嗨,我在使用带有片段的 AppCompatActivity 时遇到问题

我已经使用 AppCompatActivity 扩展了一个处理片段的类,当用户发送应用程序背景并等待几分钟然后将应用程序置于前面时,就会出现问题。除了这种情况,它根本不会崩溃。(还有一些不必要的代码还在开发中,所以不要关注它们)

任何帮助将不胜感激,我已经坚持了好几天。

如果还有其他需要,我可以更新问题并添加它们

public class SurveyMainFragment extends AppCompatActivity{

    private Toolbar toolbar;
    private Fragment surveyListFragment;
    private Logger Log;


    private SurveyResponseObj surveyResponseObj;


    @Bind(R.id.RelativeSurveyMainFragmentSurveys)
    RelativeLayout surveyTab;

    @Bind(R.id.RelativeSurveyMainFragmentProfile)
    RelativeLayout profileTab;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.survey_main_fragment);

        Log = Logger.getLogger(SurveyMainFragment.class);
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        toolbar.setVisibility(View.GONE);

        ButterKnife.bind(this);


        surveyTab.setSelected(true);
        profileTab.setSelected(false);


        Intent i = getIntent();
        if (i != null) {
            surveyResponseObj = i.getParcelableExtra("SurveyResponseList");
        }

        if (surveyResponseObj != null) {

        }


        surveyListFragment = new SurveyListFragment();

        displayFirstTimeUserFragment();

    }

    @OnClick(R.id.RelativeSurveyMainFragmentSurveys)
    void surveysFragment() {
        surveyTab.setSelected(true);
        profileTab.setSelected(false);
    }

    @OnClick(R.id.RelativeSurveyMainFragmentProfile)
    void profileFragment() {
        surveyTab.setSelected(false);
        profileTab.setSelected(true);
    }

    protected void displayFirstTimeUserFragment() {
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        if (surveyListFragment.isAdded()) { // if the fragment is already in container
            ft.show(surveyListFragment);
        } else { // fragment needs to be added to frame container
            Bundle bundle = new Bundle();
            bundle.putParcelable("surveyResponse", surveyResponseObj);
            surveyListFragment.setArguments(bundle);
            ft.add(R.id.fragment_survey_place, surveyListFragment, "SurveyListFragment");
        }

        ft.commit();
    }


    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        Log.i("onSaved"+outState.toString());
//        outState.putInt("someVarA", someVarA);
//        outState.putString("someVarB", someVarB);
    }

    @Override
    public void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        Log.i("onRestoreInstanceState" + savedInstanceState.toString());
        displayFirstTimeUserFragment();
//        someVarA = savedInstanceState.getInt("someVarA");
//        someVarB = savedInstanceState.getString("someVarB");
    }

    @Override
    public void onResume() {
        super.onResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }


}

这是survey_main_fragment.xml

我解决了更改片段的问题

<fragment
    android:id="@+id/fragment_survey_place"
    android:name="com.example.app.emptyFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@+id/test" />

   <FrameLayout
        android:id="@+id/fragment_survey_place"
        android:layout_width="match_parent"
        android:layout_height="match_parent" 
        android:layout_above="@+id/test"/>

到目前为止没有崩溃
