android - 在 Android 应用程序中更改字体会使应用程序崩溃 - 无法制作 native 字体

Question

我正在尝试在我的 android 应用程序中包含自定义字体。这是我遵循的教程，这似乎对很多人都有效:http://tharindudassanayake.wordpress.com/2012/02/25/use-sinhala-fonts-for-your-android-app/

我是这样尝试的:

XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/sinhala_font"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="wdhqfndajka"
        android:textSize="25sp" />

</LinearLayout>

代码:

TextView txt = (TextView) findViewById(R.id.sinhala_font);
        Typeface font = Typeface.createFromAsset(getAssets(), "fonts/amal.TTF");
        txt.setTypeface(font);

不幸的是，应用程序崩溃了(由于无法制作原生字体)，我在我的日志猫中得到以下信息:

这可能是什么原因？感谢您的帮助!

Answer 1

您是在 Assets 中创建了一个名为 fonts 的文件夹，还是直接放置在 assets 文件夹中？如果没有创建文件夹，请创建一个文件夹并将您的字体文件放在那里我认为是错误的..在你的例子中，他没有创建他直接访问的任何 fonts 文件夹，但你正在从 fonts 文件夹访问..

如果不是字体文件夹，则将此行更改为。

Typeface font = Typeface.createFromAsset(getAssets(), "fonts/amal.TTF");

像这样..

Typeface font = Typeface.createFromAsset(getAssets(), "amal.TTF");
