您需要递归遍历视图树。当前，您仅列出根视图的子级。
换句话说，您需要这样的东西：
@Overridepublic void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ... Typeface font = Typeface.createFromAsset(getAssets(), "fonts/choco.ttf"); ViewGroup rootView = (ViewGroup) findViewById(android.R.id.content).getRootView(); applyFontRecursively(rootView, font);}void applyFontRecursively(ViewGroup parent, Typeface font) { for(int i = 0; i < parent.getChildCount(); i++) { View child = parent.getChildAt(i); if(child instanceof ViewGroup) { applyFontRecursively((ViewGroup)child, font); } else if(child != null) { Log.d("menfis", child.toString()); if(child.getClass() == TextView.class) { ((TextView) child).setTypeface(font); } } }}
