Question

我跟随下面的链接中给出的教程：

http://www.androidhive.info/2013/07/android-expandable-list-view-tutorial/

我怎么可以给自定义字体（字体）在list_group.xml和list_item.xml textviews。

我已将Arial.ttf文件复制到资产文件夹中。

请帮帮我。

您可以创建自定义的TextView因为我已经在你的XML重写TextView的类，然后，而不是使用的TextView在这里完成你使用CustomTextView：

public class CustomTextView extends TextView { 

public CustomTextView(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
    init(context, attrs); 
} 

public CustomTextView(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    init(context, attrs); 
} 

public CustomTextView(Context context) { 
    super(context); 
} 

private void init(Context context, AttributeSet attrs) { 

} 

@Override 
public void setTypeface(Typeface tf, int style) { 
    if (!isInEditMode()) { 
    Typeface normalTypeFace = Typeface.createFromAsset(getContext() 
      .getAssets(), "Esans.ttf"); 
    Typeface boldTypeFace = Typeface.createFromAsset(getContext() 
      .getAssets(), "EsansBol.ttf"); 
    Typeface lightTypeFace = Typeface.createFromAsset(getContext() 
      .getAssets(), "EsansLig.ttf"); 
    Typeface mediumTypeFace = Typeface.createFromAsset(getContext() 
      .getAssets(), "EsansMed.ttf"); 
    //Modifying styles to support the different styles of custom font 
     switch (style) { 
     case Typeface.NORMAL: 
      super.setTypeface(normalTypeFace); 
      break; 
     case Typeface.BOLD: 
      super.setTypeface(boldTypeFace); 
      break; 
     case Typeface.ITALIC: 
      super.setTypeface(lightTypeFace); 
      break; 
     case Typeface.BOLD_ITALIC: 
      super.setTypeface(mediumTypeFace); 
      break; 
     default: 
      super.setTypeface(normalTypeFace); 
      break; 

     } 
    } 
} 

}

你可以试试这在XML添加字体在XML

public class TextViewPlus extends TextView { 
private static final String TAG = "TextView"; 

public TextViewPlus(Context context) { 
    super(context); 
} 

public TextViewPlus(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    setCustomFont(context, attrs); 
} 

public TextViewPlus(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
    setCustomFont(context, attrs); 
} 

private void setCustomFont(Context ctx, AttributeSet attrs) { 
    TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.TextViewPlus); 
    String customFont = a.getString(R.styleable.TextViewPlus_customFont); 
    setCustomFont(ctx, customFont); 
    a.recycle(); 
} 

public boolean setCustomFont(Context ctx, String asset) { 
    Typeface tf = null; 
    try { 
    tf = Typeface.createFromAsset(ctx.getAssets(), asset); 
    } catch (Exception e) { 
     Log.e(TAG, "Could not get typeface: "+e.getMessage()); 
     return false; 
    } 

    setTypeface(tf); 
    return true; 
} 

}

<com.icl.examples.TextViewPlus 
    android:id="@+id/textViewPlus1" 
    android:layout_height="match_parent" 
    android:layout_width="match_parent" 
    android:text="@string/info_text" 
    android:textColor="@color/White" 
    android:textStyle="bold" 
    android:textSize="50sp" 
    foo:customFont="Bamini.ttf"> 
</com.icl.examples.TextViewPlus> 

将它添加到资源，水库 - >价值观attrs.xml

<?xml version="1.0" encoding="utf-8"?> 
    <resources> 
     <declare-styleable name="TextViewPlus"> 
     <attr name="customFont" format="string"/> 
    </declare-styleable> 
    </resources>
