修改Tabhost樣式和字型大小和居中顯示

有時候我們的tabhost并不需要貼圖，是以這個時候就必須把文字居中顯示和設定大小了，代碼如下

setContentView(R.layout.home_vzo_tabhost);

        tabHost = getTabHost();

        tabWidget = tabHost.getTabWidget();

        TabHost.TabSpec spec;

        Intent intent;

        //indicator訓示器

        intent = new Intent(this,HomeVzoBasicInfoActivity.class);  //把值傳給啟動的界面

        //名字；要顯示的字元；設定動畫

        spec = tabHost.newTabSpec("a1").setIndicator(getResources().getString(R.string.baseInfo))

                .setContent(intent);//設定一個Acitivity

        tabHost.addTab(spec);

        intent = new Intent(this,HomeVzoContentActivity.class);

        spec = tabHost.newTabSpec("a2").setIndicator(getResources().getString(R.string.myPull))

                .setContent(intent);

        tabHost.setOnTabChangedListener(this);

        tabHost.addTab(spec);

        for (int i =0; i < tabWidget.getChildCount(); i++) {  

            //修改Tabhost高度和寬度

//            tabWidget.getChildAt(i).getLayoutParams().height = 30;  

//            tabWidget.getChildAt(i).getLayoutParams().width = 65;

            //修改顯示字型大小

            TextView tv = (TextView) tabWidget.getChildAt(i).findViewById(android.R.id.title);

            tv.setTextSize(18);

            RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) tv.getLayoutParams();

            params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 0); //取消文字底邊對齊

            params.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE); //設定文字居中對齊

        }

        tabHost.setCurrentTab(0);
