android set hidden the keyboard on press enter (in

Question

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;
                }
            }

          return 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?

Answer 1

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.

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();
                }
            }

Answer 3

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.

Answer 4

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;
        }
    });

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
