如何在Android中更改TextView的fontFamily

所以我想在android中更改android:fontFamily，但我在android中没有看到任何预定义的字体。如何选择预定义的选项之一？我真的不需要定义我自己的TypeFace，但我所需要的是与现在显示的不同。

<TextView
    android:id="@+id/HeaderText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="52dp"
    android:gravity="center"
    android:text="CallerBlocker"
    android:textSize="40dp"
    android:fontFamily="Arial"
 />

看来我在上面做的事真的行不通！BTW android:fontFamily=“Arial”是一个愚蠢的尝试！

从android 4.1/4.2/5.0开始，以下Roboto字体系列可用：

android:fontFamily="sans-serif"           // roboto regular
android:fontFamily="sans-serif-light"     // roboto light
android:fontFamily="sans-serif-condensed" // roboto condensed
android:fontFamily="sans-serif-black"     // roboto black
android:fontFamily="sans-serif-thin"      // roboto thin (android 4.2)
android:fontFamily="sans-serif-medium"    // roboto medium (android 5.0)

与

android:textStyle="normal|bold|italic"

管理字体的一种简单方法是通过资源声明它们，例如：

<!--++++++++++++++++++++++++++-->
<!--added on API 16 (JB - 4.1)-->
<!--++++++++++++++++++++++++++-->
<!--the default font-->
<string name="fontFamily__roboto_regular">sans-serif</string>
<string name="fontFamily__roboto_light">sans-serif-light</string>
<string name="fontFamily__roboto_condensed">sans-serif-condensed</string>

<!--+++++++++++++++++++++++++++++-->
<!--added on API 17 (JBMR1 - 4.2)-->
<!--+++++++++++++++++++++++++++++-->
<string name="fontFamily__roboto_thin">sans-serif-thin</string>

<!--+++++++++++++++++++++++++++-->
<!--added on Lollipop (LL- 5.0)-->
<!--+++++++++++++++++++++++++++-->
<string name="fontFamily__roboto_medium">sans-serif-medium</string>
<string name="fontFamily__roboto_black">sans-serif-black</string>
<string name="fontFamily__roboto_condensed_light">sans-serif-condensed-light</string>

这是基于这里和这里的源代码

试试看：

TextView textview = (TextView) findViewById(R.id.textview);
Typeface tf= Typeface.createFromAsset(getAssets(),"fonts/Tahoma.ttf");
textview .setTypeface(tf);

以编程方式将字体添加到TextView的最简单方法是，首先，将字体文件添加到项目中的“资产”文件夹中。例如，字体路径如下所示：assets/fonts/my_font.otf

并将其添加到TextView中：

科特林

val font_path = "fonts/my_font.otf"  

myTypeface = Typeface.createFromAsset(MyApplication.getInstance().assets, font_path)

textView.typeface = myTypeface

Java

String font_path = "fonts/my_font.otf";
Typeface myTypeface = Typeface.createFromAsset(MyApplication.getInstance().assets, font_path)
textView.setTypeface(myTypeface);
