Android interface Hide soft keyboard exploration (and Findviewbyid return null resolution)

Recently wrote the app, the teacher said my landing interface although there is scrollview sliding, but the user experience is not very good, because the soft keyboard will block the input box or login button (mi pad, horizontal screen, when the specified can only enter the number when not found to close the system with the keyboard down arrow).

Although I think ScrollView is enough, can find the login button ...

In Silent spit groove under even sogou have the function of millet no after, search the next solution on the Internet.

First, when the activity load is complete, the mask edittext automatically eject the soft keyboard, need a word:

1 GetWindow (). Setsoftinputmode (WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

Of course it needs to be used after setcontentview;

Then, referring to a wide range of examples on the web, give the root layout ID and allow click:

1 <?XML version= "1.0" encoding= "Utf-8"?>2 <LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"3 Android:id= "@+id/user_info_add"4 Android:layout_width= "Match_parent"5 Android:layout_height= "Match_parent" 6 Android:background= "@color/white_color"7 android:clickable= "true"8 android:orientation= "vertical">9 Ten <!--Middle omitted - One  A </LinearLayout>

Then add the response code to the corresponding activity and respond to the click:

1Ll_login =(LinearLayout) Findviewbyid (r.id.ll_activity_login);2         /*Click the blank area to turn off the soft keyboard*/3Ll_login.setonclicklistener (NewOnclicklistener () {4 @Override5              Public voidOnClick (View v) {6                 Switch(V.getid ()) {7                  CaseR.id.ll_activity_login:8Inputmethodmanager imm2 =(Inputmethodmanager)9 Getsystemservice (context.input_method_service);TenImm2.hidesoftinputfromwindow (V.getwindowtoken (), 0); One                      Break; A                 } -  -             } the});

Think it's time to do it, click on it and find the soft keyboard can't be turned off!

Check again, the problem is ScrollView, he will block this click event. The solution is not no, but the few found have a certain impact on ScrollView and internal component click Operations (￣_￣| | |)

Since the soft keyboard can be hidden, what you use, delete (╯‵-′) ╯︵┻━┻

Last Test, no problem, everything is normal ~
