在配置檔案裡,如果設定android:targetSdkVersion=”18”，那麼必須android:configChanges=”orientation|keyboardHidden|screenSize”,activity中才會呼叫 onConfigurationChanged 監聽;如果去掉android:targetSdkVersion=”18”
android:configChanges=”orientation”也會監聽onConfigurationChanged變化

activity中程式碼如下

@Override
public void onConfigurationChanged
 
(Configuration newConfig) {
    // TODO Auto-generated method stub
    super.onConfigurationChanged(newConfig);
    if(this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){
            Log.d("test","----------橫屏------------");
    }else if(this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){
            Log.d("test"
 
,"----------豎屏------------");
        }
    }
