Android将Activity集成到Fragment中

Question

我正在开发一个显示听力测试结果的Android应用程序。它是在不久前制作的，所以很多代码都被折旧了。旧代码使用TabActivity，效果很好：

public class TabbedResultActivity extends TabActivity {
private TabHost mTabHost;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.tabbed_results);

    setTabs();
}

private void setTabs() {
    mTabHost = getTabHost();

    addTab(R.string.Left_ear, false);
    addTab(R.string.Right_ear, true);
}

private void addTab(int labelId, boolean aRight) {
    Intent intent = createIntent(aRight);
    TabHost.TabSpec spec = mTabHost.newTabSpec("tab" + labelId);        

    View tabIndicator =     LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false);

    TextView title = (TextView) tabIndicator.findViewById(R.id.title);
    title.setTextSize(14.0f);
    title.setText(labelId);

    spec.setIndicator(tabIndicator);
    spec.setContent(intent);
    mTabHost.addTab(spec);
}

private Intent createIntent( boolean aRight) {
    Intent newIntent = new Intent(getIntent());
    newIntent.putExtra(ResultActivity.IS_RIGHT_EAR, aRight);
    newIntent.setClass(this, ResultActivity.class);
    return newIntent;
}   

但问题是，我必须在新设备上为菜单添加操作栏。为了使应用程序在所有设备上兼容，我使用了ActionBarSherlock库。这很棒，但我无法弄清楚如何将ResultsActivity添加到片段中，因为我需要ResultsActivity从SherlockFragmentActivity扩展，但要将其集成到片段中，我需要扩展SherlockFragment类。如果我这样做，我会收到很多错误，因为它不会从活动中延伸出来。这是我原来的ResultsActivity课程：

public class ResultActivity extends SherlockFragmentActivity {
public static final String IS_RIGHT_EAR = "is_right_ear";
private ArrayList<EarSrt> leftAnswerList;
private ArrayList<EarSrt> rightAnswerList;

private boolean isRightEarTab = true;

private boolean bothEarsBad;
private boolean leftEarBad;
private boolean rightEarBad;


@SuppressWarnings("unchecked")
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.results_layout);

    Intent intent = getIntent();
    int rowId = intent.getIntExtra(ResultsDatabase._ID, -1);
    if ( rowId != -1 ) {
        ResultsDatabase db = new ResultsDatabase(this);
        String select = "(" + ResultsDatabase._ID + " == " + rowId + ")";
        Cursor c = db.getReadableDatabase().query(ResultsDatabase.TABLE_NAME, null, select, null, null, null,null);
        if ( c.moveToFirst() ) {
            int leftEarColumn = c.getColumnIndex(ResultsDatabase.LEFT_EAR);
            byte[] leftEarByteArray = c.getBlob(leftEarColumn);
            int rightEarColumn = c.getColumnIndex(ResultsDatabase.RIGHT_EAR);
            byte[] rightEarByteArray = c.getBlob(rightEarColumn);
            leftAnswerList = (ArrayList<EarSrt>) ResultsDatabase.deserializeObject(leftEarByteArray);
            rightAnswerList = (ArrayList<EarSrt>) ResultsDatabase.deserializeObject(rightEarByteArray);
        }

    } else {
        byte[] leftEarByteArray = getIntent().getByteArrayExtra(ResultsDatabase.LEFT_EAR);;
        byte[] rightEarByteArray = getIntent().getByteArrayExtra(ResultsDatabase.RIGHT_EAR);
        leftAnswerList = (ArrayList<EarSrt>) ResultsDatabase.deserializeObject(leftEarByteArray);
        rightAnswerList = (ArrayList<EarSrt>) ResultsDatabase.deserializeObject(rightEarByteArray);
    }

    isRightEarTab = getIntent().getBooleanExtra(IS_RIGHT_EAR, true);

    GraphView graphView = (GraphView)findViewById(R.id.graphview);

    if ( isRightEarTab ) {
        graphView.setPoints(rightAnswerList);
        float average = calculateAverage(rightAnswerList);
        graphView.setAverage(average);
    } else {
        graphView.setPoints(leftAnswerList);
        float average = calculateAverage(leftAnswerList);
        graphView.setAverage(average);
    }

    setResults(leftAnswerList, rightAnswerList);
}

private float calculateAverage(List<EarSrt> steps) {
    float srt = 0.0f;
    int length = steps.size();

    for (int i = (int)Math.ceil( (float)length/(float)2); i < length; i++) {
        EarSrt es = steps.get(i);
        srt += es.getSrt();

        //printf("%f ," , [es srt]);
    }

    srt = srt / (length-(float)Math.ceil( (float)length/(float)2));

//      printf("\n%f\n" , srt);

    return srt;
}

private void setResults(List<EarSrt> leftEar, List<EarSrt> rightEar) {
    float esLeft = calculateAverage(leftEar);
    float esRight = calculateAverage(rightEar); 

    leftEarBad = (esLeft > 24.0);
    rightEarBad = (esRight > 24.0);
    bothEarsBad = (leftEarBad && rightEarBad);

    setResultCaption(bothEarsBad, leftEarBad, rightEarBad);
}


/**
 * TODO: this needs finishing
 */
private void setResultCaption(boolean bothEarsBad, boolean leftEarBad, boolean rightEarBad) {
    TextView resultsTextView = (TextView)findViewById(R.id.results_text);
    StringBuilder resultsText = new StringBuilder();
    if (bothEarsBad) {
        resultsText.append(getString(R.string.The_test_indicates_a_possible_hearing_loss));
        resultsText.append(getString(R.string.We_recommend_that_you_visit_a_Hearing_Care_Professional_for_a_comprehensive_hearing_check));
    }else{
        if (leftEarBad) {
            resultsText.append(getString(R.string.The_test_indicates_a_possible_hearing_loss_for_your_left_ear));
            resultsText.append(getString(R.string.We_recommend_that_you_visit_a_Hearing_Care_Professional_for_a_comprehensive_hearing_check));
        } else if (rightEarBad) {
            resultsText.append(getString(R.string.The_test_indicates_a_possible_hearing_loss_for_your_Right_ear));
            resultsText.append(getString(R.string.We_recommend_that_you_visit_a_Hearing_Care_Professional_for_a_comprehensive_hearing_check));      
        }else {
            resultsText.append(getString(R.string.There_is_no_indication_of_hearing_loss));
        }                               
    }

    resultsText.append(getString(R.string.The_results_of_the_hearing_test_are_not_to_be_utilized_as_an_official_outcome_for_assessing_levels_of_hearing_loss_True_hearing_loss_assessments_can_only_be_determined_by_a_licensed_hearing_healthcare_provider));                                  

    resultsTextView.setText(resultsText.toString());
}

public void goToLocate(View aView){
    Intent locate = new Intent( this, LocateActivity.class);
    startActivity(locate);
    finish();
}
}

我基本上需要将此代码集成到两个片段中，一个用于左耳，一个用于右耳。我已经去看了Sherlock碎片样本，但仍然无法弄清楚如何去做。如果有人能指出我正确的方向，那将是非常有帮助的。

提前致谢。
