如何在新的NavigationView中添加自定义视图

Question

我想一个开关添加为菜单项NavigationView这样

我使用了actionViewClass属性,但它只显示标题.

<item
android:id="@+id/navi_item_create_notifications_sound"
android:title="Notifications Sounds"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:actionViewClass="android.support.v7.widget.SwitchCompat"
app:showAsAction="always" />

Answer 1

新的支持库23.1

允许使用app:actionLayout或使用MenuItemCompat.setActionView()在导航视图中为项目使用自定义视图

这是我设法显示SwitchCompat的方法

menu_nav.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group
        android:id="@+id/first"
        android:checkableBehavior="single">

        <item
            android:id="@+id/navi_item_1"
            android:icon="@drawable/ic_feed_grey_500_24dp"
            android:title="Feed" />
        <item
            android:id="@+id/navi_item_2"
            android:icon="@drawable/ic_explore_grey_500_24dp"
            android:title="Explore" />
        <item
            android:id="@+id/navi_item_4"
            android:icon="@drawable/ic_settings_grey_500_24dp"
            android:title="Settings" />

    </group>
    <group
        android:id="@+id/second"
        android:checkableBehavior="single">
        <item xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/navi_item_create_notifications_sound"
            android:title="Notifications Sounds"
            app:actionLayout="@layout/menu_swich"
            app:showAsAction="always" />

    </group>
</menu>

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SwitchCompat xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:gravity="right|center_vertical"
    app:buttonTint="@color/colorPrimary"
    app:switchPadding="@dimen/spacing_small" />

menu_switch.xml

SwitchCompat item = (SwitchCompat) navigationView.getMenu().getItem(3).getActionView();
        item.setOnCheckedChangeListener( new CompoundButton.OnCheckedChangeListener(){
            @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                Logr.v(LOG_TAG, "onCheckedChanged" + isChecked);
            }
        });

要获取视图并为其分配事件,您应该:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group
        android:id="@+id/first"
        android:checkableBehavior="single">

        <item
            android:id="@+id/navi_item_1"
            android:icon="@drawable/ic_feed_grey_500_24dp"
            android:title="Feed" />
        <item
            android:id="@+id/navi_item_2"
            android:icon="@drawable/ic_explore_grey_500_24dp"
            android:title="Explore" />
        <item
            android:id="@+id/navi_item_4"
            android:icon="@drawable/ic_settings_grey_500_24dp"
            android:title="Settings" />

    </group>
    <group
        android:id="@+id/second"
        android:checkableBehavior="single">
        <item xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/navi_item_create_notifications_sound"
            android:title="Notifications Sounds"
            app:actionLayout="@layout/menu_swich"
            app:showAsAction="always" />

    </group>
</menu>

您正在使用的简单解决方案 NavigationView

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:menu="@menu/activity_main_drawer">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:orientation="horizontal">

        <android.support.v7.widget.SwitchCompat
            android:id="@+id/mSwitch"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:text="Night Mode" />

    </LinearLayout>

</android.support.design.widget.NavigationView>
