【Android】通过Java代码替换TabHost中的drawableTop资源
在博客 http://blog.csdn.net/jueblog/article/details/11837445 中的Tab选项卡中,
点击相应的Tab选项,图标没有发生改变。
这些资源图片也没有尽用,若要使点击选项后,图标发生改变,可以在Java代码中实现。
改变drawableTop的Java代码:
main_radio.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {@Overridepublic void onCheckedChanged(RadioGroup group, int id) {if (id == tab_icon_weixin.getId()) {tab_icon_weixin.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_weixin_pressed,0, 0);tab_icon_address.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_address_normal,0, 0);tab_icon_find.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_find_frd_normal,0, 0);tab_icon_myself.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_settings_normal,0, 0);mTabHost.setCurrentTab(0);} else if (id == tab_icon_address.getId()) {tab_icon_weixin.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_weixin_normal,0, 0);tab_icon_address.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_address_pressed,0, 0);tab_icon_find.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_find_frd_normal,0, 0);tab_icon_myself.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_settings_normal,0, 0);mTabHost.setCurrentTab(1);} else if (id == tab_icon_find.getId()) {tab_icon_weixin.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_weixin_normal,0, 0);tab_icon_address.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_address_normal,0, 0);tab_icon_find.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_find_frd_pressed,0, 0);tab_icon_myself.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_settings_normal,0, 0);mTabHost.setCurrentTab(2);} else if (id == tab_icon_myself.getId()) {tab_icon_weixin.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_weixin_normal,0, 0);tab_icon_address.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_address_normal,0, 0);tab_icon_find.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_find_frd_normal,0, 0);tab_icon_myself.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_settings_pressed,0, 0);mTabHost.setCurrentTab(3);}}});从而可以得到想要的切换效果。
