Edittext Control for Android

Package ZM. DMY; import android. app. activity; import android. OS. bundle; import android. view. keyevent; import android. view. view; import android. view. view. onkeylistener; import android. widget. edittext; import android. widget. textview; public class editview1activity extends activity {/** called when the activity is first created. */private textview textview1; private edittext edittext1; @ override public void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); setcontentview (R. layout. main); textview1 = (textview) findviewbyid (R. id. mytextview); edittext1 = (edittext) findviewbyid (R. id. myedittext); // sets the prompt content edittext1.sethint when edittext is empty ("Enter AAAAA content ");//Set edittext event listening ....MasterProgramThe only key is to use edittext. onkeylistener is used to intercept the keyboard input events of edittext. You only need to override the onkey () method. In the onkey () method, set edittext. the text obtained by gettext () is displayed in textview. // New edittext. onkeylistener () and new onkeylistener () are the same as edittext1.setonkeylistener (New edittext. onkeylistener () {public Boolean onkey (view arg0, int arg1, keyevent arg2) {textview1.settext ("the content of the text box is" + edittext1.gettext (). tostring (); Return false ;}});}}
