Android Enter event programming

Implement Android Press ENTER to hide the input keyboard, there are two ways:

1.) If the layout is multiple edittext, set android:singleline= "true" for each EditText control, and the floppy disk input key is next, until the last one gets the focus after it is done, after clicking Done, The floppy disk input keyboard is hidden. or set the Imeoptions property of the EditText android:imeoptions= "Actiondone", whether it is the last edittext or not, click Enter to hide the IME.

2.) Listen for the Enter event and write the event response for enter. Set the Onkeylistener of the text box, when KeyCode ==keyevent.keycode_enter, indicates that the ENTER key is pressed, you can write your own event response function.
