Are you hungry? Wait for app bottom menu (fragment implementation)

Fragment implementation of the bottom menu navigation, is now a lot of apps have a function, the effect is to click the menu, the menu to implement the icon and color transformation

There are two main ways to achieve this, one is tabhost and the other is the fragment after Android3.0

Fragment, need to add V4 price pack

Then icon icons then, need to do it yourself, or go to http://www.iconfont.cn/, Ali's Gallery download

There are two icons for the bottom menu, one is the default icon, and one is the icon after the menu is clicked.

Ui:

<linearlayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:custom= "http// Schemas.android.com/apk/res-auto "android:layout_width=" match_parent "android:layout_height=" Match_parent "Androi D:background= "#FFFFFF" android:orientation= "vertical" > <framelayout android:layout_width= "Match_par         Ent "android:layout_height=" 0DP "android:layout_weight=" 3 "android:id=" @+id/fg_content "/> <view android:layout_width= "match_parent" android:layout_height= "0.2DP" android:background= "@co Lor/bg_gray "/> <radiogroup android:layout_width=" match_parent "android:layout_height=" wrap_content "Android:background=" @color/white "android:gravity=" center_vertical "android:orientation=" Horizontal            "> <radiobutton android:id=" @+id/rb_homepage "android:layout_width=" Wrap_content "   android:layout_height= "Wrap_content"         android:button= "@null" android:drawabletop= "@drawable/guide_homepage" android:gravity= "cent            Er_horizontal "android:onclick=" onhomepageclicked "android:text=" @string/fragment_menu_homepage "            Android:textcolor= "@color/tab_text_bg"/> <radiobutton android:id= "@+id/rb_order" Android:layout_width= "Wrap_content" android:layout_height= "Wrap_content" android:button= " @null "android:drawabletop=" @drawable/guide_order "android:gravity=" Center_horizontal "an droid:onclick= "onorderclicked" android:text= "@string/fragment_menu_order" android:textcolor= "@color/ Tab_text_bg "/> <radiobutton android:id=" @+id/rb_found "android:layout_width=" Wrap_cont Ent "android:layout_height=" wrap_content "android:button=" @null "android:drawabletop=" @dr     Awable/guide_found "       Android:gravity= "Center_horizontal" android:onclick= "onfoundclicked" android:text= "@string/fr Agment_menu_found "android:textcolor=" @color/tab_text_bg "/> <radiobutton Andro            Id:id= "@+id/rb_my" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" android:button= "@null" android:drawabletop= "@drawable/guide_my" android:gravity= "Center_horizonta L "android:onclick=" onmyclicked "android:text=" @string/fragment_menu_my "Android:textcolo R= "@color/tab_text_bg"/> </RadioGroup> </LinearLayout>
