我建立了我自己的字典應用程序。但我嘗試在我的應用中使用自定義字體。然後它不能顯示單詞的定義。請幫助我在哪裏我是假的。我不知道如何使用自定義字體。我在哪裏假？

你這是怎麼設置自定義字體，如果你在你的資產文件夾中的文件名爲.ttf。

//Set font style 
    Typeface tf; 
    // Font path 
    //public static String fontPath = "fonts/TELE2.TTF"; 
    public static String fontPath = "fonts/SketchRockwell-Bold.ttf"; 
    TextView tv_title; 

//中的onCreate（）：

tv_title = (TextView)findViewById(R.id.login_tv_title); 
     //Set font style 
     tf = Typeface.createFromAsset(getAssets(), fontPath); 
     tv_title.setTypeface(tf);
