代码设置全屏和退出全屏

// 显示全屏
private void setFullScreen() {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}


//退出全屏
private void quitFullScreen() {//279.13
final WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setAttributes(attrs);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

}

在任何你想设置的地方调用该方法即可实现效果。
