By default, when the screen aspect is switched, the onCreate () method of activity is called again, so you can read the orientation of the screen through the following code:
View plaincopy to clipboardprint?
Public void onCreate () {
If (this.getResources (). GetConfiguration ()
= = Configuration.ORIENTATION_LANDSCAPE) {
Log.i ("info", "landscape")
} else if (this.getResources () .getConfiguration ()
= = Configuration.ORIENTATION_PORTRAIT) {
Log.i ("info", "portrait")
}
}
Public void onCreate () {
If (this.getResources (). GetConfiguration ()
= = Configuration.ORIENTATION_LANDSCAPE) {
Log.i ("info", "landscape")
} else if (this.getResources () .getConfiguration ()
= = Configuration.ORIENTATION_PORTRAIT) {
Log.i ("info", "portrait")
}
}
If you add a configuration to androidmanifest.xml
Android:configChanges= "orientation | keyboardHidden | navigation
When the screen is flipped, Activity does not repeatedly call onCreate (), onPause (), and onResume ().
Instead, call onConfigurationChanged (Configuration newConfig)
