 @Override
      public void onConfigurationChanged(Configuration newConfig) {
          super.onConfigurationChanged(newConfig);
        setContentView(R.layout.activity_main);
          if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {

          } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {

One active use for portrait to landscape orientation of the secondbut when the orientation changes, activity is loaded and data is lost

我怎么能保存数据并更改活动的方向?

推荐答案

如果您有较少的数据,你可以保存和使用得到它 onSavedInstanceState onRestoreInstanceState ..对deatils通过这个链接保存数据

If you have a less data you can save and get it using onSavedInstanceState and onRestoreInstanceState .. for deatils go through this link Saving data

但柜面你有大量的数据,那么我必须说,你不应该允许方向变化,你可以通过添加下面的清单文件行限制的:

But incase you have large data then I must say you should not allow for the orientation changes you can restrict it by adding below line in manifest file :

android:configChanges="orientation|keyboardHidden" // fixes orientation
