Question

我的信息中心中有3个标签，即

邀请
事件
GROUPCHAT

我以编程方式添加了所有这些标签，在我的布局代码id:tabContent中使用添加所有标签。我的 Userdashboard.xml 代码位于下方，

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1" />

    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="-4dp"
        android:layout_weight="0" />

</LinearLayout>

在下面的代码中，所有标签都被分组为＆＃34; tabHost＆＃34;。现在我需要为所有三个标签设置唯一ID，但我不知道如何设置唯一ID，请提前感谢。

public class UserDashBoardActivity extends ActionBarActivity {

    /** Called when the activity is first created. */
    private static final String TAB_1_TAG = "Invitation";
    private static final String TAB_2_TAG = "Event";
    private static final String TAB_3_TAG = "GroupChat";
    private FragmentTabHost tabHost;

    private Context context;
    private SharedPreferences sharedpreferences;
    private Gson gson = new Gson();
    private Menu menu;

    @Override
    protected void onStart() {
        super.onStart();
        AppActivityStatus.setActivityStarted();
        AppActivityStatus.setActivityContext(context);
    }

    @Override
    protected void onPause() {
        super.onPause();
        AppActivityStatus.setActivityStoped();

    }

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

    @Override
    protected void onStop() {
        super.onStop();
        AppActivityStatus.setActivityStoped();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        this.menu=menu;
        getMenuInflater().inflate(R.menu.menu_user_dash_board, menu);
        return true;
        //return super.onCreateOptionsMenu(menu);
    }
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.user_dash_board);
        context = getApplicationContext();
        sharedpreferences = context.getSharedPreferences(Constants.SHARED_PREFERENCE_NAME,
                Context.MODE_PRIVATE);
        // Get TabHost Reference
        tabHost= (FragmentTabHost) findViewById(android.R.id.tabhost);
        tabHost.setup(this, getSupportFragmentManager(), android.R.id.tabcontent);

       **Invitation,Event,Groupchat tabs** are added here    

    tabHost.addTab(tabHost.newTabSpec(TAB_1_TAG).setIndicator("Invitation"), InvitationFragment.class, null);
    tabHost.addTab(tabHost.newTabSpec(TAB_2_TAG).setIndicator("Event"), OccasionFragment.class, null);
    tabHost.addTab(tabHost.newTabSpec(TAB_3_TAG).setIndicator("GroupChat"), GroupChatFragment.class, null);

        //invitation tab highlighted by default
        tabHost.getTabWidget().setCurrentTab(0);
        tabHost.getTabWidget().getChildAt(0).setBackgroundColor(getResources().getColor(R.color.Orange));
        tabHost.getTabWidget().getChildAt(1).setBackgroundColor(getResources().getColor(R.color.scandal));
        tabHost.getTabWidget().getChildAt(2).setBackgroundColor(getResources().getColor(R.color.scandal));


        //onTabChangedListener added for move one tab to others

        tabHost.setOnTabChangedListener(new OnTabChangeListener() {

            @Override
            public void onTabChanged(String arg0) {
                   setTabColor(tabHost);
            }
        });


    }
        if(tabHost.getCurrentTab()==0)
        tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(getResources().getColor(R.color.Orange));//1st tab selected
        else if(tabHost.getCurrentTab()==1)
        tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(getResources().getColor(R.color.Orange)); //2nd tab selected
        else if(tabHost.getCurrentTab()==2)
        tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(getResources().getColor(R.color.Orange)); //3rd tab selected
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();
        // noinspection SimplifiableIfStatement
        if (id == R.id.account_settings) {
            Intent userSettingIntent = new Intent(getApplicationContext(),ActivityUserSettings.class);
            userSettingIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(userSettingIntent);
            return true;
        }

        if (id == R.id.profile) {
            Intent profileIntent = new Intent(getApplicationContext(),ImageUploadActivity.class);
            profileIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(profileIntent);
            return true;
        }

        if(id == R.id.create_occasion){

            Intent occasionAct = new Intent(getApplicationContext(), OccasionActivity.class);
            // Clears History of Activity
            occasionAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(occasionAct);

        }
        return super.onOptionsItemSelected(item);
    }

}

对tabHost.newTabSpec()的调用将String作为标记。在您的情况下，这些是TAB_1_TAG，TAB_2_TAG，TAB_3_TAG，因此这些是您分别为每个标签的唯一ID。

您可以在onTabChanged(String arg0) arg0中识别所选标签tabHost.getCurrentTabTag()是所选标签的名称。

此外，您可以使用tabHost.getCurrentTab()按标签标识标签，而不是按标签位置标识.wrapper, .header, .content, .footer { width: 100%; } .header { height: 70px; background: orange; } .footer { background: lightblue; } .content { background: yellow; }。
