短视频app开发，视频、直播画面跟随手机横屏、竖屏移动实现的相关代码

隐藏标题栏

基于xml

1	<application<br>    android:theme="@style/Theme.AppCompat.Light.NoActionBar"><br>动态隐藏<br>//继承自Activity时使用<br>requestWindowFeature(Window.FEATURE_NO_TITLE);<br> <br>//继承自AppCompatActivity时使用<br>getSupportActionBar().hide();

​设置为全屏

1	xml<br>android:theme="@android:style/Theme.NoTitleBar.Fullscreen" <br>或者 <br>android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"

动态设置

1	requestWindowFeature(Window.FEATURE_NO_TITLE);<br> <br>getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,<br>                WindowManager.LayoutParams.FLAG_FULLSCREEN);

横竖屏切换

屏幕旋转方式

1	AndroidManifest.xml<br>android:screenOrientation=""

动态设置

1	setRequestedOrientation(@ActivityInfo.ScreenOrientationint requestedOrientation);

动态设置屏幕方向

1

/**<br>* The preferred screen orientation this activity would like to run in.<br>* From the {@link android.R.attr#screenOrientation} attribute, one of<br>* {@link #SCREEN_ORIENTATION_UNSPECIFIED},<br>* {@link #SCREEN_ORIENTATION_LANDSCAPE},<br>* {@link #SCREEN_ORIENTATION_PORTRAIT},<br>* {@link #SCREEN_ORIENTATION_USER},<br>* {@link #SCREEN_ORIENTATION_BEHIND},<br>* {@link #SCREEN_ORIENTATION_SENSOR},<br>* {@link #SCREEN_ORIENTATION_NOSENSOR},<br>* {@link #SCREEN_ORIENTATION_SENSOR_LANDSCAPE},<br>* {@link #SCREEN_ORIENTATION_SENSOR_PORTRAIT},<br>* {@link #SCREEN_ORIENTATION_REVERSE_LANDSCAPE},<br>* {@link #SCREEN_ORIENTATION_REVERSE_PORTRAIT},<br>* {@link #SCREEN_ORIENTATION_FULL_SENSOR},<br>* {@link #SCREEN_ORIENTATION_USER_LANDSCAPE},<br>* {@link #SCREEN_ORIENTATION_USER_PORTRAIT},<br>* {@link #SCREEN_ORIENTATION_FULL_USER},<br>* {@link #SCREEN_ORIENTATION_LOCKED},<br>*/

设置横竖屏切换

不想Activity被销毁重建需要静态设置

android:configChanges="orientation|keyboardHidden|screenSize"<br>Andorid 3.2以前的SDK可以使用如下配置<br>android:configChanges="orientation|keyboardHidden"<br>Adnroid 3.2以后的SDK必须添加一个screenSize属性，具体如下<br>android:configChanges="keyboardHidden|orientation|screenSize"<br>或者<br>android:configChanges="orientation|screenSize"
