Android edittext Settings (RPM)

1, enter the input key icon settings:

The interface of the software disk is replaced with only one attribute android:imeoptions, the value of this property can be Normal,actionunspecified,actionnone,actiongo,actionsearch, Actionsend,actionnext,actiondone, For example, the Enter key appearance becomes a down arrow when the value is Actionnext, and the ENTER key looks like a "complete" two characters when the values are actiondone.
We can also override the Enter event

The ENTER key of the soft keyboard displays the "Done" text by default, and the default "Finish" text is changed by setting Android:imeoptions. Here are some common constant values:

actionunspecified unspecified, corresponding constant editorinfo.ime_action_unspecified.
Actionnone no action, corresponding constant Editorinfo.ime_action_none
Actiongo, corresponding constant editorinfo.ime_action_go
Actionsearch search, corresponding constant editorinfo.ime_action_search
Actionsend send, corresponding constant editorinfo.ime_action_send
Actionnext Next, corresponding constant Editorinfo.ime_action_next
Actiondone complete, corresponding constant Editorinfo.ime_action_done

(Editorinfo.inputtype & Editorinfo.type_class_mask) can be a number of different values, including:
Type_class_number
Type_class_datetime
Type_class_phone
Type_class_text

2, Event capture processing:

Event handling can be set through Setoneditoractionlistener.

Final EditText input = new EditText (this);   Input.setsingleline (TRUE); Android:singleline= "true"     input.setimeoptions (editorinfo.ime_action_send);     Input.setinputtype (Inputtype.type_class_text | Inputtype.type_text_variation_password);     Input.setoneditoractionlistener (New Textview.oneditoractionlistener () {public         Boolean oneditoraction (TextView V, int ActionId,                   keyevent event)  {            log.d (TAG, "" +actionid+ "," +event ");             if (Actionid==editorinfo.ime_action_send                  | | (Event!=null&&event.getkeycode () = = Keyevent.keycode_enter)) {                //do something;              return true;             }               return false;           }       

3, editor password hidden, how to write?

There are 2 ways to handle:

Code method: Input.setinputtype (Inputtype.type_class_text | Inputtype.type_text_variation_password);

Layout Configuration method: Android:inputtype= "Textpassword"

4. When the activity is loaded, the Edit input box will automatically eject the input method, which can be masked by the following code:

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

5, set EditText always does not eject the software keyboard
Example: EditText edit= (EditText) Findviewbyid (R.id.edit);
Edit.setinputtype (Inputtype.type_null);

6, let EditText lose focus, use EditText Clearfocus method
For example: EditText edit= (EditText) Findviewbyid (R.id.edit);
Edit.clearfocus ();

7, edittext default does not eject the software keyboard

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

< activity android:name= ". Main "android:label=" @string/app_name "android:windowsoftinputmode=" Adjustunspecified|statehidden "Android: Configchanges= "Orientation|keyboardhidden" >< intent-filter>< action android:name= " Android.intent.action.MAIN "/>< category android:name=" Android.intent.category.LAUNCHER "/></ intent-filter></activity>

8. Set the cursor to the specified position

EditText et = (EditText) Findviewbyid (r.id.ettest); et.setselection (2);

  //setting cursor does not display, but cannot set cursor color   
 Et. Setcursorvisiblefalse 
 //Get focus Full text  
 Et.true 
 ET. requestfocus (;   //request to get focus   
 ET. clearfocus (; / /clear Focus 
 
 Use edittext seterror hint 
           

Et. seterror("email")     

  

SetError Tips for customizing icons

Drawable dr = Getresources (). getdrawable (R.drawable.ic_launcher);d r.setbounds (0, 0, 10, 10); The size must be set, otherwise the Et.seterror ("with Error Prompt", DR) is not displayed;

  et. Setinputtype ; You can only enter the phone number 
 Et.             //Enter only numbers 
 Et.;//can only enter e-mail address 
 Et.; //forbidden Input (Input Method not popup) 
 
 XML Implementation Case   

<edittext android:id= "@+id/ettest" android:inputtype= "number"       android:layout_width= "Wrap_content        " android:layout_height= "Wrap_content"/>
