Android: singleLine = "true"

Otherwise, press enter to [Search] and a new line will be entered.

2. mEditSearchUser. setOnKeyListener (new OnKeyListener (){

@ Override

Public boolean onKey (View v, int keyCode, KeyEvent event ){

If (keyCode = KeyEvent. KEYCODE_ENTER ){
// Hide the keyboard first
(InputMethodManager) getSystemService (INPUT_METHOD_SERVICE ))
. HideSoftInputFromWindow (SearchUserActivity. this. getCurrentFocus ()
. GetWindowToken (), InputMethodManager. HIDE_NOT_ALWAYS );
// Method used to perform the search operation. You can add the non-null judgment of mEditSearchUser to this method.
Search ();
}
Return false;
}
});

Private void search (){

String searchContext = mEditSearchUser. getText (). toString (). trim ();
If (TextUtils. isEmpty (searchContext )){
TipTools. Define toast (this, "the input box is empty. Enter ");
} Else {
// Call the search API method
SearchUser (searchContext );
}
