如何在通知中應用字體

Question

我正在開發Android應用程序，但我無法爲應用程序Notification標題設置自定義字體。

我不想使用任何自定義佈局Notification。我想在默認Notification標題中應用字體。

我不知道應該可能與否。 在此先感謝。

Answer 1

創建文本位圖圖像，並設置遠程視窗

長衝浪後，我已經弄清楚我的問題如下：

我已創建自定義佈局view_notification.xml如下：

view_notification.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_gravity="center_vertical" 
android:background="@color/white" 
android:gravity="center_vertical" 
android:orientation="horizontal"> 
<ImageView 
    android:id="@+id/ivNotificationImage" 
    android:layout_width="40dp" 
    android:layout_height="40dp" 
    android:src="@drawable/iconlarge" 
    android:layout_gravity="center_vertical" 
    android:layout_margin="5dp"/> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_vertical" 
    android:layout_marginLeft="10dp" 
    android:orientation="vertical"> 

    <TextView 
     android:id="@+id/tvNotificationTitle" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginTop="5dp" 
     android:text="@string/app_name" 
     android:textStyle="bold" 
     android:textColor="@color/black" 
     android:textSize="16sp" 
     android:maxLines="1"/> 

    <TextView 

     android:id="@+id/tvMessage" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:textSize="14sp" 
     android:textColor="@color/black" 
     android:maxLines="1"/> 

</LinearLayout> 

我已經創建CustomTypefaceSpan.java爲TypeFace如下：

CustomTypefaceSpan.java

public class CustomTypefaceSpan extends TypefaceSpan { 

private final Typeface newType; 

public CustomTypefaceSpan(String family, Typeface type) { 
    super(family); 
    newType = type; 
} 

@Override 
public void updateDrawState(TextPaint ds) { 
    applyCustomTypeFace(ds, newType); 
} 

@Override 
public void updateMeasureState(TextPaint paint) { 
    applyCustomTypeFace(paint, newType); 
} 

private static void applyCustomTypeFace(Paint paint, Typeface tf) { 
    int oldStyle; 
    Typeface old = paint.getTypeface(); 
    if (old == null) { 
     oldStyle = 0; 
    } else { 
     oldStyle = old.getStyle(); 
    } 

    int fake = oldStyle & ~tf.getStyle(); 
    if ((fake & Typeface.BOLD) != 0) { 
     paint.setFakeBoldText(true); 
    } 

    if ((fake & Typeface.ITALIC) != 0) { 
     paint.setTextSkewX(-0.25f); 
    } 

    paint.setTypeface(tf); 
} 
} 

我已經轉換我的簡單文本代碼以SpannableStringBuilder如下：

SpannableStringBuilder sb = new SpannableStringBuilder(object.getString("description") + ""); 
      Typeface font = Typeface.createFromAsset(getAssets(), "shruti.ttf"); 
      sb.setSpan(new CustomTypefaceSpan("", font), 0, sb.length() - 1, 
        Spanned.SPAN_EXCLUSIVE_INCLUSIVE); 

sendNotification(title, sb); 

我已經使用RemoteViews自定義佈局裏面有Notification查看。

public void sendNotification(String title, SpannableStringBuilder sb) { 

    RemoteViews remoteViews = new RemoteViews(getPackageName(), 
      R.layout.view_notification); 

    NotificationCompat.Builder mBuilder = 
      new NotificationCompat.Builder(this) 
        .setSmallIcon(R.drawable.iconlarge) 
        .setAutoCancel(true) 
        .setContent(remoteViews); 

    remoteViews.setTextViewText(R.id.tvNotificationTitle, getResources().getString(R.string.app_name)); 
    remoteViews.setTextViewText(R.id.tvMessage, sb); 
... 
... 
}
