Android 应用的全屏和非全屏实现代码

  /**   * 全屏显示   */  private void setFullSreen() {    WindowManager.LayoutParams params = getWindow().getAttributes();    params.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;    getWindow().setAttributes(params);    getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);    //getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN); // Activity全屏显示，且状态栏被覆盖掉  }

 /**   * 退出全屏   */  private void exitFullSreen() {    WindowManager.LayoutParams params = getWindow().getAttributes();    params.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);    getWindow().setAttributes(params);    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);    //getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN); // Activity全屏显示，但是状态栏不会被覆盖掉，而是正常显示，只是Activity顶端布局会被覆盖住  }
