本文详细介绍了如何在Android平台上实现全屏显示的应用，涵盖了设置主题、修改布局、处理状态栏等多个关键步骤，旨在帮助开发者打造沉浸式用户体验。

全屏窗口

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

判断是否有SDCard

 if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
     { 
      copyToSDCard(logFilePath);
     }
     else {
      Toast.makeText(FPRITest.this,"No SDCard! Please insert SDCard. ",Toast.LENGTH_SHORT).show();
     }

格式化SD卡/卸载SD卡

private IMountService   mMountService;
mMountService = getMountService();

private synchronized IMountService getMountService() {
        if (mMountService == null) {
            IBinder service = ServiceManager.getService("mount");
            if (service != null) {
                mMountService = IMountService.Stub.asInterface(service);
            } else {
                Log.e(TAG, "Can't get mount service");
            }
        }
        return mMountService;
     }
//format sdcard
mMountService.formatMedia(Environment.getExternalStorageDirectory().toString());
//unmount sdcard
mMountService.unmountMedia(Environment.getExternalStorageDirectory().toString());

保持屏幕常亮

PowerManager.WakeLock wakeLock;

启用屏幕常亮功能

wakeLock = ((PowerManager)getSystemService(POWER_SERVICE)).
newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ON_AFTER_RELEASE, "MyActivity");
wakeLock.acquire();

//PowerManager.SCREEN_DIM_WAKE_LOCK 这个可维持在低明状态，还有其他的标志，可参考Andoid文档

关闭屏幕常亮功能

if (wakeLock != null) {
wakeLock.release();
}

需要权限

<uses-permission android:name="android.permission.WAKE_LOCK" />

为了不对其他程序造成影响，启用和关闭屏幕常亮的代码一般被放在 Activity 的 onResume() 和 onPause() 事件中。
