android - android - how to finish an activity when the orientation is changed?

Question

What I'm trying to do is to close the Activity if the user is changing the orientation in the middle of the use.

I have added to this activity the following line in the manifest -

android:configChanges="orientation"

and I have also overridden onConfigurationChanged:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    finish();
}

But it seems that it doesn't do the trick, so what am I doing wrong here?

Answer 1

还要添加keyboardHidden 和screenSize。

android:configChanges="orientation|keyboardHidden|screenSize"

注意：screenSize 仅适用于您的应用程序针对 API 级别 13 或更高级别。

Answer 2

int a=3;

public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);

// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
    if(a==3 || a==0)
    { 
      a=0;
    }else
{ finish(); }
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
    if(a==3 || a==1)
    { 
      a=0;
    }else
{ finish(); }
}
}
