android中怎么相应横屏竖屏事件？？？？？？？？

   @Override
public void onConfigurationChanged(Configuration newConfig) {
// TODO Auto-generated method stub
super.onConfigurationChanged(newConfig);


 if(newConfig.orientation==ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
 {

 Toast.makeText(this,"现在是竖屏", Toast.LENGTH_SHORT).show();  container.removeAllViews();
             container.addView(getLocalActivityManager().startActivity(
                     "Module2",
                     new Intent(zhujiem.this, BeateryActivity.class)
                             .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
                     .getDecorView());
 }
 else if(newConfig.orientation==ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)
 {

 container.removeAllViews();
        container.addView(getLocalActivityManager().startActivity(
                "Module1",
                new Intent(zhujiem.this, hengping.class)
                        .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
                .getDecorView());
 Toast.makeText(this,"现在是横屏", Toast.LENGTH_SHORT).show();  } }AndroidManifest.xml中的配置
<activity android:name=".zhujiem"
         android:configChanges="keyboardHidden|orientation"
          android:label="@string/app_name">
            <intent-filter></activity>请教这样写应该没错把，但是怎么就不响应横屏事件？为啥？
