无法更改的TextView风格的OnCreate

Question

我无法通过功能initFonts()在我班上的onCreate()功能，更改文本样式。没有错误，但没有任何反应。我正在运行一个无限循环（延迟1秒）的runnable。这是一个问题吗？

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_main); 

     initFonts(); 

     // Start a load dialog 
     progressdialog = new ProgressDialog(MainActivity.this); 
     progressdialog.setTitle("Please wait"); 
     progressdialog.setMessage("Loading..."); 
     progressdialog.setCancelable(false); 
     progressdialog.show(); 


     // Start updating all lists 
     runnable = new Runnable() { 
      public void run() { 
       updateList(); 
      } 
     }; 

     // Keep it running 
     runnable.run();   
    } 

，我改变了字体的initFonts()方法：

TextView cur = (TextView)findViewById(R.id.current); 
TextView plus = (TextView)findViewById(R.id.plus); 
TextView min = (TextView)findViewById(R.id.min); 

cur.setTextSize(150); 
Typeface font = Typeface.createFromAsset(getAssets(), "font.ttf"); 
cur.setTypeface(font); 

plus.getBackground().setAlpha(45); 
min.getBackground().setAlpha(45); 

Answer 1

Typeface font = Typeface.createFromAsset(getAssets(), "foldername/font.ttf"); 
cur.setTypeface(font);
