设置TabWidget的样式的方法、关联Fragment与tabwidget的方法、点击tab显示相应Fragment方法

private void updateTabHost(TabHost tabHost) {
        int count = tabHost.getTabWidget().getChildCount();
        for (int i = 0; i < count; i++) {
            View view = tabHost.getTabWidget().getChildTabViewAt(i);
            int tabHeightPx = DisplayUtil.dp2px(this, 80 // tab高度，此处单位为dp，经过DisplayUtil后转为px然后赋值
                    );
            view.getLayoutParams().height = tabHeightPx; // tabWidget.getChildAt(i)
            final TextView tv = (TextView) view
                    .findViewById(android.R.id.title);
            tv.setTextSize(28);
            tv.setTextColor(this.getResources().getColorStateList(
                    android.R.color.white));
        }
    }

这是更改其tabwidget样式的方法

private void changeLayout() {
        // 根据用户的点击位置的下标显示相应的fragment
        tabHost.setCurrentTab(currentlayout);
    }

    private void setFragment() {
        // 通过组件的id初始化tabHost的实例
        tabHost = (TabHost) findViewById(R.id.tabhost);
        tabHost.setup();
        // tabWidget = tabHost.getTabWidget();
        // 往tabHost分别添加fragment
        tabHost.addTab(tabHost
                .newTabSpec("main_social")
                .setIndicator(
                        "动态",
                        this.getResources().getDrawable(
                                R.drawable.checkbox_full_pressed))
                .setContent(R.id.frag_social));
        tabHost.addTab(tabHost
                .newTabSpec("main_geomark")
                .setIndicator(
                        "联系人",
                        this.getResources().getDrawable(
                                R.drawable.checkbox_full_pressed))
                .setContent(R.id.frag_geomark));
        tabHost.addTab(tabHost
                .newTabSpec("main_timeaxis")
                .setIndicator(
                        "动态",
                        this.getResources().getDrawable(
                                R.drawable.checkbox_full_pressed))
                .setContent(R.id.frag_timeaxis));

        tabHost.addTab(tabHost
                .newTabSpec("main_travel")
                .setIndicator(
                        "设置",
                        this.getResources().getDrawable(
                                R.drawable.checkbox_full_pressed))
                .setContent(R.id.frag_travel));

        tabHost.addTab(tabHost
                .newTabSpec("main_activity")
                .setIndicator(
                        "设置",
                        this.getResources().getDrawable(
                                R.drawable.checkbox_full_pressed))
                .setContent(R.id.frag_activity));

        updateTabHost(tabHost);//更新布局样式等
        
        tabHost.setCurrentTab(0);// 设置默认显示布局
    }

这是关联Fragment和tabWidget点击的方法，此方法放在onCreate方法内~
