这是我在导航抽屉菜单项xml代码中的切换

如何设置Listener切换

Answer 1

在准备导航视图菜单项的位置尝试此操作。

NavigationView navigationView=(NavigationView)findViewById(id);

//get the menu from the navigation view
Menu menu=navigationView.getMenu();

//get switch view
SwitchCompat switchcompat=(SwitchCompat) MenuItemCompat.getActionView(menu.findItem(R.id.nav_notify)).findViewById(R.id.drawer_switch);

//add listener
switch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    //your action
                }
            });

Answer 2

您无法使用MenuItemCompat.getActionView（），因为它已弃用

 Menu menu_nav=navigationView.getMenu()
 MenuItem item=menu_nav.findItem(R.id.nav_geolocation);
 switcher=(SwitchCompat)item.getActionView().findViewById(R.id.drawer_switch);

  //add listener
  switch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                //your action
            }
        });

Answer 3

由于不推荐MenuItemCompat.getActionView，所以我使用的代码如下：

MenuItem menuItem = navigationView.getMenu().findItem(R.id.app_bar_switch); // This is the menu item that contains your switch
drawer_switch = (Switch) menuItem.getActionView().findViewById(R.id.drawer_switch);
drawer_switch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // Your logic goes here
        }
});

我希望这可能有用。

Answer 4

菜单布局

<?xml version="1.0" encoding="utf-8"?>
<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:icon="@drawable/ic_notif"
        android:title="Notification"
        app:actionViewClass="android.widget.Switch"
        >
</menu>

代码

val mNavigationView = findViewById(R.id.nav_view)
val navMenu = mNavigationView.menu
val menuItem = navMenu.findItem(R.id.switch)
val switch = menuItem.getActionView() as Switch

switch.setOnCheckedChangeListener { buttonView, isChecked ->
    Toast.makeText(this, "Hello World, isChecked = $isChecked", Toast.LENGTH_LONG).show()
}

如何设置侦听器以在导航抽屉中切换？
