TabHost.setCurrentTab() 方法无效

Question

I am using TabHost and I have to change the default Tabselected according to the users selected option in previous class but it is not working.

这是我的代码。

 public class FirstActivity extends FragmentActivity {

        private FragmentTabHost mTabHost;
        String getselectevalue ="0";

         private static final String TAB_1_TAG = "tab_1";
         private static final String TAB_2_TAG = "tab_2";
         private static final String TAB_3_TAG = "tab_3";
         private static final String TAB_4_TAG = "tab_4";
         private static final String TAB_5_TAG = "tab_5";


        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.bottom_tabs);

            InitView();
            getActionBar().setDisplayHomeAsUpEnabled(true);

            // mTabHost = new FragmentTabHost(this);
            // mTabHost.setup(this, getSupportFragmentManager(),
            // R.id.menu_settings);

            try{
            getselectevalue = getIntent().getExtras().getString("selectedVlaue");
            }catch(Exception e){

            }

            Log.d("got the value here", getselectevalue);


        }

         private void InitView() {
              mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
                    mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);


                    mTabHost.addTab(setIndicator(FirstActivity.this,mTabHost.newTabSpec(TAB_1_TAG),
                            R.drawable.tab_indicator_gen,"Post",R.drawable.post_unselected),Fragment1.class,null);
                    mTabHost.addTab(setIndicator(FirstActivity.this,mTabHost.newTabSpec(TAB_2_TAG),
                              R.drawable.tab_indicator_gen,"Profile",R.drawable.profile_unselect),Fragment2.class,null);
                    mTabHost.addTab(setIndicator(FirstActivity.this,mTabHost.newTabSpec(TAB_3_TAG),
                              R.drawable.tab_indicator_gen,"Chat",R.drawable.chat_unselected),Fragment3.class,null);
                    mTabHost.addTab(setIndicator(FirstActivity.this,mTabHost.newTabSpec(TAB_4_TAG),
                              R.drawable.tab_indicator_gen,"Event",R.drawable.event_unselcted),Fragment3.class,null);
                    mTabHost.addTab(setIndicator(FirstActivity.this,mTabHost.newTabSpec(TAB_5_TAG),
                              R.drawable.tab_indicator_gen,"Fragment",R.drawable.shop_unselected),Fragment3.class,null);


                       if(getselectevalue.equalsIgnoreCase("0")){

                        mTabHost.setCurrentTab(0);

                        }else{

                            mTabHost.setCurrentTab(1);
                        }
               }



             private TabSpec setIndicator(Context ctx, TabSpec spec,
               int resid, String string, int genresIcon) {
                  View v = LayoutInflater.from(ctx).inflate(R.layout.tab_item, null);
                  v.setBackgroundResource(resid);
                  TextView tv = (TextView)v.findViewById(R.id.txt_tabtxt);
                  ImageView img = (ImageView)v.findViewById(R.id.img_tabtxt);

                  tv.setText(string);
                  img.setBackgroundResource(genresIcon);
                  return spec.setIndicator(v);
             }

Please have a look and let me know what mistake I am doing here.

首先在catch block之后调用InitView();方法。

 try 
    {
    getselectevalue = getIntent().getExtras().getString("selectedVlaue");
    }catch(Exception e)
    {

    }
   InitView();
