加載probem - 小部件中的自定義字體

我在小部件中的自定義字體有問題。我嘗試了這個方法question。我把資源/字體中的字體文件（Moon.ttf）。在值/ attrs中添加一個xml。當我將小部件添加到主屏幕時，它會顯示加載問題。在logcat中顯示這些。我不明白爲什麼它不起作用。加載probem - 小部件中的自定義字體

這裏是FontableTextView類：

public class FontableTextView extends TextView { 
    public static final String TAG = "TextView"; 
    public FontableTextView(Context context) { 
     super(context); 
    } 

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

    } 

    public FontableTextView(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.FontableTextView); 
     String customFont = a.getString(R.styleable.FontableTextView_font); 
     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 false; 
    } 
}

attrs.xml

<resources> 
     <declare-styleable name="FontableTextView"> 
     <attr name="font" format="string"/> 
    </declare-styleable> 
</resources>

和Widget佈局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:foo="http://schemas.android.com/apk/res/com.pxr.tutorials.widget.basic" 
    android:id="@+id/LinearLayout01" 
    android:layout_height="200dp" 
    android:layout_width="320dp" 
     > 

<ImageView 
    android:id="@+id/imageView1" 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent" 
    android:layout_centerInParent="true" 
    android:src="@drawable/quote1" /> 

    <LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:paddingLeft="20dp" 
    android:paddingRight="20dp" 


     > 

<TextView 
    android:paddingTop="20dp" 
    android:id="@+id/widget_textview" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:gravity="center_vertical|center_horizontal" 
    android:textColor="@android:color/black" 
    android:text="@string/quote" 
    android:textSize="7pt" 
    android:layout_weight="2" 
    android:textStyle="italic" 
    android:ellipsize="end" 

    /> 
<com.pxr.tutorials.widget.basic.FontableTextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:textSize="5pt" 
    android:text="@string/app_name" 
    android:textColor="@android:color/black" 
    foo:font="Moon.ttf" 
    ></com.pxr.tutorials.widget.basic.FontableTextView> 

<TextView 
    android:id="@+id/widget_textview_author" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:gravity="bottom|left" 
    android:textColor="@android:color/black" 
    android:text="@string/author" 
    android:textSize="5pt" 
    android:paddingLeft="0dp" 
    android:paddingBottom="25dp" 
    android:layout_weight="1" 

    /> 
</LinearLayout> 
    </RelativeLayout>

當它是一個主屏幕小部件之外使用請問您查看的工作？ – wsanville

hmm logcat顯示此「無法獲得字體：null」，但我不知道爲什麼？字體在正確的文件夾中; / – Dariusz

自定義佈局尚未支持主屏幕小部件。您需要使用Canvas和繪製文本，如果你想使用自定義的字體

你已經得到，因爲這低於行錯誤將其設置爲ImageView

xmlns:foo="http://schemas.android.com/apk/res/com.pxr.tutorials.widget.basic"

試試這個 xmlns:foo="http://schemas.android.com/apk/res-auto/com.pxr.tutorials.widget.basic" instead of

在這裏，我把我的代碼，例如

public class CustomTextView extends TextView { 

public CustomTextView(Context context) { 
    super(context); 
    Typeface face = Typeface.createFromAsset(context.getAssets(), 
      "LFAX.TTF"); 
    this.setTypeface(face); 
} 

public CustomTextView(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    Typeface face = Typeface.createFromAsset(context.getAssets(), 
      "LFAX.TTF"); 
    this.setTypeface(face); 
} 

public CustomTextView(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
    Typeface face = Typeface.createFromAsset(context.getAssets(), 
      "LFAX.TTF"); 
    this.setTypeface(face); 
} 

@Override 
protected void onDraw(Canvas canvas) { 

    super.onDraw(canvas); 
}

}

我的XML是

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
xmlns:custom="http://schemas.android.com/apk/res-auto/com.ninespl.medoracab.utils" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:background="@color/bg_color" 
tools:ignore="UnknownIdInLayout,HardcodedText,DuplicateIds" > 


<com.ninespl.medoracab.utils.CustomTextView 
    android:id="@+id/car_listing_header" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true" 
    > 
</com.ninespl.medoracab.utils.CustomTextView>
