Android设置本地字体文件ttf

本文介绍: 产品告诉UI设计设计图时要使用炫酷字体。因为And roid不像网页项目可以使用浏览器本机的字体，And roid只有那几种字体。


import android.content.Context
import android.graphics.Typeface

object FontsOverride {

/**
*staticTypefaceFieldName :最好是 normal、sans、serif、monospace其中一个
*/
    fun setDefaultFont(context: Context, staticTypefaceFieldName: String, fontAssetName: String?) {
        val regular = Typeface.createFromAsset(context.assets, fontAssetName)
        replaceFont(staticTypefaceFieldName, regular)
    }

    internal fun replaceFont(staticTypefaceFieldName: String, newTypeface: Typeface?) {
        try {
            val staticField = Typeface::class.java.getDeclaredField(staticTypefaceFieldName)
            staticField.isAccessible = true
            staticField[null] = newTypeface
        } catch (e: NoSuchFieldException) {
            e.printStackTrace()
        } catch (e: IllegalAccessException) {
            e.printStackTrace()
        }
    }
}

//staticTypefaceFieldName :最好是 normal、sans、serif、monospace其中一个
FontsOverride.setDefaultFont(this, "SERIF", "fonts/pangmenzhengdaobiaoti.ttf")

代码如下（示例）：

    <TextView
                android:id="@+id/newHomeLoction" 
                android:textColor="@color/white"
                android:textSize="26sp"
                android:typeface="serif"
                app:layout_constraintStart_toStartOf="@+id/newHomeLeaveTitle"
                app:layout_constraintTop_toBottomOf="@+id/newHomeLeaveTitle" />

        <TextView
                android:id="@+id/newHomeLoction"
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1"
                android:gravity="bottom|end"
                android:includeFontPadding="false"
                android:paddingBottom="28dp"
                android:fontFamily="@font/pangiaoti"
                android:text="字体水水水水" />
