在android上添加自定义字体时崩溃

Question

我已关注此SO（例外答案）并将FontAwesome.otf 添加到assets/fonts 文件夹 这是我的字符串：

<!-- icons -->
    <string name="list_icon">&#xf03a;</string>
    <string name="plus_icon">&#xf067;</string>
    <string name="search_icon">&#xf002;</string>

这里是按钮：

<Button
            android:id="@+id/b1"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="@drawable/navigation_button"
            style="?android:attr/buttonBarButtonStyle" 
            android:textColor="#FFFFFF"
            android:text="@string/search_icon" />

        <Button
            android:id="@+id/b2"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="@drawable/navigation_button"
            style="?android:attr/buttonBarButtonStyle"
            android:textColor="#FFFFFF"
            android:text="@string/plus_icon" />

        <Button
            android:id="@+id/b3"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="@drawable/navigation_button"
            style="?android:attr/buttonBarButtonStyle"
            android:textColor="#FFFFFF" 
            android:text="@string/list_icon" />

这里是字体：

font = Typeface.createFromAsset(getAssets(), "/fonts/FontAwesome.otf" );

这里又是按钮：

        B1 = (Button) findViewById(R.id.b1);
        B2 = (Button) findViewById(R.id.b2);
        B3 = (Button) findViewById(R.id.b3);

        B1.setTypeface(font);
        B2.setTypeface(font);
        B3.setTypeface(font);

这里是日志：

这有什么问题？？

查看您引用的链接后，我发现与下面的代码行不同。似乎引用的链接只是使用文件名作为参数，而您正在提供文件的路径。也可能你想将字体声明为字体，除非在代码的前面已经这样做了。

您的代码...

font = Typeface.createFromAsset(getAssets(), "/fonts/FontAwesome.otf" );

来自引用链接的代码...

Typeface font = Typeface.createFromAsset( getAssets(), "fontawesome-webfont.ttf" );
