java - 在选项卡外部调用的 Activity

Question

我正在开发一个有 5 个选项卡的应用程序，我的最后一个选项卡显示菜单列表。当我单击菜单选项卡时，会出现问题，菜单 Activity 很好地显示在我的选项卡下方，但是当我单击任何菜单(它将称为 LoginActivity)时，新 Activity 会全屏显示，而不是在选项卡下。我该如何处理这个问题？下面是我的代码。

选项卡 Activity

public class NfcSurveyActivity extends TabActivity {

    protected void onResume() {
        // TODO Auto-generated method stub

                mTechLists);

        int profileCount = db.getContactsCount();
        if (profileCount <= 0) {
            Intent intent = new Intent(getApplicationContext(),
                    LoginActivity.class);
            startActivity(intent);
        }
    }

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        int profileCount = db.getContactsCount();
        if (profileCount <= 0) {
            Intent intent1 = new Intent(getApplicationContext(),
                    LoginActivity.class);

菜单 Activity

    String profileName = "";
    String profileEmail = "";
    String profileStatus = "";
    String profileLanguage = "";
    String profileType = "";
    DatabaseHandler db = new DatabaseHandler(this);



    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter<String>(this,
                R.layout.listview_item_row, Account));

        ListView listView = getListView();

        listView.setTextFilterEnabled(true);

        listView.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // When clicked, show a toast with the TextView text
                //Toast.makeText(getApplicationContext(),
                    //  ((TextView) view).getText(), Toast.LENGTH_SHORT).show();
                Intent intent1 = new Intent(getApplicationContext(),
                        LoginActivity.class);
                startActivity(intent1); // This activity appears not in the tab             
            }
        });


    }

    @Override
    public void onPause() {
        super.onPause();
        NfcSurveyConfiguration.CurrentActiveTab = 0;
    }

}

任何建议或建议都将受到高度赞赏。

setOnItemClickListener 中的这段代码帮助我解决了问题。

View view1 = getLocalActivityManager().startActivity(
                            "ReferenceName",
                            new Intent(getApplicationContext(),
                                    YourActivityClass.class)
                                    .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
                            .getDecorView();
                    setContentView(view1);
