保存数据和改变方向 [英] Save data and change orientation

问题描述

我有两个活动，我使用android：configChanges =keyboardHidden |方向|屏幕尺寸

I have two activities and I use the android:configChanges="keyboardHidden|orientation|screenSize"

 @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) {

          }
      }

一个积极运用肖像的第二横向 但是当方向改变，活动加载和数据丢失

One active use for portrait to landscape orientation of the second but 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 和 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
