安卓自学，手机上的横竖屏切换，状态栏隐藏

手机切换横竖屏崩溃在mainfest.xml对应的ACTIVITY中添加这段android:configChanges="orientation|screenSize" 就不会崩溃啦

动态设置横竖屏方法 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE一面横屏

ActivityInfo.SCREEN_ORIENTATION_PORTRAIT一面竖屏

ActivityInfo.SCREEN_ORIENTATION_NOSENSOR 不受影响默认竖屏

ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE 两面横屏转换

ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT 两面竖屏转换

ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR 根据重力变换四面

XML中设置横竖屏

android:screenOrientation="landscape"

// 隐藏标题栏getWindow().requestFeature(Window.FEATURE_NO_TITLE);// 隐藏手机状态栏getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

隐藏手机虚拟导航栏

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus && Build.VERSION.SDK_INT >= 19) {
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
