Android 判断当前屏幕是横屏还是竖屏
//获取设置的配置信息
Configuration mConfiguration = this.getResources().getConfiguration(); //获取屏幕方向int ori = mConfiguration.orientation; if (ori == mConfiguration.ORIENTATION_LANDSCAPE) { //当前为横屏 //强制为竖屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);} else if (ori == mConfiguration.ORIENTATION_PORTRAIT) { //当前为竖屏 //强制为横屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);}这个时候回调用onConfigurationChanged 这个方法
需要添加或者清除Flage
@Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) { //横屏 //强制为竖屏 getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); } else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) { //竖屏 // 强制为横屏 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); } }最后看一下点击横屏的点击事件
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) { //横屏 //强制为竖屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, (int) dp2px(210)); txVideoview.setLayoutParams(lp); } else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) { //竖屏 //强制为横屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); txVideoview.setLayoutParams(lp); }最后需要在Activity中加上属性
android:configChanges="orientation|screenSize"防止手机旋转时, Activity被重建.
