本文介绍了两种在Android中自定义TextView字体的方法：一种是直接在代码中设置，另一种是创建自定义字体TextView基类，并在XML布局中使用。通过在assets/fonts目录下放置字体文件，然后使用Typeface类加载，可以轻松更改应用中的字体样式。

两种方法：

方法一:

在assets目录下新建目录fonts，然后存放自己的字体库，我这里是微软雅黑weiruanyahei.ttf。

TextView tv;

Typeface tf2 = Typeface.createFromAsset(getAssets(),"fonts/weiruanyahei.ttf");
tv.setTypeface(tf2);

方法二：建立基类，xml统一使用

package com.insight.androidfont;
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class FontTextView extends TextView {
private Context mContext;
private String TypefaceName = "";

public String getTypefaceName() {
return TypefaceName;
}

public void setTypefaceName(String typefaceName) {
TypefaceName = typefaceName;
Typeface typeface = Typeface.createFromAsset(mContext.getAssets(), "fonts/" + TypefaceName + ".ttf");
this.setTypeface(typeface);
System.gc();
}

public FontTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
this.mContext = context;
int resouceId = attrs.getAttributeResourceValue(null, "typefaceName", 0);
if (resouceId != 0) {
TypefaceName = context.getResources().getString(resouceId);
} else {
TypefaceName = attrs.getAttributeValue(null, "typefaceName");
}
if (TypefaceName != null && !"".equals(TypefaceName)) {
Typeface typeface = Typeface.createFromAsset(context.getAssets(), "fonts/" + TypefaceName + ".ttf");
this.setTypeface(typeface);
}
}

public FontTextView(Context context, AttributeSet attrs) {
super(context, attrs);
this.mContext = context;
// 先判断是否配置的资源文件
int resouceId = attrs.getAttributeResourceValue(null, "typefaceName", 0);
if (resouceId != 0) {
TypefaceName = context.getResources().getString(resouceId);
} else {
TypefaceName = attrs.getAttributeValue(null, "typefaceName");
}
if (TypefaceName != null && !"".equals(TypefaceName)) {
Typeface typeface = Typeface.createFromAsset(context.getAssets(), "fonts/" + TypefaceName + ".ttf");
this.setTypeface(typeface);
}
}

public FontTextView(Context context) {
super(context);
this.mContext = context;
// TypefaceName = attrs.getAttributeValue(null, "TypefaceName");
if (TypefaceName != null && !"".equals(TypefaceName)) {
Typeface typeface = Typeface.createFromAsset(context.getAssets(), "fonts/" + TypefaceName + ".ttf");
this.setTypeface(typeface);
}
}
}

下面是布局：

<com.insight.androidfont.FontTextView
android:id="@+id/fontTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="69dp"
typefaceName="weiruanyahei"
android:text="FontTextView"
android:textSize="30sp" />
大字体是要设置的属性，weiruanyahei是字体库的名字
