Android EditText Soft Keyboard some summary

See a manifest in the activity configuration, if this page has edittext, and we want to enter this page by default pop-up input method, you can set this zodiac: android:windowsoftinputmode= Statevisible, this will be the default pop-up input method, of course, there are other ways.

1. <activity android:name=". Ui.login"
2. android:configchanges="Orientation|keyboardhidden|locale"
3. android:screenorientation="Portrait"
4. Android:windowsoftinputmode="Statevisible|adjustpan" >
5. </activity>

Android EditText Not Popup Input Method summary

Method One:

Which activity to select in Androidmainfest.xml, set Windowsoftinputmode property to Adjustunspecified|statehidden

For example:

1. <activity android:name=". Main "
2. Android:label="@string/app_name"
3. Android:windowsoftinputmode="Adjustunspecified|statehidden"
4. android:configchanges="Orientation|keyboardhidden" >
5. < intent-filter>
6. < action android:name="Android.intent.action.MAIN"/>
7. < category android:name="Android.intent.category.LAUNCHER"/>
8. </intent-filter>
9. </activity>

Method Two:

Let EditText lose focus, use EditText's Clearfocus method

For example:

1. EditText edit= (EditText) Findviewbyid (R.id.edit);
2. Edit.clearfocus ();

Method Three:

Force Hide Android IME window

For example:

1. EditText edit= (EditText) Findviewbyid (R.id.edit);
2. Inputmethodmanager IMM = (inputmethodmanager) getsystemservice (Context.input_method_service);
3. Imm.hidesoftinputfromwindow (Edit.getwindowtoken (),0);

2.EditText always does not eject the software keyboard

Cases:

1. EditText edit= (EditText) Findviewbyid (R.id.edit);
2. Edit.setinputtype (Inputtype.type_null);

The problem of focus and popup input method in Android was studied. Some of the examples on the Internet are not comprehensive enough to summarize here.

A: Why does the edittext default pop-up input method?

The same code, touch the interface with the EditText control when some of the machine will pop-up input method, some of the machine will not pop up. Sorry, this question I also confused, who knows can tell me, otherwise I will leave this question, later study the Android source code to make a clear. But... I have a solution.

Two: Default popup and default turn off the IME solution.

1. Default off, do not enter the activity to open the input method, the impact of beautiful interface.

① in the layout file, place an invisible linearlayout in front of the edittext, allowing him to take the lead in getting the focus:

1. <linearlayout
2. android:focusable="true"
3. Android:focusableintouchmode="true"
4. android:layout_width="0px"
5. android:layout_height="0px"/>

② method Two: First look at a property Android:inputtype: Specify the type of input method, int type, you can select more than one. The value can be referenced by: Android.text.InputType class. The values include: Text,texturi,

Phone,number, et.

In the Android SDK there is such a phrase "If the given content type is Type_null then a soft keyboard would not be displayed for this text view",

First change the EditText inputtype to Type_null, the input method will not pop up. Then set the listener, and then reset its inputtype.

2. Edittext.setontouchlistener (new Ontouchlistener () {
4. Public Boolean OnTouch (View V, motionevent event) {
6. //TODO auto-generated method stub
8. int intype = Edittext.getinputtype (); //backup the input type
10. Edittext.setinputtype (Inputtype.type_null); //Disable soft input
12. Edittext.ontouchevent (event); //Call native handler
14. Edittext.setinputtype (Intype); //Restore input type
16. return true;
18. }
20. });

2. Default Popup. Sometimes, you may require the default popup input method as required. The scheme is as follows:

2. EditText titleinput = (EditText) Findviewbyid (r.id.create_edit_title);
4. Titleinput.setfocusable (true);
6. Titleinput.requestfocus ();
8. Onfocuschange (titleinput.isfocused ());
10. Private void Onfocuschange (boolean hasfocus)
12. {
14. Final Boolean isfocus = Hasfocus;
16. (new Handler ()). postdelayed (new Runnable () {
18. Public void Run () {
20. Inputmethodmanager IMM = (Inputmethodmanager)
22. Titleinput.getcontext (). Getsystemservice (Context.input_method_service);
24. if (Isfocus)
26. {
28. Imm.togglesoftinput (0, inputmethodmanager.hide_not_always);
30. }
32. Else
34. {
36. Imm.hidesoftinputfromwindow (Titleinput.getwindowtoken (),0);
38. }
40. }
42. }, 100);
44. }

I think that because the operation of the UI is invalid in the main thread of Android, it is necessary to implement the popup input method in handler.

Three: Personal understanding of focus and Input method

Get focus is to get focus, bouncing input method is bouncing input method. Get focus after not sure will pop-up input method, in the online search a circle, the mainstream answer is "There is open interface is the text of the focus is also not possible, UI rendering is required time" ...

Because I do not understand the source code, I do not have a comprehensive understanding of this point. Only focus and input methods can be divided into two blocks to handle. Focus opening and closing is particularly straightforward.

Acquisition of Focus:

1. Titleinput.setfocusable (true);
2. Titleinput.requestfocus ();

Cancellation of Focus:

1. Titleinput.setfocusable (false);

Four: The functions of handling soft keyboards that are often called are as follows:

1. Open the Input Method window:

1. Inputmethodmanager Inputmethodmanager = (inputmethodmanager) getsystemservice (Context.input_method_service);
2. Edit text or other views that accept soft keyboard input
3. Imm.showsoftinput (submitbt,inputmethodmanager.show_forced);

2. Close the Access Law window

1. Inputmethodmanager Inputmethodmanager = (inputmethodmanager) getsystemservice (Context.input_method_service);
2. Inputmethodmanager.hidesoftinputfromwindow (opelistactivity. This.getcurrentfocus (). Getwindowtoken (),
3. Inputmethodmanager.hide_not_always);
4. Edit text or other views that accept soft keyboard input
5. Inputmethodmanagerwww.2cto.com
6. . Showsoftinput (submitbt,inputmethodmanager.show_forced);

3, if the input method is turned off, if not open then open

1. Inputmethodmanager m= (Inputmethodmanager) Getsystemservice (Context.input_method_service);
2. M.togglesoftinput (0, inputmethodmanager.hide_not_always);

4, get the input method open state

1. Inputmethodmanager IMM = (inputmethodmanager) getsystemservice (Context.input_method_service);
2. Boolean isopen=imm.isactive ();

IsOpen returns true to indicate that the input method is open
