Android中隐藏顶部状态栏:

方法一:
 //去除title
requestWindowFeature(Window.FEATURE_NO_TITLE);

//去掉Activity上面的状态栏 (注意这句话放的位置应定要放在setContentView之前)
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

setContentView(R.layout.video_view);
initView();
 }

方法二：
            android:name="*.Activity"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
