如何更改 SwitchCompat 的字体系列？

Question

I've noticed that the SwitchCompat's font does not seem to change with what I've set in the fontFamily field. I've also tried using styles with custom fontFamily ( which works on TextViews ) and even the switchTextAppearance field. It does apply on the preview ( I know the preview is not really accurate ) but not when I tried running it on my test device.

Here's my SwitchCompat:

<android.support.v7.widget.SwitchCompat
            style="@style/MyStyle.Body"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fontFamily="@font/my_font_family"
            android:text="Enable"
            app:switchTextAppearance="@style/MyStyle.Body"/>

and here's my style:

<style name="MyStyle.Body" parent="Base.TextAppearance.AppCompat.Body1">
    <item name="android:textSize">14sp</item>
    <item name="android:fontFamily">@font/my_font_family</item>
    <item name="android:textColor">@color/color_primary_text</item>
</style>

As you can see, I only really want to change it's font

EDIT

I've changed my style to this

<style name="MyStyle.Switch" parent="Widget.AppCompat.CompoundButton.Switch">
    <item name="android:textSize">14sp</item>
    <item name="android:textColor">@color/color_primary_text</item>
    <item name="android:fontFamily">@font/my_font_family</item>
    <item name="fontFamily">@font/my_font_family</item>
</style>

still doesn't work though

Answer 1

XML 设置不起作用，因此我使用以下代码：

someSwitch.setTypeface(ResourcesCompat.getFont(context, R.font.roboto));

Answer 2

Try

parent="Base.TextAppearance.AppCompat.Body1"

replace into this

parent="TextAppearance.AppCompat.Widget.Switch"

Answer 3

Try below

public class CustomSwitchCompact extends SwitchCompat {

    public CustomSwitchCompact(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public CustomSwitchCompact(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public CustomSwitchCompact(Context context) {
        super(context);
        init();
    }

    private void init() {
        if (!isInEditMode()) {
            Typeface myFonts = Typeface.createFromAsset(getContext().getAssets(),
                    "fonts/Roboto_Bold.ttf");
            setTypeface(myFonts);
        }
    }
}

XML file

<com.test.CustomSwitchCompact
        android:id="@+id/switch_compat"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:checked="false"
        android:padding="20dp"
        android:text="SwitchCompat"
        android:textOff="OFF"
        android:textOn="ON"
        app:showText="true" />

Another way to achieve SwitchCompact with custom font

  <android.support.v7.widget.SwitchCompat
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/adamSwitch"
        android:textColor="@color/top_color"
        android:textAppearance="@color/top_color"
        android:gravity="center"
        app:showText="true"
        android:fontFamily="@font/my_font_family"
        app:theme="@style/Custom.Widget.SwitchCompat"
        app:switchPadding="5dp"
        />

in style.xml

<style name="Custom.Widget.SwitchCompat" parent="Widget.AppCompat.CompoundButton.Switch" >
            <item name="android:textColorPrimary">@color/blue</item>  
            <item name="android:textSize">14sp</item>
            <item name="android:fontFamily">@font/my_font_family</item>
             <item name="android:textColor">@color/color_primary_text</item>
      </style>

Answer 4

唯一对我setSwitchTypeface是setSwitchTypeface ，而不是setTypeface ：

    my_switch.setSwitchTypeface(ResourcesCompat.getFont(context, R.font.my_font))

Answer 5

I've used android:textAppearance instead of android:switchTextAppearance and custom font works now. Also my switch style have Widget.AppCompat.CompoundButton.Switch as parent
