/** * 切换全屏,取消全屏 * * @param isChecked */ private void switchFullScreen(boolean isChecked) { if (isChecked) { //切换到全屏模式 //添加一个全屏的标记 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); //请求横屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); //设置视频播放控件的布局的高度是match_parent FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) mVideoRootView.getLayoutParams(); //将默认的高度缓存下来 mVideoHeight = layoutParams.height; layoutParams.height = FrameLayout.LayoutParams.MATCH_PARENT; mVideoRootView.setLayoutParams(layoutParams); } else { //切换到默认模式 //清除全屏标记 getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); //请求纵屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); //设置视频播放控件的布局的高度是200 FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) mVideoRootView.getLayoutParams(); layoutParams.height = mVideoHeight; //这里的单位是px mVideoRootView.setLayoutParams(layoutParams); } }

横竖屏切换时的生命周期总结：

1、不设置Activity的android:configChanges时，切屏会重新调用各个生命周期，切横屏时会执行一次，切竖屏时会执行两次

2、设置Activity的android:configChanges=”orientation”时，切屏还是会重新调用各个生命周期，切横、竖屏时只会执行一次

3、设置Activity的android:configChanges=”orientation|keyboardHidden”时，切屏不会重新调用各个生命周期，只会执行onConfigurationChanged方法

//添加一个全屏的标记 window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN) ScreenUtils.setAllFull(this) val rootView: ViewGroup = findViewById(android.R.id.content) as ViewGroup rootView.setPadding(0, 0, 0, 0) val layoutParams = mWebView?.layoutParams as RelativeLayout.LayoutParams //将默认的高度缓存下来 mWebViewHeight = layoutParams.height layoutParams.height = RelativeLayout.LayoutParams.MATCH_PARENT mWebView?.layoutParams = layoutParams val rootView: ViewGroup = findViewById(android.R.id.content) as ViewGroup val resourceId = resources.getIdentifier("status_bar_height", "dimen", "android") val statusBarHeight = resources.getDimensionPixelSize(resourceId) rootView.setPadding(0, statusBarHeight, 0, 0) window.addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN) window.addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
