar.setNavigationIcon(R.drawable.action_bar_menu);

    setSupportActionBar(actionBar);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

Answer 1

我相信调用setDisplayHomeAsUpEnabled(true)会导致导航图标设置为后退箭头图标，此外还提供了在选择活动时完成活动的默认行为。

您应该能够删除该行并setHomeButtonEnabled(true)以获得所需的效果。
