android set hidden the keyboard on press enter (in a EditText)

When my user press Enter on the virtual android "user validate entry!" keyboard my keyboard stay visible! (Why?)

Here my Java code...

private void initTextField() {
    entryUser = (EditText) findViewById(R.id.studentEntrySalary);
    entryUser.setOnKeyListener(new OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if (event.getAction() == KeyEvent.ACTION_DOWN) {
                switch (keyCode) {
                    case KeyEvent.KEYCODE_DPAD_CENTER:
                    case KeyEvent.KEYCODE_ENTER:
                        userValidateEntry();
                        return true;
                }
            }

          retu开发者_开发技巧rn true;
        }
    });
}

private void userValidateEntry() {
    System.out.println("user validate entry!");
}

... here my View

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content">
            <EditText android:id="@+id/studentEntrySalary" android:text="Foo" android:layout_width="wrap_content" android:layout_height="wrap_content" />
 </LinearLayout>

Maybe something wrong on my virtual device?

This should do it:

yourEditTextHere.setOnEditorActionListener(new OnEditorActionListener() {

        @Override
        public boolean onEditorAction(TextView v, int actionId,
                KeyEvent event) {
            if (event != null&& (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
                InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

                // NOTE: In the author's example, he uses an identifier
                // called searchBar. If setting this code on your EditText
                // then use v.getWindowToken() as a reference to your 
                // EditText is passed into this callback as a TextView

                in.hideSoftInputFromWindow(searchBar
                        .getApplicationWindowToken(),
                        InputMethodManager.HIDE_NOT_ALWAYS);
               userValidateEntry();
               // Must return true here to consume event
               return true;

            }
            return false;
        }
    });

Keep the singleLine="true" and add imeOptions="actionDone" to the EditText. Then in the OnEditorActionListener check if actionId == EditorInfo.IME_ACTION_DONE, like so (but change it to your implementation):

if (actionId == EditorInfo.IME_ACTION_DONE) {

                if ((username.getText().toString().length() > 0)
                        && (password.getText().toString().length() > 0)) {
                    // Perform action on key press
                    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(username.getWindowToken(),
                            0);
                    doLogin();
                }
            }

If you make the text box a single line (I believe the propery is called SingleLine in the layout xml files) it will exit out of the keyboard on enter.

Here you go: http://developer.android.com/reference/android/R.styleable.html#TextView_singleLine

I am create a custom component who extends AutoCompleteTextView, like in the example below:

public class PortugueseCompleteTextView extends AutoCompleteTextView {
...
@Override
public boolean onKeyPreIme(int keyCode, KeyEvent event) {
    if (event != null &&  (event.getKeyCode() == KeyEvent.KEYCODE_BACK)) {
        InputMethodManager inputManager =
                (InputMethodManager) getContext().
                        getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(
                this.getWindowToken(),
                InputMethodManager.HIDE_NOT_ALWAYS);
    }
    return super.onKeyPreIme(keyCode, event);
}

I am using this code in the AlertDialog.Builder, but is possible to be using to Activity.

just add this line in your edit text.

android:imeOptions="actionDone"'

you can specify the next edit text id to move to that edit text on click of the keyboard done button.
