样式与主题
一、样式的定义、继承、及引用
1、定义及继承的格式：
@Overrideprotected void onCreate(Bundle savedInstanceState) {setTheme(android.R.style.Theme_Black_NoTitleBar_Fullscreen);super.onCreate(savedInstanceState);setContentView(R.layout.main);}即在super.onCreate(savedInstanceState);之前加上这么一句话setTheme(android.R.style.Theme_Black_NoTitleBar_Fullscreen);
