请参阅此http://stackoverflow.com/a/16883281/4494555 – Jas

误差在初始化你的字体。您是否直接在资产文件夹或类似资产/字体中存储您的ttf –

字体直接位于资产文件夹内。我没有在资产内创建子文件夹 – jobin

尝试我 -

package com.example.customviews; 
    import android.content.Context; 
    import android.util.AttributeSet; 
    import android.widget.TextView; 

public class CustomTextView extends TextView { 

public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) { 
    super(context, attrs, defStyleAttr); 
    setTypeface(Utils.getTypeFace(context)); 
} 

public CustomTextView(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    setTypeface(Utils.getTypeFace(context)); 
} 

public CustomTextView(Context context) { 
    super(context); 
    setTypeface(Utils.getTypeFace(context)); 
}

这一点，工作}

public class Utils { 
public static Typeface getTypeFace(Context context) { 
    return Typeface.createFromAsset(context.getAssets(),"Arail.ttf"); 
}

而在侑XML的

 <com.example.customviews.CustomTextView 
      android:id="@+id/textView" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" />

我试过了您给我的代码。取而代之Arial.ttf我使用A771- Roman-Regular.ttf，但我得到以下渲染问题 – jobin

你可以做这样的事情..

<resources> 
<style name="MyFont" parent="@android:style/TextAppearance.Medium"> 
    <item name="android:layout_width">wrap_content</item> 
    <item name="android:layout_height">wrap_content</item> 
    <item name="android:textColor">your_color</item> 
    <item name="android:typeface">name of your_custom font</item> 
</style>

它的工作对我来说

Textiew textView = (TextView) toolbar.findViewById(R.id.toolbar_title); 
Typeface typeFace =Typeface.createFromAsset(getAssets(),Constants.TYPEFACE_SOLAIMAN_LIPI); 

    textView.setTypeface(typeFace); 
    textView.setText(getString(R.string.welcome)); 
    setSupportActionBar(toolbar);

是与反思。这工作：

import java.lang.reflect.Field; 
import android.content.Context; 
import android.graphics.Typeface; 

public final class FontsOverride { 

public static void setDefaultFont(Context context, 
     String staticTypefaceFieldName, String fontAssetName) { 
    final Typeface regular = Typeface.createFromAsset(context.getAssets(), 
      fontAssetName); 
    replaceFont(staticTypefaceFieldName, regular); 
} 

protected static void replaceFont(String staticTypefaceFieldName, 
     final Typeface newTypeface) { 
    try { 
     final Field staticField = Typeface.class 
       .getDeclaredField(staticTypefaceFieldName); 
     staticField.setAccessible(true); 
     staticField.set(null, newTypeface); 
    } catch (NoSuchFieldException e) { 
     e.printStackTrace(); 
    } catch (IllegalAccessException e) { 
     e.printStackTrace(); 
    } 
} 
}

然后，您需要重载几个默认字体，例如在应用程序类：

public final class Application extends android.app.Application { 
    @Override 
    public void onCreate() { 
     super.onCreate(); 
     FontsOverride.setDefaultFont(this, "DEFAULT", "MyFontAsset.ttf"); 
     FontsOverride.setDefaultFont(this, "MONOSPACE", "MyFontAsset2.ttf"); 
     FontsOverride.setDefaultFont(this, "SERIF", "MyFontAsset3.ttf"); 
     FontsOverride.setDefaultFont(this, "SANS_SERIF", "MyFontAsset4.ttf"); 
    } 
}

或者当然，如果你使用的是相同的字体文件，则可以改善这加载一次。

不过，我倾向于只覆盖一个，说 “MONOSPACE”，然后设置一个样式，迫使该字体的字体应用广泛：

<resources> 
<style name="AppBaseTheme" parent="android:Theme.Light"> 
</style> 

<!-- Application theme. --> 
<style name="AppTheme" parent="AppBaseTheme"> 
    <item name="android:typeface">monospace</item> 
</style>

API 21的是Android 5.0 我已经调查在评论中的报告，它不工作，它似乎与主题android：Theme.Material.Light不兼容。

如果这个主题是不是对你很重要，使用较旧的主题，例如：

<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar"> 
    <item name="android:typeface">monospace</item> 
</style>
