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));
}
}

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
}
