私のアプリケーションは正常に動作しますが、バックグラウンドになり、再開後に logcat で次のエラーが発生して動作が停止します。

誰かがすでにAndroidのドキュメントを見て呼び出したときにトリガーfinish()されるonDestroy()ので、呼び出すべきではありません。イベントの呼び出しと同じことです。達成しようとしているのがFragmentDisplayをActivityStatePagerから切り離すことである場合は、移動する必要があります。onDestroy()finish()finish()onPause()

if (savedInstanceState == null) {
        FragmentDisplay fragment = new FragmentDisplay();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content, fragment).commit();
    }

イベントに入れ、onResume()イベントでこのフラグメントを切り離しonPause()ます。コードを使用すると、アクティビティが一時停止されるたびにonCreate（）の呼び出しが強制されますが、これは手間のかかる操作です。

java.lang.IllegalArgumentException: No view found for id 0x7f060038例外はあなたの活動のやり方から来ていると思いますonResume()。

また、あなたは何をするのかを示すことができますRecordList.RecordListFragment.BackgroundTaskか？そこNullPointerExceptionから始まります。

RecordList.RecordListFragment.BackgroundTaskコードが追加された後に編集します。

わかりました、私はこれを手に入れたと思います。doInBackground（）で実行している間は、UIThreadにアクセスしないでください。バックグラウンドスレッドで行う作業がまだある間に、UIを変更するにはAsyncTask.publishProgress()、オーバーライドを使用します（ AsynTaskのドキュメントを参照してください）。あなたの場合のシナリオでは、AsyncTask.onProgressUpdate()

                        View composer = v.findViewById(R.id.lsComposer);
                        mLsComposer = ((DynamicListView) composer);
                        try {
                            mLsComposer
                                    .setAdapter(mAdapter = new PaginationComposerAdapter(
                                            mSP, getActivity(),
                                            rarray, name,
                                            label, mEventStatus));
                            Options(men);
                        } catch (Exception e) {
                            Log.d("exception", "this is here at composer"+e);
                            e.printStackTrace();
                        }
                        if (mAdapter.getCount() > 10) {
                            mLsComposer
                                    .setLoadingView(getActivity()
                                            .getLayoutInflater()
                                            .inflate(
                                                    R.layout.lscomposer_loadingview,
                                                    null));
                        }
                        Log.d("complete","at the end");

onPostExecute()長い作業が終わった後にUIに変更を加えたいからです。
