Android 应用程序在 Typeface.createFromAsset 上崩溃

Question

我的应用程序因以下代码而崩溃。我正在尝试在 textView 中提供自定义字体。 Assets 目录没问题，因为我已经仔细检查过了。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TextView title = (TextView) findViewById(R.id.textView);
    String BANGLA_FONT_SOLEMAN_LIPI = "/SolaimanLipi_Bold_10-03-12.ttf";
    Typeface tf = Typeface.createFromAsset(getApplicationContext().getAssets(),
            BANGLA_FONT_SOLEMAN_LIPI);
    title.setTypeface(tf);
}

当应用程序崩溃时，它会产生以下错误日志:

Answer 1

基本上有 4 种情况会导致这种情况:

1.你用错了扩展名

2.你把字体放在assets文件夹里而不是assets/fonts/

3.你把字体拼错了

4.字体需要小写(在我的例子中，解决方案是将 MyFont.ttf 重命名为 myfont.ttf，奇怪)
