How do you implement a conjugate between buttons in a custom control?

Problem: Layout

Control Bottomlayout to three ImageButton below

Intent: The three buttons below are implemented as moments and only one is selected (similar to Weibo)

The simplest solution:

1  PackageCom.example.weibo;2 3 ImportAndroid.content.Context;4 ImportAndroid.util.AttributeSet;5 ImportAndroid.view.LayoutInflater;6 ImportAndroid.view.View;7 ImportAndroid.widget.ImageButton;8 Importandroid.widget.LinearLayout;9 Ten  One  Public classBottomlayoutextendsLinearLayout { A     PrivateImageButton main; -     PrivateImageButton add; -     PrivateImageButton account; the      -     Final intHome_b =R.DRAWABLE.IC_HOME_BLACK_48DP; -     Final intHome_g =R.DRAWABLE.IC_HOME_GREY600_48DP; -     Final intAdd_b =R.DRAWABLE.IC_ADD_CIRCLE_BLACK_48DP; +     Final intAdd_g =R.DRAWABLE.IC_ADD_CIRCLE_GREY600_48DP; -     Final intAccount_b =R.DRAWABLE.IC_ACCOUNT_BOX_BLACK_48DP; +     Final intAccount_g =R.DRAWABLE.IC_ACCOUNT_BOX_GREY600_48DP; A      at      Publicbottomlayout (Context context,attributeset attrs) { -         Super(context,attrs); -Layoutinflater.from (context).

Setimageresource (Home_b); theV.settag ("B"); + Add.setimageresource (add_g); -Add.settag ("G"); $ Account.setimageresource (account_g); $Account.settag ("G"); -                 } -             } the         }); -Add.setonclicklistener (NewOnclicklistener () {Wuyi @Override the              Public voidOnClick (View v) { -                 if(V.gettag () = = "G") Wu                 { - ( (ImageButton) v).

Setimageresource (account_b); -V.settag ("B"); in Add.setimageresource (add_g); theAdd.settag ("G"); the Main.setimageresource (home_g); AboutMain.settag ("G"); the                 } the             } the         }); +      -     } the}

But it doesn't seem to mean anything, so tomorrow we'll see if there's any good plan.
