Android App Font Awesome

Question

我正在用fontawesome創建一個示例項目，我似乎無法解決錯誤。我正在關注這個tutorial。該錯誤告訴我，我無法使用管理器中的視圖。 錯誤是：

'markAsIconContainer(android.view.View, android.graphics.Typeface)' in 'com.example.fadil.fontawesome.FontManager' cannot be applied to '(android.view.View)' 

這裏是代碼：

MainActivity：

import android.graphics.Typeface; 
import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 

public class MainActivity extends AppCompatActivity { 

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

     Typeface iconFont = FontManager.getTypeface(getApplicationContext(), FontManager.FONTAWESOME); 
     FontManager.markAsIconContainer(findViewById(R.id.icons_container), iconFont); 
    } 
} 

FontManager：

import android.content.Context; 
import android.graphics.Typeface; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.TextView; 

public class FontManager { 

    public static final String ROOT = "fonts/", 
      FONTAWESOME = ROOT + "fontawesome-webfont.ttf"; 

    public static Typeface getTypeface(Context context, String font) { 
     return Typeface.createFromAsset(context.getAssets(), font); 
    } 

    public static void markAsIconContainer(View v, Typeface typeface) { 
     if (v instanceof ViewGroup) { 
      ViewGroup vg = (ViewGroup) v; 
      for (int i = 0; i < vg.getChildCount(); i++) { 
       View child = vg.getChildAt(i); 
       markAsIconContainer(child); 
      } 
     } else if (v instanceof TextView) { 
      ((TextView) v).setTypeface(typeface); 
     } 
    } 

} 

activity_main佈局：

需要幫助:)

Answer 1

得到的答案...

我不得不改變TTF文件位置的主目錄，而不是SRC ，併爲markAsIconContainer添加字體到括號中。

這裏是固定的代碼：

public static void markAsIconContainer(View v, Typeface typeface) { 
     if (v instanceof ViewGroup) { 
      ViewGroup vg = (ViewGroup) v; 
      for (int i = 0; i < vg.getChildCount(); i++) { 
       View child = vg.getChildAt(i); 
       markAsIconContainer(child, typeface); 
      } 
     } else if (v instanceof TextView) { 
      ((TextView) v).setTypeface(typeface); 
     } 
    } 

}
