Question

我在widget中有自定义字体的问题。我试过这个question的方法。我把字体文件（Moon.ttf）放在资产/字体中。在values / attrs中添加一个xml。当我将我的小部件添加到主屏幕时，它显示加载问题。在logcat中显示这些。我不知道为什么它不起作用。

这是FontableTextView类：

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>

小部件布局：

<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

Answer 1

主屏幕小部件尚不支持自定义布局。如果要使用自定义字体，则需要使用Canvas并绘制文本并将其设置为ImageView

Answer 2

由于下面这行

，你有错误

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

试试这个 xmlns:foo="http://schemas.android.com/apk/res-auto/com.pxr.tutorials.widget.basic" instead of

这里我将我的代码放在

中

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>
