实现步骤
原生替换字体
1.创建MyApplication并在AndroidManifest中引用
<application
android:name=".MyApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".WebViewActivity"></activity>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
2.自定义application的theme设置默认字体为monospace
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<!-- 设置默认字体为monospace -->
<item name="android:typeface">monospace</item>
</style>
3.在MyApplication中利用反射替换字体
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
changeTTF();
}
private void changeTTF() {
Typeface typefaceALTAN = Typeface.createFromAsset(getAssets(), "fonts/ALTAN.TTF");
try {
Field typefaceField = Typeface.class.getDeclaredField("MONOSPACE");
typefaceField.setAccessible(true);
typefaceField.set(null,typefaceALTAN);
}catch (Exception e){}
}
}
本地网页替换字体
在样式中定义字体，然后将所有标签的字体改为自己定义的那个即可
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style>
@font-face {
font-family:'ALTAN';
src: url("file:///android_asset/fonts/ALTAN.TTF");
}
*{
font-family: 'ALTAN';
}
</style>
</head>
<body>
<p>Hello World</p>
<h1>Hello World</h1>
</body>
</html>
最后要注意这里的字体文件和本地网页都放在了assets文件夹下
