问题描述
我想在我的Android应用程序中使用自定义字体。我遵循说明,并在Android studio中创建了一个资源
文件夹,其中我放置了 verdana.ttf
,如图所示: 然后我在我的 MainActivity
活动中调用以下内容:
code> public class MainActivity extends ActionBarActivity {
Typeface mainFont = Typeface.createFromAsset(getAssets(),verdana.ttf);
代码编译,但是当活动启动时,我得到一个 NullPointerException
上面的一行。我怀疑 verdana.ttf
文件可能已损坏,但尝试不同的字体时,错误仍然存在。清理项目也没有帮助。资产文件夹是否位于错误的位置?我可能会做错什么?
您正在尝试调用 createFromAsset()
从初始化程序。请在 super.onCreate()
调用后将其移动到 onCreate()
。在活动
中继承的方法在此之前可能无效。
I would like to use a custom typeface in my Android app. I followed instructions and created an assets
folder in Android studio in which I put verdana.ttf
, as shown on the picture:
Then I call the following in my MainActivity
activity:
public class MainActivity extends ActionBarActivity {
Typeface mainFont = Typeface.createFromAsset(getAssets(), "verdana.ttf");
The code compiles, but when the activity is launched, I get a NullPointerException
on the above line. I suspected the verdana.ttf
file might be corrupted, but the error persists when trying different typefaces. Cleaning the project does not help either. Is the assets folder in the wrong location? What might I be doing wrong?
You are trying to call createFromAsset()
from an initializer. Please move this to onCreate()
, after the super.onCreate()
call. Methods you inherit in your Activity
may not work before that point.
