Question

在BaseGameActivity.java我有方法可以轻松创建字体。但不幸的是，当创建字体时，应用程序停止了。该代码不包含语法错误。

BaseGameActivity.java

public class BaseGameActivity extends Activity {

    private Map<String,Typeface> typefaces = new HashMap<String,Typeface>();

    protected void addTypeface(String name) {
        Typeface typeface = Typeface.createFromAsset(getAssets(), name+".tff");
        typefaces.put(name, typeface);
    }

    protected void setTypeface(TextView v, String typefaceName) {
        Typeface t = typefaces.get(typefaceName);
        if(t != null) {
            v.setTypeface(t);
        }
    }
}

MainAcitivity.java

public class MainActivity extends BaseGameActivity {

    private static final String FONTNAME = "airmole";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        addTypeface(FONTNAME);
        setTypeface((TextView) findViewById(R.id.title), FONTNAME);
    }
}

文件airmole.tff位于assets文件夹中。

logcat的

通常你应该这样做：

Typeface typeface = Typeface.createFromAsset(getContext().getAssets(), name+".tff");

字体导致＆＃34;不幸（应用程序名称）已停止＆＃34;
