Searching instead of breaking line - EditText

I'm making a dictionary. I want when I press "Enter", the EditText doesn't insert new line and do search instead. How to do it?

I tried OnKey, OnKeyDown, OnEditorAction but it doesn't work. When I press "Enter", EditText 开发者_开发知识库inserts a new line.

public boolean onEditorAction(final TextView v, final int actionId, final KeyEvent event) {
    System.out.println("OnEditor.");
    if (actionId == EditorInfo.IME_ACTION_SEARCH ||
            actionId == EditorInfo.IME_ACTION_DONE ||
            event.getAction() == KeyEvent.ACTION_DOWN &&
            event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
        System.out.println("OnEditor.");
    }

    return true;
}

Update: imeOption doesn't works.

Instead of the deprecated singleLine attribute you are supposed to use

android:inputType="text"

to force single line input.

You can also restrict edittext to single line using

android:singleLine="true"

You need to set the android:imeOptions attribute in your XML which will show the appropriate keyboard button. Then you can listen for the onEditorAction call.

add the following line to your edit text

android:imeOptions="actionSend|flagNoEnterAction"
