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出现问题，菜单活动很好地显示在我的选项卡下方，但是当我单击任何菜单（它将调用 LoginActivity）时，新活动将全屏显示，而不是在选项卡下。我该如何处理？下面是我的代码。
选项卡活动
package com.smartag.smarttreasure;
public class NfcSurveyActivity extends TabActivity {
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
mAdapter.enableForegroundDispatch(this, mPendingIntent, mFilters,
mTechLists);
int profileCount = db.getContactsCount();
if (profileCount <= 0) {
Intent intent = new Intent(getApplicationContext(),
LoginActivity.class);
startActivity(intent);
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
int profileCount = db.getContactsCount();
if (profileCount <= 0) {
Intent intent1 = new Intent(getApplicationContext(),
LoginActivity.class);
startActivity(intent1);
}
Bundle extras = getIntent().getExtras();
if (extras != null) {
tabToDisplay = extras.getString("tab");
if (tabToDisplay.equals("CAMERA")) {
barcodeData = extras.getString("barcodeData");
}
extras.clear();
}
TabHost tabHost = getTabHost();
// Home
TabSpec tbspecHome = tabHost.newTabSpec("Home");
tbspecHome.setIndicator("",
getResources().getDrawable(R.drawable.tab_account_style));
Intent iHome = new Intent(this, HomeActivity.class);
tbspecHome.setContent(iHome);
tabHost.addTab(tbspecHome);
// History
tabHost.addTab(tabHost
.newTabSpec("Fun")
.setIndicator("",
getResources().getDrawable(R.drawable.tab_fun_style))
.setContent(
new Intent(this, NfcSurveyActivity.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));
if (tabToDisplay != null && tabToDisplay.equals("REDEEM")) {
if (barcodeData != null && barcodeData.length() > 0) {
tabHost.addTab(tabHost
.newTabSpec("Camera")
.setIndicator(

getResources().getDrawable(
R.drawable.tab_redeem_style))
.setContent(
new Intent(this, NfcSurveyActivity.class)

Intent.FLAG_ACTIVITY_CLEAR_TOP)

barcodeData)));
}
else {
tabHost.addTab(tabHost
.newTabSpec("Camera")
.setIndicator(

getResources().getDrawable(
R.drawable.tab_redeem_style))

// tabHost.setCurrentTab(2);
tabHost.getTabWidget().getChildAt(2).getLayoutParams().height = tabHost
.getTabWidget().getChildAt(2).getLayoutParams().height + 19;
// Search
TabSpec tbspecSearch = tabHost.newTabSpec("Finder");
tbspecSearch.setIndicator("",
getResources().getDrawable(R.drawable.tab_finder_style));
Intent iSearch = new Intent(this, NfcSurveyActivity.class);
tbspecSearch.setContent(iSearch);
tabHost.addTab(tbspecSearch);
// Profile
TabSpec tbspecProfile = tabHost.newTabSpec("Quit");
tbspecProfile.setIndicator("",
getResources().getDrawable(R.drawable.tab_quit_style));
Intent iProfile = new Intent(this, NfcSurveyActivity.class);
tbspecProfile.setContent(iProfile);
tabHost.addTab(tbspecProfile);
for (int i = 0; i <= 4; i++) {
tabHost.getTabWidget()
.getChildTabViewAt(i)
.setBackgroundColor(
getResources()
.getColor(android.R.color.transparent));
if (i == 2) {
tabHost.getTabWidget()
.getChildTabViewAt(i)
.setPadding(
tabHost.getTabWidget().getChildTabViewAt(i)
.getPaddingLeft(),
tabHost.getTabWidget().getChildTabViewAt(i)
.getPaddingTop(),
tabHost.getTabWidget().getChildTabViewAt(i)
.getPaddingRight(), 20);
}
}
if (tabToDisplay != null && tabToDisplay.length() > 0) {
if (tabToDisplay.equals("CAMERA")) {
tabHost.setCurrentTab(2);
} else if (tabToDisplay.equals("HISTORY")) {
tabHost.setCurrentTab(1);
}
}
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
public void onTabChanged(String tabId) {
NfcSurveyConfiguration.SelectedTab = tabId;
}
});
}
}
菜单活动
public class HomeActivity extends ListActivity {
static final String[] Account = new String[] { "Point History", "Scan History",
"Reward/Coupon History", "Share/Transfer History", "Personalise" };
String tabToDisplay = "";
String barcodeData = "";
SharedPreferences nfcSurveyConfiguration;
String profileId;
String pleaseWait = "";
protected boolean _taken;
protected File _directory;
protected String _filename;
protected String _fileExtension;
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;
}
}
