this is my login view http://i.imgur.com/IfLIHFQ.jpg , a successful login will redirect to this page http://i.imgur.com/4yv3KDv.jpg but, instead of launch a new intent, I want the activity is proceed within the tab. This is how I describe it http://i.imgur.com/sH8HQC7.jpg (Note: The last pic is just an edited photoshop in order to give you a sample of what I want it to be). Sorry for asking newbie question, I appreciate your help thanks before.

This is my code : Tab1.java

public class Tab1 extends Activity {
    String var_usr,var_pass;
    EditText usr, psw;
    JSONArray str_login = null;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.panel_login);

        usr = (EditText) findViewById(R.id.txt_username);
        psw = (EditText) findViewById(R.id.txt_pass);


        Button submit = (Button) findViewById(R.id.btn_login);
        submit.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {

                var_usr = usr.getText().toString();
                var_pass = psw.getText().toString();
                String stts = "";
                String kode = "";
                String link_url = "http://10.0.2.2/gollege/login.php?usr="+var_usr+"&psw="+var_pass;
                com.bucheuw.gollege.portal.JSONParser jParser = new com.bucheuw.gollege.portal.JSONParser();
                JSONObject json = jParser.AmbilJson(link_url);

                try {
                    str_login = json.getJSONArray("statuslogin");

                    for(int i = 0; i < str_login.length(); i++){
                        JSONObject ar = str_login.getJSONObject(i);
                        TextView st = (TextView) findViewById(R.id.txt_alert);
                        String alrt = ar.getString("hasil");
                        stts = ar.getString("st");
                        kode = ar.getString("id");
                        st.setText(alrt);
                        usr.setText("");
                        psw.setText("");

                        if(stts.trim().equals("ok"))
                        {
                            Intent ni = null;                           
                            ni = new Intent(Tab1.this, com.bucheuw.gollege.portal.DashboardActivity.class);
                            Bundle b = new Bundle();
                            b.putString("par_kode", kode);
                            ni.putExtras(b);
                            startActivity(ni);
                        }
                    }

在创建 tabhost 的父活动类中，我实现了如下方法：

public void switchTab(int tab){
            tabHost.setCurrentTab(tab);
}

在我希望能够在内部切换到另一个选项卡的选项卡内部，我创建了以下方法：

public void switchTabInActivity(int indexTabToSwitchTo){
            MintTrack ParentActivity;
            ParentActivity = (MintTrack) this.getParent();
            ParentActivity.switchTab(indexTabToSwitchTo);
}

如果您想要此代码的一个很好的示例，您可以在此处和此处查看我的 MintTrack 项目。

附带说明一下，在决定是使用基于视图还是基于活动的 TabHost 时，请务必小心。

基于活动的选项卡很棒，因为它们可以分离到自己的 XML 文件中。活动也可以组织到自己的 Java 文件中，而不是混乱成一个。话虽这么说，一些你认为很容易的事情会因为基于活动的选项卡而变得复杂。很难在选项卡之间传递信息而不产生开销。基于活动的选项卡也使用更多的内存/CPU 时间，因为它们有围绕它们的活动的开销。在深入使用基于 Activity 的 TabHost 之前，请考虑这一点以及更多的权衡。我现在知道，如果我再次使用它们，我会亲自使用基于视图的 TabHost。
