Android系統(tǒng)的默認字體很多都不一樣，很多字體都是由手機廠商定制的，下面就讓武林技術頻道小編為大家介紹Android中使用自定義字體的實現方法，希望能幫到您。

1、Android系統(tǒng)默認支持三種字體，分別為：“sans”, “serif”, “monospace

2、在Android中可以引入其他字體。

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:Android="http://schemas.android.com/apk/res/android"
??? Android:layout_width="fill_parent"
??? Android:layout_height="fill_parent" >

??? <TableRow>

??????? <TextView
??????????? Android:layout_marginRight="4px"
??????????? Android:text="sans:"
??????????? Android:textSize="20sp" >
??????? </TextView>
???????

??????? <TextView
??????????? Android:id="@+id/sans"
??????????? Android:text="Hello,World"
??????????? Android:textSize="20sp"
??????????? Android:typeface="sans" >
??????? </TextView>
??? </TableRow>

??? <TableRow>

??????? <TextView
??????????? Android:layout_marginRight="4px"
??????????? Android:text="serif:"
??????????? Android:textSize="20sp" >
??????? </TextView>
???????

??????? <TextView
??????????? Android:id="@+id/serif"
??????????? Android:text="Hello,World"
??????????? Android:textSize="20sp"
??????????? Android:typeface="serif" >
??????? </TextView>
??? </TableRow>

??? <TableRow>

??????? <TextView
??????????? Android:layout_marginRight="4px"
??????????? Android:text="monospace:"
??????????? Android:textSize="20sp" >
??????? </TextView>
???????

??????? <TextView
??????????? Android:id="@+id/monospace"
??????????? Android:text="Hello,World"
??????????? Android:textSize="20sp"
??????????? Android:typeface="monospace" >
??????? </TextView>
??? </TableRow>
???

??? <TableRow>

??????? <TextView
??????????? Android:layout_marginRight="4px"
??????????? Android:text="custom:"
??????????? Android:textSize="20sp" >
??????? </TextView>

??????? <TextView
??????????? Android:id="@+id/custom"
??????????? Android:text="Hello,World"
??????????? Android:textSize="20sp" >
??????? </TextView>
??? </TableRow>

</TableLayout>

// 得到TextView控件對象
TextView textView = (TextView) findViewById(R.id.custom);
// 將字體文件保存在assets/fonts/目錄下，www.linuxidc.com創(chuàng)建Typeface對象
Typeface typeFace = Typeface.createFromAsset(getAssets(),"fonts/DroidSansThai.ttf");
// 應用字體
textView.setTypeface(typeFace);

如果想對整個界面的所有控件都應用自定義字體，可以：

package arui.blog.csdn.net;??

import android.app.Activity;??
import android.graphics.Typeface;??
import android.view.View;??
import android.view.ViewGroup;??
import android.widget.Button;??
import android.widget.EditText;??
import android.widget.TextView;??

public class FontManager {??

??? public static void changeFonts(ViewGroup root, Activity act) {??

?????? Typeface tf = Typeface.createFromAsset(act.getAssets(),??
????????????? "fonts/xxx.ttf");??

?????? for (int i = 0; i < root.getChildCount(); i++) {??
?????????? View v = root.getChildAt(i);??
?????????? if (v instanceof TextView) {??
????????????? ((TextView) v).setTypeface(tf);??
?????????? } else if (v instanceof Button) {??
????????????? ((Button) v).setTypeface(tf);??
?????????? } else if (v instanceof EditText) {??
????????????? ((EditText) v).setTypeface(tf);??
?????????? } else if (v instanceof ViewGroup) {??
????????????? changeFonts((ViewGroup) v, act);??
?????????? }??
?????? }??

??? }??
}?
