Custom edittext with the delete button

With the Clear button, you can add images to the left and right sides. By default, the clear button is added.

Clearing the content is the range of the judgment gesture to click edittext.

The custom edittext code is as follows:

Import android. content. context; import android. graphics. drawable. drawable; import android. text. editable; import android. text. textutils; import android. text. textwatcher; import android. util. attributeset; import android. view. motionevent; import android. view. view; import android. widget. edittext;/*** created by Administrator on 2014/9/15. */public class clearedittext extends edittext implements textwatcher, view. onfocuschangelistener {/*** image resources on both sides */private drawable left, right;

        /** 

* You can add clearlistener to clear the data on the following page.

         */ 

Private clearlistener mclearlistener;/*** indicates whether to obtain the focus. By default, no focus */private Boolean hasfocus = false; /*** X coordinate when the finger is lifted */private int xup = 0; private Boolean hasmylistener = false; public interface clearlistener {public void dochange ();} public void setmylistener (clearlistener) {mclearlistener = clearlistener; hasmylistener = true;} public clearedittext (context) {This (context, NUL L);} public clearedittext (context, attributeset attrs) {This (context, attrs, android. r.
